Explanation of Indexed CV's
"Indexed CV's" are a method which a decoder can use to store and change more configuration options than could be possible using the 256 Standard CV's. TCS Non-sound decoders do not use Indexed CV's, since all of the configuration options can be squeezed into the Standard CV's. In WOWSound Version 4 and older decoders, TCS uses an indexed CV method which uses CV 201, 202, 203, and 204, which are described in detail below. All four of these CV's combined work as a method to "index" and manipulate the more complicated configuration options with many many possible options such as Mapping Sounds to Buttons.
How to Use Indexed CV's
Think of CV 201 through 204 as a filing cabinet. To make a change to a "file" in the "filing cabinet" you need to know the drawer and folder number where that file is. You also need to know what the info in that file is, or what you want it to be.
CV 201
CV 201 acts like the drawer - this is a "coarse" location of the information you want to edit. We use this to indicate the type of setting you would like to change.
For example, changes made to sound options and sound behaviour settings are in "drawer" number 4. Another example would be CV 201 = 6 for changing sound volumes.
CV 202
CV 202 acts like the "folder" within the "drawer" (CV 201) in which the setting (or "file" in this analogy) lives. CV 202 indicates what specific type of change you would like to make.
For example, if CV 201 is 4, and CV 202 is 19, this indicates that you would like to reconfigure the "User Options" settings. Another example would be CV 201 = 1 and CV 202 = 5, which would map a sound to Button 5.
CV 203
CV 203 is the "high byte" of the data/setting, and can vary in behaviour and usefulness depending on the situation. For some settings ("files"), the number of available options is less (0-255), meaning that this CV is not necessary and not used. In these cases, it should be set to 0. In some cases, any other random/erroneous value will not affect anything.
In bit-wise CV's like the User Options, or settings with more than 256 available setpoints however, CV 203's value WILL affect said setting, and should always be verified to be correct and taken into account before proceeding. Neglecting CV203 in some circumstances will result in erroneous programming changes that may affect other settings you were not intending to change.
CV 204
CV 204 Is used as the final step in the process. Programming a value into this CV will use the information/data in CV203 and CV204 to make a change to the setting as indicated by CV201 and CV202. Only after programming CV 204 with a value will the changes you made actually take place. You can freely manipulate CV 201, 202, and 203 without any affect taking place until you program CV 204.
Reading Indexed CV's
Note that all of the above steps are for writing to an indexed CV. In order to read the value from an Indexed CV, you need to follow these steps:
- Determine the "drawer" or primary index value, such as 4.
- Add a value of 100 to the primary index (CV 201). EG "4" = 104
- Set CV 202 to the secondary index location (same as described above).
- Program CV 204 to a value of 0, or any other bogus value. The value of CV 203 is irrelevant and can be skipped. After writing any value to CV 204, the decoder will fetch the data from the index you selected (CV 201:CV 202), and place the value(s) into CV 203 and CV 204.
- Immediately after writing to CV 204, you can read CV 204 and/or CV 203. CV 203 may not necessarily be in use, so it may return a 0, but CV 204 will always have some sort of data in it, including 0, which can be valid data.
Sounding too complicated? We agree! That's why we created Audio Assist®, and why we also offer Programming Tools which can be used to generate all of these values for you!

| 4:13 | Brake Grinding Noise Start Speed | Speed step at which "squeals" stop and "grinding" starts while braking. Brake grinding noises are sounds more accurate to low speeds and heavy brake application.
Range of Values is 0-126. A Value of 0 disables brake grinding and only uses brake squeal. Default = 15 |
| 4:14 | Dual-Enabled Functions | For functions F0F-F12, set bit to have a function button available in both Light Mode and Sound Mode.
*Default is F0F, F0R, and F8 (mute) dual-enabled. Default (XXX00010 00000011) = 515 (1:3) |
| 4:15 | WOWSteam V4.6 ONLY | See Below |

Default = 100 (X:100) |
| 4:17 | Rod Clank Set Selection | Determines which set of Rod clank sounds are played. The number of Rod Clank sound sets is determined by the Sound List. |
| 4:18 | Cylinder Cox Auto Turn-on Time | Sets how long the locomotive must be stationary before the cylinder cox will come on automatically the next time the locomotive starts moving.
