Aaeon SBC-357 Manual page 24

Normally, the parallel port is used to connect the card to a printer.
The SBC-357 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, mounted on a retaining bracket.
The retaining bracket installs at an empty slot in your system's
chassis. It provides an external port that gives your parallel
peripheral 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 CN3 connector.
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 CN3 connec-
tor. Pin 1 is on the right side of the CN3 connector.
