6 Communication Instructions

The RS485 communication interface of the instrument supports MODBUS-RTU communication protocol, and the baud rate of the communication port can be set between 1200bps, 2400 bps, 4800bps, 9600bps, 19200 bps, and 38400 bps, with no checksum.

The RS485 communication port of the instrument requires the use of shielded twisted pair cables for connection. When wiring, the layout of the entire network should be considered, such as the length and direction of communication cables, the position of the upper computer, the matching resistance at the end of the network, communication converters, network scalability, network coverage range, and electromagnetic interference in the environment, all of which need to be comprehensively considered.

Note:

1. Strictly follow the requirements for wiring engineering construction;

2. For instruments that do not require communication temporarily, they should be connected to the RS-485 network for diagnosis and testing purposes;

3. When connecting RS-485 cables, try to use dual color twisted pair cables, and connect all 485 communication ports with the same color on the "A" end and another color on the "B" end.

4. The RS-485 bus (from the communication port of the upper computer to any connected instrument terminal communication port) shall not exceed 1000 meters in length.
