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 04 44 09 .
| Address | Function Code | Start Address | Data Length | Check Code |
| 01 | 03 | 00 00 | 00 04 | 44 09 |
For the correct query frame, the device will respond with data: 01 03 08 00 79 00 00 00 00 00 00 7D 10 , response format:
| Address | Function Code | Length | Data 1 | Data 2 | Data 3 | Data 4 | Data 5 |
| Data 6 | Data ... | Data 7 | Data 8 | Check Code | 01 | 03 | 08 |
| 00 79 | 00 7A | 00 7B | 00 7C | 00 7D | 00 7E | ...... | ......00 79 |
| 00 79 | 7D 10 |
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.
