1.1 Introduction
The PCA-6751 Series is a half-size ISA-bus CPU card designed with
an onboard Intel® Pentium® MMX CPU. Featuring powerful onboard
functions such as VGA, LCD, LAN and SSD, the versatile PCA-6751
Series can meet the needs of different applications.

Embedded Pentium® MMX CPU

The PCA-6751 Series is equipped with Intel's new embedded Pen-
tium® MMX CPU at 166 MHz and 266 MHz. The CPU provides high
performance with low power consumption and better thermal manage-
ment, 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
Series are Intel® EMD solutions. These include the 430 TX system
chipset, C&T 69000/69030 VGA/LCD controller, and
SB82558/SB82559/RTL-8139 10/100Base-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. Do not 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 dissipa-
tive mat when you are working with it. Wear a grounding wrist
strap for continuous protection.

1.5 Jumper settings

1.5.1 Introduction
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 operat-
ing 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, connect the pins with the cap. To "open" a jumper, 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.

 1.5.6 Watchdog timer configuration (JP4)
An onboard watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu-
able protective device for standalone or unmanned applications. Setup
involves two jumpers and running the control software. (Refer to
Appendix A.)
When the watchdog timer is enabled and the CPU shuts down, the
watchdog timer will automatically either reset the system or generate
an interrupt on IRQ 11, depending on the setting of jumper JP4, as
shown below:

1.6 Installing system memory (SODIMMs)
You can install anywhere from 8 to 256 MB of SDRAM into your
PCA-6751 Series card. The card provides two 144-pin SODIMM
sockets. Each socket accepts 8, 16, 32, 64 or 128 MB 3.3 V power
level SODIMMs. If only one SODIMM module is installed, it may be
installed in either SODIMM socket on the solder side of the
PCA-6751 Series card.

Note: PCA-6751 Series cards only support SDRAM

SODIMM modules. EDO SODIMM is not supported.

1.6.1 Installing SODIMMs

Note: The modules can only fit into a socket one way.
Their gold pins must point down into the SODIMM
socket.

Programming the
Watchdog Timer
The PCA-6751 Series is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for any reason. This feature
ensures system reliability in industrial
standalone or unmanned environments.
A.1 Programming the watchdog timer
To program the watchdog timer, you must write a program which
writes I/O port address 443 (hex). The output data is a value of time
interval. The value range is from 01 (hex) to 3E (hex), and the related
time interval is 1 sec. to 62 sec.
Data Time Interval
01 1 sec.
02 2 sec.
03 3 sec.
04 4 sec.
• •
• •
• •
3E 62 sec.

70 PCA-6751 Series User's Manual

After data entry, your program must refresh the watchdog timer by
rewriting the I/O port 443 (hex) while simultaneously setting it. When
you want to disable the watchdog timer, your program should read I/O
port 443 (hex).
The following example shows how you might program the watchdog
timer in BASIC:
10 REM Watchdog timer example program
20 OUT &H443, data REM Start and restart the watchdog
30 GOSUB 1000 REM Your application task #1,
40 OUT &H443, data REM Reset the timer
50 GOSUB 2000 REM Your application task #2,
60 OUT &H443, data REM Reset the timer
70 X=INP (&H443) REM, Disable the watchdog timer
80 END

Installing PC/104
Modules
This appendix gives instructions for
installing PC/104 modules.
B.1 Installing PC/104 modules
The PCA-6751 Series' PC/104 connectors give you the flexibility to
attach PC/104 modules.
Installing these modules on the PCA-6751 Series is quick and simple.
The following steps show how to mount the PC/104 modules:
1. Remove the PCA-675 Series from your system paying particular
attention to the safety instructions already mentioned above.
2. Make any jumper or link changes required to the CPU card now.
Once the PC/104 module is mounted you may have difficulty in
accessing these.
3. Normal PC/104 modules have male connectors and mount directly
onto the main card. (Refer to the diagram on the following page.)
4. Mount the PC/104 module onto the CPU card by pressing the
module firmly but carefully onto the mounting connectors.
5. Secure the PC/104 module onto the CPU card using the four
mounting spacers and screws.

This appendix contains information on
Advantech's LCD lighting services.
E.1 LCD services
LCD screens are very popular on Advantech's CPU cards, Biscuit PCs
and POS Series products, such as the PCA-6135/6145/6153, and
PCA-6751 Series. "Lighting" LCDs is virtually impossible without
technical expertise. Advantech provides LCD lighting and integration
services to assist our customers in setting up their systems. Advan-
tech's LCD lighting guide explains how to make connections between
LCD interfaces and LCD panels, as well as how to control contrast,
brightness, VEE source, LCD inverter and all other factors that affect
the successful installation of LCD panels.
The following information details our LCD lighting services:
a) This policy is only valid for Advantech products that include LCD
support
b) The customer should send the following LCD components for
service:
• DC-AC inverter and cable (i.e. connector with/without wires)
and data sheet
• LCD flat panel and cable (connector with/without wires) and
complete data sheet
c) Advantech will normally charge the customer a deposit. The
deposit will be refunded when servicing exceeds a minimum
volume
d) The customer must sign the agreement and fax it to us prior to
sending the LCD package. Advantech reserves the right to refuse
service if the customer cannot provide the required documents and
auxiliary parts
e) Advantech will supply a BIOS file and connection cable to the
customer upon completing the service
f) A minimum of seven working days is required for completion of
service, starting from receipt of the LCD package by Advantech
