Flex-Map Function Mapping Examples
The following examples detail using CVs 1.257-1.512 for function mapping, enabling automatic
effects, and mapping an effect to the emergency stop button. Before accessing CVs 257-512,
ensure CV 31 is set to a value of 16, and enter a value of 1 into CV 32.
Example: Mapping Electric Functions
You may want to use CVs 1.257-1.384 to map the grade-crossing signal to F4, stop request bell
to F10, and trolley bell to F9. Doing so will allow you to activate airhorn functions with F2, F3,
and F4 and bell functions with F9 and F10. The following example details mapping the grade-
crossing signal (F9 by default), pantograph extend, retract (F4 by default), and trolley bell (F10
by default) functions with CV 1.278 (Grade-Crossing Signal Map Register), CV 1.301
(Pantograph Map Register), and CV 1.315 (Trolley Bell Map Register):
1. To map the grade-crossing signal next to the long airhorn (F2 by default) and short
airhorn (F3 by default), enter a value of 4 into CV 278.
2. To map the dynamic brake next to the independent/train brake (F11 by default), enter a
value of 10 into CV 299.
3. To map the straight-to-eight function to F9, enter a value of 9 into CV 301.
4. Activate airhorn functions with F2, F3, and F4.
5. Activate brake functions F11, and F12.
6. Activate straight-to-eight with F9.
Example: Setting Up Automatic Signals
You may want to use CVs 1.384-1.512 to enable automatic forward, reverse, and stop whistle
signals. The following example details setting CV 1.407 (Forward Whistle Signal Auxiliary Map
Register), CV 1.408 (Reverse Whistle Signal Auxiliary Map Register), and CV 1.409 (Stop
Whistle Signal Auxiliary Map Register) to enable automatic whistle signals:
1. Enter a value of 1 into CV 407 to enable automatic forward signals when the locomotive
is forward-driving.
2. Enter a value of 2 into CV 408 to enable automatic reverse signals when the locomotive
is reverse-driving.
3. Enter a value of 12 into CV 409 to enable automatic stop signals when the locomotive is
standing (regardless of direction).
Example: Mapping the Emergency Gyralite to the Emergency Stop Button
You may want to map the emergency Gyralite to add a lighting effect to the emergency brake
application effect. The following example details setting the emergency Gyralite to the FX3
lighting output, and mapping the FX3 effect to the emergency stop button:
1. Enter a value of 21 into CV 51 (FX3 Configuration) to set the emergency Gyralite to the
FX3 lighting output. Refer to “Configuring Lighting Outputs” for more information.
2. Enter a value of 255 into CV 259 (FX3 Effect Map Register) to disable function control
for the FX3 lighting output.
3. To map the emergency Gyralite to the emergency stop button, enter a value of 16 into
CV 387 (FX3 Effect Auxiliary Map Register).
