==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and an on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[#CV Addendum (Standard CV's)|CV Addendum (Standard CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Overview==
Bachmann’s new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and an on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [https://docs.tcsdcc.com/wiki/Bachmann_Venture_Cab_Car_(VIA_Rail)_-_HO_(2026_Run)#CV_Addendum_(Standard_CV's) CV Addendum (Indexed CV's)] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

==Overview==
Bachmann’s new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and an on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

Bachmann’s new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and an on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

Bachmann’s new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and an on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "5mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds

*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behavior matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Overview==
Bachmann’s all-new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with Audio Assist® for easy configuration without programming CVs. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS true CD-quality audio with 16-bit depth resolution at 44,100Hz
*Authentic and prototypical sounds
*Voice-guided Audio Assist® programming tool for easy set-up of almost all decoder functionality
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 4.5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements.” Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behaviour matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV182 bit 7 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 =19
*CV 203 = 144
*CV 204 = 251

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements." Listen as the train flies by at track speed when the Whoosh feature is enabled!

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behaviour matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV180 bit 2 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV180 bit 2 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [[Diesel Version 5:WOWDiesel Standard CV's|List of Diesel Version 5 Standard CV's]], and/or [[Diesel Version 5:WOWDiesel Indexed CV's|List of Diesel Version 5 Indexed CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring [[Diesel Version 5:CV 177|CV 177]].

To disable Function Pagination, set [[Diesel Version 5:CV 177|CV 177]] to a value of 0.{{Button Mapping Paged

==Overview==
Bachmann’s all-new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with Audio Assist® for easy configuration without programming CVs. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS true CD-quality audio with 16-bit depth resolution at 44,100Hz
*Authentic and prototypical sounds
*Voice-guided Audio Assist® programming tool for easy set-up of almost all decoder functionality
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 4.5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements” as well as new traction noises like “traction motor” and “traction motor gearbox." Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behaviour matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV182 bit 7 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 =19
*CV 203 = 144
*CV 204 = 251

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 =19
*CV 203 = 144
*CV 204 = 251

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 4.5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements” as well as new traction noises like “traction motor” and “traction motor gearbox." Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behaviour matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV182 bit 7 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 =19
*CV 203 = 144
*CV 204 = 251

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped C36-7 locomotive uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration and on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the GE C36-7 locomotive from Bachmann Trains brings all the sights and sounds of GE's iconic rumble to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*3 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*Directional steady/flashing ditch lights
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped C36-7 locomotive uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration and on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the GE C36-7 locomotive from Bachmann Trains brings all the sights and sounds of GE's iconic rumble to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*3 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*Directional steady/flashing ditch lights
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==NMRA CV 249 - Decoder Model ID Number==
TCS decoders are each assigned a unique identification number which is associated with the hardware/name of the decoder. This ID number is know as the Decoder Model, and is stored in CV249. The most common use for CV249 is by JMRI Decoder Pro, which uses this ID number to help identify and select the correct decoder definition is right for your decoder.

If you unsure what kind of decoder you have simply read the value in CV249 match it to its type in this table.

Diesel Version 5:Random Sounds

2026-04-24T20:12:20Z

JosephR:

There are four random sound modules in the WOWSound decoder.<br>
Each random sound module has its own timer but all of them are also controlled by a master timer in [[{{NAMESPACE}}:CV_139|CV139]]. If you want to adjust all of the random sound timers or find that you can't get the desired play frequency using the individual timers try adjusting the overall random sound timer
== Random Sound One ==
Random Sound One is reserved for use by the air compressor. The air compressor will play over time as air leaks out of the reservoir or whenever a lot of air is used for the train brakes or horn (try it out, its fun!)<br>
When the Prime mover is changed from [[{{NAMESPACE}}:Audio_Assist™|Audio Assist™]] the air compressor sound automatically changes to the prototypical compressor for that prime mover. The compressor assigned to Random Sound 1 can also be manually changed on Audio Assist menu 1.2 or through [[{{NAMESPACE}}:WOWDiesel_Indexed_CV's|CV programming]]. When adjusting the air compressor in Audio Assist be sure to select "Random Sound One" as the function your mapping a sound to.
<br>
The Frequency that Random Sound One plays (how leaky your air reservoir and linkage is!) is controlled by [[{{NAMESPACE}}:CV_141|CV141]]
== Random Sound two ==
Random Sound Two by default is an "Air Spitter"<br>
The frequency at which the random sound plays is controlled by [[{{NAMESPACE}}:CV_142|CV142]]
== Random Sound Three ==
Random Sound Three by default is unassigned<br>
The frequency at which the random sound plays is controlled by [[{{NAMESPACE}}:CV_143|CV143]]
== Random Sound Four ==
Random Sound Four by default is unassigned<br>
The frequency at which the random sound plays is controlled by [[{{NAMESPACE}}:CV_144|CV144]]

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped C36-7 locomotive uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration and on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the GE C36-7 locomotive from Bachmann Trains brings all the sights and sounds of GE's iconic rumble to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*3 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*Directional steady/flashing ditch lights
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped C36-7 locomotive uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration and on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the GE C36-7 locomotive from Bachmann Trains brings all the sights and sounds of GE's iconic rumble to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*3 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*Directional steady/flashing ditch lights
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Overview==
Bachmann’s new DCC sound-equipped Dash 8-40CW uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration, and on-board Keep-Alive® device for uninterrupted operation, even over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the GE Dash 8-40CW in HO-scale from Bachmann Trains brings all the sights and sounds of GE's iconic rumble diesel-electric locomotive to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*5 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*Directional steady/flashing ditch lights
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.

==Specific Features==
The SC-44 charger is at its heart a WOWDiesel decoder but has had some customization to make it specific to the SC-44 Charger locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the SC-44 Charger locomotive will sit still until a sufficient track voltage is present. Once the minimum voltage is met the locomotive will begin to move. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV.

'''Additional Sound Features'''

The SC-44 Charger locomotive features new sounds such as “Whoosh” and “station announcements” as well as new traction noises like “traction motor” and “traction motor gearbox." Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The SC-44 Charger supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The SC-44 Charger includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

'''New Lighting Features'''

The SC-44 Charger features a fully-functional emergency strobe light that operates prototypically. Send your DCC system into emergency and the engine will immediately stop and turn on the red strobe. Additionally you can also activate the “emergency brake” manually by engaging the TCS-exclusive Braking Feature fully with five rapid presses, after which the train will come to a quick stop and turn on the strobe.

The emergency strobe light also works in conjunction with the “crew alert” feature. The crew alert feature acts as a “dead mans” switch. If no user input is received after a set amount of time the alarm will sound giving the user short amount of time to enter input or else the train will go into emergency, brake, and come to a stop with the red emergency strobe flashing! When the crew alert feature is enabled, the emergency strobe will activate once the crew alert timer expires.

According to § 1.4.12 of the Siemens SC-44 Charger Operations Manual, the strobe lights function automatically when certain conditions are met. The white strobes will flash when the ditch lights are activated and headlights are at full brightness. TCS has implemented automatic and manual control modes for the white strobe lights. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the white strobe lights will behave as described in the Siemens manual section 1.4.12 while the strobe button is activated on the throttle (default Function 5). When Function 5 is activated, the strobe lights will turn on when both the headlight and ditch lights are active. If Function 5 is turned off, the strobe light will remain off regardless of current head and ditch light states. In manual control mode (CV182 bit 7 is OFF), headlight and ditch light status has no effect on the white strobes. The white strobe lights are controlled manually by the throttle button.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, you must first have a Charger decoder with a manufactured date which falls within or after the Second Run (After January 18th 2021). First Run Charger decoders do not support the option to disable Function Pagination. Set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 = 19
*CV 203 = 144
*CV 204 = 251

Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The SC-44 Charger supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The SC-44 Charger includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

'''New Lighting Features'''

The SC-44 Charger features a fully-functional emergency strobe light that operates prototypically. Send your DCC system into emergency and the engine will immediately stop and turn on the red strobe. Additionally you can also activate the “emergency brake” manually by engaging the TCS-exclusive Braking Feature fully with five rapid presses, after which the train will come to a quick stop and turn on the strobe.

