Introduction
The PCM-4824 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 by taking only a tiny space
area as that of a 3 1/2" hard drive. Supporting high-performance
486 processors from 486DX up to 486DX4-120 CPUs including
5x86 CPUs, the PCM-4824 comes with a 4-channel TTL level
compatible digital I/O feature that allows for a complete process-
ing system. For maximum performance, the PCM-4824 also
supports an 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-232 and RS-232/422/485) with DB-9 connector as COM1, a
mini-DIN PS/2 keyboard/mouse interface. A local bus SVGA/
LCD display controller (LCD, EL and CRT displays) allows LCD
screen resolutions up to 640 x 480 x 256 colors and CRT
resolutions up to 1024 x 768 x 16 colors.
The PCM-4824 complies with the "Green Function" standard and
supports five types of power saving features: Normal, Conserve,
Doze, Sleep, and Suspend 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-4824 has an on-
board expansion bus connector for future upgrades.

Installation
This chapter tells how to set up the PCM-4824
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 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 electri-
cal 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! 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.
Installing the CPU
The PCM-4824 all-in-one SBC supports most 486 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 follow-
ing 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-4824User'sManual
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.
Improper settings may damage the CPU.
