Radiolink 7CH receiver R7EH-S
R7EH-S, 2.4G 7 channels receiver, FHSS, use for Radiolink transmitter T4EU, T4EU-6,
T6EHP-E.
S-BUS, PPM and PWM signal is possible working at the same time.
How to match code with transmitter:
1. Place the transmitter and the receiver close to each other within 1 meters.
2. Turn on the transmitter, then give power to receiver.
3. Connect CH3(R8EH) to ESC.
4. There is a black button near the antenna, use a thin stick press the button two seconds and
release, receiver light start blinking, after about 8 times blinking, match code success when
receiver signal LED on!
S-BUS, PPM and PPM signal change：
Short press the ID SET switch two times within 1 second, the signal is changed from normal
PWM to S-BUS or PPM. The green LED indicates the normal PWM and red&green LED
indicates S-BUS or PPM signal.
Fail safe:
Receiver will output signal:throttle zero, other channels keep the last signal from transmitter when
receiver can't receive signal from transmitter within 1 second.
SPEC.:
1. Channel: 7CH
2. Max input voltage: 6V
