Online communication | The communication interface is a two-wire, three-wire or four-wire system (such as RS-485, RS-232C, RS-422, etc.), and the baud rate of 300-9600bps can be freely set by the internal parameters of the instrument. The interface and the host can be photoelectrically isolated, and the communication distance can reach 1.2 kilometers. The system adopts a master-slave communication method, and the entire control loop only needs a two (three, four) core cable to achieve communication with the host computer. |
