5. Setup

5.1. Connecting the Receiver

Refer to the diagram below for proper connection of the FS-X6B receiver to your flight controller and other components. Ensure correct polarity when connecting power.

Figure 5.1: Wiring diagram for the FS-X6B receiver, showing PWM, PPM, i-BUS, GND, VCC, and voltage detection ports.

• PWM Output: Connect individual servo leads to CH1-CH6 for traditional PWM control.
• PPM Output: Connect the PPM port to your flight controller for a single-wire PPM signal.
• i-BUS Output: Connect the i-BUS port to your flight controller for a single-wire digital i-BUS signal, supporting up to 18 channels.
• Voltage Detection: Use the voltage detection port to monitor the flight battery voltage (if supported by your flight controller/transmitter).

5.2. Binding the Receiver

To establish communication between your FS-X6B receiver and a compatible Flysky AFHDS 2A transmitter, you must perform a binding procedure.

1. Ensure your transmitter is powered off.
2. Connect a bind plug (or short the BIND pins) to the BIND port on the FS-X6B receiver.
3. Apply power to the FS-X6B receiver (e.g., via a flight controller or external BEC). The receiver's LED should start flashing rapidly, indicating it is in binding mode.
4. While holding the BIND button on your transmitter (if applicable, or follow your transmitter's specific binding instructions), power on the transmitter.
5. The receiver's LED should stop flashing and become solid, indicating a successful bind.
6. Release the BIND button on the transmitter and power off both the receiver and transmitter.
7. Remove the bind plug from the receiver.
8. Power on the transmitter first, then the receiver. The receiver's LED should be solid, confirming the connection.

Note: The exact binding procedure may vary slightly depending on your specific Flysky transmitter model. Always refer to your transmitter's manual for detailed instructions.

6. Operating

Once successfully bound, the FS-X6B receiver will communicate with your transmitter.

• Power On Sequence: Always power on your transmitter first, then your multi-rotor aircraft (which powers the receiver). When powering off, disconnect the aircraft battery first, then power off the transmitter.
• Signal Loss: In case of signal loss, the receiver will enter failsafe mode. Ensure your flight controller is configured to handle failsafe appropriately (e.g., land, return to home).
• Firmware Update: The FS-X6B supports wireless firmware updates. Refer to the Flysky official website or support resources for instructions on how to perform updates, which can improve performance or add new features.

7. Maintenance

Proper maintenance ensures the longevity and reliable operation of your FS-X6B receiver.

• Keep Clean: Regularly inspect the receiver for dirt, dust, or debris. Use a soft, dry brush or compressed air to clean. Avoid using liquids.
• Antenna Care: Ensure antennas are not bent, cut, or damaged. Position them at a 90-degree angle to each other for optimal signal reception. Do not shorten or extend the antennas.
• Environmental Protection: Protect the receiver from moisture, extreme temperatures, and direct sunlight. Consider using conformal coating or a protective enclosure if operating in harsh environments.
• Connection Integrity: Periodically check all wire connections to ensure they are secure and free from corrosion or fraying.
