    The product uses RS485 MODBUS-RTU standard protocol format, all operation or reply commands are hexadecimal data. The default device address is 1 when the device leaves the factory, and the module or NON-Recorder default baud rate is 9600,8,n,1 ,but data recorder default baud rate is 115200 .
1. Read data (function code 0x03)
    Inquiry frame (hexadecimal), sending example: query 1 data of 1# device, the upper computer sends the command: 01 03 00 00 00 0A C5 CD .
Address Function Code Start Address Data Length Check Code
010300 0000 0AC5 CD
    For the correct query frame, the device will respond with data: 01 03 14 00 79 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 26 31 , response format:
