2.3 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 connec-

tor 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.

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.

2.5 Keyboard & PS/2 mouse connectors (J5)

The PCA-6145B/PCA-6145L board provides a keyboard connector. A 6-

pin mini-DIN connector (J5) on the card mounting bracket supports sin-

gle-board computer applications. The card comes with an adapter to con-

vert from the 6-pin mini-DIN connector to a standard DIN connector and

to a PS/2 mouse connector.
