2.19 FDD connector (CN14)
You can attach up to two floppy disk drives to the PCM-9340'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.
2.20 Parallel port connector (CN18)
The parallel port is designated as LPT1, and is normally used to connect
the CPU card to a printer. The PCM-9340 includes an on-board parallel
port, accessed through a 26-pin flat-cable connector, CN18. The card
comes with an adapter cable which lets you use a traditional DB-25 con-
nector. The cable has a 26-pin connector on one end and a DB-25 connec-
tor 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.
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 CN18 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 CN18. Pin 1 is on the right side of
CN18.
2.21 General Purpose Input Output (CN20)
The PCM-9340 supports 8-bit GPIO through CN20. The 8 digital in- and
out-puts can be programmed to read or control devices, with input or out-
put defined. The default setting is 4 bits input and 4 bits output.
