It is possible to connect either an OP1S or a PC with RS232 or RS485
serial interface via the 9-pole SUB D socket. There are different
connecting cables for the PC for the various transmission protocols.
The 9-pole SUB D socket is internally coupled with the USS bus, thus
enabling data exchange with other nodes linked via the USS bus.
This interface is also used for loading software.