Valid Range of values 1 - 65535 Default = 256 (1:0) |

(8) Enable Articulated Chuff (9) (Not Used) (10) Reverse Directional Whistles (11)* Enable Power Braking (12)* Enable Momentum Mode Audio Feedback (13)* Enable Johnson Bar Audio Feedback (14) Enable "Function Pagination" ||***WOWSteam Version 4.6 ONLY*** (15) [reserved] *Default (X0111000 11111000) = 14584 (56:248) |
| 4:20 | Articulated Chuff Slip Rate | Determines how frequently articulated chuffs slip in and out of sync. The higher the number the more frequently it happens.
Valid values are 0-255 Default = 240 (X:240) |
| 4:21 | Automatic Audio Shut-off Timer | This feature will automatically mute the decoder after the set period of time. To completely disable this feature, see Index 4:19 "User Options." This feature will extend the life of your decoder by muting the sound when stationary without any user input received. A value of 256 equals approximately three minutes.
Valid range of values is 1-65535 Default = 1200 (4:176) - Approximately 15 Minutes |
| 4:22 | Not Used | |
| 4:23 | Minimum Chuff Volume | This setting will set the minimum volume the chuff volume can fall to, regardless of the BEMF/load. Changing this setting will prevent the sound from behaving prototypical, but can force the decoder to always "chuff chuff chuff" as long as it is moving.
Valid range of values is 0 - 32767 Default = 0 (chuff/throttle can shut off completely) |
| 4:24 | Rotate Bell / Bell Selection | Uses CV 204 to select the Bell type from the List of Sounds. |
| 4:25 | Grade Crossing Quill Options | TCS records multiple grade crossing quills, and puts up to three of them in the decoder. This CV's selection controls which quills will play when the Grade X Quill Button is pressed.
(0)* Short Quill, (1)* Medium Quill (2)* Long Quill (3 - 6) Not used (7) Randomize Quill Play Order If a value of zero is entered, the short quill is defaulted to. In order to disable the whistle quill function, the button mapping for Grade X Quill must be overwritten or disabled. Default = 7 (X:7) |
| 4:26 | Cylinder Cox Set | Determines which set of cox sounds are active
NOTE: Using CV programming to assign a cylinder cox sound to a button will put the cylinder cocks sound type on that button, but might not set up the correct set. I.E. if you remap the "cylinder cox set 2" sound onto a button, but don't change this CV, that button will play a "cylinder cox set 1" instead. Changing this CV will affect any button or buttons already mapped with the Cylinder Cox sound type. Valid values are 1-2 Default = 1 (X:1) |
| 4:27 | Idling Sounds Selection | Determines which "Idling Sounds" sound plays while the locomotive is idle.
Valid values are determined by the Sound List. |
| 4:28 | Not Used | |
| 4:29 | Chuff Volume Change Time | Controls how fast the chuff volume can change from one level to another in response to a change in the load. This setting effectively adds "hysteresis" to the chuff volume if you feel the locomotive's chuff sound response is too sensitive and changes too quickly. A change of "1" adds or subtracts approximately 0.5 milliseconds to the responsiveness. This setting only affects the responsiveness when coasting at a set speed, and does not affect the performance and responsiveness when changing speed. See 4:32 "Chuff Volume Velocity Factor" for more info.
Default = 4500 (17:148) | (Approximately 2.25 seconds transition time from min to max) |
| 4:30 | BEMF Low Calibration (Forward) | |
| 4:31 | BEMF High Calibration (Forward) | |
| 4:32 | Chuff Volume Velocity Factor | |
| 4:33 | BEMF Low Calibration (Reverse) | |
| 4:34 | BEMF High Calibration (Reverse) | |
| 4:35 | Rod Clank Volume from BEMF | At the calculated minimum BEMF volume (BEMF Low Calibration) rod clank will be at full volume (rod clank type volume) and will fade away as the load increases. This CV is a percentage above the BEMF Low Calibration value that the rod clank will cut out.
