Basic Programming
Then configure F3 to control the Water Stop Sound:
Set CV 37 = 64
Next, we configure F5 and F6 to control the Brake Squeal and Coupler
respectively. But wait! Looking at Table F, it appears that this can’t be done.
The trick is to use the Instant Function Swapping feature so Function 5 now
controls the output assigned to Function 9, Function 6 now controls the
output of Function 10, and so forth.
To activate Function Swapping, set CV 30 to 4. Once this is done, the control
CVs for a particular function also get swapped so that the function mapping
CVs are assigned as follows:
Function 5 is now mapped with CV 43
Function 6 is now mapped with CV 44
Function 7 is now mapped with CV 45
Function 8 is now mapped with CV 46
Function 9 is now mapped with CV 39
Function 10 is now mapped with CV 40
Function 11 is now mapped with CV 41
Function 12 is now mapped with CV 42
Now use Table F to remap F5 to control the Brake Squeal:
Set CV 43 = 128
Then map F6 to control the coupler:
Set CV 44 = 128
We would like to keep the original function assignments for F7 (dimmer)
and F8 (mute). By turning on the Function Swapping feature, however, the
outputs for these functions are now mapped through CV 45 and 46 which,
by default, are set to control some other output. It is necessary to reprogram
these CVs as well to get the desired functionality:
Re-map F7 to control the dimmer:
Set CV 45 = 8
Re-map F8 to control the mute:
Set CV 45 = 16
Finally, we must activate the automatic whistle signals by setting CV 198 to 2.
The injectors are already part of Fireman Fred’s repertoire so there is nothing
else needing change.
