3. Setup Guide
3.1. Binding the R9DS Receiver
Follow these steps to bind your R9DS receiver with a compatible Radiolink transmitter:
- Place the transmitter and receiver close to each other, within 30-50 centimeters.
- Turn on the transmitter, then power on the R9DS receiver.
- Press the binding button on the R9DS receiver for 1 second and release. The LED indicator on the receiver will flash quickly during the binding process.
- For AT10II transmitters, ensure the SYSTEM channel selection is set to 10ch mode for proper operation.

3.2. Signal Output Modes (PWM/SBUS)
The R9DS receiver supports two signal output modes: PWM and SBUS. The mode is indicated by the color of the LED on the receiver.
- PWM (Red LED): Provides 9 channels of Pulse Width Modulation output.
- SBUS (Blue LED): Provides 10 channels of Serial Bus output.
To switch between modes, short press the binding button twice within one second. The LED color will change to indicate the active mode.
Image Description: This image illustrates the two signal output modes of the R9DS receiver. The top diagram shows PWM output with 9 channels, indicated by a red LED. The bottom diagram shows SBUS output with 10 channels, indicated by a blue LED, along with the corresponding wiring for each mode.
3.3. Voltage Telemetry Connection
To enable voltage telemetry and display your airplane's battery voltage on your transmitter screen, the R9DS receiver must be equipped with a telemetry module like the PRM-01 or PRM-03. Connect one end of the PRM-01 module to the telemetry port of the R9DS receiver, and the other end to the airplane's battery.
Image Description: This diagram details the connection for voltage telemetry. It shows the R9DS receiver, a PRM-01 Telemetry Module, an ESC (Electronic Speed Controller), and an airplane battery, illustrating how to wire them to display external battery voltage on the transmitter.
Video Description: This video demonstrates how to set up and view the telemetry data, specifically the airplane's battery voltage, directly on the screen of a Radiolink AT9S Pro transmitter using the R9DS receiver and a PRM-01 telemetry module.
4. Operation Instructions
4.1. Transmitter Channel Selection
When using the R9DS receiver with a 12-channel transmitter like the AT10II, it is crucial to set the transmitter's system channel selection to 10-channel mode. Failure to do so may result in improper functionality or unstable servo control.
Image Description: This image displays the system menu of Radiolink AT9S Pro and AT10/AT10II transmitters, highlighting the 'CH-SELECT' option. It instructs users to set this option to '10CH' to ensure proper compatibility and operation with the R9DS receiver.
Video Description: This video explains how to configure a Radiolink AT9S Pro transmitter to work correctly with a 12-channel receiver, demonstrating the necessary channel selection adjustments within the transmitter's system menu.

7. Care and Maintenance
- Keep the receiver dry and away from moisture.
- Avoid exposing the receiver to extreme temperatures or direct sunlight.
- Regularly inspect antenna connections for any damage or loose contacts.
- Clean the receiver gently with a soft, dry cloth if necessary. Do not use harsh chemicals.
- Ensure proper ventilation when installed in a model to prevent overheating.
8. Troubleshooting Tips
- No Signal/Binding Issues: Ensure the transmitter is powered on and the binding procedure is followed correctly (transmitter and receiver within 30-50cm). Check that the transmitter's RF mode is enabled and the channel selection matches the receiver (e.g., 10CH for R9DS).
- Unstable Servo Control: Verify that the transmitter's channel selection matches the receiver's capabilities. Incorrect channel settings can lead to erratic servo behavior.
- No Telemetry Data: Confirm that the PRM-01/PRM-03 telemetry module is correctly connected to both the R9DS receiver and the model's battery. Ensure the transmitter's firmware supports telemetry display.
- Reduced Range: Check for any obstructions or damage to the receiver's antenna. Ensure the antenna is positioned straight and away from carbon fiber or metal components.
- Receiver Not Powering On: Check the power supply to the receiver. The R9DS operates between 4.8-10V DC. Ensure correct polarity; the receiver has anti-polarity protection but always double-check connections.
