Port 0, 1, 2, 3: RS-485 Interface Connections

The following illustration applies when the RS-485 interface is selected.

NOTE: This type of connection is commonly called a RS-485 half-duplex, 2-wire connection. If you

have RS-485 4-wire, full-duplex devices, they can be connected to the gateway's serial ports by

wiring together the TxD+ and RxD+ from the two pins of the full-duplex device to Pin 1 on the

gateway and wiring together the TxD- and RxD- from the two pins of the full-duplex device to Pin 8

on the gateway. As an alternative, you could try setting the gateway to use the RS-422 interface

and connect the full-duplex device according to the RS-422 wiring diagram (page 47). For

additional assistance, please contact ProSoft Technical Support.
