A：R12DS 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 RED led on R12DS 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 RED led will flash quickly, meaning binding process is ongoing.

4. When the RED 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：R12DS supports SBUS and PWM signals synchronously.

Receiver indicator is RED with all 11 channels output PWM signal.

Receiver indicator is Blue (Purple) with 12 channels output in total and synchronously output SBUS and PWM signal.

S-BUS signal channel (marked in BLUE) outputs 12 channels of S-BUS signal while PWM signal channels (CH3 to CH12 marked in BLUE) output PWM signals with 12 channels in total. The actual channel quantity of PWM signal output depends on that of SBUS signal output used. E.g. If 4 channels are used for SBUS signal output then there are only 8 channels of PWM signal output left.

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： R12DS is capable of outputting 12 channels with synchronous SBUS and PWM signal output. If only PWM signal needed, there are only 11 channels. But the SBUS signal output channel can be connected with a PWM board and realize more than 11 channels of PWM signal output.

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 12 to work with R12DS, the 12-channel receiver.

Press Mode button to enter BASIC MENU => Rotate the dial to select SYSTEM and Enter => Set CH-SELECT as 12CH.

A：

1. Check if the antennas of transmitter and receiver is damaged or welded joint or if they are installed 90°as below

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：

1. R12DS connects PRM-01 as below.

2. R2DS connects PRM-03 and different RadioLink flight controllers as below

A: Please try to 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 the below picture shows. If there’s still no response, the receiver may get burnt and needs to be repaired.

A: You can troubleshoot by the following methods:

1. Check the LED indicator color of R12DS. Red LED represents PWM signal, while blue/purple LED represents SBUS signal. RadioLink flight controller support SBUS and PPM signal. If the receiver indicator is red, please the binding button twice quickly to change the LED from red to blue/purple, SBUS working mode.

2. Enter BASIC MENU--SYSTEM menu. Set CH-SELECT to 12CH.
