Select the Bell
Each decoder version has a selection of bells at varying ring rates. Refer to the Sound
Selection Reference for the decoder to determine the correct values. Enter the desired value
into CV 122 and turn on the bell function (F1 by default) to ring the bell. Press the function key
again to stop the bell from ringing. Add a value of 128 to enable the grade-crossing bell.
Enabling the grade-crossing bell in CV 122 allows the bell to ring during the crossing hold timer
countdown after activating Grade-Crossing Logic with the airhorn function (F2 by default). For
more information about Grade-Crossing Logic, refer to “Configuring Lighting Outputs.”
Select the Air Compressor
Enter a value from 0 to 3 into CV 124 (Air
Compressor Select) to select your desired air
compressor. The air compressor plays
automatically during operation.
Select the Coupler
Enter a value from 0 to 2 into CV 126 (Coupler
Select) to select your desired coupler. Activate the
coupler selected in CV 126 with the couple (F13 by
default) and uncouple (F13 by default). Add a
value of 128 to invert the uncouple function
polarity. Inverting the uncouple function polarity
allows the uncouple sound effect to be activated
when you turn off the uncouple function.
The uncouple function polarity must be inverted in CV 126 in order to activate the uncouple
sound effect by turning off the uncouple function. For example, when the couple and uncouple
functions are mapped to the same function key and the uncouple function polarity is inverted in
CV 126, turning on the couple function with the function key will activate the couple sound
effect, and turning off the uncouple function with the function key will activate the uncouple
sound effect. If the couple and uncouple functions are not mapped to the same function key and
the uncouple function polarity is not inverted in CV 126, turning on the couple function will
activate the couple sound effect, and turning on the uncouple function will activate the uncouple
sound effect. To map effects to function keys F0-F28, Refer to “Configuring Function Mapping.”
Customizing the Traction Motor Sounds
CV 114 (Engine Exhaust Control) is used to customize traction motor sound effects to fit your
operating preferences.
CV 114: Adjust Auto-Notching Sensitivity
Add a value from 1 to 15 to CV 114 to adjust the
number of speed steps within each traction motor
notch from 1 to 15. Auto-notching is set to 4 speed
steps by default.
CV 114: Enable Engine Interlock
Add a value of 16 to CV 114 to enable engine interlock. When engine interlock is enabled, you
must turn on the Pantograph Extend, Retract function to energize the system before setting the
locomotive into motion. Similarly, you will be unable to de-energize the system during
movement. In other words, the locomotive must be stopped before you extend or retract the
pantograph. Engine interlock is disabled by default.
CV 124: Air Compressor Select
0 = Air compressor 1
1 = Air compressor 2
2 = Air compressor 3
3 = Air compressor 4
CV 126: Coupler Select
0 = Medium coupler (default)
1 = Heavy coupler
2 = Link-and-pin coupler
Inverted Uncouple Polarity:
CV 126 + 128
Auto-Notching Sensitivity
CV 114 + 0 = Auto-notching disabled
CV 114 + 1 = 1 speed step
CV 114 + 2 = 2 speed steps
↓
CV 114 + 15 = 15 speed steps
