When an output is controlled by more than one function key, either function
key will turn on that output. However, the output will not turn off until both
function keys have also been turned off.
To determine the correct CV value for customizing function mapping:
1. Locate the column in Table D that corresponds to the output or sound
effect you wish to control.
2. Next, locate the row that corresponds to the function key you would
like to use to control the selected output or effect.
3. Note the number located in the box at the intersection of the row and
column you have selected.
4. Program the CV in the row selected in Step 2 with the value located
in Step 3.
Example: Swapping the Bell and Short Horn Functions
Some DCC systems label F3 on their cabs as the bell control, however, the
SoundCar’s default bell control is F1. Fortunately, if you happen to have a
cab with F3 labeled as bell control, you can use function mapping to reassign
the control so that the function label controls that utility in the decoder. Since
F3 controls the short horn function by default in the SoundCar, we will simply
swap it with F1 as follows:
1. First, reassign F3 to the bell. In Table D, locate the bell column.
Then locate the F3 row. Note the value, 1, found in the box at the
intersection of the bell column and F3 row. Now, program a value of 1
into CV 37, which controls F3. F3 should now control the bell sound
effect.
2. Next, reassign F1 to the short horn following the same procedure.
Locate the short horn column in Table D, and then locate the F1 row.
Note the value, 128, found in the box at the intersection of the short
horn column and F1 row. Program a value of 128 into CV 35, which
controls F1. Now, F1 should control the short horn sound effect.
Working With 8-Function Cabs
While the SoundCar can support 14 functions, some cabs are limited to
only 8 or 9 functions, which may leave you feeling like you can’t take full
advantage of the DSD’s features. In most cases, some clever function
mapping will allow you to access and use all of SoundCar’s available
features.
Instant Function Swapping
Entering a value of 4 into CV 30 (Error Information/Alternate Mode Selection)
will swap function assignments for F5‑F8 with the function assignments for
F9‑F12. Think of CV 30 as a sort of “shift” key when bit 2 is enabled:
F5 = Generator
F6 = Uncoupling and Glad Hand Release
F7 = Apply/Release Brakes
F8 = Coupler Clank
Basic Programming
F9 = FX5 Function Output
F10 = FX6 Function Output
F11 = Dimmer
F12 = Audio Mute
