18 PCA-6145B/6145L User's Manual
Floppy drive connector (CN3)
You can attach up to two floppy disk drives to the PCA-6145B/
PCA-6145L's on-board controller. You can use any combination of
5.25"
(360 KB and 1.2 MB) and/or 3.5" (720 KB, 1.44 MB and 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.
Parallel port connector (CN4)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6145B/PCA-6145L includes an on-board parallel
port, accessed through a 26-pin flat-cable connector, CN4. 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 CN4 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
CN4. Pin 1 is on the right side of CN4.
