Introduction
The PCM-4822 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, taking no more space than a
3 1/2" hard drive. An integrated 16-bit Ethernet interface and
4-channelTTL levelcompatible digitalI/O makesthe PCM-4822a
complete processing system. High-performance 486 processors
from486DX upto 486DX4-120CPUsand 5x86CPUs aresupported.
Formaximum performance,the PCM-4822also supportsan EDO/
Normal DRAM SIMM socket that can take up to 32MB memory.
On-board features include support for VL-Bus Enhanced IDE
interface with up to Mode 3 transfer protocol, two serial ports (RS-
232and RS-232/422/485)withDB-9 connectorasCOM1, amini-DIN
PS/2 keyboard/mouse interface.
The PCM-4822 complies with the "Green Function" standard and
supports five types of power saving features: Normal, Conserve,
Doze, Sleep, and Suspend modes.
If you need any additional functions, the PCM-4822 has an on-
board expansion bus connector for future upgrades.

Installation
This chapter tells how to set up the PCM-4822
hardware, including instructions on setting
jumpers and connecting peripherals, switches
and indicators. Be sure to read all the safety
precautions before you begin the installation
procedure.

Jumpers and connectors
Connectors on the board link it to external devices such as hard
disk drives, a keyboard or an expansion bus connector. In addition,
the board has a number of jumpers that allow you to configure your
system to suit your application.
The table below lists the function of each of the board jumpers and
connectors:

Setting jumpers
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.
The jumper settings are schematically depicted in this manual as
follows:
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 connec-
tions.

Safety precautions
Warning! Alwayscompletelydisconnect the power cordfrom
yourboardwheneveryou are working on it.Donot
make connections while the power is on because
sensitiveelectronic components canbe damaged
bythe sudden rushof power.
Caution! Alwaysgroundyourself to remove anystatic
chargebeforetouching the board. Modernelec-
tronic 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.
Installing the CPU
ThePCM-4822 all-in-one SBCsupports most486 CPUs.The
system's performance depends on the CPU you choose. You can
install or upgrade the CPU in the board's PGA socket by following
the procedures outlined below. If your system has an existing CPU,
you need to remove it before installing the new CPU.
Removing a CPU
1. Disconnect power and unplug all connections to the board.
2. Lift the CPU out of the PGA socket. The old chip may be
difficult to remove. You may find spray chip lubricant, designed
for pin-grid-array (PGA) devices, and a chip puller helpful.
These are available at electronics hobbyists' supply stores.

14 PCM-4822 User's Manual
Installing a CPU
To install the CPU, follow the instructions that came with it. If no
documentation was provided, the general procedures for installing
a CPU are outlined below:
1. Lubricate the pins on the CPU with lubricant for PGA devices.
This makes the CPU slide in much easier and greatly reduces
the chance of damaging the pins and other components.
2. Carefully align the CPU so that it is parallel to the socket. Make
sure that the notch on the corner of the CPU matches the notch
on the inside of the socket.
3. Gently push the CPU into the socket. There will probably be a
small gap between the CPU and the socket even when it is fully
seated.DONOTUSEEXCESSIVEFORCE!
When you install a new CPU, you may have to adjust other
settings on the board, such as CPU type and CPU clock to accom-
modate it. Make sure that the settings are correct for your CPU.
