Chapter 2 Installation
2.6 IDE, CDROM Hard Drive Connector (CN11)
The board provides 1 IDE channel which you can attach up to two Enhanced Inte-
grated Drive Electronics hard disk drives or CDROM to the board’s internal controller.
Its IDE controller uses a PCI interface. This advanced IDE controller supports faster
data transfer, PIO mode 3, mode 4 and up to UDMA 33/66.
2.6.1 Connecting the Hard Drive
Connecting drives is done in a daisy-chain fashion. This package includes One 44
PIN IDE cable that can connect to 1.8" and 2.5" drives.
1. Connect one end of the cable to Hard Drive connector. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector, which is labeled on the
board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on
the cable corresponding to pin 1 on the hard drive. (See your hard drive’s docu-
mentation for the location of the connector.)
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you
install two drives, you will need to set one as the master and one as the slave by
using jumpers on the drives. If you install only one drive, set it as the master.
2.7 Solid State Disk
The board provides a CompactFlash card type I socket and type II for optional kit.
2.7.1 Compact Flash (CN41)
The CompactFlash card shares a secondary IDE channel which can be enabled/dis-
abled via the BIOS settings.
2.8 Parallel Port Connector (CN19)
Normally, the parallel port is used to connect the cable to a printer. The board
includes a multi-mode (ECP/EPP) parallel port accessed via CN19 and a 26-pin flat-
cable connector. You will need an adapter cable if you use a traditional DB-25 con-
nector. The adapter cable has a 26-pin connector on one end, and a DB-25 connec-
tor 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/ECP DMA channel via BIOS setup.
2.9 Keyboard and PS/2 Mouse Connector (CN18)
The board provides a keyboard connector that supports both a keyboard and a PS/2
style mouse. In most cases, especially in embedded applications, a keyboard is not
used. If the keyboard is not present, the standard PC/AT BIOS will report an error or
fail during power-on self-test (POST) after a reset. The PCM 3353’s BIOS standard
setup menu allows you to select “All, But Keyboard” under the “Halt On” selection.
This allows no-keyboard operation in embedded system applications, without the
system halting under POST.
