Pin assignment (9-pin Sub-D, plug)
(Standard for the RS232/422-model, optional for the RS232/485-model)
Attention:
The assignment of the 9-pin Sub-D plug may differ from the above pin
assignment and also a customized configuration is possible.
Attention:
In case the RS-interface is NOT potentially divided, "GND" and "supply
0V" are connected internally.
