Chapter 2 Installation 23
Parallel port (PRINTER)
Normally, the parallel port is used to connect the card to a
printer. The SBC-410 includes an on-board parallel port, which
is accessed through a 26-pin flat-cable connector. The CPU
card comes with an adapter cable, which lets you use a tradition-
al 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 on the
CPU card. 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
PRINTER.