Valid values are 0-100 Default = 30 (X:30) |
| 4:42 | Throttle Mode Selection | 0 = Traditional Throttle Mode
1 = Prototype Throttle Mode This setting controls how the chuff sound behaves: In "traditional" mode, the chuff volume is constant and determined by the "Chuff" Sound Type Volume. Snifters will play at their maximum programmable volume when the throttle is shut off, rod clank will not play at all. In "Prototype" throttle mode, the chuff volume is determined by the velocity, speed, BEMF/load, and calibration settings. The snifter valve and rod clank volume are also controlled dynamically by prototype throttle mode. Snifters will play when the throttle is deemed to be "off" and rod clank will start playing when the throttle is deemed to be appropriate (See Index 4:35) Default = 1 (Prototype Throttle Mode) |
| 4:43-4:46 | Not Used | |
| 4:47 | Thermal Overload Limit | ***WOW501 ONLY***
This CV sets the temperature at which the decoder will trip the thermal overload. It is not recommended to adjust this CV unless otherwise guided to do so by TCS technical support. If the thermal overload is tripping, your decoder is overheating! |
| 4:48 | DC Mode Quill Delta - Regulated Supply Mode | Default = 431 |
| 4:49 | WOWSteam V4.6 ONLY | See Below |
| 4:50 | Switching Mode Acceleration | Default = 5 |
| 4:51 | Switching Mode Deceleration | Default = 5 |
| 4:52 | Mainline Mode Acceleration | Default = 20 |
| 4:53 | Mainline Mode Deceleration | Default = 60 |
New Indexed CV's Unique to WOWSteam Version 4.6
| Indexed CV | Description | |
|---|---|---|
| NOTE: ALL OF THE INDEXED CV NUMBERS LISTED ABOVE IN THE SAME PRIMARY INDEX (4:X) STILL APPLY. THE CV'S LISTED IN THIS TABLE ARE ADDITIONS OR REVISIONS TO THE PREVIOUS TABLE | ||
| 4:15 | DC Mode Sounds Selection | (0)* DC mode automatic bell enabled
(1)* DC mode Forward Sound (2)* DC mode Reverse Sound (3)* DC mode stop sound (4)* DC mode quill enabled (5-15) NU *Default is all on. Default (XXXXXXXX XXX11111) = 31 (X:31) |
| 4:41 | DC Mode Chuff Volume | Sets the chuff volume level while in DC mode. If you are using a high power speaker and an power pack with poor regulation, loud chuffs can cause a significant drop in voltage. Lowering the maximum chuff volume can alleviate this issue.
Default = 5888 |
| 4:43 | DC Mode Start Voltage - Regulated Supply Mode | Default = 2400 |
| 4:44 | DC Mode Bell Cutout Voltage - Regulated Supply Mode | Default = 2525 |
| 4:45 | Automatic Bell Cutout Speed | DCC speed step above which the bell will stop playing (when enabled to play automatically).
Default = 15 |
| 4:46 | DC Mode Motor Hysteresis - Regulated Supply Mode | Default = 600 |
| 4:48 | DC Mode Quill Delta - Regulated Supply Mode | Default = 431 |
| 4:49 | Track Voltage BEMF Offset Factor | Default = 0 |
| 4:54 | DC Mode Max ADC Value - Regulated Supply Mode | Sets the expected maximum ADC value the decoder can expect to see when running in Analog mode. This gives the decoder a range that can be used to determine which speed to go depending on the track voltage. By default=, this CV is set to the maximum resolution size, which means the decoder will max out at about 14.5V on the rails. This CV will not help for DC power packs with higher max outputs than 15V, but for max outputs below 15V, the speed step range can be tuned; additionally, going above the ADC range, or increasing this CV, can limit the speed step at full throttle. This often does sound nicer, and gives more of a range in the "nice chuff rate zone" where speed is limited but enjoy-ability is increased.
Range of values is 0-4250. Recommended absolute minimum value is 2800. This CV MUST NOT be less than or equal to the Motor Start Voltage Default = 4250 (16:154) |
| 4:66 | DC Mode Start Voltage - Unregulated Supply Mode | Default = 2816 |
| 4:67 | DC Mode Motor Hysteresis - Unregulated Supply Mode | Default = 1250 |
| 4:68 | DC Mode Motor Hysteresis - Unregulated Supply Mode | Default = 12 |
| 4:69 | DC Mode Bell Cutout Voltage - Unregulated Supply Mode | Default = 2500 |
| 4:70 | DC Mode Quill Delta - Unregulated Supply Mode | Default = 1000 |
| 4:72 | DC Mode Speed Step Hysteresis - Regulated Supply Mode | Default = 8 |
Index 6:X - Sound Type Volumes
Set CV 201 to 6 and CV 202 to the desired Volume Level (x), then set CV 204 to the value of the Sound Type you want to change. (CV 203 is unused and should be Zero.) The Sound Type Numbers are listed in the List of Sounds for a specific project. There are typically 30 sound types or less.
Note: it is highly recommended that you use Audio Assist to change sound type volume levels, as it requires much less effort and no lookup tables!
