D Sound module USM-RC-2

Servo outputs
The USM-RC-2 offers 2 servo outputs (X8/1 and X8/2). These 2 servo outputs share
their function with the switching-outputs 11 and 12. If servo 1 is activated in the
Sound-Teacher, the function of the switching-output 11 is deactivated. There
shouldn’t be anything connected to switching-output 11 if servo 1 is activated! If you
really want to use switching-output 11, you must disable servo output 1 and
disconnect any connections to it.
The same is valid for the servo output 2 and the switching-output 12.
The servo outputs deliver usual pulses from 1,000 - 2,000ms, so you can connect
standard servos or speed-controllers.
The power for the servo outputs is supplied from the proportional inputs #1 - #4 using
the connections X2/1 - X2-4. Generally these connections are attached directly to the
receiver, so the receiver battery and the BEC in the speed-controller must deliver
enough current for the servos!
For every servo output, up to 5 positions can be defined in the Sound-Teacher (see
page 62). The freely assigned functions of the sound module are used to move the
servo into a defined position. The positions have the following names:
• Home position
• Position #1
• Position #2
• Position #3
• Position #4
The servo movement can also trigger a sound. The additional sounds “Sound from
servo 1/2“are responsible for this. It also distinguishes between left and right
movement. So you can play for every direction of running a different sound.
If you don’t want sounds while moving the servos, just leave these sound-slots
empty.
