5. Operation Description
1. Transmitter configuration mode
The parameters of the transmitter can be modified through the serial port, including: setting the
content of transmission data, modifying the transmitter ID, setting the transmission time interval,
and reading the transmitter ID. The format of the serial port is 9600, 8, N, 1, and the data content
is (HEX) hexadecimal, with 0x0D 0x0A as the end sign. The minimum interval between two
consecutive setting commands is 100ms.
The module automatically verifies the input command. If the command is correct, the hexadecimal
return "OK\r\n" is 0x4F 0x4B 0x0D 0x0A. The error return "ERROR\r\n" hexadecimal is 0x45
0x52 0x52 0x4F 0x52 0x0D 0x0A
Users can directly connect the module to the PC through our USB adapter board, and use the
serial port assistant to operate.