The emergency strobe light also works in conjunction with the “crew alert” feature. The crew alert feature acts as a “dead mans” switch. If no user input is received after a set amount of time the alarm will sound giving the user short amount of time to enter input or else the train will go into emergency, brake, and come to a stop with the red emergency strobe flashing! When the crew alert feature is enabled, the emergency strobe will activate once the crew alert timer expires.

According to § 1.4.12 of the Siemens SC-44 Charger Operations Manual, the strobe lights function automatically when certain conditions are met. The white strobes will flash when the ditch lights are activated and headlights are at full brightness. TCS has implemented automatic and manual control modes for the white strobe lights. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the white strobe lights will behave as described in the Siemens manual section 1.4.12 while the strobe button is activated on the throttle (default Function 5). When Function 5 is activated, the strobe lights will turn on when both the headlight and ditch lights are active. If Function 5 is turned off, the strobe light will remain off regardless of current head and ditch light states. In manual control mode (CV182 bit 7 is OFF), headlight and ditch light status has no effect on the white strobes. The white strobe lights are controlled manually by the throttle button.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, you must first have a Charger decoder with a manufactured date which falls within or after the Second Run (After January 18th 2021). First Run Charger decoders do not support the option to disable Function Pagination. Set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 = 19
*CV 203 = 144
*CV 204 = 251

==Overview==
Bachmann’s all-new DCC sound-equipped Venture Cab Car uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with Audio Assist® for easy configuration without programming CVs. The WOWSound® sound package includes sounds for horn, bell, HVAC, station announcements, cooling fan, coupler close/release, brake release, and many more!

Loaded with prototypical features, the Venture Cab Car in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new design to your layout.

Features include:

*Siemens-approved design
*DCC sound-equipped for sound and directional lighting control
*Dual-mode NMRA-compliant decoder operates sound and lights on DCC or DC power
*TCS true CD-quality audio with 16-bit depth resolution at 44,100Hz
*Authentic and prototypical sounds
*Voice-guided Audio Assist® programming tool for easy set-up of almost all decoder functionality
*Directional headlights with "Rule 17" dimming operation enabled by default
*Interior passenger area lighting with DCC function control
*Forward-mounted High-beam light, with operation per prototype
*Directional marker lights
*Steady/alternate flashing ditch lights
*TCS' exclusive Function Pagination System
*Separately-applied windshield wipers, mirrors, and other detail parts

==Specific Features==
The Venture Cab Car decoder is at its heart a WOWDiesel decoder but has had some customization to make it similar to the SCV-42 [https://docs.tcsdcc.com/wiki/Bachmann_Spectrum_SCV-42_(VIA_Rail_Charger)_-_HO (VIA Rail Charger)] locomotive. The information below details where CV’s and operation differ from the standard Version 4.5 WOWDiesel decoder.

'''DC mode operation'''

When operating in DC mode, the cab Car will sit still and silent until a sufficient track voltage is present. Once the minimum voltage is met, the lights will come on. A connected SCV-42 Charger locomotive will begin to move around the same time. A horn blast and bell will activate automatically. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default and are controlled by the Automatic Sounds CV. For users with a consist of Cab Car and Charger locomotive, the Reverse Quill should be disabled on both decoders for more realistic operation.

'''Additional Sound Features'''

The Venture Cab Car features new sounds such as “Whoosh” and “station announcements” as well as new traction noises like “traction motor” and “traction motor gearbox." Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The Venture Cab Car supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum (Indexed CV's)|CV Addendum (Indexed CV's)]] section below for more information.

The Venture Cab Car includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

The Venture Cab Car is the first decoder from TCS to feature an industry-first feature straight from the prototype - the "3mph safety switch" - This feature will be active when the locomotive has the default horn set selected, or certain other prototype horns from Amtrak, such as the ACS-64 horn, or VIA Rail SC-42 horn. When any of the "high" versions of these horns are selected, the feature will activate. When the feature is active, the locomotive will automatically switch between the low-pressure and high-pressure outputs to the horn depending on the speed. The speed at which this change from low to high pressure happens is configurable in the decoder, but by default is roughly 3mph scale speed. This behaviour matches prototypical operations on most railroads, where only the low-pressure horn is available when stationary or at low speed, in order to reduce the volume of the horn while in passenger stations for example.

'''New Lighting Features'''

The SCV-42 Charger locomotive features a "high beam" headlight, positioned centrally on the front of the engine below the two primary headlights. According to the Siemens Venture Cab Car Operations Manual, the high beam function can only be turned on when the headlight is active and not dimmed. TCS has implemented automatic and manual control modes for the high beam. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the high beam will behave as described in the Siemens manual. When Function 5 in Light Mode is activated, the high beam will turn on only when the headlight is active and not dim. If Function 5 in Light Mode is turned off, the high beam will remain off regardless of current headlight state. In manual control mode (CV182 bit 7 is OFF), headlight status has no effect on the high beam. The high beam is controlled manually by the throttle button 5 in Light Mode.

==Button Mappings==
The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our [https://www.tcsdcc.com/_files/ugd/559cd7_d3fbf8b528984a7a8c59874c9dcdd508.pdf Comprehensive Programming Guide], [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWDiesel V4 Programming Guide], and/or [[NMRA Standard CV's|List of Standard CV's]].

===TCS Function Pagination System===
The {{PAGENAME}} locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

*Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
*Press button 5 on your throttle/controller
*The decoder will activate function 5 + 10 (page 2 offset) = 15

'''''Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.'''''

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see ''Page 19'' of the [https://www.tcsdcc.com/_files/ugd/559cd7_dfb8199e41ca41e185196092ef121643.pdf WOWSound Diesel Version 4 Complete Programming Guide]. This document can be used in conjunction with the [[Bachmann Spectrum SC-44 (Charger) - HO#CV Addendum .28Indexed CV.27s.29|Indexed CV Addendum]] below.

To disable Function Pagination, set the values of the Indexed CV as follows:

*CV 201 = 4
*CV 202 =19
*CV 203 = 144

Throttle Release Notes

2026-03-10T13:45:20Z

JosephR:

==Instructions for Updating==
For instructions on how to apply the latest update to your UWT-100, please refer to our [[Instructions for Updating WiFi-Enabled Throttles]].

Listed below are the release notes for the available firmware versions, in descending order starting with the most recent. The most recent version of software will also include all of the features and other changes listed in every previous releases.

==Release 3.8==
Release 3.8 makes the following changes and improvements:

===Feature Additions & Changes===
*Adds packet filtering to the built-in hub of the throttles exposed on port 12021. (Note that this is not a commonly used feature.)
*[UWT-100 only] Improves knob handling such that the throttle does not jump back to speed step 1 following a scroll down to 0, even if the mechanics are springy.
*[UWT-50 only] Adds speed increment/decrement/increment fast/decrement fast as possible features of the thumb switches.

===Bug Fixes===
*Fixes a rare crash in the consist editing window.
*Fixes a rare crash in the menu window.
*Fixes Protocol Support reports on LCC to include Firmware Upgrade support.

<br />

==Release 3.6==
Release 3.6 makes the following changes and improvements:

===Feature Additions & Changes===
*Updates text on the button configuration tabs in the Configuration window shown by JMRI.
*[UWT-50P only] Makes the throttle remember whether it was in yard mode during power off / power on, including inactivity timeout.

===Bug Fixes===
*Ensures that when a throttle connects, both emergency off and emergency stop state gets correctly displayed.
*Fixes warnings displayed by JMRI when the Configuration screen is closed.
*Fixes crashes and standards-compliancy issues caused by unknown LCC messages.
*Fixes LCC behavior upon alias conflicts.
*Fixes an issue that occasionally caused the last used DCC accessory number to be printed in the middle of the main screen.
*[UWT-50P only] Fixes runaway train at power on when the knob was not at zero.

<br />

==Release 3.4==
Release 3.4 makes the following changes and improvements to the UWT-100:

===Feature Additions & Changes===

*Adds a configuration option for disabling or changing the sensitivity of the ballistic tracking (acceleration) for the encoder knob. ''Menu > 8 Settings > 1 Throttle Settings > 3 Drive Settings > Encoder Ballistics > Off/Low/Mid/High.'' The default of this setting will be Mid, whereas throttle software until 3.2 had the same behavior as High. Changing the setting to Off will disable all ballistics and the knob will control the speed at a constant rate with the rotation.

===Bug Fixes===

*Fixes bug when the locomotive speed would jump to 126 unexpectedly after the throttle has been sitting idle for some time.
*The sensitivity of the thumbwheel is adjusted down in the text entry window to match that of the menus. This will make it easier to select individual characters and enter text.

===Miscellaneous Changes===

*Updated DCC accessory addresses according to the newest standard RCN-213 and NMRA S-9.1.2 from 2023. This changes the behavior of turnout address 2045-2047, and extends the maximum to turnout address 2048. Turnouts 1-2044 did not change as part of this update.
*Fixed corner case when the same locomotive is selected on both sides in Dual Throttle mode and speed changes would not update each other. The speed and direction displayed will now follow each other as expected.
*Various fixes regarding LCC standards compliance. The Producer Identified Messages are updated. The CDI XML has an additional null terminator. Some non-user-visible but non-compliant parts in the XML are fixed.

<br />

==Release 3.2==
This release adds support for the magnetic encoder. The type of the encoder hardware is auto-detected, and printed in the About This Throttle page (Menu > 7).

===Feature Additions & Changes===

*Adds support for Magnetic Encoder in UWT-100.
*Removes ballistic tracking when using the thumbwheel in the menus and text entry window.

===Bug Fixes===

*Bug fixes and performance improvements in specific situations.
*LCC turnout change screen: documents in the help text that ENTER will toggle the accessory and exit back to the main screen. Fixes a rare bug when it forgot to exit.
*Fixes crash when the LCC Command Station was slow in responding to requests during a select locomotive operation.

<br />

==Release 3.0==
UWT Firmware Version 3.0 is a scheduled software release for the UWT-100 and UWT-50 which adds full support for the CS-105 at initial release. Most of the changes focus on improvements and bug fixes in LCC mode. Continue reading to see the full list of changes.
{| class="wikitable"
|'''UWT Firmware Version 3.0 or newer is REQUIRED to operate a CS-105 when connected in LCC mode. Use of an older UWT firmware version with a CS-105 will result in most features of the system not working properly, and error messages and connection issues.'''
|}

===CS-105 Feature Support===
'''NOTE:''' All of the items below only apply when the UWT is connected to a CS-105 in LCC mode, and do not apply when in the WiThrottle Protocol connection mode. Many of the features described in this section are feature integrations with the Command Station. Listed below are ''some'' of the highlight features. For more detailed information on these features and how to use them, please refer to our [[CS-105|Wiki Documentation for the CS-105]].

Fun Fact: If your layout is run with assistance from JMRI, you can control your trains with a UWT in LCC mode using JMRI. In order to do this, you MUST be running JMRI Version 5.0 or newer otherwise you will not have the feature support. JMRI can be used to run an LCC/OpenMRN “Hub” (similar to a WiThrottle server) to connect an unlimited number of UWT’s to your CS-105.

'''Programming Track'''

To access this user interface, navigate to ''Menu>4 CV Programming>2 Programming Track''

[Image]

NOTE: CV programming is only available when connected to a CS-105 in LCC mode.

'''Roster Data Entry for Locomotives'''

Add, modify, and remove locomotives in the CS-105’s Internal Roster. Configure options such as:

*Name of locomotive
*Speed Step Mode
*Names/Labels for each button-controlled function
*Button-controlled functions which respond while in a system-controlled consist

To set up and access roster settings, first select a locomotive, then navigate to ''Menu>8 Settings>3 Roster Settings''

Train name and metadata on the display of the current throttle will refresh automatically after editing Roster Settings.

'''Miscellaneous Train Selection and Control Changes'''

*Adds support for selecting a locomotive using Marklin-Motorola (trinary) protocol by adding double-zero before the locomotive address. Example: to select M/M address 25, press the Loco key, type in “0025” and press ENTER. Note that entering “025” will select DCC long address 25.
*Function labels used for soft key settings will match CS-105 software version 1.0. As an example, when Button [:.] is configured under Throttle Settings > Change Buttons for “Coupler Open”, and the CS-105 presents a F9 as “Uncouple”, then pressing [:.] will trigger F9 on the locomotive.

'''LCC Throttle “Heartbeats”'''

*Adds support for heartbeats in the LCC train protocol.

'''NOTE:''' The CS-105 requires heartbeats from a throttle by default. When a UWT throttle with software prior to this version controls a train in LCC mode, the operator will find that the train speed resets to zero after ~10 seconds of running. This is resolved in the 3.0 release. If UWT’s with older software versions should not need to be used with a CS-105, heartbeat must be disabled in the command station settings.

Notifies LCC train to stop sending heartbeat requests when the throttle is powered down (intentionally or due to inactivity timeout).

'''Accessory Control'''

*Makes accessory screen in LCC mode work similarly to WiThrottle Protocol mode:
**Pressing ENTER will toggle-and-exit
**Pressing the Turnout Button will toggle and stay in the accessory screen.
*Adds support for triggering Command Station Macros on the CS-105. To trigger a macro, press the turnout button, enter zero followed by the macro number, then enter. As an example, type “042 ENTER” to run macro number 42.
*Adds support for turnout addresses up to 2047 according to the RCN-213 standard.

'''Short Circuit Indicator'''

*Adds an indicator to the top-right of the screen whenever a short circuit is present. This icon will appear instead of the WiFi signal strength indicator.

[Image]

'''NOTE:''' This feature will only work when connected to a TCS CS-105 and TCS Boosters.

'''Fast Clock'''

*Adds Fast Clock support in LCC mode. In LCC mode the throttle can automatically detect whether there is a Fast Clock generator available on LCC.

===Bug Fixes for LCC Connections===

*Fixes an issue where trailing locomotives in LCC consists did not respond to function button presses.
*Fixes a rare network-related lockup in LCC mode.
*Fixes incorrect display on screen when selecting a locomotive fails.
*Fixes incorrect display of address in the DCC Address Programming screen when a locomotive is being reprogrammed from a long address to a short address.
*Fixes a crash that was dependent on the serial number of the throttle.

===Miscellaneous Changes===
Items in this section apply regardless of the connection mode (LCC or WiThrottle Protocol).

*Improved the behaviour of the UWT-50P when the knob is moved while the user is in the menu screens. After exiting the menu, the knob will have to be first returned near the current speed before the locomotive speed can be changed. This is the same behavior as just after selecting or recalling a locomotive which avoids a sudden change of speed.
*Menu Name for Menu>8 Settings>2 Consist Functions changed to “2 WT Consist Funcs” for clarity purposes. This menu is used to handle function routing when creating and running In-Throttle Consists with the UWT, and does not apply or change any settings in LCC mode. The menu title was changed to reflect this to avoid confusion with consist function settings in the CS-105 Internal Roster.
*Improved clarity of some error messages
*Improved Help Text in many areas, and added new Help Text for new menu items.

<br />

==Release 2.4==
Release 2.4 is a scheduled software release for the UWT-100 that adds additional features, brings improvements to existing features based on the feedback of our users, and fixes some minor bugs. Release 2.4 is the first production firmware version for the UWT-50.

