3.3 Binding Process

1. Power on your Radiolink transmitter and navigate to the binding menu.
2. Connect the R12DSE receiver to a power source (3-6V DC). Ensure correct polarity; the receiver has built-in protection against reverse polarity.
3. Manteniu premut el botó LLIGAR button on the R12DSE receiver.
4. The receiver's LED indicator will flash rapidly, indicating it is in binding mode.
5. Initiate the binding process on your transmitter.
6. Once successfully bound, the receiver's LED will turn solid red. The binding process typically takes approximately 1 second.

3.4 Signal Output Configuration (SBUS/PPM)

The R12DSE receiver supports both SBUS and PPM signal outputs. The receiver indicator LED is red by default. All twelve channels respond simultaneously within 3ms. This compatibility extends to almost all flight controllers, making it suitable for racing drones.

4. Funcionament

4.1 Real-time Built-in Telemetry

The R12DSE receiver includes a built-in data transmission function. Signal strength and receiver voltage information will be displayed directly on the main screen of compatible Radiolink transmitters (AT10II, AT10, AT9S Pro, AT9S, AT9). The RSSI value will also be displayed in the REBRE menu without requiring external sensors.

4.2 Advanced Telemetry with PRM-03 Module

When the R12DSE is paired with the optional Telemetry Module PRM-03 and a compatible flight controller (such as PIX6, PIXHAWK, CrossRace Pro, CrossRace, CrossFlight, Mini Pix, APM, TURBO PiX), a wider range of telemetry data becomes available. This includes model voltage, speed, rise, throttle, longitude, latitude, altitude, GPS coordinates, RSSI, flight mode, yaw, roll, pitch, and distance. This information will be displayed on the REBRE menu of your AT10II, AT10, AT9S Pro, AT9S, or AT9 transmitter.

5. Manteniment

To ensure the longevity and reliable performance of your Radiolink R12DSE receiver, follow these general maintenance guidelines:

• Mantenir net: Regularly inspect the receiver for dust, dirt, or debris. Use a soft, dry brush or compressed air to gently clean the unit.
• Protegir de la humitat: Avoid exposing the receiver to moisture or extreme humidity. If it gets wet, disconnect power immediately and allow it to dry completely before re-applying power.
• Connexions segures: Ensure all wire connections are secure and free from damage. Loose connections can lead to intermittent signal loss.
• Col·locació de l'antena: Maintain proper antenna placement. Keep the antenna elements as straight as possible and away from carbon fiber or metal parts that can shield the signal.
• Font d'alimentació: Utilitzeu sempre una font d'alimentació estable dins del volum especificattage range (3-6V DC). The built-in anti-polarity protection helps prevent damage from incorrect connections, but consistent proper connection is recommended.

6. Solució De Problemes

If you encounter issues with your R12DSE receiver, consider the following troubleshooting steps:

• Receptor no vinculant:
  • Ensure the transmitter and receiver are in close proximity during the binding process.
  • Verify that the transmitter is in binding mode and the receiver's LED is flashing.
  • Check the power supply to the receiver (3-6V DC) and ensure correct polarity.
  • Confirm that your transmitter is a compatible Radiolink AT series model.
• Intermittent Signal Loss or Reduced Range:
  • Inspect antenna placement. Ensure antennas are not bent, cut, or obstructed by carbon fiber or metal components.
  • Check for sources of interference in the operating environment (e.g., Wi-Fi routers, other 2.4Ghz devices).
  • Verify the power supply to the receiver is stable and sufficient.
  • Ensure the transmitter's antenna is fully extended and oriented correctly.
• No Telemetry Data Displayed:
  • Confirm your transmitter model supports telemetry display (AT10II, AT10, AT9S Pro, AT9S, AT9).
  • For advanced telemetry, ensure the PRM-03 module is correctly connected to both the receiver and the flight controller.
  • Check all connections for security and proper orientation.
• Receiver LED Not Illuminating:
  • Verify the power connection to the receiver.
  • Check for any physical damage to the receiver or its components.
