CHAPTER

General Information
This chapter gives background information 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 transmission 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 application 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.

The jumper settings are schematically depicted in this manual as

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.

2.5 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.

You can install anywhere from 16 MB to 128 MB of on-board
DRAM memory using 16, 32, 64 or 128 MB 144-pin SODIMMs
(Small Outline Dual In-line Memory Modules).
2.6.2 Installing SODIMMs
Note: The modules can only fit into a socket one way
and their gold pins must point down into the
SODIMM socket.
The procedure for installing SODIMMs appears below. Please
follow these steps carefully.
1. Ensure that all power supplies to the system are switched Off.
2. Install the SODIMM card. Install the SODIMM so that its gold
pins point down into the SODIMM socket.
3. Slip the SODIMM into the socket at a 45 degree angle and
carefully fit the bottom of the card against the connectors.
4. Gently push the SODIMM into a perpendicular position until
the clips on the ends of the SODIMM sockets snap into place.
5. Check to ensure that the SODIMM is correctly seated and all
connector contacts touch. The SODIMM should not move
around in its socket.

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.

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 CompactFlash 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 dualdrive 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.