===Feature Additions & Changes===
'''Fast Clock'''

*Under the WiThrottle Protocol mode, the throttle will display the Fast Clock if the WiThrottle Server supports it. The Fast Clock display works with all known fast clocks, but support will depend on the connection to your layout and supporting infrastructure.
*12 hour and 24 hour clock formats are select-able in the settings.
*The Fast Clock displays on the right-hand-side. If the layout is in E-STOP, or Dual Throttle Mode (UWT-100 only) is enabled, that covers up the fast clock display.
*If the Fast Clock is not in use at the layout you are operating at, but the display is still turned on in the throttle settings, there is a possibility that a clock will display. By default, JMRI will create a “fast” clock which matches the current time of day and has a rate of 1:1. These clocks can be disabled in the JMRI WiThrottle Server settings (applies to all throttles), or individually on a per-throttle basis as stated above.
*To enable the Fast Clock automatic display, go to: Throttle Settings > Fast Clock > Show Fast Clock. (Default = OFF)

'''Remappable Button (Softkey) Changes'''

*To select F0 to F28 as fixed locomotive function number for a remappable button, enter the chosen number in the new “F0 - F28” menu. Found at: Menu > Settings > Throttle Settings > Change Buttons > [Button]
*Further to the above, The long list of entries F0, F1, … F28 is now removed from the "Common Functions" list in order to improve performance and give a better user experience. Common Functions list still exists, and consists of only named functions now.
*After selecting a remappable button in the Change Buttons menu, the current setting is now printed in the title.
*“Stop” is a new selectable function that can be assigned to any remappable button. The behavior is that it sets the locomotive speed to zero (with normal deceleration).
*The operations on the 1-dot, 2-dot, 3-dot and 4-dot keys are slightly rearranged on the UWT-100 in certain auxiliary screens to be aligned with the UWT-50 and be more intuitive to use. For example a confirmation dialog is now presented as “Yes | No” instead of “No | Yes”.

'''Accessory Mode Control Improvements'''

*Added new "toggle-and-exit" feature to the Accessory Window. ''This feature was recommended through user feedback.''

To use the toggle-and-exit feature, first select an accessory (e.g. typing in a number), then press the Enter button to toggle the accessory and immediately exit the Accessory Window. If you want to toggle and ''remain'' in the Accessory Window (for example to change multiple accessories), select the accessory, and then press the Accessory (turnout icon) button to toggle, OR use the "Normal" and "Reverse" (N/On / R/Off) buttons on the 2-dot and 3-dot keys.

*The Accessory button no longer exits to the drive window if an accessory number is selected. Use the "Esc" key to exit back to the drive window.

[Image]

===LCC-related Changes===
(Changes listed below do not affect connections over WiThrottle protocol)

*Added an assisted/automatic DCC Address Programming process. This can be found when connected through LCC under: Menu > CV Programming > DCC Address.
*This menu allows one to view the current address(es) of a locomotive on the Programming Track, set a short or long DCC Address, as well as view, set and clear CV19 Consist Address in an automatic and easy-to-use manner.
*Removed an unneeded step after accessing Menu > Settings > Roster Settings.
*Updated Consist Function Routing menus to support the advanced capabilities of LCC consisting in the CS-105.

===Bug Fixes===

*Fixed an issue where trying to add a new WiFi profile beyond the supported maximum (seven) did not prompt the user that their profiles were full. The throttle ''appeared'' to take the 8th WiFi but it would not take/would not work correctly; instead, the throttle now prompts the user before adding a new WiFi, when their profiles are full, to delete a profile before proceeding.
*After locking in (latching) a speed in yard mode on the UWT-100 and UWT-50E, entering and exiting the menu incorrectly changed the display.
*Removed an incorrect and out-of-context message from the built-in website from the Add WiFi box.

===Miscellaneous Changes===

*In the text entry window, added visual clarification between the space and underscore characters. This avoids confusion where entering a WiFi name or password with underscores appearing to be not accepted by the throttle.
*In the text entry window, the most common punctuation characters (dot, minus, underscore and space) now appear on almost all pages when entering text.
*Accelerated (“ballistic”) behavior of the encoder-based thumb wheel is now disabled in menus. ''This change was made in response to user feedback.''
*Removed scanning on WiFi channel 13. This channel is not universally accessible due to regulatory constraints. Use channels 1 to 11 for maximum compatibility.
*Added a "refresh" button to the "About This Throttle" menu. This allows you to periodically refresh the window to update info displayed there. This can help users troubleshoot connectivity issues by having a "live update" on signal strength, SSID, IP, etc.
*Added some new icons to the user interface

===Firmware Synchronicity With UWT-50===
From this point forward, the firmware release numbers between the UWT-50 and UWT-100 throttles are always going to be the same. This means that the same release numbers will have the same features, performance and bug fixes. Most changes made can affect both devices, but there is also the possibility of having new updates which primarily address features or bugs on one device only. TCS' release schedule for firmware updates on the UWT-100 and UWT-50 is scheduled to include updates for both devices in synchronicity.
<br />

==Release 2.0==
Release 2.0 is a major software release that adds new features, brings improvements in different areas based on the feedback of our users and our development schedule, and fixes some minor bugs.

===Feature Additions & Changes===
The TCS UWT-100 throttle can now be used to control two locomotives at the same time. Both locomotives will be visible on the screen with their address, speed and direction.

'''Dual Throttle Mode Features:'''

*You can enable or disable Dual Throttle Mode by going Menu > Operations > Dual Throttle or typing [≡][2][6] on the keypad.
*While Dual Throttle Mode is active, the Recall ''softkey'' (default ['''·''']) will display as ‘Swap’. Swap may be used to flip the positions of the two throttles. '''NOTE:''' If you have changed the settings for your remappable buttons (softkeys) and have removed or overwritten the Recall option, but would still like to use Swap, you may use the Recall Menu instead and select the first option at the top of the list. Using the keypad would go like this: [≡][1][1]
*The single chevron keys will operate the right throttle’s speed while the double chevron keys, the thumbwheel, the direction key, and the function buttons operate the left throttle. Using the Select Loco key or Menu > Recall will replace the locomotive on the left throttle.
*If needed, a softkey (such as ['''∷''']) can be re-configured to operate as the Dual Direction button for the secondary throttle (In the Settings > Change Buttons menu, pick “Dual Direction” from the Common Functions list).
*Both throttles can be independently set to drive consists. The consist change operations manipulate the consist on the left throttle.
*Both throttles can be independently set to Yard Mode. We recommend using the right throttle to control a locomotive in Yard Mode because the direction can be controlled by using exclusively the chevron keys without the need to swap sides or reconfigure a soft key for the Dual Direction function.

We especially recommend Dual Throttle Mode for operators working a yard and users who would like to monitor and control two locomotives at the same time.

'''Accessory and Route Support'''

*The Accessory Control Screen now has separate keys for setting a turnout to Normal or Reversed. Pressing ENTER will “throw” the switch or toggle the accessory if the underlying system supports it. More details can be found in the new [[UWT-100#The%20.E2.80.9CHelp.E2.80.9D%20Button|Help Text]] for the Accessory Control Screen.
*The soft buttons in the Accessory Control Screen will now highlight to show you that your command was sent to the layout.
*'''Controlling turnouts over an LNWI connection is now supported'''. Press the Accessory key, enter the turnout number, then press the N/On or R/Off keys to set the turnout to Normal (aka. Closed) or Reversed (aka. Thrown). “Toggling” or throwing a turnout using the Enter key is not supported by the LNWI.
*'''Controlling Routes via JMRI'''. The UWT-100 throttle is now able to show and set Routes entered into JMRI. Routes will show when pressing the Accessory key in the list after the turnouts. The list can be restricted to show routes only by typing 0 on the keypad, after which typing more digits will further restrict the shown routes. A route from the list can be activated by scrolling to highlight it, then pressing the [··] (Select) key. Blind typing is also supported, for example if you have a route called “Yard entry 28”, you can trigger that with [ACCY] [0] [2] [8] [ENTER]. NCE macros can be operated using the Accessory Control Screen with the Appropriate JMRI Configuration.

'''Recall Functionality Tweaks'''

*The throttle will now remember if a locomotive was in [[Yard Mode]] through power cycles and Recall button presses. This allows for seamless transitions between a switcher in Yard Mode and a road locomotive in normal mode when using the Recall key -- the throttle will automatically switch to the last used mode for each locomotive. The throttle will remember the Yard Mode setting for all recently used locomotives that are still in the Recall list (up to 20), and apply it even if you select a recently used locomotive by address.
*Certain system connections via JMRI are incorrectly reporting locomotives acquired as zero speed and all functions off, even if the locomotive is running on the layout. This makes the quick switching between locomotives using the Recall button very difficult to use. We recommend using Dual Throttle Mode which does not exhibit this issue and makes switching between two locomotives much faster.
*If you regularly need to switch between ''more than two locomotives'', we added a workaround in Settings > Throttle Settings > Drive Settings > Workaround for Recall 0 Speed. This will make the throttle keep all locomotives which were selected in the current session in a hidden consist, causing JMRI to correctly remember the locomotive state. You can still explicitly release a locomotive with Menu > Operations > Release/Dispatch. '''WARNING:''' this behavior can make most command stations really unhappy, so make sure you only enable it if absolutely necessary. So far we’ve only seen this issue on the NCE PowerCab and PowerHouse Pro when using it via JMRI and the NCE USB or Serial connections. The WFD-30 module from WiFiTrax does successfully report speed and function status to the throttle, and does not require this workaround. Use this feature at your own risk. If transitioning between layouts and command stations, turn this feature on or off as necessary.

