Pinout of the RS-232 and RS-485 ports
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 RS-232 interface can be activated using a 4-pin DIL switch accessible from below
through the housing grill.
