Q7: How

can I check the wire connections

？

A7:There are 4-wire RS-422 wiring and 2-wire RS-485 wiring. The wire connection interface is shown

below.

The wire connections between Modbus masters and Modbus slaves must be follow the figure we

show below.

For non-isolated RS-422/485 ports, you should connect all signal grounds of RS-422/485

devices together. This reduces common-mode voltage between devices.

RS-485