===Bug Fixes===

*Fixed incorrect scrolling when exiting the Advanced parameters menu in the Network Profile.
*Fixed incorrect line breaks on the Locomotive Steal dialog.
*Fixed bug where it was impossible to use the E-STOP button to turn track power on when using an LNWI connection.
*Fixed bug where selecting Menu > Network > Current Network > Reconnect showed a locomotive on the screen that could not be controlled. The locomotive is now correctly re-acquired after the reconnect.
*Fixed bug where an unintuitive error message was left on the screen in Offline mode.
*Fixed bug when an empty menu item was shown in the Main Menu under some circumstances.
*Fixed bug where selecting an accessory from the search results was sometimes impossible if it was the only result in the list.
*Fixed bug where the menu labels in the Consist Functions menu displayed 1 for F0.
*Fixed bug where “Connected to {WiFi}” message was stuck on screen under some circumstances.
*Fixed bug where F0/headlight was not correctly displayed after acquiring a locomotive under some circumstances.
*Fixed bug where the direction sign was not correctly shown in Yard Mode under some circumstances.
*Fixed bug where the double chevrons failed to repeatedly change speed when held down in normal speed control mode, whereas single chevrons worked with repeats.

===Miscellaneous Changes===

*Added Help text to the Select Loco and Select Accessory screens. Use the [?] button on these screens to access the help.
*Yard Mode On/Off can now be assigned as a function to any of the eight remappable buttons (including the soft keys), allowing you to turn Yard Mode on or off on any locomotive at any time with one button press.
*In Yard Mode the double chevrons are permanently assigned to control the locomotive; any other functions specified for the double chevrons will be active only in Standard mode. Similarly, in Dual Throttle Mode the single chevrons are permanently assigned to the right side throttle.
*Added a menu option to display and control track power in Menu > Settings > Track Power. This menu option can control layout power on any system that supports it. Track power may still be controlled via the E-STOP button if configured as a more convenient option.
*The main screen will display when the throttle is in Offline mode. You may now exit Offline mode by selecting Menu > Network > Current Network > Reconnect, or by selecting a specific profile and the Connect Now command. Previously you had to turn off the throttle to exit Offline mode.
*The throttle now supports pressing two buttons at the same time. For example while holding down the horn button, a chevron key in Yard Mode can be pressed. This also allows you to drive two locomotives in Dual Throttle Mode at the same time, including when both locos are in Yard Mode.
*When the throttle gets into the automatic network discovery after turning on (this happens after a few seconds if reconnecting fails), it will print the name of the WiFi network it connected to on the top to aid in troubleshooting.

== Release 1.4 ==
Release 1.4 is a minor software release that fixes critical bugs and brings minor improvements in certain areas based on the feedback of our users.

=== Feature Additions & Changes ===
'''Recall functionality'''

* The number of available recall slots was increased from 8 to 20.
* The locomotive which is currently selected on the throttle is no longer shown in the Menu > Recall list.
* The Menu > Recall list title is updated to state clearly when the list is empty.
* All entries can now be deleted from the Recall List.

'''Emergency Stop functionality'''

Based on user feedback, we made the Emergency Stop functionality safer to use and more predictable in behavior across different systems. We made the following changes to protect your valuable equipment from accidents:

* An Emergency Stop can no longer be released by changing the speed, such as touching the wheel by accident.
* In the default configuration your locomotive speed will be set to zero when engaging the Emergency Stop. This will prevent your locomotive from accelerating when you release the Emergency Stop. Note: when operating an entire show layout from a single throttle, we recommend configuring the Emergency Stop button to operate only the layout power option, and disabling the “Current Locomotive” E-Stop functionality. In this mode all locomotives retain their speed setting from prior to the E-Stop.
* It is no longer possible to '''release''' the Emergency Stop while navigating the menus or other auxiliary screens. You can still '''engage''' the E-Stop from any screen by pressing the red button (one or more times).
* The throttle will now ask for confirmation before releasing the Emergency Stop. This makes releasing the Emergency Stop a multiple-button-press process to ensure it is intentional. On the confirmation screen we will remind you what speed your locomotive will have after releasing the E-Stop.
* Fixed bug where setting a locomotive to Emergency Stop then selecting a new locomotive caused the new locomotive to be incorrectly reported to be in Emergency Stop mode.

'''Park mode'''

* Added a new action: Menu > Operations > Park/Un-Park Current Loco. This engages/releases the Emergency Stop function on the currently selected locomotive, regardless of the setting of the red E-Stop button. This can be used by operators whose train needs to remain stopped in a siding to prevent accidental movements of the train. The speed buttons and knob/wheel will not work while parked.

=== Bug Fixes ===

* Fixed bug where single-stepping speed increase could not go past speed 49 on certain WiThrottle Protocol based systems.
* Fixed bug in Yard Mode where changing direction using the yard mode buttons sometimes caused a brief movement of the locomotive in the previous direction.
* Fixed bug where the throttle would not recall the last locomotive after a power cycle in certain situations.

JosephR: JosephR moved page UWT-100 Release Notes to Throttle Release Notes

==Instructions for Updating==
For instructions on how to apply the latest update to your UWT-100, please refer to our [[Instructions for Updating WiFi-Enabled Throttles]].

Listed below are the release notes for the available firmware versions, in descending order starting with the most recent. The most recent version of software will also include all of the features and other changes listed in every previous releases.

==Release 3.4==
Release 3.4 makes the following changes and improvements to the UWT-100:

===Feature Additions & Changes===

*Adds a configuration option for disabling or changing the sensitivity of the ballistic tracking (acceleration) for the encoder knob. ''Menu > 8 Settings > 1 Throttle Settings > 3 Drive Settings > Encoder Ballistics > Off/Low/Mid/High.'' The default of this setting will be Mid, whereas throttle software until 3.2 had the same behavior as High. Changing the setting to Off will disable all ballistics and the knob will control the speed at a constant rate with the rotation.

===Bug Fixes===

*Fixes bug when the locomotive speed would jump to 126 unexpectedly after the throttle has been sitting idle for some time.
*The sensitivity of the thumbwheel is adjusted down in the text entry window to match that of the menus. This will make it easier to select individual characters and enter text.

===Miscellaneous Changes===

*Updated DCC accessory addresses according to the newest standard RCN-213 and NMRA S-9.1.2 from 2023. This changes the behavior of turnout address 2045-2047, and extends the maximum to turnout address 2048. Turnouts 1-2044 did not change as part of this update.
*Fixed corner case when the same locomotive is selected on both sides in Dual Throttle mode and speed changes would not update each other. The speed and direction displayed will now follow each other as expected.
*Various fixes regarding LCC standards compliance. The Producer Identified Messages are updated. The CDI XML has an additional null terminator. Some non-user-visible but non-compliant parts in the XML are fixed.

<br />

==Release 3.2==
This release adds support for the magnetic encoder. The type of the encoder hardware is auto-detected, and printed in the About This Throttle page (Menu > 7).

===Feature Additions & Changes===

*Adds support for Magnetic Encoder in UWT-100.
*Removes ballistic tracking when using the thumbwheel in the menus and text entry window.

===Bug Fixes===

*Bug fixes and performance improvements in specific situations.
*LCC turnout change screen: documents in the help text that ENTER will toggle the accessory and exit back to the main screen. Fixes a rare bug when it forgot to exit.
*Fixes crash when the LCC Command Station was slow in responding to requests during a select locomotive operation.

