5. Configuració
5.1. Procediment vinculant
Binding is the process of wirelessly linking the receiver to your FrSky transmitter. Ensure your transmitter is in D16 mode for optimal performance with the RX8R PRO.
- Engegueu el transmissor FrSky i navegueu fins al menú Configuració del model.
- Select the D16 mode (or D8 mode if specifically required for your setup, though D16 is recommended for RX8R PRO).
- Choose the "Bind" option on your transmitter. The transmitter will emit a beeping sound, indicating it is in bind mode.
- While holding down the F/S (Fail-Safe) button on the RX8R PRO receiver, connect power to the receiver. The red LED on the receiver will illuminate, indicating it is in bind mode.
- Once the binding process is successful, the red LED on the receiver will turn off, and the green LED will illuminate, indicating a successful bind. The transmitter will also stop beeping.
- Disconnect power from the receiver, then turn off your transmitter.
- Reconnect power to the receiver (without holding the F/S button). The green LED should now be solid, confirming the receiver is bound and receiving a signal from the transmitter.
- Turn on your transmitter. The green LED on the receiver should remain solid.
Nota: If the binding fails, ensure your transmitter firmware and receiver firmware are compatible. Refer to the FrSky website for the latest firmware updates and compatibility information.
5.2. Connexions de cablejat
The RX8R PRO offers multiple output options for connecting to your flight controller or servos.
- PWM Outputs (Channels 1-8): Connect individual servos or other PWM-controlled devices to these pins. Channels 1-8 provide direct PWM output.
- SORTIDA SBUS: Connect to a flight controller that supports SBUS input for a single-wire connection carrying all 16 channels.
- ENTRADA DE SBUS: Used for redundancy setups, allowing connection of a second receiver (e.g., another RX8R PRO or an XSR) to provide a backup signal.
- Port intel·ligent (S.Port): Connect telemetry sensors or other Smart Port compatible devices. This port also allows for firmware updates.
- Power (VCC/GND): Connect a stable power source within the operating voltagrang e (3.5V-10V).
Always ensure correct polarity when connecting power to avoid damage to the receiver.
6. Instruccions de funcionament
Once bound and correctly wired, the RX8R PRO receiver operates by receiving control signals from your FrSky transmitter and transmitting telemetry data back to the transmitter.
- Funcionament normal: With the transmitter and receiver powered on, the green LED on the receiver should be solid, indicating a stable connection.
- Telemetria: Ensure your transmitter is configured to display telemetry data. The RX8R PRO will automatically send data such as RSSI (Received Signal Strength Indication) and receiver voltage back to the transmitter. Additional sensors connected to the Smart Port will also transmit their data.
- Seguretat contra errors: It is crucial to set up fail-safe on your transmitter. In case of signal loss, fail-safe ensures that your model's servos move to predefined positions (e.g., throttle to zero, control surfaces neutral) to prevent uncontrolled flight. Refer to your transmitter's manual for fail-safe setup instructions.
- Redundància: If using the redundancy feature with a second receiver connected to SBUS IN, the system will automatically switch to the receiver with the stronger signal in case of signal degradation from the primary receiver.
7. Manteniment
To ensure the longevity and reliable performance of your RX8R PRO receiver, follow these maintenance guidelines:
- Col·locació de l'antena: Ensure antennas are mounted at a 90-degree angle to each other and away from carbon fiber, metal, or other conductive materials that can shield the signal. Do not cut or modify the antenna wires.
- Protecció del medi ambient: Protect the receiver from moisture, dust, and extreme temperatures. Consider using heat shrink or a protective case in harsh environments.
- Actualitzacions de firmware: Periodically check the FrSky website for firmware updates. Updating the receiver firmware can improve performance, add new features, or address compatibility issues. Use the Smart Port for firmware updates.
- Gestió de cables: Secure all wiring to prevent accidental disconnections or interference with moving parts.
8. Solució De Problemes
- Problem: Receiver does not bind.
- Solució:
- Ensure the transmitter is in D16 mode (or D8 if applicable) and in bind mode.
- Verify the F/S button on the receiver is held down while connecting power during the bind process.
- Comproveu la compatibilitat del firmware entre el transmissor i el receptor. Actualitzeu el firmware si cal.
- Ensure the receiver is receiving adequate power (3.5V-10V).
- Try binding at a closer distance to the transmitter.
- Problem: No signal/Green LED not solid after binding.
- Solució:
- Confirm the transmitter is powered on and operating on the correct model memory.
- Re-bind the receiver to the transmitter.
- Comproveu les connexions i la col·locació de l'antena.
- Ensure no strong local interference sources are present.
- Problem: Servos not responding or erratic behavior.
- Solució:
- Verify all servo connections are correct (signal, positive, negative).
- Check the power supply to the servos and receiver.
- Ensure the correct channel mapping is set on your transmitter.
- Inspect for physical damage to servos or wiring.
- Problem: Telemetry data not displayed.
- Solució:
- Ensure the Smart Port connection is secure.
- Verify telemetry sensors are correctly connected and functioning.
- Check your transmitter's telemetry setup menu to ensure sensors are discovered and displayed.
- Confirm the receiver firmware supports telemetry for your specific transmitter model.
