A：R9DS is compatible with RadioLink AT9/AT9S/AT9S Pro/AT10/AT10II.

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 R9DS will be on.

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

A：R9DS supports SBUS and PWM signals synchronously.

Receiver indicator is RED with all 9 channels output PWM signal.

Receiver indicator is Blue (Purple) with 10 channels output in total and synchronously output SBUS and PWM signal.

Ch9 outputs SBUS signal while Ch3 marked in BLUE outputs PWM signal and helicopter is adaptable. When Ch6 to Ch10 output PWM signal, there are 10 channels in total.

Short press the binding button (ID SET) twice within 1 second to switch the S-BUS&PWM signal to PWM signal.

A：R9DS is capable of outputting 10 channels with synchronous SBUS and PWM signal output. If only PWM signal needed, there are only 9 channels. But the SBUS signal output channel can be connected with a PWM board and realize more than 9 channels of PWM signal output.

A：

1. R9DS connects PRM-01 as below

2. R9DS connects PRM-03 and RadioLink flight controller MINI PIX/APM as below

Note: The wires to connect RadioLink PIXHAWK is different from TURBO PIX but the port remains the same as TELEMETRY on flight controller

A：

1. Check if the battery is charged.

2. Check if the polarity is correctly connected.

3. Check if connection between the receivers and the power supply is good.

If there’s no problem with the above three points, the receiver may get burnt and needs to be repaired.

A：First, check if the power supply of the receiver and the transmitter is ok.

Then modify the channel quantity of the transmitter (AT9/AT9S/AT10/AT10II) as 10 to work with R9DS, the 10-channel receiver.

Press Mode button to enter BASIC MENU => Rotate the dial to select SYSTEM and Enter => Set CH-SELECT as 10CH.

A：

1. Check if the antenna of transmitter and receiver is damaged or welded joint.

2. Check if there’s interference resources like electricity substation or high voltage cable or WIFI nearby.

3. Check the RSSI value.

① Power on the transmitter and receiver with both antennas parallel and straight and within the distance of 30cm.

② Then check the RSSI value. Range between 0~-30dBM is normal and if the value gets closer to 0, the signal is stronger.

A：Please try short circuit binding by metal. Remove the cover of the receiver and power it on, use a metal accessory to touch the silver pad on both sides of the binding button to do the binding or signal output switch as below picture shows. If there’s still no response, the receiver may get burnt and needs to be repaired.

A: When using different receivers, you need to set CH-SELECT on AT10II/AT9S Pro/AT10/AT9S/AT9. Select 10CH for R9DS/R6DS/R6DSM receiver and select 12CH for R12DS/R12DSE/R12DSM receiver. If the selection is wrong, the servos will shake violently and cannot work well.

Here is a tutorial of it for your reference:

A: Yes. You can bind them one by one. When binding one of the receiver, other receivers need to be powered off. After you have bound all the receivers to AT10II/AT9S Pro/AT10/AT9S/AT9, power on all the receivers, the transmitter can control all the receivers at the same time.

A: Could you please follow the below methods to troubleshoot the problem?

1.Check if you have turned on the RF-MODE on the transmitter. Enter Basic menu-PARAMETER--RF-MODE. Set RF-MODE to ON.

2.Then please follow the binding tutorial to bind the receiver to the transmitter:

3.You can replace another receiver to have a try to confirm if the problem comes from the receiver or the transmitter.

4.If the problem still exists, please send a binding tutorial to after_service@radiolink.com.cn to confirm the problem.

A: 1. Please test RSSI. Here is the tutorial of RSSI testing: https://www.youtube.com/watch?v=jr7ad-_MVoI

2.Check the antenna condition of the transmitter and the receiver.

3.Make sure the antenna is not near the metal or carbon fiber materials.

4.Please replace another receiver to have a try. It can help to confirm if the problem comes from the receiver or the transmitter.
