PCI-6872 User’s Manual 16
2.11 Printer port connector (CN4)
Normally, the parallel port is used to connect the card to a printer. The
PCI-6872 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN4 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 parallel port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
2.12 CompactFlash Card connector
The PCI-6872 provides a 50-pin socket for CompactFlash card type I/II.
2.12.1 CompactFlash (CN5)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
