2.7 FDD connector (CN2)
You can attach up to two floppy disk drives to the PCA-6740's
onboard controller. You can use any combination of 5.25" (360 KB/
1.2 MB) and/or 3.5" (720 KB/1.44/2.88 MB) drives.
The card comes with a 34-pin daisy-chain drive connector cable. On
one end of the cable is a 34-pin flat-cable connector. On the other end
are two sets of floppy disk drive connectors. Each set consists of a 34-
pin flat-cable connector (usually used for 3.5" drives) and a printed-
circuit-board connector (usually used for 5.25" drives). You can use
only one connector in each set. The set on the end (after the twist in
the cable) connects to the A: floppy. The set in the middle connects to
the B: floppy.
2.8 Parallel port connector (CN3)
The parallel port is designated as LPT1, and is normally used to
connect the CPU card to a printer. The PCA-6740 includes an on-
board parallel port, accessed through a 26-pin flat-cable connector,
CN3. 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 connector.
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 CN3 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 CN3. Pin 1 is on the
right side of CN3.