<br />

==Release 3.0==
UWT Firmware Version 3.0 is a scheduled software release for the UWT-100 and UWT-50 which adds full support for the CS-105 at initial release. Most of the changes focus on improvements and bug fixes in LCC mode. Continue reading to see the full list of changes.
{| class="wikitable"
|'''UWT Firmware Version 3.0 or newer is REQUIRED to operate a CS-105 when connected in LCC mode. Use of an older UWT firmware version with a CS-105 will result in most features of the system not working properly, and error messages and connection issues.'''
|}

===CS-105 Feature Support===
'''NOTE:''' All of the items below only apply when the UWT is connected to a CS-105 in LCC mode, and do not apply when in the WiThrottle Protocol connection mode. Many of the features described in this section are feature integrations with the Command Station. Listed below are ''some'' of the highlight features. For more detailed information on these features and how to use them, please refer to our [[CS-105|Wiki Documentation for the CS-105]].

Fun Fact: If your layout is run with assistance from JMRI, you can control your trains with a UWT in LCC mode using JMRI. In order to do this, you MUST be running JMRI Version 5.0 or newer otherwise you will not have the feature support. JMRI can be used to run an LCC/OpenMRN “Hub” (similar to a WiThrottle server) to connect an unlimited number of UWT’s to your CS-105.

'''Programming Track'''

To access this user interface, navigate to ''Menu>4 CV Programming>2 Programming Track''

[Image]

NOTE: CV programming is only available when connected to a CS-105 in LCC mode.

'''Roster Data Entry for Locomotives'''

Add, modify, and remove locomotives in the CS-105’s Internal Roster. Configure options such as:

*Name of locomotive
*Speed Step Mode
*Names/Labels for each button-controlled function
*Button-controlled functions which respond while in a system-controlled consist

To set up and access roster settings, first select a locomotive, then navigate to ''Menu>8 Settings>3 Roster Settings''

Train name and metadata on the display of the current throttle will refresh automatically after editing Roster Settings.

'''Miscellaneous Train Selection and Control Changes'''

*Adds support for selecting a locomotive using Marklin-Motorola (trinary) protocol by adding double-zero before the locomotive address. Example: to select M/M address 25, press the Loco key, type in “0025” and press ENTER. Note that entering “025” will select DCC long address 25.
*Function labels used for soft key settings will match CS-105 software version 1.0. As an example, when Button [:.] is configured under Throttle Settings > Change Buttons for “Coupler Open”, and the CS-105 presents a F9 as “Uncouple”, then pressing [:.] will trigger F9 on the locomotive.

'''LCC Throttle “Heartbeats”'''

*Adds support for heartbeats in the LCC train protocol.

'''NOTE:''' The CS-105 requires heartbeats from a throttle by default. When a UWT throttle with software prior to this version controls a train in LCC mode, the operator will find that the train speed resets to zero after ~10 seconds of running. This is resolved in the 3.0 release. If UWT’s with older software versions should not need to be used with a CS-105, heartbeat must be disabled in the command station settings.

Notifies LCC train to stop sending heartbeat requests when the throttle is powered down (intentionally or due to inactivity timeout).

'''Accessory Control'''

*Makes accessory screen in LCC mode work similarly to WiThrottle Protocol mode:
**Pressing ENTER will toggle-and-exit
**Pressing the Turnout Button will toggle and stay in the accessory screen.
*Adds support for triggering Command Station Macros on the CS-105. To trigger a macro, press the turnout button, enter zero followed by the macro number, then enter. As an example, type “042 ENTER” to run macro number 42.
*Adds support for turnout addresses up to 2047 according to the RCN-213 standard.

'''Short Circuit Indicator'''

*Adds an indicator to the top-right of the screen whenever a short circuit is present. This icon will appear instead of the WiFi signal strength indicator.

[Image]

'''NOTE:''' This feature will only work when connected to a TCS CS-105 and TCS Boosters.

'''Fast Clock'''

*Adds Fast Clock support in LCC mode. In LCC mode the throttle can automatically detect whether there is a Fast Clock generator available on LCC.

===Bug Fixes for LCC Connections===

*Fixes an issue where trailing locomotives in LCC consists did not respond to function button presses.
*Fixes a rare network-related lockup in LCC mode.
*Fixes incorrect display on screen when selecting a locomotive fails.
*Fixes incorrect display of address in the DCC Address Programming screen when a locomotive is being reprogrammed from a long address to a short address.
*Fixes a crash that was dependent on the serial number of the throttle.

===Miscellaneous Changes===
Items in this section apply regardless of the connection mode (LCC or WiThrottle Protocol).

*Improved the behaviour of the UWT-50P when the knob is moved while the user is in the menu screens. After exiting the menu, the knob will have to be first returned near the current speed before the locomotive speed can be changed. This is the same behavior as just after selecting or recalling a locomotive which avoids a sudden change of speed.
*Menu Name for Menu>8 Settings>2 Consist Functions changed to “2 WT Consist Funcs” for clarity purposes. This menu is used to handle function routing when creating and running In-Throttle Consists with the UWT, and does not apply or change any settings in LCC mode. The menu title was changed to reflect this to avoid confusion with consist function settings in the CS-105 Internal Roster.
*Improved clarity of some error messages
*Improved Help Text in many areas, and added new Help Text for new menu items.

<br />

==Release 2.4==
Release 2.4 is a scheduled software release for the UWT-100 that adds additional features, brings improvements to existing features based on the feedback of our users, and fixes some minor bugs. Release 2.4 is the first production firmware version for the UWT-50.

===Feature Additions & Changes===
'''Fast Clock'''

*Under the WiThrottle Protocol mode, the throttle will display the Fast Clock if the WiThrottle Server supports it. The Fast Clock display works with all known fast clocks, but support will depend on the connection to your layout and supporting infrastructure.
*12 hour and 24 hour clock formats are select-able in the settings.
*The Fast Clock displays on the right-hand-side. If the layout is in E-STOP, or Dual Throttle Mode (UWT-100 only) is enabled, that covers up the fast clock display.
*If the Fast Clock is not in use at the layout you are operating at, but the display is still turned on in the throttle settings, there is a possibility that a clock will display. By default, JMRI will create a “fast” clock which matches the current time of day and has a rate of 1:1. These clocks can be disabled in the JMRI WiThrottle Server settings (applies to all throttles), or individually on a per-throttle basis as stated above.
*To enable the Fast Clock automatic display, go to: Throttle Settings > Fast Clock > Show Fast Clock. (Default = OFF)

'''Remappable Button (Softkey) Changes'''

*To select F0 to F28 as fixed locomotive function number for a remappable button, enter the chosen number in the new “F0 - F28” menu. Found at: Menu > Settings > Throttle Settings > Change Buttons > [Button]
*Further to the above, The long list of entries F0, F1, … F28 is now removed from the "Common Functions" list in order to improve performance and give a better user experience. Common Functions list still exists, and consists of only named functions now.
*After selecting a remappable button in the Change Buttons menu, the current setting is now printed in the title.
*“Stop” is a new selectable function that can be assigned to any remappable button. The behavior is that it sets the locomotive speed to zero (with normal deceleration).
*The operations on the 1-dot, 2-dot, 3-dot and 4-dot keys are slightly rearranged on the UWT-100 in certain auxiliary screens to be aligned with the UWT-50 and be more intuitive to use. For example a confirmation dialog is now presented as “Yes | No” instead of “No | Yes”.

'''Accessory Mode Control Improvements'''

*Added new "toggle-and-exit" feature to the Accessory Window. ''This feature was recommended through user feedback.''

To use the toggle-and-exit feature, first select an accessory (e.g. typing in a number), then press the Enter button to toggle the accessory and immediately exit the Accessory Window. If you want to toggle and ''remain'' in the Accessory Window (for example to change multiple accessories), select the accessory, and then press the Accessory (turnout icon) button to toggle, OR use the "Normal" and "Reverse" (N/On / R/Off) buttons on the 2-dot and 3-dot keys.

*The Accessory button no longer exits to the drive window if an accessory number is selected. Use the "Esc" key to exit back to the drive window.

