Pinout of the X1 and X2 connectors
The X1 connector is designed as a 9-pin D-sub miniature male connector. The pinout is
shown in the following table. As an RS-232 port, the pinout corresponds to that of a
standardized PC connector.
The connector can be configured either as an RS-232 or as an RS-485 port using the 8-pin
DIL switch available from above through the grill in the housing.
Table 5-12
The X2 MPI connector is designed as a 9-pin D-sub miniature female connector. The pinout
is shown in the following table.

Note
The MPI connector does not supply 24 V for external devices. TS adapters and MPI adapter
cables for laptops cannot therefore be connected.
