Connection of sound module in Mix mode
Connection of motors
In the Mix mode, the driving speed is determined by the motor voltage. One or two
DC motors can be connected to the terminals X1/3 and X1/4 or X1/5 and X1/6. The
connection to the sound module is implemented parallel to the existing connections
of the speed controllers which powers the motors.
However, the sound module does not control the motor here - it only measures the
voltage on the motor. The voltage at the input may not exceed 15 V. A voltage
divider is necessary for higher voltages.
You only need to pay attention to the polarity of the motor connections if the output is
to be used for the reversing light or the reversing sound. If the reversing light lights
up when driving forward, the two connections must be swapped.
Connection of proportional channels
Up to 7 proportional outputs of an RC receiver can be attached to connectors X2/2 -
X2/8. Just use the two supplied servo patch cables for the connection. If more than
two proportional channels should be connected, further servo patch cables are
required. These can be ordered from us in our online shop in two lengths (15 cm and
30 cm).
A label on the cover of the sound module indicates the locations of the 8 channels.
Please attach the servo patch cables to the sound module with the brown wire face
the board edge and the orange wire to the board middle!
Following functions can be triggered with the 8 proportional channels on the sound
module:
Channel
Assignment
#1
Can be used for "direct control" (volume or servos)
#2
Steering / Free assignment of functions
#3
Free assignment of functions / Nautic 1 / EKMFA / Control Pad 1
#4
Free assignment of functions / Nautic 2 / Control Pad 2
#5
Free assignment of functions
#6
Free assignment of functions / Bluetooth module BTC-1
#7
Free assignment of functions
#8
Free assignment of functions / Sum signal
#9 - #16
Free assignment of functions (can only be used with a sum signal)
The channel numbers of the sound module have nothing to do with the channel
numbers of your receiver. So you do not have to connect channel #1 of the receiver
with channel #1 of the sound module.
