PLC 1 PORT OF GWY-S7
PLC1 port of GWY-S7 has a DB9 female type connector and is compatible with RS232C, RS422, RS485
and CMOS signal levels. Pin outs of this port are as given below:
RS485 port:
RS485 port of Gateway can have any of the following two pin outs, depending on the model number. User
can configure this port either as 4 wire + Signal Ground or 2 wire + Signal Ground.
PLC2 port of GWY-02, GWY-04, GWY-06 and GWY-08 models
This port has a 6x1 pin PCB Terminal Block type connector with following pins:
1. TX+
2. TX-
3. RX+
4. RX-
5.Termination
6. SG
Termination should be shorted with RX- for first and last node in a RS485 network.
PLC1 port of GWY-04 and GWY-08 models
This port has a 4x2 pin PCB Terminal Block type connector with following pins:
1. TX+
2. RX+
3.Termination
4. GND
5. TX-
6. RX-
7. +5 VDC (GWY-04) / +24VDC (GWY-08)
8. PLC Attach
Termination should be shorted with RX- for first and last node in a RS485 network. PLC attach line should be
connected to ground when PLC is attached on this port, else when Gateway has to be configured, leave PLC
Attach line open.
