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 02 C4 0B .
Address Function Code Start Address Data Length Check Code
010300 0000 02C4 0B
    For the correct query frame, the device will respond with data: 01 03 04 00 79 00 00 2B EA , response format:
Address Function Code LengthData 1Data 2Data 3

Check Code0103 0400 7900 7A
00 7B00 7C00 7D00 7E............00 79
00 79 2B EA
    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.
