422/485), one multi-mode parallel (ECP/EPP/SPP) port, two USB (Universal Serial Bus) ports, a floppy drive controller, and a keyboard/PS/2
mouse interface. The built-in high-speed PCI IDE controller supports
both PIO and UDMA/100 bus master modes. Up to four IDE devices can
be connected, including large hard disks, CD-ROM drives, and tape
backup drives.
The PCM-9575 features power management to minimize power consumption. It complies with the “Green Function” standard and supports
Doze, Standby and Suspend modes. In addition, the board‘s watchdog
timer can automatically reset the system or generate an interrupt if the
system stops due to a program bug or EMI.
Highly integrated multimedia SBC
The PCM-9575 is a highly integrated multimedia SBC that combines
audio, video, and network functions on a single computer board the size
of a 5.25" floppy drive. It provides 16-bit half-duplex, 8-bit full-duplex,
integrated 3D audio, and up to 1024 x 768 resolution @ 16.8 M colors
with 8/16/32MB system memory. Major on-board devices adopt PCI
technology, to achieve outstanding computing performance when used
with Intel® Pentium® processors. The PCM-9575 also supports TV-out
that supports NTSC/PAL format for multimedia applications.

2.5 Setting Jumpers
You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric circuit. It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To “close” a
jumper, you connect the pins with the clip. To “open” a jumper, you
remove the clip. Sometimes a jumper will have three pins, labeled 1, 2
and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
open closed closed 2-3
The jumper settings are schematically depicted in this manual as follows:.
open closed closed 2-3
A pair of needle-nose pliers may be helpful when working with jumpers.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative before
you make any changes.
Generally, you simply need a standard cable to make most connections.
PCM-9575 User’s Manual 12
2.6 Clear CMOS (JP4)
Warning! To avoid damaging the computer, always turn
off the power supply before setting “Clear
CMOS.” Before turning on the power supply,
set the jumper back to “3.0 V Battery On.”
This jumper is used to erase CMOS data and reset system BIOS information.
The procedure for clearing CMOS is:
1. Turn off the system.
2. Short pin 2 and pin 3.
3. Return jumper to pins 1 and 2.
4. Turn on the system. The BIOS is now reset to its default setting

13 Chapter 2 Installation
2.7 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin density.
1. Make sure that the two handles of the DIMM socket are in the
“open” position. i.e. The handles remain leaning outward.
2. Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
3. Press the DIMM module right down into the socket, until you hear
a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.
To remove the memory module, just push both handles outward, and the

The PCM-9575 provides 2 IDE channels which you can attach up to four
Enhanced Integrated Device Electronics hard disk drives or CDROM to
the PCM-9575’s internal controller. The PCM-9575's IDE controller uses
a PCI interface. This advanced IDE controller supports faster data transfer, PID mode 3, mode 4 and UDMA/100. The secondary channel supports UDMA/33 only.
2.8.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one of two
cables (not included in this package), depending on the drive size. 1.8"
and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connector.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1. Connect one end of the cable to CN14 or CN16. 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.
PCM-9575 User’s Manual 14
(See your hard drive’s documentation 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.
2.9 Solid State Disk
The PCM-9575 provides a CompactFlash™ card socket and DiskOnChip
socket for Solid state disk solutions.
2.9.1 CompactFlash (CN26)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
2.10 Floppy drive connector (CN18)
You can attach up to two floppy drives to the PCM-9575’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.
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).
2.10.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN18. 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.
3. If you are connecting a 5.25” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connector.
15 Chapter 2 Installation
If you are connecting a 3.5” floppy drive, you may have trouble determining which pin is number one. Look for a number printed on the circuit
board indicating pin number one. In addition, the connector on the floppy
drive may have a slot. When the slot is up, pin number one should be on
the right. Check the documentation that came with the drive for more
information.
If you desire, connect the B: drive to the connectors in the middle of the
cable as described above.
In case you need to make your own cable, you can find the pin assignments for the board’s connector in Appendix C.
2.11 Parallel port connector (CN15)
Normally, the parallel port is used to connect the card to a printer. The
PCM-9575 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN15 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 Keyboard and PS/2 mouse connector (CN25)
The PCM-9575 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 selftest (POST) after a reset. The PCM-9575’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.
