1.1 Introduction
The PCA-6751/6751V is a half-size ISA-bus CPU card designed with
an on-board Intel Pentium®MMX CPU. Featuring powerful on-board
functions such as VGA, LCD, LAN and SSD, the versatile
PCA-6751/6751V can meet the needs of different applications.
Embedded Pentium®MMX CPU
The PCA-6751/6751V is equipped with Intel's new embedded
Pentium®MMX CPU at 166 MHz and 266 MHz. The CPU provides
high performance with low power consumption and better thermal
management, which is ideal for POS terminals, ATMs, and industrial
and embedded applications
Guaranteed long product supply time
In addition to the CPU, all the major components of the
PCA-6751/6751V are Intel EMD solutions. These include the 430 TX
system chipset, C&T69000 VGA/LCD controller and SB82558
10/100 Base-T Ethernet. Unlike regular commercial solutions, Intel
EMD solutions provide higher system stability and longer product
supply time (Intel EMD products' typical life cycle is 5 years). This
guarantee is particularly important for end systems that will last for
years.

1.4 Safety Precautions
Follow these simple precautions to protect yourself from harm and your
PC from damage.
1. To avoid electric shock, always disconnect the power from your PC
chassis before you work on it. Don't touch any components on the
CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may
damage sensitive electronic components.
3. Always ground yourself to remove any static charge before you touch
your CPU card. Be particularly careful not to touch the chip connectors.
Modern integrated electronic devices, especially CPUs and memory
chips, are extremely sensitive to static electric discharges and fields. Keep
the card in its antistatic packaging when it is not installed in the PC, and
place it on a static dissipative mat when you are working with it. Wear a
grounding wrist strap for continuous protection.

Chapter 1 Hardware Configuration 7
1.5 Jumper Settings
This section tells how to set the jumpers to configure your card. It
gives the card default configuration and your options for each jumper.
After you set the jumpers and install the card, you will also need to run
the BIOS Setup program (discussed in Chapter 3) to configure the serial
port addresses, floppy/hard disk drive types and system operating
parameters. Connections, such as hard disk cables, appear in Chapter 2.
For the locations of each jumper, see the board layout diagram depicted
earlier in this chapter.
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal cap (often protected by a
plastic cover) that slides over the pins to connect them. To "close" a
jumper you connect the pins with the cap. To "open" a jumper you
remove the cap. Sometimes a jumper will have three pins, labeled 1, 2
and 3. In this case you connect either pins 1 and 2 or 2 and 3.
You may find a pair of needle-nose pliers useful for setting the 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.
