Gender Changer for COM1
You can convert the COM1/V24 / AG port of the SIMATIC PC family into the usual 25 pin male connector by means of the enclosed gender changer (25 pin / 25 pin). For this, you only have to plug the gender changer onto the COM1 socket and secure it with the two hexagon head screws.
The V24 and TTY interfaces for COM1 can be alternately used. The factory set default value is V24 operation. Switching from V24 to TTY operation is described in Section 5.1.2.
