Control of servo output 1 on a IR light module
For models no. 1 - 3 (trucks) it is also possible to control servo output 1 of the light
modules LM-IR-8-1 and LM-IR-16-4 via IR transmission. For example, trailer support
legs can be controlled via a speed controller that is connected to servo output 1.
However, the control of the IR servo output must first be temporarily activated using
the “IR servo” function. This is done by placing Prop #4 in the “D” area for longer than
2 seconds. The hazard warning lights flash quickly to indicate that the IR servo
control is active.
Now servo output 1 can be controlled proportionally via Prop #2 (steering channel).
However, if a steering servo is connected to Prop #2, the steering servo will also
move with it! Control of the IR servo output is only possible when the model is
stationary, i.e. the gas channel is in neutral position.
To deactivate the IR servo control again, Prop #4 must be brought into the “D” area
again for longer than 2 seconds. The servo output on the IR light module then goes
to neutral (center). The hazard lights stop flashing quickly and Prop #2 goes back to
just controlling the steering servo and the turn signals.
Status display with LEDs
There are 3 LEDs on the sound module that show the status or the different states of
the sound module.
As soon as the MSM-1 is connected to the power supply (X1/1 and X1/2), the green
LED lights up.
During model selection (setup), the 3 LEDs indicate the selected model type. See
page 6.
