Q: What is RS485 communication port

A: Through the inbuilt RS485 standard interface, the SJR3-2000 series soft starter can connect with PC and PLC and other hosts to conduct serial communication. The command of the host can control running or stop of the soft starter, monitor the running status of the soft starter and modify its functional data. Please refer to RS485 operation instructions for the detailed information of the communication. Remote operation, running command input, running status management, write-once of functional data of several soft starters can be conducted by means of the RS485 communication through computers to implement simplified operation during function codes input.

Q: What's the major functions of RS485 communication port

A: I. Input of stop running command

2. Monitoring of the running status

3. Real-time tracking(tabular display of the running information

4. Read-once, write-once and saving to files of function codes. Please consult our company separately for the communication software.
