NMRA CV 29 - Configuration Data #1
This CV is used to set up or enable basic functions of your decoder such as direction, speed step modes, enable/disable DC operation, and select the active address type. See the table below for more information on the settings controlled by this CV.
To determine which functions are active, use the table below and combine the values of the functions you would like to have active, and program the sum into CV 29. Fun Fact: TCS also offers a Calculator Tool
| CV 29 - Configuration Data #1 | ||||
|---|---|---|---|---|
| Bit | Feature | Description | Default | Value |
| 0 | "Forward" Direction Selection | This setting can be used to invert the polarity of the motor when the decoder receives a "forward" direction command (in DCC mode only).
This setting offers a software-level fix if the decoder or motor has been wired backwards, instead of re-wiring the engine. Direction-sensitive functions, such as the motor AND directional headlights will be reversed so that they line up with the locomotive’s new forward direction. Note: This setting stacks with other related settings such as the Consist Direction setup, allowing you to have double-negatives in your configuration. |
OFF | 1 |
| 1 | Speed Step Mode (28/128) |
This setting selects the speed step mode used by the decoder. This setting is not affected by your command station's throttle setting.
When enabled, 128 speed step mode is active - the decoder will interpolate 128 speed step mode from 28 speed steps if your command station is not configured for 128 speed step mode. |
ON | 2 |
| 2 | Analogue (DC) Operation | If this setting is enabled, the decoder will operate when DC power is applied. If this setting is disabled, the decoder will not operate when DC power is applied.
The functionality of your decoder is based on your DC Mode Settings. |
ON | 4 |
| 3 | Bi-Directional Communication (RailCom) | This setting determines whether the decoder will send or receive information over RailCom. See Bi-Directional Communication Configuration for more details | ON | 8 |
| 4 | Speed Curve Selection | This setting will switch from using the 3-Point Speed Curve (CV 2, CV 5, and CV 6) when "OFF" to using the 28-Point Speed Curve (CV 67 through CV 94) when "ON"
(Note: Even with the this setting enabled, CV 2 will always be enabled for use to "boost" the low speed if necessary) |
OFF | 16 |
| 5 | Address Type | This setting switches the Address Type between 2-digit and 4-digit addressing. When this setting is enabled, the decoder will use a 4-digit "long" address. | OFF | 32 |
