Connection of the sound module in digital operation
Connection of the proportional channels
At connectors X1/1 - X1/4 up to 4 proportional outputs of an RC receiver can be
connected. You use the 2 supplied servo patch cables for the connection. If more
than 2 proportional channels should be connected, further servo patch cables are
needed, which you can order in our shop.
There is a labeling that characterizes where the 4 channels on the board are. The
channels #1 and #2 are carried out twice, so the proportional signal keeps on being
able to be continued directly to the speed controller or servo. If further speed
controllers or servos should be connected to the channels #3 and #4, Y-cables are
needed.
To put on the servo patch cables onto the sound module, be sure that the brown wire
points to the board edge (to the right), the orange wire to the board middle (to the
left).
With the 4 proportional channels following functions on the sound module can be
triggered:
Channel Model with 1 motor Model with 2 drive motor
#1 speed-dependent
driving noise
speed-dependent
driving noise
#2 additional sounds 9-12
light, indicators, hazard warning
light
speed-dependent
driving noise
#3 additional sounds 1-4 additional sounds 1-4
#4 additional sounds 5-8
driving sound on/off
volume control
additional sounds 5-8
driving sound on/off
volume control
If you have a model with 2 motors (e.g. chain vehicle) and use the proportional
channel #2 for the driving speed identification, unfortunately you can’t activate the
additional sounds 9-12 with this proportional channel. In the same way, no outputs
for light, indicators and hazard warning light can be switched then.
Connection of the switching-inputs
At the terminals X1/7 - X1/10, the additional sounds 13-16 can be triggered. To
activate a sound, the negative pole of the supply voltage must be switched to the
respective input. Normally switch modules are used for this (as our RC-SM-2 or other
standard multi-switch-modules). Because these switch modules are all negativ-
switched, only the outputs of the switch module must be connected to the inputs of
the sound module.
