2.3 Binding Procedure

The Archer M+ utilizes the FrSky ACCESS protocol. The binding process typically involves putting your FrSky ACCESS transmitter into bind mode and then powering on the receiver while holding its bind button (if applicable) or initiating OTA binding via the transmitter. Consult your specific FrSky transmitter manual for detailed ACCESS binding instructions.

3. Operating

3.1 ACCESS Protocol

The Archer M+ operates on the FrSky ACCESS protocol, which provides enhanced security, lower latency, and improved performance for your RC system. Ensure your FrSky transmitter is also running ACCESS firmware for full compatibility and feature utilization.

3.2 Telemetry Functionality

With its S.Port/F.Port, the Archer M+ supports telemetry, allowing you to receive real-time data from your model back to your transmitter. This includes information such as receiver voltage, signal strength (RSSI), and other sensor data if connected. The telemetry range is approximately 500 to 600 meters. Audio feedback can be configured on your FrSky ACCESS enabled transmitter to vocalize telemetry data.

3.3 Channel Output

The receiver provides 16 SBUS channels, with future support planned for 24 SBUS channels. This allows for extensive control over various functions of your RC model.

4. Maintenance

4.1 Firmware Updates (OTA)

The Archer M+ supports Over-The-Air (OTA) firmware updates. This feature allows you to update the receiver's firmware wirelessly through your FrSky ACCESS transmitter, eliminating the need for physical connection cables. Regularly check the official FrSky website for the latest firmware versions to ensure optimal performance and access to new features.

4.2 General Care

• Keep the receiver clean and free from dust, dirt, and moisture.
• Avoid exposing the receiver to extreme temperatures or direct sunlight for prolonged periods.
