9-Pin subD Connector

The pin assignment of this 9-pin subD connector follows the requirements of an RS232 standard interface with the
RS232 voltage level. The cable (see section "Connecting Cables") which has to be used is a standardized serial
interface cable which allows to connect a data device with an RS232 Interface such as PC, Laptop, Console.
