communication
1. And RS 485 communication
The communication mode of the flowmeter is RS 485, and there are two protocol modes: (the factory default is B mode)
A. Factory calibration communication protocol, as a stand-alone communication protocol;
B. Modbus Agreement, for the multi-machine communication protocol.
The settings are as, respectively:
Paud 9600 (A) / 9600 (B);
Data bit 8;
Stop bit 1;
Check bit / flow control has no.
Communication protocol see: CAFS 5000 series gas mass flowmeter upper computer Modbus communication protocol
