Intel SBC-455 manual Parallel port Printer, Installing the retaining bracket

Parallel port (PRINTER)

Normally, the parallel port is used to connect the card to a printer. The SBC-455 includes an on-board parallel port, accessed through the PRINTER 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, 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 the PRINTER connec- tor. 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 the PRINTER connector. Pin 1 is on the right side of the PRINTER connec- tor.
