Chapter 1 Introduction

1.1 Introduction

The PCM-9372 is a VIA low-power Eden processor single board com­puter (SBC) with audio controller, a 4X AGP SVGA controller, a PCI 10/
100Base-T Ethernet interface, 2 Channel LVDS interface, and one PC/
104 expansion connector. The PCM-9372’s design is based on the 3.5"
HDD form factor that provides a convenient connector layout for easy
assembly, more efficient cable connections and better overall embedded
system integration. When using a VIA Eden processor, the PCM-9372
achieves outstanding performance that surpasses most SBCs in its class.
This compact (only 5.7" x 4") unit offers all the functions of a single
board industrial computer, but still fits in the space of a 3.5" floppy drive.
On-board features include, two serial ports (one RS-232, one RS-232/
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-9372 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.

1.1.1 Highly integrated multimedia SBC

The real estate is well-packed on this tightly designed 3.5" single board
computer (SBC) with an onboard new VIA Embedded low power Eden
processor. The VIA Eden processor uses advanced 0.15µ/0.13µ CMOS
technology with 128KB L1 cache memory and 64KB L2 cache memory
on die. This board can operate without a fan at temperatures up to 60× C
(140× F) and typically consumes under 12 Watts while supporting numer­ous peripherals. This SBC includes a 4X AGP controller, an AC'97 audio
interface, a PCI Ethernet interface, and 2 channel LVDS interface. Its
design is based on the 3.5" SBC form factor that supports the PC/104
interface for ISA module upgrades. Other on-board features include an
LPT, 2 USBs, and 2 serial ports: 1 RS-232, and 1 RS-232/422/485. The
SSD solution supports CompactFlash™ cards Type I and Type II.

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.

2.6 Clear CMOS (S2)

Warning!

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

Table 2.3: CMOS clear (S2)

* default setting

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.”

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
module will be ejected from the socket.

2.8 IDE, CDROM hard drive connector (CN13)

The PCM-9372 provides 1 IDE channels which you can attach up to two
Enhanced Integrated Device Electronics hard disk drives or CDROM to
the PCM-9372’s internal controller. The PCM-9372's IDE controller uses
a PCI interface. This advanced IDE controller supports faster data trans­fer, PID mode 3, mode 4 and up to UDMA/100.

2.8.1 Connecting the hard drive

Connecting drives is done in a daisy-chain fashion. This package includes
1 40PIN IDE cable that can connect to 3.5"HDD and CD ROM device.

1.8" and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector

(p/n: 1701440500).

1. Connect one end of the cable to CN13. 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 documentation for the location of the con-

nector.)
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-9372 provides a CompactFlash™ card socket and DiskOnChip
socket for Solid state disk solutions.

2.9.1 CompactFlash (CN21)

The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.

2.10 Floppy drive connector (CN20)

You can attach up to two floppy drives to the PCM-9372’s on-board con­troller. You can use 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).

2.10.1 Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into CN20. 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.
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 (CN19)

Normally, the parallel port is used to connect the card to a printer. The
PCM-9372 includes a multi-mode (ECP/EPP/SPP) 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 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 (CN12)

The PCM-9372 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-9372’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.

2.13 Power & HDD LED, Reset Button Connector (CN11, S1)

Next, you may want to install external switches to monitor and control the
PCM-9372. These features are optional: install them only if you need
them. The Power & HDD LED connector (CN11) is 6-pin Wafer box con­nector. It provides connections for a power and hard disk access indicator.
