General Information
This chapter gives background informa-
tion on the PCM-3345.
Sections include:
• Board specifications
• Board layout and dimensions

2PCM-3345 User's Manual
1.1 Introduction
The PCM-3345 is the ultimate cost-effective PC/104 solution for
limited-space applications. It offers all the functions of an
AT-compatible industrial computer on a single board, and occupies
less space than a 3½" hard drive. The PCM-3345 comes with an
embedded STPC Client processor on-board. For maximum perfor-
mance, the PCM-3345 also supports an EDO/FPM SODIMM socket
that can accept up to 32 MB memory.
On-board features include a socket for a CompactFlash Card, En-
hanced IDE interface, one parallel port, two serial ports (RS-232), a
keyboard, and a PS/2 mouse interface. An SVGA display controller
allows CRT resolutions up to 1024 x 768 @ 64 K colors.
The PCM-3345 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 minimiz-
es 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-3345 has a PC/104
connector for future upgrades.

Installation
This chapter tells how to set up the
PCM-3345 hardware. It includes instruc-
tions on setting jumpers and connecting
peripherals, switches and indicators.
Make sure you read all the safety precau-
tions before you begin the installation
procedure.

2.3 Locating connectors
Warning: Please note there are two different kinds of compo-
nent sides: one for PCM-3345 Rev A1, and one for
PCM-3345 Rev A2. Rev A1 and Rev A2 have
different voltages at CN9 and CN10.
Make sure you use the correct component side.
Improper installation can cause serious damage to
your hardware!

2.4 Setting jumpers
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
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 representative
before you make any changes.
Generally, you simply need a standard cable to make most connec-
tions.
