15 Chapter 2 Installation
2.12 Printer port Connector (CN3)
Normally, the printer port is used to connect the card to a printer. The
PCI-6881 includes a multi-mode (SPP/EPP/ECP) printer port accessed
via CN3 and a 26-pin flat-cable connector. You will need an adapter cable
if you use a traditional DB-25 connector. The adapter cable has a 26-pin
connector on one end, and a DB-25 connector on the other.
The printer port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The printer port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
2.13 CompactFlash Socket
The PCI-6881 provides a 50-pin socket for CompactFlash card type I/II.
2.13.1 CompactFlash (CN20)
The CompactFlash card occupies a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
2.14 Floppy Connector (CN2)
You can attach up to two floppy drives to the PCI-6881’s on-board con-
troller. 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.
A 34-pin daisy-chain drive connector cable is required for a dual-drive
system. 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).
2.14.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN2. Make sure that the
red wire corresponds to pin one on the connector.
2. Attach the appropriate connector on the other end of the cable to
the floppy drive(s). You can use only one connector in the set. The
set on the end (after the twist in the cable) connects to the A: drive.
The set in the middle connects to the B: drive.
