A: R12F supports SBUS, PWM, and CRSF signals output synchronously.

PWM working mode: Red LED always on indicates PWM signal output, 12 channels total.

PWM+SBUS working mode: Blue and red LED always on indicates PWM+SBUS signals output.

CH1 to CH11 are with PWM signal output while CH12 with SBUS signal output.

Users can personalize signal output mode to fully enjoy the fun of a model bait boat or car with FPV.

PWM+CRSF+SBUS working mode: Blue, green, and red LEDs always on indicate PWM+CRSF+SBUS signal output.

CH1 to CH9 outputs the PWM signal, CH10 to CH11 outputs the CRSF protocol, and CH12 outputs the SBUS signal.

A: R12F is compatible with RadioLink T series aircraft transmitters and all the surface transmitters.

T series aircraft transmitters: 16 fully-proportional channels transmitter T16D, 12 fully-proportional channels transmitter T12D, 8 channels transmitter T8FB(BT), T8S(BT), T8FB(OTG), and T8S(OTG).

All the surface transmitters: 8 channels transmitter RC8X, 7 channels transmitter RC6GS V3, 5 channels transmitter RC4GS V3, 6 channels transmitter RC6GS V2, RC6GS, and 4 channels transmitter RC4GS V2, RC4GS.

A:

1. Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.

2. Switch on the transmitter and the LED of R12F will start flashing slowly.

3. There is a black binding button (ID SET) on the side of the receiver. Press the button for more than 1 second and release, the LED will flash quickly, meaning the binding process is ongoing.

4. When the LED stops flashing and is always on, binding is complete and there will be a signal tower shown on top of the transmitter's screen.

Note: If bound to transmitters without a screen like T8S or T8FB, the always-on LED means the binding is completed.

A: The slow flashing LED means binding doesn’t succeed or the signal gets lost after binding completes.

A: The operating voltage range of R12F is from 3V to 12V.
