NOTE: Most of the items on this page also apply to Version 1. Look for specific notes for Version-2-specific additions which would not be included in Version 1.

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:

  1. Determine the "drawer" or primary index value, such as 4.
  2. Add a value of 100 to the primary index (CV 201). EG "4" = 104
  3. Set CV 202 to the secondary index location (same as described above).
  4. 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.
  5. 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!

List of WOWElectric Version 2 Indexed CV's

Index 1:X - Sound Button Remapping

Set CV 201 and CV 202 to a value shown in the table below to select a button to map a sound to. Then, use CV 203 and CV 204 to select the sound you would like to map to the button.

Note: it is highly recommended that you use Audio Assist to remap sound functions, as it requires much less effort and no lookup tables!

4:20 Idling Sound Selection VERSION 2+ ONLY - Valid Values are 0 or 1
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 Rotate Bell / Bell Selection Uses CV 204 to select the Bell type from the List of Sounds.
4:24 - 4:26 (Not Used)
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 (Not Used)
4:30 BEMF Low Calibration (Forward) (Not Used)
4:31 BEMF High Calibration (Forward) (Not Used)
4:32 (Not Used)
4:33 BEMF Low Calibration (Reverse) (Not Used)
4:34 BEMF High Calibration (Reverse) (Not Used)
4:35 - 4:42 (Not Used)
4:43 DC Mode Start Voltage Voltage at which the decoder will power on and begin making sound
4:44 DC Mode Bell Cutout Voltage Voltage at which the DC mode bell will stop playing, the higher the value the higher the voltage threshold.
4:45 Automatic DCC 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 DC Mode motor hysteresis – When the engine starts moving in DC mode the increased current draw may cause some oscillation.

If so, increase the value in this CV until the oscillation goes away. Using too high of a value will result in the decoder powering down before the motor stops running.

If the engine is going through a power on reset try increasing Sound CV 43 (Voltage at which the Engine will power up at while in DC mode)

4:47 (Not Used)
4:48 Traction Motor Minimum Volume The minimum volume the traction motor is allowed to be at Speed Step 1
4:49 (Not Used)

4:52 Mainline Mode Acceleration Default = 20
4:53 Mainline Mode Deceleration Default = 60
4:54 Traction Motor Fade-Out Speed Step VERSION 2+ ONLY Speed step at which the Traction Motor sound will be completely faded into Gearbox sound.
4:55 Traction Motor Gearbox Starting Speed Step VERSION 2+ ONLY Speed step at which the Traction Motor Gearbox sound will begin fading into the Traction Motor sound.
4:56 Traction Motor Gearbox Minimum Volume VERSION 2+ ONLY The volume at which the Traction Motor Gearbox sound will begin to fade in from.

NOTE: It is not recommended to change this CV value; Recommended Maximum is 10

4:57 (Not Used)
4:58 High Horn Threshold (5mph safety switch) VERSION 2+ ONLY Speed step at which the decoder will begin playing the High-Pressure Horn. When the speed is set to below this value, the decoder will use the low-pressure horn. A value of 0 disables this feature, and the high horn will always play. A value of 1 will only play the low horn when stationary.

(Valid Values = 0-126)

NOTE: This feature only applies to specific horns, and does not apply to all horn sets available on this decoder.

4:59 Traction Motor Blower Selection VERSION 2+ ONLY Selects which Traction Motor Blower sound is played while moving

0 = Siemens Traction Motor Blower 1 | 1 = Siemens Traction Motor Blower 2 | 2 = Siemens Traction Motor Blower 3

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!
