DSUB-connectors
9-pin DSUB-sockets are used for serial interfaces with electrical connection (Figure 13).
Usual 9-pin DSUB-plugs according MIL-C-24308 and DIN 41652 can be used for the data-
cable connection.
The data-cable depends on the type of the interface:
RS232: 3-core or 5-core screened, e.g. interface cable 7XV5100–4.
RS485: 3-core data-cable, twisted and screened.
Profibus: 2-core, twisted and screened.
