Three IC485S devices are necessary in a client environment, and one of them needs to be set to Monitor mode.
This is because the PC is not an IC485/422 device, so we need to use an extra IC485S device to connect to the PC.
- Device1 (PC 1 + IC485S) - Device2 (PC 2 + IC485S) - IC-485S + Monitor PC (Two COM ports are necessary)
Users have to install a cable between the IC-485 DB25 interface and the Monitor PC COM 1, and COM 2 as below:
IC485 DB25 TX Pin -> Monitor PC COM 1 RX Pin IC485 DB25 RX Pin -> Monitor PC COM 2 RX Pin
