2.4 Parallel Port (LPT1)
Figure 2.3 PCI-7031 LPT1 location
The parallel port is normally used to connect the single board computer to a printer.
The PCI-7031 includes an onboard parallel port, accessed through a 26-pin flat-cable
connector, LPT1. The card comes with an adapter cable which lets you use a tradi-
tional 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 bracket installs at the
end of an empty slot in your chassis, giving you access to the connector.
The parallel port is designated as LPT1, and can be disabled or changed to LPT2 or
LPT3 in the system BIOS setup.
To install the bracket, find an empty slot in your chassis. Unscrew the plate that cov-
ers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flat-
cable connector to LPT1 on the CPU card. Wire 1 of the cable is red or blue, and the
other wires are gray. Make sure that wire 1 corresponds to pin 1 of LPT1. Pin 1 is on
the upper right side of LPT1.
