2.3 Parallel Port Connector (CN8)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6175 includes an on-board parallel port, accessed
through a 26-pin flat-cable connector, CN8. The 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 bracket installs at the
end of an empty slot in your chassis, giving you access to the connec-
tor.
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 covers the end of the slot. Screw in the bracket in place of
the plate. Next, attach the flat-cable connector to CN8 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 CN8. Pin 1 is on the
upper right side of CN8.
2.4 Keyboard & PS/2 Mouse Connector (CN12)
The PCA-6175 board provides a keyboard connector. A 6-pin
mini-DIN connector (CN12) on the card mounting bracket supports
single-board computer applications. The card comes with an adapter
to convert from the 6-pin mini-DIN connector to a standard DIN
connector and to a PS/2 mouse connector.
