SWITCH ASSIGNMENT TABLE

• The factory default functions activated by the switches and knobs for a AT9S Pro transmitter are shown below.

• Most AT9S Pro functions may be reassigned to non-default positions quickly and easily. Always check that you have the desired switch assignment for each function during set up.

Compatible Receivers

AT9S Pro is a 12 channels transmitter, support 2.4G DSSS and FHSS dual hybrid spread spectrum, 16 channels pseudo random frequency hopping.

AT9S Pro sells with receiver R9DS.

R9DS is a 9 channels receiver when working with PWM signal(red LED), it will a 10 channels receiver when working with S-BUS signal(purple/blue LED).

Besides R9DS, AT9S Pro is also compatible with Radiolink R6DS, R10DS, R12DS and super mini 10 channels receiver R6DSM and 12 channels mini dual antenna receiver R12DSM.

R6DS, is a 6 channels receiver when working with PWM signal while it is a 10 channels receiver when working with SBUS or PPM signal.

R12DS, is a 11 channels receiver when working with PWM signal while it is a 12 channels receiver when working with SBUS signal.

Note AT9S Pro is default 10 channels, you can upgrade it to 12 channels with USB cable. You have to setup AT9S Pro to 12 channels first if you use 12 channels receivers R12DS or R12DSM while you have to setup AT9S Pro back to 10 channels when you use 10 channels receiver R6DS, R6DSM and R10DS.

To setup to 12 channels: power on your AT9S Pro--Press Mode button one second into BASIC MENU--into SYSTEM menu--change CH-SELECT from 10CH to 12CH.

Since Radiolink radio control systems are not open source, that Radiolink transmitters just compatible with Radiolink receivers and vice versa.

Connect to TBS Crossfire TX

• Power on the transmitter- Long press the Mode key to enter the BASIC MENU->Rotate the Scroll Dial to highlight the SYSTEM option and depress the Enter key->Select the OUT and change the output as CRSF

Note There are totally three signal output SBUS/PPM/CRSF

• Connect the TBS Crossfire transmitter to the AT9S Pro with the cable(packed inside the box)

The detailed steps please refer to the video tutorial https://youtu.be/g_mfHdeEQCo

Note The compatibility function with TBS Crossfire TX is only available in AT9S Pro, which CANNOT be upgraded from AT9S Pro directly.

RSSI testing

Power on transmitter and receiver, keep transmitter apart from receiver about 30 centimeters and both antennas straight.

Enter the parameter setup menu by press MODE one second, you can check the RSSI in RECEIVE.

The RSSI is 0 to 30dBm is normal when the transmitter is apart about 30 centimeters from the receiver, the signal is more better the RSSI data is more close to 0.

Radio Installation

Mount the Servos, Receiver and Battery

• Make certain the alignment tab on the battery, switch and servo connectors is orient correctly and ‘key’ into the corresponding notch in the receiver or connectors before plugging them in .When unplugging connectors, never pull on the wires. Always pull on the plastic connector instead.

• Receiver’s Antenna: In generally receiver’s antenna is longer than remote control, don’t break or retract it, otherwise shorten the control distance. The antenna must be kept away from conductive materials, such as metal. Please make distance test before flying.

• If your aileron servos are too far away to plug into the receiver, use an aileron extension cord to extend the length. Avoid plugging multiple extensions together to obtain your desired length. If the distance is greater than 50cm or high current draw servos are being used, use heavy servo extensions.

• Receiver Vibration and Waterproofing: the receiver contains precision electronic part. Be sure to avoid vibration, shock, and temperature extremes. For protection, wrap the receiver in foam rubber or other vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag and securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver, you may experience intermittent operation or a crash. If in doubt, please contact Radiolink aftercares or distributors for service.

• Always mount the servos with the supplied rubber grommets. Don’t over tighten the screws. No part of the servo casing should contact the mounting rails, servo tray or any part of structure. Otherwise vibration will be transmitted to the servo causing damage of servo. Note the small numbers (1, 2, 3, and 4) molded into each arm on the servo arms. The number indicate how many degrees each arm is ‘off’ from 90 degrees to correct for minute manufacturing deviations from servo to servo.

• To center the servos, connect them to receiver and turn on the transmitter and receiver. Center the trims on the transmitter, then find the arm that will be perpendicular to the pushrod when placed on the servo.

•After the servos are installed, operate each servo over its full travel and check that the pushrods and servo arms don’t bind or contact each other. Also make sure the controls do not require excess force to operate. If there is an objectionable buzzing sound coming from a servo, there is probably too much resistance in the control. Find and correct the problem. Even is there is no servo damage, excess battery drain will result.

• Use the mounting plate from the receiver on/off switch as a template for the cutout and screw holes, mount the switch on the side of the fuselage opposite the engine exhaust, and where it won’t be inadvertently turned on or off during handling or storage. Be certain the switch moves without restriction and ‘snaps’ from ON to OFF, and that the cutout allows full motion of the switch in both directions.

• When install the switch harness to the helicopter please use the switch cover. Generally sandwich the frame between the switch and switch cover and securely tighten the screws, Different models might require different installations. If so, please follow the model’s instruction manual.

• To prevent the servo lead wires from being broken by vibration during flight, provide a slight amount of slack or extra so that the wire sticks out slightly and fasten it at suitable points. In addition, periodically check the wire during daily maintenance.
