CHAPTER

2PCM-4825/4825L User's Manual
1.1 Introduction
The PCM-4825/4825L 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 occu-
pies the space of a 3 1/2" hard drive. The PCM-4825/4825L
comes with an embedded high-performance 5x86 processor and
audio on-board. For maximum performance, the PCM-4825/
4825L also supports an EDO/FPM DRAM SIMM socket that can
accept up to 32 MB memory.
On-board features include a 16-bit audio controller (PCM-4825
only), support for a VL-Bus Enhanced IDE interface with up to
Mode 3 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. A local bus SVGA/
LCD display controller (LCD, EL and CRT displays) allows LCD
screen resolutions up to 1024 x 768 and CRT resolutions up to
1280 x 1024 @ 16 colors.
The PCM-4825/4825L 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-4825/4825L has a
PC/104 connector for future upgrades.

Installation
This chapter tells how to set up the PCM-4825/
4825L hardware, including instructions on
setting jumpers and connecting peripherals,
switches and indicators. Be sure to read all the
safety precautions before you begin the installa-
tion procedure.

2.1 Jumpers and connectors
Connectors on the board link it to external devices such as hard
disk drives, a keyboard or expansion bus connectors. In addition,
the board has a number of jumpers that allow you to configure your
system to suit your application.

2.4 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.
