2. Wiring Diagram and Pinout

Detailed wiring diagram for the FBr12 receiver. Pins [1]-[8] are for CH1-CH8. Pin [9] is CH9(NPD), [10] is Bind. Pins [11] CH10(NPC), [12] CH11(NPB), [13] CH12(NPA). Pin [14] is for battery negative pole, [15] for battery positive pole, [16] is the Signal pin. [17] indicates the antennas, and [18] is the LED indicator. A 'Forced Update Interface' is also shown.

2.1 Pin Definitions

• [1]-[8] CH1-CH8: Standard PWM output channels.
• [9] CH9(NPD): Channel 9 output.
• [10] Bind: Pin for initiating the binding process.
• [11] CH10(NPC): Channel 10 output.
• [12] CH11(NPB): Channel 11 output.
• [13] CH12(NPA): Channel 12 output.
• [14] - (Connect to battery negative pole): Ground connection.
• [15] + (Connect to battery positive pole): Power input (3.5-9V).
• [16] S (Signal pin): Signal output for serial protocols (i-BUS, S.BUS, i-BUS 2).
• [17] Antenna: Dual external antennas for signal reception.
• [18] LED: Status indicator light.

3. Binding Procedure

To establish communication between the FBr12 receiver and your transmitter, follow these binding steps:

1. Ensure your transmitter supports the AFHDS 3 protocol (e.g., PL18, NB4, NB4 Lite).
2. Connect power to the FBr12 receiver (3.5-9V).
3. Locate the 'Bind' pin on the receiver (Pin [10] as per the wiring diagram).
4. Initiate the binding process on your transmitter according to its specific instructions.
5. While the transmitter is in binding mode, activate the bind function on the receiver. This typically involves shorting the bind pins or pressing a bind button, as indicated by your transmitter's manual.
6. The LED indicator on the receiver (Pin [18]) will change state to confirm successful binding.

Operating Instructions

Once successfully bound, the FBr12 receiver will output control signals to your RC model. The receiver supports various data output types:

• PWM: Pulse Width Modulation for standard servo control.
• PPM: Pulse Position Modulation.
• i-BUS: Flysky's serial data bus.
• S.BUS: Futaba's serial data bus.
• i-BUS 2: An enhanced version of Flysky's serial data bus.

Connect your servos, ESCs, and other components to the appropriate PWM channels (CH1-CH12) or utilize the serial data output for compatible devices. Refer to your transmitter's manual for specific channel assignments and configuration.

Maintenance

Firmware Updates

The FBr12 receiver supports online firmware updates. Refer to the Flysky official website or your transmitter's software for the latest firmware and update procedures. Use the 'Forced Update Interface' as shown in the wiring diagram if required.

Care and Storage

Despite its IPX7 waterproof rating, it is recommended to rinse the receiver with fresh water after exposure to saltwater and ensure it is completely dry before storage. Store the receiver in a dry, cool place away from direct sunlight and extreme temperatures.

Troubleshooting

Common Issues

No Signal / Loss of Connection

• Verify the receiver is powered correctly (3.5-9V).
• Ensure the receiver is properly bound to the transmitter. Re-perform the binding procedure if necessary.
• Check antenna placement. Ensure antennas are not obstructed and are positioned for optimal signal reception.
• Confirm the transmitter's battery level is sufficient.
• Check for interference from other 2.4Ghz devices in the vicinity.

Incorrect Channel Output

• Verify the channel assignments in your transmitter's settings.
• Ensure servos/ESCs are connected to the correct PWM pins on the receiver.
