Interface of the PS4-201 (RS232)

This Multiplexer have 3 ports with Sub-D-connectors. These connectors have at both ports

the pining of an inverted PC-port (its the counterpart of a PC-port). So you can use a 1:1

cable. The PLC port have the same pining as a PC, so you can use the original PLC cable to

connect the MUX with the PLC.

For the connection to a PS4-201, the connection cables must be make by yourself, because the

operation panels often have a 9-pin-connector, but not the rounded DIN-connectors. The

cable must be customised with regarding at the connector assignment of the PG-MUX and the

connector assignment of your operation panel. The connection cable to the PC must be a 9 pol

1:1 cable. The bridges who were needed by the PG-software are connected internally in the

PG-MUX at both PG connectors.

If you want to make you own cable with the rounded connector ,you need a DIN 41524

connector with 8 pins.