[Image]

===LCC-related Changes===
(Changes listed below do not affect connections over WiThrottle protocol)

*Added an assisted/automatic DCC Address Programming process. This can be found when connected through LCC under: Menu > CV Programming > DCC Address.
*This menu allows one to view the current address(es) of a locomotive on the Programming Track, set a short or long DCC Address, as well as view, set and clear CV19 Consist Address in an automatic and easy-to-use manner.
*Removed an unneeded step after accessing Menu > Settings > Roster Settings.
*Updated Consist Function Routing menus to support the advanced capabilities of LCC consisting in the CS-105.

===Bug Fixes===

*Fixed an issue where trying to add a new WiFi profile beyond the supported maximum (seven) did not prompt the user that their profiles were full. The throttle ''appeared'' to take the 8th WiFi but it would not take/would not work correctly; instead, the throttle now prompts the user before adding a new WiFi, when their profiles are full, to delete a profile before proceeding.
*After locking in (latching) a speed in yard mode on the UWT-100 and UWT-50E, entering and exiting the menu incorrectly changed the display.
*Removed an incorrect and out-of-context message from the built-in website from the Add WiFi box.

===Miscellaneous Changes===

*In the text entry window, added visual clarification between the space and underscore characters. This avoids confusion where entering a WiFi name or password with underscores appearing to be not accepted by the throttle.
*In the text entry window, the most common punctuation characters (dot, minus, underscore and space) now appear on almost all pages when entering text.
*Accelerated (“ballistic”) behavior of the encoder-based thumb wheel is now disabled in menus. ''This change was made in response to user feedback.''
*Removed scanning on WiFi channel 13. This channel is not universally accessible due to regulatory constraints. Use channels 1 to 11 for maximum compatibility.
*Added a "refresh" button to the "About This Throttle" menu. This allows you to periodically refresh the window to update info displayed there. This can help users troubleshoot connectivity issues by having a "live update" on signal strength, SSID, IP, etc.
*Added some new icons to the user interface

===Firmware Synchronicity With UWT-50===
From this point forward, the firmware release numbers between the UWT-50 and UWT-100 throttles are always going to be the same. This means that the same release numbers will have the same features, performance and bug fixes. Most changes made can affect both devices, but there is also the possibility of having new updates which primarily address features or bugs on one device only. TCS' release schedule for firmware updates on the UWT-100 and UWT-50 is scheduled to include updates for both devices in synchronicity.
<br />

==Release 2.0==
Release 2.0 is a major software release that adds new features, brings improvements in different areas based on the feedback of our users and our development schedule, and fixes some minor bugs.

===Feature Additions & Changes===
The TCS UWT-100 throttle can now be used to control two locomotives at the same time. Both locomotives will be visible on the screen with their address, speed and direction.

'''Dual Throttle Mode Features:'''

*You can enable or disable Dual Throttle Mode by going Menu > Operations > Dual Throttle or typing [≡][2][6] on the keypad.
*While Dual Throttle Mode is active, the Recall ''softkey'' (default ['''·''']) will display as ‘Swap’. Swap may be used to flip the positions of the two throttles. '''NOTE:''' If you have changed the settings for your remappable buttons (softkeys) and have removed or overwritten the Recall option, but would still like to use Swap, you may use the Recall Menu instead and select the first option at the top of the list. Using the keypad would go like this: [≡][1][1]
*The single chevron keys will operate the right throttle’s speed while the double chevron keys, the thumbwheel, the direction key, and the function buttons operate the left throttle. Using the Select Loco key or Menu > Recall will replace the locomotive on the left throttle.
*If needed, a softkey (such as ['''∷''']) can be re-configured to operate as the Dual Direction button for the secondary throttle (In the Settings > Change Buttons menu, pick “Dual Direction” from the Common Functions list).
*Both throttles can be independently set to drive consists. The consist change operations manipulate the consist on the left throttle.
*Both throttles can be independently set to Yard Mode. We recommend using the right throttle to control a locomotive in Yard Mode because the direction can be controlled by using exclusively the chevron keys without the need to swap sides or reconfigure a soft key for the Dual Direction function.

We especially recommend Dual Throttle Mode for operators working a yard and users who would like to monitor and control two locomotives at the same time.

'''Accessory and Route Support'''

*The Accessory Control Screen now has separate keys for setting a turnout to Normal or Reversed. Pressing ENTER will “throw” the switch or toggle the accessory if the underlying system supports it. More details can be found in the new [[UWT-100#The%20.E2.80.9CHelp.E2.80.9D%20Button|Help Text]] for the Accessory Control Screen.
*The soft buttons in the Accessory Control Screen will now highlight to show you that your command was sent to the layout.
*'''Controlling turnouts over an LNWI connection is now supported'''. Press the Accessory key, enter the turnout number, then press the N/On or R/Off keys to set the turnout to Normal (aka. Closed) or Reversed (aka. Thrown). “Toggling” or throwing a turnout using the Enter key is not supported by the LNWI.
*'''Controlling Routes via JMRI'''. The UWT-100 throttle is now able to show and set Routes entered into JMRI. Routes will show when pressing the Accessory key in the list after the turnouts. The list can be restricted to show routes only by typing 0 on the keypad, after which typing more digits will further restrict the shown routes. A route from the list can be activated by scrolling to highlight it, then pressing the [··] (Select) key. Blind typing is also supported, for example if you have a route called “Yard entry 28”, you can trigger that with [ACCY] [0] [2] [8] [ENTER]. NCE macros can be operated using the Accessory Control Screen with the Appropriate JMRI Configuration.

'''Recall Functionality Tweaks'''

*The throttle will now remember if a locomotive was in [[Yard Mode]] through power cycles and Recall button presses. This allows for seamless transitions between a switcher in Yard Mode and a road locomotive in normal mode when using the Recall key -- the throttle will automatically switch to the last used mode for each locomotive. The throttle will remember the Yard Mode setting for all recently used locomotives that are still in the Recall list (up to 20), and apply it even if you select a recently used locomotive by address.
*Certain system connections via JMRI are incorrectly reporting locomotives acquired as zero speed and all functions off, even if the locomotive is running on the layout. This makes the quick switching between locomotives using the Recall button very difficult to use. We recommend using Dual Throttle Mode which does not exhibit this issue and makes switching between two locomotives much faster.
*If you regularly need to switch between ''more than two locomotives'', we added a workaround in Settings > Throttle Settings > Drive Settings > Workaround for Recall 0 Speed. This will make the throttle keep all locomotives which were selected in the current session in a hidden consist, causing JMRI to correctly remember the locomotive state. You can still explicitly release a locomotive with Menu > Operations > Release/Dispatch. '''WARNING:''' this behavior can make most command stations really unhappy, so make sure you only enable it if absolutely necessary. So far we’ve only seen this issue on the NCE PowerCab and PowerHouse Pro when using it via JMRI and the NCE USB or Serial connections. The WFD-30 module from WiFiTrax does successfully report speed and function status to the throttle, and does not require this workaround. Use this feature at your own risk. If transitioning between layouts and command stations, turn this feature on or off as necessary.

===Bug Fixes===

*Fixed incorrect scrolling when exiting the Advanced parameters menu in the Network Profile.
*Fixed incorrect line breaks on the Locomotive Steal dialog.
*Fixed bug where it was impossible to use the E-STOP button to turn track power on when using an LNWI connection.
*Fixed bug where selecting Menu > Network > Current Network > Reconnect showed a locomotive on the screen that could not be controlled. The locomotive is now correctly re-acquired after the reconnect.
*Fixed bug where an unintuitive error message was left on the screen in Offline mode.
*Fixed bug when an empty menu item was shown in the Main Menu under some circumstances.
*Fixed bug where selecting an accessory from the search results was sometimes impossible if it was the only result in the list.
*Fixed bug where the menu labels in the Consist Functions menu displayed 1 for F0.
*Fixed bug where “Connected to {WiFi}” message was stuck on screen under some circumstances.
*Fixed bug where F0/headlight was not correctly displayed after acquiring a locomotive under some circumstances.
*Fixed bug where the direction sign was not correctly shown in Yard Mode under some circumstances.
*Fixed bug where the double chevrons failed to repeatedly change speed when held down in normal speed control mode, whereas single chevrons worked with repeats.

