On the rear panel, there is a combo connector which comprises three DSUB connectors, one for the

parallel port LPT, one for the serial port COM1, and one for VGA signals.

The LPT port is provided via a 25pin DSUB connector (female).

The serial interface COM1 is made available via a 9-pin standard DSUB-connector. According to the

product order, TTL level signals or RS232 standard signals are provided.

The port address and the interrupt are set via the BIOS setup.

The remaining 15pin DSUB connector (female) is used to attach a VGA display.
