SIYI FM30 Transmitter Frequency Matching
I. Principle
SIYI FM30 is a high-frequency head module that integrates remote control and telemetry functions, designed specifically for drones and remote control models. It operates on the 2.4GHz frequency band, providing ultra-long-range communication capabilities, and includes a built-in Bluetooth module for convenient flight controller parameter tuning and flight status monitoring. The following explains how to bind the SIYI FM30 with a receiver.

III. Specific Operations
Step 1: Configure High-frequency Head Protocol
- Adjust the high-frequency head mode: Turn the SIYI FM30 high-frequency head rear knob to SBUS mode.

- Set the RC transmitter external high-frequency head protocol: Short press the MDL key to enter the model menu. Find the External RF setting and select SBUS mode.
- Color screen settings:

- Black and white screen settings:

- When the RC transmitter and high-frequency head establish successful communication, the high-frequency head STA green light will remain on, and the RF red light will remain on.

Step 2: Binding - Enter binding mode: Long press the high-frequency head Bind button until the RF red light flashes rapidly, entering binding mode.

- Receiver binding: Connect the receiver to the flight controller. Power on the receiver for 5 seconds until the red light flashes slowly. Long press the receiver's bind button until the red light flashes rapidly, entering binding mode.

- Confirm successful binding: The high-frequency head RF indicator green light flashing indicates successful connection to the receiver. The receiver green light remaining on indicates binding is complete and communication is normal.

- After successful binding, return to the RC transmitter main page to view the signal strength.
