8-4 Operating Manual: PSS 3075-3 Series
Programming device interface RS 485
If you need to cover longer distances between the programming device
and PSS (from approx. 15 m), use the RS 485 interface on the PSS.
If the programming device has no RS 485 interface, connect the RS 485
interface on the PSS to the RS 232 interface on the programming device
via the C-PC-PAP-2 interface adapter (order no. 305 155).
To connect the PSS to the programming device or to the interface adapter,
you will need a cable with a layout as shown in Fig. 8-3. This cable is
available under order number 374 205. It contains all the necessary links.
