Product Features


Radiolink R9DS, 2.4G 9 channels receiver, DSSS and FHSS spread spectrum working

synchronously, use for Radiolink transmitters AT9S, AT9, AT10II and AT10.

SBUS and PWM signal possible working at the same time.




Two signal working mode:


(1) PWM signal output working mode:red LED indicates PWM signal output, 9 channels totally.


(2) SBUS signal output working mode: blue/purple LED indicates SBUS signal output, 10 channels


SBUS and PWM signal possible working at the same time with SBUS signal output working mode.

CH9 output SBUS signal, the original CH1 output CH3 and original CH2 to CH6 output CH6 to CH10

 PWM signal at the same time. 



SBUS and PWM signal change:

SBUS and PWM signal change:

Short press the ID SET switch twice within 1 second, the signal is changed from normal

PWM to SBUS. The red LED indicates the normal PWM and blue/purple LED indicates

SBUS signal.



How to match code with transmitter:

1. Place the transmitter and the receiver close to each other within 1 meter.

2. Turn on the transmitter, then power on the R9DS.

3. Connect CH3 of R9DS to ESC or flight controller or servo.

4. There is a black button on the R9DS, use a thin stick or pen press the binding button in

one second until the receiver light starts blinking and release, after about 8 times blinking,

match code success when receiver signal LED always on.


Installment of receiver antenna:

1. The antenna must be kept as straight as possible. Otherwise it will reduce the effective


2. Large model aircraft may of some metal part interfering signal; in this case the antennas

should be placed at both sides of the model. Then the best RF signal condition is obtained at any

flying attitude. 

3. The antennas must be kept away from conductive materials, such as metal and carbon by at

least a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do

not bend it in a small radius.

4. Keep the antennas away from the motor, ESC, and other noise sources as much as possible.

5. The receiver can be packed by sponge or foam for shocking proof when it is installed to the


After all of the above steps finished, now the program functions to assure it under control of

transmitter with a right connection.


Technical Parameters




 1) Channels: 

    9 channels: output 9 channels PWM signal, with red LED.

   10 channels: output 10 channels signal, support SBUS and PWM signal output

synchronously, with blue LED.

 2) Working voltage: 4.8-10V

 3) Working current: 38-45mA(input voltage: 5V)

 4) Size: 43*24*15mm

 5) Receiver integrate telemetry sensor including signal strength and voltage. Support

extended engine voltage telemetry module PRM-01 and module PRM-02 can feedback

GPS info, Speed, voltage etc. on AT9/AT9S/AT10/AT10II display when work with flight

controller APM, PIX or MINI PIX.

 6) 4096 section precision, 0.25us per section, servo anti-shake rudder.

 7) MINI receiver, just need one cable if use SBUS signal.
