Receiver Port Descriptions:

• [1] CH1 (PPM): Channel 1 output, also supports PPM signal.
• [2]-[8] CH2-CH8: Channels 2 through 8 outputs.
• [9] CH9 (NPD): Channel 9 output.
• [10] CH10 (NPC): Channel 10 output.
• [11] CH11 (NPB): Channel 11 output.
• [12] i-bus in (CH12/NPA): i-Bus input, also functions as Channel 12 or NPA.
• [13] VCC/BVD (Battery voltage detection / power supply interface): Port for battery voltage detection and main power input.
• [14] LED: Status indicator light.
• [15] Antenna: Receiver antenna for signal reception.
• [16] BIND: Bind button for pairing with a transmitter.
• [17] S (Signal Pin): Signal pin for connections.
• [18] + (Positive power terminal): Positive power connection.
• [19] - (Power ground): Ground connection.
• [20] Same as [17]: Signal pin.
• [21] Same as [18]: Positive power connection.
• [22] Same as [19]: Ground connection.
• [23] BVD harness: Harness for Battery Voltage Detection.
• [24] Connect to battery positive pole: Connection point for positive battery terminal.
• [25] Connect to battery negative pole: Connection point for negative battery terminal.

Important Tips:

• The added new NPA/B/C/D and BVD functions will be available with the release of a new firmware update in November 2020. The BVD harness [17] will not function until the new firmware has been installed.
• The [8] i-bus/S.bus terminal will be replaced with the CH8 (NPA) function after the firmware upgrade.

Setup

Binding Process:

Binding is the process of pairing your FGr12B receiver with your AFHDS 3 compatible transmitter. Follow these general steps:

1. Ensure your transmitter is powered off.
2. Connect a bind plug (if required by your transmitter/receiver combination) to the BIND port [16] on the FGr12B receiver. Alternatively, some transmitters may have a bind button on the receiver itself.
3. Apply power to the FGr12B receiver (e.g., connect it to your RC model's power source or a separate battery). The LED [14] on the receiver should start flashing rapidly, indicating it's in bind mode.
4. While holding the bind button on your transmitter (or following its specific bind procedure), power on the transmitter.
5. The LED on the receiver should change from rapidly flashing to solid, indicating a successful bind.
6. Release the bind button on the transmitter (if applicable) and power off both the receiver and transmitter.
7. Remove the bind plug from the receiver (if used).
8. Power on the transmitter first, then the receiver. The receiver's LED should be solid, confirming the connection.

Connecting to your RC Model:

Refer to the "Product Overview" section for a detailed diagram of the receiver's ports. Connect your servos, ESC (Electronic Speed Controller), and other components to the appropriate PWM channels (CH1-CH11) or utilize the i-Bus output for compatible systems. Ensure correct polarity (+, -, S) when making connections to avoid damage.

Operation

Once the receiver is successfully bound to your transmitter and all components are correctly connected, you can begin operating your RC model. Always power on your transmitter first, then your receiver/model. When finished, power off your receiver/model first, then your transmitter.

• Pre-flight/Pre-run Check: Before each use, ensure all connections are secure, the receiver LED is solid (indicating a strong link), and all control surfaces/motors respond correctly to transmitter inputs.
• Range Check: Perform a range check in an open area to ensure reliable signal reception at a safe distance.
• Environmental Considerations: Avoid operating your RC model in areas with strong electromagnetic interference, which can affect receiver performance.

Maintenance

Proper maintenance will extend the lifespan of your FGr12B receiver:

• Cleaning: Keep the receiver clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Avoid using solvents or harsh chemicals.
• Moisture Protection: While the receiver has an IPX4 rating (splash resistant), avoid prolonged exposure to water or high humidity. If it gets wet, ensure it is completely dry before reapplying power.
• Physical Protection: Mount the receiver securely within your model to protect it from vibrations and impacts.
• Antenna Care: Ensure the antenna is not cut, kinked, or damaged. A damaged antenna can significantly reduce range and signal reliability. Position the antenna away from metal objects and carbon fiber to maximize signal reception.
• Firmware Updates: Periodically check the GoolRC or Flysky official website for any available firmware updates for the FGr12B receiver. Updates can improve performance and add new features.