===Miscellaneous Changes===

*Added Help text to the Select Loco and Select Accessory screens. Use the [?] button on these screens to access the help.
*Yard Mode On/Off can now be assigned as a function to any of the eight remappable buttons (including the soft keys), allowing you to turn Yard Mode on or off on any locomotive at any time with one button press.
*In Yard Mode the double chevrons are permanently assigned to control the locomotive; any other functions specified for the double chevrons will be active only in Standard mode. Similarly, in Dual Throttle Mode the single chevrons are permanently assigned to the right side throttle.
*Added a menu option to display and control track power in Menu > Settings > Track Power. This menu option can control layout power on any system that supports it. Track power may still be controlled via the E-STOP button if configured as a more convenient option.
*The main screen will display when the throttle is in Offline mode. You may now exit Offline mode by selecting Menu > Network > Current Network > Reconnect, or by selecting a specific profile and the Connect Now command. Previously you had to turn off the throttle to exit Offline mode.
*The throttle now supports pressing two buttons at the same time. For example while holding down the horn button, a chevron key in Yard Mode can be pressed. This also allows you to drive two locomotives in Dual Throttle Mode at the same time, including when both locos are in Yard Mode.
*When the throttle gets into the automatic network discovery after turning on (this happens after a few seconds if reconnecting fails), it will print the name of the WiFi network it connected to on the top to aid in troubleshooting.

== Release 1.4 ==
Release 1.4 is a minor software release that fixes critical bugs and brings minor improvements in certain areas based on the feedback of our users.

* Fixed bug where setting a locomotive to Emergency Stop then selecting a new locomotive caused the new locomotive to be incorrectly reported to be in Emergency Stop mode.

'''Park mode'''

* Added a new action: Menu > Operations > Park/Un-Park Current Loco. This engages/releases the Emergency Stop function on the currently selected locomotive, regardless of the setting of the red E-Stop button. This can be used by operators whose train needs to remain stopped in a siding to prevent accidental movements of the train. The speed buttons and knob/wheel will not work while parked.

=== Bug Fixes ===

* Fixed bug where single-stepping speed increase could not go past speed 49 on certain WiThrottle Protocol based systems.
* Fixed bug in Yard Mode where changing direction using the yard mode buttons sometimes caused a brief movement of the locomotive in the previous direction.
* Fixed bug where the throttle would not recall the last locomotive after a power cycle in certain situations.

==NMRA CV 249 - Decoder Model ID Number==
TCS decoders are each assigned a unique identification number which is associated with the hardware/name of the decoder. This ID number is know as the Decoder Model, and is stored in CV249. The most common use for CV249 is by JMRI Decoder Pro, which uses this ID number to help identify and select the correct decoder definition is right for your decoder.

If you unsure what kind of decoder you have simply read the value in CV249 match it to its type in this table.

==NMRA CV 28 - Bi-Directional Communication Configuration (RailCom®)==
This CV is used to configure decoder’s bi-directional communication characteristics when RailCom is enabled in [[{{NAMESPACE}}:CV_29|CV 29]].

If the decoder does not support a feature contained in this table, it shall not allow the corresponding bit to be set improperly. E.G. if a decoder does not support RailCom, this CV will read 0 and will not accept any values to be programmed to it. Additionally, the decoder should not allow you to enable a feature within the table below which is not supported.

''Note: The table above is based upon the RailCom Specification RCN-217 and RCN-225 as of 01-16-2023 and as such is potentially subject to change. Additionally, the last column in this table "supported by TCS" is only true for current production decoders which support RailCom, and may be untrue for specific decoders and/or decoder versions ([[CV 7]], or [[Diesel Version 5:CV 110|CV 110]]/[[Diesel Version 5:CV 111|CV 111]]) designed using an older revision of RCN-217.''

''* Decoders prior to [[CV 7]] version 97 only support Channel 1 broadcast for [[CV 1]] short address.''

==Overview==
This page lists the numbers and names for all of the Configuration Variables defined by the NMRA Standards, including manufacturer-unique ones, used in TCS decoders.
{| class="wikitable"
|'''NOTE:''' This page refers only to TCS Non-sound decoders Version 88 to [current Version], as well as all WOWSound decoders Version 4.x.
|}
You can read the NMRA Standards for Configuration Variables (CV's) (Document No. S-9.2.2) for yourself on the NMRA website: [https://www.nmra.org/index-nmra-standards-and-recommended-practices NMRA Standards and Recommended Practices]
{| class="wikitable"
|'''NOTE:''' ''Not all CV's listed on this page are supported by TCS, and not all supported CV's are universally supported by all products. For example, [[CV 28|RailCom® configurations]], [[:Category:Lights|lighting output assignment]], and other features which require hardware support may not be applicable to your decoder. Pay special attention to the CV Addendums for your specific decoder. If you are unsure what your decoder is, you can read [[CV 249]] the Decoder Hardware Model Identifier. '''If you are unsure if your decoder supports a feature''', visit the specific product page for your decoder on [https://tcsdcc.com/ TCS' Website] for a full list of features.''

==NMRA CV 249 - Decoder Model ID Number==
TCS decoders are each assigned a unique identification number which is associated with the hardware/name of the decoder. This ID number is know as the Decoder Model, and is stored in CV249. The most common use for CV249 is by JMRI Decoder Pro, which uses this ID number to help identify and select the correct decoder definition is right for your decoder.

If you unsure what kind of decoder you have simply read the value in CV249 match it to its type in this table.

Support - Decoder Version

2025-07-24T20:31:54Z

JosephR:

This page offers support on how to identify your TCS decoder hardware and version information, as well as the manufactured date. The information on this page pertains ''specifically'' to TCS decoders.

==Identifying Your Decoder Type==

===Verifying the Manufacturer===
Start by identifying the decoder as a TCS decoder by reading the [https://www.nmra.org/manufacturer-id-numbers Manufacturer ID] [[CV 8]]. '''<u>TCS' Manufacturer ID Number is 153.</u>'''

If your command station AND decoder supports [[Support - RailCom®|RailCom]]®, you can read CV's on the main. Otherwise, you will need to use a DCC Programming Track. If you are having issues with your programming track, see our [[Support - DCC Programming Track|Help Article]] on the subject.

===Identifying the Decoder Hardware===
Once you have confirmed that [[CV 8]] is 153, you now know that the decoder in question is indeed a TCS decoder! You can further identify your decoder by checking the Hardware ID number, stored in [[CV 249]]. Refer to the lookup table on the wiki page for [[CV 249]] to compare the number in your decoder.

''Question: How do I know if my decoder is new/current?''

See the section below on [[Support - Decoder Version#Identifying the Version Number|Identifying the Version Number]]

==Identifying the Date of Manufacturing==
TCS decoders are created with a manufactured date stored in their memory. The Manufacturing Date can be read out from the decoder using three CV's:

*CV 250 - Month of Manufacturing
*CV 251 - Day of Manufacturing
*CV 252 - Year of Manufacturing

WOWSound decoders with [[Audio Assist®]] can speak the manufactured date, as well as other version information. Refer to the Audio Assist Tree Diagram for the decoder type and Version for instructions on how to do this.

==Identifying the Version Number==
TCS Version numbers and Version identification varies between product lines. Below are listed the various ways that TCS identifies version information based on the product type:

===Non-Sound Decoders===
TCS Non-sound decoders use a single software/firmware version number which is incremented every time TCS patches a major bug or introduces a feature. This version identifier information is stored in [[CV 7]].

Hardware versions can be identified by looking at the decoder itself. A revision number or letter will be assigned and displayed on ''most'' (but not all) TCS decoders. If a decoder does not have a written Revision number on it, it can be assumed to be Rev1/RevA.

===WOWSound Decoders - V4 and Older===
TCS sound decoders use a an "architecture" or over-arching "major" version number which is incremented every time TCS introduces major changes in hardware. This version identifier information is stored in [[CV 7]]. WOWSound decoders Version 4.x and older do not individually track software/firmware updates.

Sound decoders are further identified by "Sound Set," meaning the library of sounds included on the decoder. In WOWSound Version 4, this is used as a "sub-major" version as in "4.5" or "4.6". The Sound Set version is stored in [[CV 248]], and correlates to a particular List of Sounds for the decoder type. See the list on the wiki page for [[CV 248]] for links to the sound lists for each version.

===WOWSound Decoders - V5===
