Read Serial (RS485) Data

[admin]

The serial port is connected, could u please send me a command that I can use for testing. For example read relays statuses or turn on/off single relay.

if your KC868-Server RS485 address is "1" and "9600bps" have set. You can send these commands by serial port to test whether output1 is ON or OFF.

turn relay1 on: 01 05 00 00 FF 00 8C 3A
turn relay1 off: 01 05 00 00 00 00 CD CA
