Product Features

             

R12DS, with 2.4G DSSS&FHSS spread spectrum technology, is a 12-channel receiver that SBUS and PWM can operate synchronously. With 4096 section precision, 0.25us per section and servo anti-shake rudder, it is compatible with RadioLink transmitters AT9, AT9S, AT10 and AT10II, all of which can be upgraded to 12 channels with the firmware that downloaded from www.radiolink.com.cn/doce/firmwaredownload.html . As R12DS is extended telemetry module PEM-01 and PRM-03 supported, pilots can read all flight information during RC fun.

Signal working modes:

There are two signal working modes, PWM and SBUS&PWM signal output. Short press the binding button(ID SET) twice within 1s, the working mode will change. The RED led indicates the PWM output and BLUE/PURPLE led indicates SBUS&PWM signal output. 

(1)PWM signal output working mode:red LED indicates PWM signal output, 11 channels totally.

(2) S-BUS&PWM signal output working mode: blue/purple LED indicates S-BUS signal output, 12 channels totally.  BLUE/PURPLE led indicates SBUS&PWM signal output at the same time with 12 channels totally. S-BUS signal channel(3 pin of row 11) output 12 channels of S-BUS signal while PWM signal channels(3 pin of row 1 to row 10, i.e CH3 to CH12) output PWM signals with 12 channel in total. The actual channel quantitly of PWM signal output depends on that of SBUS signal output used. Eg. If 4 channels of SBUS signal output used, then there are only 8 channels of PWM signal output left.

How many PWM signal channels you can use depends on how many S-BUS signal channels you have used(e.g: you have use 4 S-BUS signal channels, then you have 8 PWM signal channels to use).

Note

If working with AT9S or AT10II, the channel mode should be set as 12-CHANNEL.

Binding

1. Place the transmitter and the receiver close to each other within 50 centimeter.


2. Powe on the transmitter and R12DS, the RED led will be on.


3. Turn on AT10II and it will automatically bind to the closest receiver. 

4. There is a black binding button(ID SET) on the side of R12DS. Press the button for more than one second and release, the RED (by default, could be Purple for SBUS&PWM siganl output) led will flash, meaning binding process is ongoing.

5. When the led stops flashing and is always on, binding is complete.

6. Make sure servos connected with the receiver can be operated by the transmitter.

 

Installment of receiver antenna

1. Keep the antenna as straight as possible and 90°as below, or the effective control range will reduce.

2.Big models may contain metal parts that influence signal emission. In this case, antenna should be positioned at both sides of the model to ensure the best signal status in all circumstances.

3.The antennas must be kept away from metal conductor and carbon fiber at least at least 2cm(0.5 inch) away and no over bending. 

4.Keep antennas away from the motor, ESC, and other possible interference sources.

Note Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration and high temperature.

When all the above steps are complete, please turn off the transmitter and repower on to test if the receiver is correctly connected with it.
