3D Robotics PPM Encoder User Manual

PPM ENCODER

PPM encoder module

Translates up to eight PWM (pulse width modulation)
signals into one PPM (pulse position modulation) signal,
allowing you to connect a PWM receiver to a PPM­compatible autopilot over one wire

Three-wire cable (12 cm)

DF13 three-position to servo cable connects
the encoder to the autopilot

Ten-wire cable (7 cm)

DF13 ten-position to servo cable connects
the PWM receiver to the encoder

Connect a PPM receiver

Connect the ten-wire cable to

1

the encoder’s ten-position port.

Connect each wire to your RC receiver. Connect

2

the red wire to power, the black wire to ground,
and the white wires to channels one through
eight as shown below.
