Parallel port connector (CN3)
Normally, the parallel port is used to connect the card to a printer.
The PCM-4894 includes an onboard parallel port, accessed
through the CN3 connector, a 26-pin flat-cable connector. The
CPU card comes with an adapter cable, which lets 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.
