To control the color, display effect, and sound effect of the Beacon Sounder using the serial interface, follow these steps:

1. Power Options: The beacon sounder can be powered by either connecting a 9-30VDC (min 10W) power supply to terminal J4 or by using a 5VDC (+/- 0.1V) 2A power supply connected to terminal J2. Ensure proper wiring and connections as per the manual.

2. Serial Protocol Specification: Set DIP switch FN 3 to "ON" to configure the beacon sounder for serial input. The serial commands consist of a 7-byte string with the following layout:

- Byte 0: ASCII 'X' (Synchronization character)

- Byte 1: Display mode (ASCII Hex)

- Byte 2: Red (ASCII Hex)

- Byte 3: Green (ASCII Hex)

- Byte 4: Blue (ASCII Hex)

- Byte 5: Sound mode (ASCII Hex)

- Byte 6: CRC (ASCII Hex)

3. Light and Sound Modes: The beacon sounder supports various sound and light modes. Refer to the manual for the corresponding values of sound mode and light mode to achieve the desired effects.

4. Example Code: The manual provides example C code to implement the protocol for controlling the Beacon Sounder. The code includes a function to set the sound mode, light mode, and color of the beacon sounder. Ensure the code is adapted to your specific requirements and system setup.

5. Wiring and Connections: Pay close attention to the wiring connections, especially when using the serial interface. Follow the pinout details for J2 and ensure the signal voltage and cable length requirements are met.

By following these steps and referring to the detailed instructions in the user manual, you should be able to effectively control the color, display effect, and sound effect of the Beacon Sounder using the serial interface.
