R9DS Receiver

Working Modes
R9DS, with 2.4G DSSS&FHSS spread spectrum technology, is a 9-channel receiver when working with PWM signal output (red LED) or a 10-channel receiver when withSBUS&PWMsignal output (purple/blue LED)

PWM Signal Molded red LED indicates PWM signal output, 9 channels totally

Note : PRM-01 and PRM-03 telemetry modules are sold separately.
SBUS &PWM Signal Mode: Blue/purple LED indicates SBUS&PWMsignal output thesametimeto with 10 channels totally. CH9 outputs SBUS signal while the origina1outputsCH3PWM signal and original CH2 to CH6 output CH6 to CH10 PWM signal at the sometime

Note : Fixed wing equipped with flight controller is taken as an example

Switch Signal Mode Short press binding button (ID SET) twice within 1 second, theworkingmode will be switched.

Channel Settings
AT9S Pro is a 12-channel transmitter, but the channel is selected as 10 channels by default (See the right picture). When using the standard packed R9DS receiver, there is no need to modify the settings; but when using R12DS or R12DSM receiver, channel of AT9S Pro should be selected as 12channel, 12CH. For the channel selection of AT9S Pro when using different receivers, please refer to the figure below:

Receiver Model	AT9S Pro CH-SELECT
R9DS	10CH
R6DS	10CH
R6DSM	10CH
R12DS	12CH
R12DSM	12CH

Setting steps: BASIC menu – SYSTEM – CH-SELECT.
Note : If the channel of AT9S Pro is selected incorrectly, the servo may vibrate all the time.

Binding
AT9S Pro and R9DS have already finished binding by default. Turn on AT9SProandR9DS,thesignal tower will be displayed on the top of the screen (See the right picture), which means AT9S Pro and receiver have finished binding. If you purchase a new R9DS receiver separately, you need to bind the receiver to the transmitter. Each receiver has an individual ID code. When the binding is done, the ID code will be stored in the transmitter andthere’snoneedto rebind.
Binding

Binding Steps:

Put the transmitter and the receiver close to each other (about 30 centimeters).
Power on AT9S Pro and R9DS, the LED of R9DS will be on.
There is a black binding button (ID SET) on the side of receiver. Press the button for morethanone second and release, the RED (by default, could be Purple for SBUS&PWMsignal output)LED will flash, meaning binding process is ongoing.
When the LED stops flashing and is always on, binding is complete. There will beasignaltower shown on top of the LCD screen of the transmitter. If not succeed, theLEDwill keep lashing slowly to notify, repeat the above steps.
Note Since Radio Link radio control systems are not open sourced, Radio Link transmittersareONLY compatible with Radio Link receivers. After connecting TBS Crossfire moduletoAT9SPro,the connection to TBS Crossfire receiver

Installment of Antenna

Receiver Antenna Installment

Please test RSSI (Received Signal Strength Indicator) before operating models. For methods on how to test it, please refer to https://www.radiolink.com/newsinfo/477894.html.
If the antenna of the receiver is damaged, replace it with a new antenna or receiver in time.
Keep antennas as straight as possible, or the effective control range will reduce.
Big models may contain metal parts that influence signal emission. In this case, antenna should be positioned at one side of the model to ensure the best signal status in all circumstances.
Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no over bending.
Keep antennas away from motor, ESC, or other possible interference sources.
Receiver contains some electronic components of high-precision. Be careful toavoidstrongvibration and high temperature

Transmitter Antenna Orientation

The transmitter antenna orientation is adjustable. Please make sure that theantennaneverpoints directly at the model when flying as this may possibly decrease the receiver signal.(See Picture 1 below).
If the antenna is upright, the antenna signal mainly diverges in the horizontal direction, which is beneficial to flying farther (See Picture 2 below); if the antenna is horizontal antiparallel to the ground, the signal mainly diverges in the vertical direction, whichisbeneficialto fly higher (See Picture 3 below), so it is best to place the transmitter antenna perpendicular to the connection line between the remote control and the aircraft during flight.
During the flight, please ensure that there is no obstruction between the transmitter antenna and the receiver antenna to maximize the communication distance.

RSSI Testing
RSSI stands for Received Signal Strength Indicator. Before flight, always remember todotheRSSI testing to avoid the possible unexpected signal loss

Power on transmitter and receiver, keep them with the distance of about 30 centimeters and both antennas straight (See the right picture).
Enter the basic menu. Rotate the PUSH button to select RECEIVE and press PUSH button to enter and check the RSSI value. RSSI valuebetween0to-30dBm is normal when the transmitter keeps about 30 centimeters distance fromthereceiver.The RSSI value is closer to 0, the signal is stronger

Real-time Built-in Telemetry
R9DS receiver integrates telemetry of signal strength and receiver voltage by default. It canals realize the telemetry of model battery voltage or flight controller and GPS informationwhenusedwith Radio Link PRM-01 or PRM-03 telemetry module, and the telemetry informationcanbedisplayed on the screen of AT9S Pro or AT10II

Model battery voltage telemetry: When connecting R9DS to telemetry modulePRM-01,themodel voltage will be displayed on the screen of AT9S Pro (See picture below). Note: PRM-01 is sold separately. PRM-01 only supports R9DS or R12DS receiver.

Flight controller and GPS information telemetry : When connecting R9DStotelemetrymodule PRM-03 and flight controller, more information will be displayed on the screen of AT9SPro, including the model battery voltage, speed, climb, throttle, longitude, latitude, altitude, GPS,RSSI, flight mode, yaw, roll, pitch, and distance (See picture below)
Note : PRM-03 is sold separately. PRM-03 only supports R9DS or R12DS receiver, bandit works with flight controller crossflight, PIXHAWK, Mini Pix, TURBO Pixy or APM.
GPS information
