 This device complies with the requirements in part
15 of the FCC rules: Operation is subject to the fol-
lowing two conditions:
1.This device may not cause harmful interference,
and
2.This device must accept any interference
received, including interference that may cause
undesired operation
This equipment has been tested and found to com-
ply with the limits for a Class A digital device, pursu-
ant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference when the equipment is oper-
ated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance
with the instruction manual, may cause harmful
interference to radio communications. Operation of
this device in a residential area is likely to cause
harmful interference in which case the user will be
required to correct the interference at his/her own
expense. The user is advised that any equipment
changes or modifications not expressly approved
by the party responsible for compliance would void
the compliance to FCC regulations and therefore,
the user's authority to operate the equipment.

Caution! There is a danger of a new battery exploding if it is

incorrectly installed. Do not attempt to recharge,
force open, or heat the battery. Replace the battery
only with the same or equivalent type recom-
Achtung! mended by the manufacturer. Discard used batter-
ies according to the manufacturer’s instructions

ing equipment. PCM-9375 is ideal for communication, gaming and medical
applications that require flat panel support using digital displays with TTL
or LVDS interfaces and two Ethernet ports.
For those who want superior performance for various low-power embed-
ded applications, PCM-9375 uses an AMD LX-800 processor clocked at
500 MHz, in conjunction with flexible DDR333 system memory through
one SODIMM socket.
PCM-9375 offers convenient connector layout, easy assembly, multiple
I/O, and includes two 10/100Mbps Ethernet, four USB (Universal Serial
Bus) 2.0 and four serial ports for easy system expansibility.

2.4 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 cir-
cuit. 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.

using 200-pin SODIMMs (Small Outline Dual In-line Memory Modules).
1. Ensure that all power supplies to the system are switched off.
2. Tilt the SODIMM card approximately 25° above the board, and
move it in the direction of the housing card slot. Make sure that the
key in the module and the key in the housing are aligned.
3. Push the module into the socket until the module bottoms. There
should be a slight insertion force to engage the module into the con-
tacts.

mode 4 and up to UDMA33.
2.6.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. This package includes
One 44PIN 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 documentation for the location of the con-
nector.)

2.7 Solid State Disk

The board provides a CompactFlash™ card type I socket and type II for

Normally, the parallel port is used to connect the card to a printer. The
board includes a multi-mode (ECP/EPP) parallel port accessed via CN17
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 connec-
tor 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.

tions, 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 board’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 sys-
tem halting under POST.

CHAPTER
PCI SVGA/LCD Setup
This chapter details the software con-
figuration information. It shows you
how to configure the card to match
your application requirements. The
AWARD System BIOS is covered in
Chapter 4.
Sections include:

• Installation of SVGA drivers

- for Window XP
• Connections for standard LCDs
• Further information
Chapter 4 PCI SVGA/LCD Setup
4.1 Introduction

PCM-9375 has an onboard AMD Geode LX800 chipset for its AGP/
SVGA controller. It supports TFT LCD displays and conventional analog
CRT monitors with 64 MB frame buffer shared with system memory. The
VGA controller can drive CRT displays with resolutions up to 1600 x
1200 x 16 bpp at 100 Hz and up to 1024 x 768 x 32 bpp at 60 Hz for TFT
LCD.
4.1.1 Display type
The board can be set in one of three configurations: on a CRT, on a flat
panel display, or dual simultaneous display. The system is initially set to
dual display mode. If you want to enable the CRT display only or the flat
panel display only, please set them up from the BIOS screen, or contact
Advantech’s technical support center.
4.1.2 Dual Simultaneous Display
The board uses an AMD LX800 controller that is capable of providing
multiple views and simultaneous display with mixed video and graphics
on a flat panel and CRT. The Dual display can be set up by CMOS set-
ting.
4.1.3 CMOS setting for panel type
The board system BIOS and custom drivers are located in a 512 KB,
Flash ROM device. A single Flash chip holds the system BIOS, VGA
BIOS and network Boot ROM image. The display can be configured via
CMOS settings, please choose "panel type" from the "Advanced Chipset
Features" menu in the CMOS settings.
