Configurations Supported
Range of Values0-255
Default ValueDEFAULT VALUE
Feature Description Default Value
Direction This setting controls the locomotive's forward and backward direction in digital mode only. Direction-sensitive functions, such as the motor and directional lighting headlights will be reversed so that they line up with the locomotive’s new forward direction. This setting offers a software-level fix if the decoder has been wired backwards, instead of re-wiring the engine. OFF 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
Analogue (DC) Operation If this setting is enabled, the decoder will operate when DC power is applied. The functionality of your decoder is based on your DC Mode Settings. OFF 4
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 OFF 8
User-Loadable Speed Tables This setting switches motor control between the 3-point Speed Curve and the 128-point Speed Curve. OFF 16
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
