General Information
This chapter gives background informa-
tion on the PCM-5820 Series.
Sections include:
• Board specifications
• Board layout and dimensions
1.1 Introduction
The PCM-5820 Series is the ultimate cost-effective solution for
limited space applications. It offers all the functions of an
AT-compatible industrial computer on a single board and only
occupies the space of a 3½" hard drive. The PCM-5820/5820L
comes with an embedded high-performance GXM-233 processor
on-board. The PCM-5820E and PCM-5822 come with a low
power GXM-200 processor on-board. For maximum performance,
the PCM-5820 Series also support an SDRAM SODIMM socket
that can accept up to 128 MB memory.
On-board features include an Ethernet interface, audio interface,
socket for Compact Flash Card, Enhanced IDE interface with up to
Ultra DMA transfer protocol, one parallel port, two serial ports
(RS-232 and RS-232/422/485) with DB-9 connector as COM1,
and a mini-DIN PS/2 keyboard/mouse interface. An SVGA/LCD
display controller (LCD, and CRT displays) allows LCD screen
resolutions up to 1024 x 768 and CRT resolutions up to 1280 x
1024 @ 16 colors. Supports LVDS interface (PCM-5820L and
PCM-5820E only) for long distance LCD panel signal transmis-
sion and EMI protection add-ons. Also provided is a TV-out
function (PCM-5822 only) for NTSC and PAL TV format that
supports composite, S-video and SCART (optional) outputs.
The PCM-5820 Series complies with the "Green Function"
standard and supports three types of power saving features:
Normal, Doze, and Sleep modes.
The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This
minimizes the number of chips and eases configuration. You can
change the display BIOS simply by programming the Flash chip.
If you need any additional functions, the PCM-5820 Series has a
PC/104 connector for future upgrades.

2.4 Setting jumpers
2.4.1 Introduction
You may configure your card to match the needs of your applica-
tion by setting jumpers. A jumper is the simplest kind of electrical
switch. 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.

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 representa-
tive before you make any changes.
Generally, you simply need a standard cable to make most
connections.

2.5 Safety precautions
Warning! Always completely disconnect the power cord
from your board whenever you are working on it.
Do not make connections while the power is on
because sensitive electronic components can be
damaged by the sudden rush of power.
Caution! Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.

2.7 IDE hard drive connector (CN11)
The built-in Enhanced IDE (Integrated Device Electronics)
controller supports up to two IDE devices, including CD-ROM
drives, tape backup drives, a large hard disk drive and other IDE
devices. It also supports faster data transfer, PIO mode 3, mode 4,
and Ultra DMA 33 mode.
2.7.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion and requires
one or two cables, depending on the drive size. All required cables
are included in your PCM-5820 Series package. 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. However, the
required connectors are not included in the PCM-5820 Series
package.
Wire number 1 on the cable is red or blue, and the other wires are
gray.
1. Connect one end of the cable to CN11. 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 to 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 connector.)
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 just one drive, set it as the master.
Chapter 2 Installation

2.8 CompactFlash™ disk (CN19)
The PCM-5820 Series is equipped with a CompactFlash disk
socket on the solder side and it supports the IDE interface Com-
pactFlash disk card. The socket itself is especially designed to
prevent any incorrect installation of the CompactFlash disk card.
When installing or removing the CompactFlash disk card, please
make sure that the system power is off.
The CompactFlash disk card is defaulted as the E: disk drive in
your PC system.
2.9 Floppy drive connector (CN2)
You can attach up to two floppy drives to the the PCM-5820
Series' on-board controller. Any combination of 5¼” (360 KB and
1.2 MB) and/or 3½” (720 KB, 1.44 MB, and 2.88 MB) drives is
possible.
A 34-pin daisy-chain drive connector cable is required for a dual-
drive system. A 34-pin flat-cable connector is fitted on one end of
the cable while the other end sports two sets of floppy disk drive
connectors. Each set consists of a 34-pin flat-cable connector (for
the 3½” drives) and a printed-circuit board connector (for the 5¼”
drives).
2.9.1 Connecting the floppy drive
1. Plug in the 34-pin flat-cable connector into CN2. Make sure
that the red wire corresponds to pin 1 on the connector.
2. Attach the appropriate conector at the other end of the cable to
the floppy drive(s). You can use only one connector in the set.
The set at the other 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 5¼” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
20
PCM-5820 Series User's Manual
When connecting a 3½” floppy drive, you may have some
difficulties in determining which pin is pin number one. Look for a
number on the circuit board indicating pin number one. In addi-
tion, you should check if the connector on the floppy drive has an
extra slot. If the slot is up, pin number one should be on the right.
Please refer to any documentation that came with the drive for
more information.
If needed, connect the B: drive to the connectors in the middle of
the cable as described as above.
If your cable needs to be custom made, you can find the pin
assignments for the board's connector in Appendix A.
2.10 Parallel port connector (CN3)
Normally, the parallel port is used to connect the card to a printer.
The PCM-5820 Series includes a multi-mode (ECP/EPP/SPP)
parallel port, accessed through CN3 - a 26-pin flat-cable connec-
tor.
You will need an adapter cable if you use a traditional DB-25
connector. The adpater cable should have a 26-pin connector on
one end and a 25-DB 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 as IRQ7.
The proper ECP/EPP DMA channel can be selected via the BIOS
setup.

