Baud Rate: 57600; Data: 8 bytes; Stop: 1 byte; Parity: None.

After power-on, the detector will use around 3 seconds to complete the self-test. If there is an issue, the detector will

repeat self-testing until the problem is solved. After booting up, the serial port will send out data in the following format:
