Communication Protocol

    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 03 05 CB .
Address Function Code Start Address Data Length Check Code
01 03 00 00 00 03 05 CB
    For the correct query frame, the device will respond with data: 01 03 06 00 7B 00 00 00 00 C5 7F , response format:
Address Function Code Length Data 1 Data 2 Data 3 Check Code
01 03 06 00 79 00 7A 00 7B C5 7F
    Data description: The data in the command is hexadecimal, take data 1 as an example, 00 79 is converted to decimal value as 121, assuming the data magnification is 100, then the real value is 121/100=1.21, Others and so on.