appear on the screen along with the following instructions:
press <F1> to RESUME
Write down the message and press the F1 key to continue the bootup
sequence.
4.1.1 System configuration verification
These routines check the current system configuration against the
values stored in the board’s CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.
There are three situations in which you will need to change the CMOS
settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration informa-
tion has been erased.
The PCM-5820 Series' CMOS memory has an integral lithium battery
backup. The battery backup should last ten years in normal service,
but when it finally runs down, you will need to replace the complete

Windows 95/98/NT
5.1 Introduction
The PCM-5820 Series has an on-board LCD/VGA interface. The
specifications and features are described as follows:
5.1.1 Chipset
The PCM-5820 Series uses a Cyrix CX5530 chipset for its SVGA
controller. It supports many popular 18-bit LCD displays and conven-
tional analog CRT monitors. The VGA BIOS supports LCD. In
addition, it also supports interlaced and non-interlaced analog moni-
tors (color and monochrome VGA) in high-resolution modes while
maintaining complete IBM VGA compatibility. Digital monitors (i.e.
MDA, CGA, and EGA) are NOT supported. Multiple frequency
(multisync) monitors are handled as if they were analog monitors.
5.1.2 Display memory
With 2 ~ 5 MB share memory, the VGA controller can drive CRT
displays or color panel displays with resolutions up to 1024 x 768 at
64 K colors. The display memory can be expanded to 4 MB in BIOS
for true-color resolution of 1024 x 768.

Windows 95/98/NT
7.1 Introduction
The PCM-5820 Series is equipped with a high performance 32-bit
Ethernet chipset which is fully compliant with IEEE 802.3 100 Mbps
CSMA/CD standards. It is supported by major network operating
systems. It is also both 100Base-T and 10Base-T compatible. The
medium type can be configured via the RSET8139.exe program
included on the utility disk.
The Ethernet port provides a standard RJ-45 jack on board. The
network boot feature can be utilized by incorporating the boot ROM
image files for the appropriate network operating system. The boot
ROM BIOS files are combined with system BIOS, which can be
enabled/disabled in the BIOS setup.
7.2 Installation of Ethernet driver
Before installing the Ethernet driver, note the procedures below. You
must know which operating system you are using in your PCM-5820
Series, and then refer to the corresponding installation flow chart.

Installing PC/104
Modules
This appendix gives instructions for
installing PC/104 modules.
D.1 Installing PC/104 modules
The PCM-5820 Series' PC/104 connectors give you the flexibility
to attach PC/104 modules.
Installing these modules on the PCM-5820 Series is quick and simple.
The following steps show how to mount the PC/104 modules:
1. Remove the PCM-5820 Series from your system, paying
particular attention to the safety instructions already mentioned
above.
2. Make any jumper or link changes required to the CPU card
now. Once the PC/104 module is mounted you may have
difficulty in accessing these.
3. Normal PC/104 modules have male connectors and mount
directly onto the main card. (Refer to the diagram on the
following page.)
4. Mount the PC/104 module onto the CPU card by pressing the
module firmly but carefully onto the mounting connectors.
5. Secure the PC/104 module onto the CPU card using the four
mounting spacers and screws.

Programming the
Watchdog Timer
The PCM-5820 Series is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for whatever reason. This
feature ensures system reliability in
industrial standalone or unmanned
environments.
E.1 Programming the watchdog timer
Jumper J3 controls the watchdog settings. The default configura-
tion of the timer is enabled via a system reset.
To enable the watchdog timer, you must write a program which
writes 1 to I/O port address 443 (hex) at regular intervals. The first
time your program reads the port, it enables the watchdog timer.
After that, your program must write 1 to the port at time interval of
less than 1.6 seconds, otherwise the watchdog timer will activate
and reset the CPU or generate an interrupt on IRQ11. When you
want to disable the watchdog timer, your program should write 0
to I/O port 443.
If CPU processing comes to a standstill because of EMI or a
software bug, your program's signals to I/O port 443 to the timer
will be interrupted. The timer will then automatically reset the
CPU or invoke an IRQ, and data processing will continue normal-
ly.
You must write your program so that it writes 1 to I/O port 443 at
an interval shorter than the timer's preset interval. The timer's
intervals have a tolerance of ± 30%, so you should program an
instruction that will refresh the timer about every second.
