Normally, the parallel port is used to connect the card to a printer.
The PCM-4862 includes an on-board parallel port, accessed
through CN16, a 26-pin flat-cable connector. You will need an
adapter cable if you use a traditional DB-25 connector. The cable
has a 26-pin connector on one end and a DB-25 connector on the
other.
The PCM-4862 supports one parallel port. The port is designated
as LPT1 and can be disabled or changed to LPT2 or LPT3 in the
system BIOS setup.

The PCM-4862 board provides a keyboard connector which
supports both a keyboard and a PS/2 style mouse. In most cases,
especially in embedded applications, a keyboard is not used. The
standard PC/AT BIOS will report an error or fail during power-on
self test (POST) after a reset if the keyboard is not present. The
PCM-4862's BIOS standard setup menu allows you to select "All,
But Keyboard" under the "Halt On" selection. This allows no-
keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).
