Parallel port (PRINTER PORT)
Normally, the parallel port is used to connect the card to a printer.
The PCM-3335 includes an on-board parallel port, accessed
through PRINTER PORT, and 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, mounted on a
retaining bracket.
Installing the retaining bracket
The retaining bracket installs at an empty slot in your system's
chassis. It provides an external port that allows your parallel
peripheral to access to the card's parallel port connector.
1. Find an empty slot in your chassis.
2. Unscrew the plate that covers the end of the slot.
3. Screw in the bracket in place of the plate.
4. Next, attach the flat-cable connector to PRINTER PORT. Wire
1 of the cable is red or blue, and the other wires are gray. Make
sure that Wire 1 connects to Pin 1 of PRINTER PORT. Pin 1 is
on the right side of PRINTER PORT.
