5. Configuració

5.1. Lligament del receptor

The R12F receiver is typically pre-bound to compatible Radiolink transmitters when purchased as a kit. If you need to bind a new receiver or re-bind an existing one, follow these steps:

1. Power on your compatible Radiolink transmitter.
2. Locate the binding button on the side of the R12F receiver.
3. Press and hold the binding button while powering on the R12F receiver. You can supply power via the USB-C port or by connecting an ESC.
4. The LED on the receiver will flash rapidly, indicating it is in binding mode.
5. The receiver will automatically bind to the closest compatible transmitter. Once bound, the LED will turn solid.

5.2. Actualització del firmware

To access the latest features and ensure optimal performance, it is recommended to keep your R12F firmware updated. The receiver supports online firmware updates.

1. Download the latest firmware from the official Radiolink weblloc.
2. Connect the R12F receiver to your computer using a Type-C USB cable. The cable can also supply power to the receiver, eliminating the need for a separate battery connection during the update.
3. Hold the binding button on the receiver while plugging it into the computer. The receiver will appear as a drive on your computer.
4. Drag and drop the downloaded firmware file into the receiver's drive.
5. Safely eject the receiver from your computer. The firmware update is now complete.

5.3. Connecting Servos and Power

The R12F receiver supports PWM, SBUS, and CRSF signal outputs. Connect your servos and ESCs to the appropriate channels on the receiver. The receiver supports a wide voltage input of 3-12V, allowing for high-voltage servos. It also features anti-polarity connect protection, preventing damage if polarities are mistakenly connected.

6. Funcionament

6.1. Simulator Function

The R12F receiver can be used with open-source simulators without requiring a separate dongle. This feature requires the R12F firmware to be updated to V1.6 or above. Simply connect the receiver to your computer via a Type-C cable, and it will function as a PC Game Joystick communication program. Compatible simulators include AeroFly, Uncrashed, Liftoff, Tryp FPV, FPV LogicV, Velocidrone, and more.

6.2. Telemetry and Voltage Alarmes

The R12F receiver can provide telemetry data, including external voltage, back to your compatible transmitter. If you are not utilizing the external voltage telemetry feature, you may receive continuous low voltage alarms from your transmitter. To disable this, navigate to your transmitter's receiver settings, then sensors, and turn off the external voltage alarm. The default low voltage alarm is typically set to 3.5V.

6.3. Control Surface Adjustments (End Points & Trims)

Adjusting end points and trims is crucial for precise control of your model. Access these settings through your transmitter's menu. For example, if your flaps are not flush with the wing in the up position, you can adjust the trim for the corresponding channel (e.g., Channel 6) to a negative value until the desired position is achieved. Similarly, end points can be adjusted to prevent over-stressing servos.

6.4. Auxiliary Channel Settings

The R12F offers 12 channels. Channels 1-4 are typically fixed for Aileron, Elevator, Throttle, and Rudder (AETR). Channels 5-12 can be assigned to various switches or potentiometers on your transmitter to control auxiliary functions like flaps, landing gear, or other model features. You can change these assignments within your transmitter's auxiliary channel settings.

7. Compatibilitat

The Radiolink R12F receiver is compatible with a range of Radiolink transmitters, including T16D, T12D, T8FB, T8S, RC8X, RC6GS V3, RC4GS V3, RC6GS V2, RC4GS V2, RC6GS, and RC4GS. It supports various model types such as helicopters, fixed-wing aircraft, gliders, multi-rotors, engineering vehicles, racing boats, robots, lawnmowers, bait boats, and mechas.

9. Solució De Problemes

9.1. Motor Beeping Continuously

If your motor beeps continuously upon initial connection, it might indicate a low voltage alarm from the transmitter due to unconfigured telemetry. Refer to section 6.2 on how to disable the external voltage alarm in your transmitter settings if you are not using telemetry.

9.2. Binding Issues

If the receiver does not bind or loses connection, ensure the receiver firmware is up to date (refer to section 5.2). Also, verify that the binding process (section 5.1) is followed correctly, ensuring the binding button is held while powering on the receiver.

9.3. Control Surface Movement Issues

If control surfaces move in the wrong direction or have excessive travel, adjust the 'Reverse' and 'End Points' settings in your transmitter's general settings (refer to section 6.3). Incorrect settings can stress servos and lead to premature failure.

10. Manteniment

Keep the receiver clean and free from dust and moisture. Avoid exposing it to extreme temperatures. Regularly check all wiring and connections for signs of wear or damage. Ensure antennas are not cut or damaged, as this can significantly reduce range and performance.
