Product warranty
Advantech warrants to you, the original purchaser, that each of its prod-
ucts will be free from defects in materials and workmanship for two years
from the date of purchase.
This warranty does not apply to any products which have been repaired or
altered by persons other than repair personnel authorized by Advantech,
or which have been subject to misuse, abuse, accident or improper instal-
lation. Advantech assumes no liability under the terms of this warranty as
a consequence of such events.
If an Advantech product is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you will
be billed according to the cost of replacement materials, service time and
freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, type of PC, CPU speed, Advantech products used, other
hardware and software used, etc.) Note anything abnormal and list
any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your man-
ual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
material authorization) number from your dealer. This allows us to
process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for war-
ranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

Initial Inspection
Before you begin installing your card, please make sure that the following
materials have been shipped:
• PCA-6006 Pentium ® 4/Celeron™ processor-based single board com-
puter
• 1 PCA-6006 Startup Manual
• 1 CD with driver utility and manual (in PDF format)
• 1 FDD cable, P/N: 1700340640
• 2 Ultra ATA 100 HDD cables, P/N: 1701400452
• 1 printer (parallel port) cable & COM port cable kit, P/N: 1701260305
• 1 ivory cable for PS/2 keyboard and PS/2 mouse, P/N: 1700060202
• 1 USB cable adapter, P/N: 1700100170 (optional)
If any of these items are missing or damaged, contact your distributor or
sales representative immediately.
We have carefully inspected the PCA-6006 mechanically and
electrically before shipment. It should be free of marks and scratches and
in perfect working order upon receipt.
As you unpack the PCA-6006, check it for signs of shipping damage.
(For example, damaged box, scratches, dents, etc.) If it is damaged or it
fails to meet the specifications, notify our service department or your
local sales representative immediately. Also notify the carrier. Retain the
shipping carton and packing material for inspection by the carrier. After
inspection, we will make arrangements to repair or replace the unit.

PCA-6006 User’s Manual 2
Chapter 1 Hardware Configuration
1.1 Introduction
Advantech's PCA-6006 full-size CPU card is designed with Intel 845GV
chipset and supports socket 478 Pentium 4/Celeron processor (FSB 400/
533MHz) up to 3.06GHz and above. In addition to high-speed processor,
PCA-6006 supports up to 2GB DDR memory with 2 DIMM socket on
board. It provides maximum computing power and productivity which is
ideal for high-performance demanding application. Intel®'s 845GV inte-
grated VGA provides superior 3D performance with unique Intel®
Extreme Graphics architecture. Intel 82562 10/100Base-T Ethernet con-
troller is available in PCA-6006 series. The high reliability and excellent
performance provided by Intel Ethernet controller are crucial for various
network applications. PCA-6006 also offers an exclusive feature of USB
2.0 and which provides high speed data transfer rate up to 480 Mb/sec. In
addition to onboard two USB connectors, flexible I/O expension board
allows customer to optimize their need for additional four USB port.
A backup of CMOS data is stored in the Flash memory, which protects
data even after a battery failure. Also included is a 255-level watchdog
timer, which resets the CPU or generates an interrupt if a program cannot
be executed normally. This enables reliable operation in unattended envi-
ronments..
Note: Some of the features mentioned above are not
available with all models. For more information
about the specifications of a particular model,
see Section 1.3: Specifications.

1.2 Features
1. Fan status monitoring and alarm: To prevent system overheating
and damage, the CPU fan can be monitored for speed and failure.
The fan is set for its normal RPM range and alarm thresholds.
2. Temperature monitoring and alert: To prevent system overheat-
ing and damage, the CPU card supports processor thermal sensing
and auto-protection.
3. Voltage monitoring and alert: System voltage levels are moni-
tored to ensure stable current flows to critical components. Voltage
specifications will become even more critical for processors of the
future. Thus monitoring will become ever more necessary to ensure
proper system configuration and management.
4. ATX soft power switch: Through the BIOS, the power button can
be defined as the "Standby" (aka "Suspend" or "Sleep") button or as
the "Soft-Off" button (see Section 3.7.8 Soft-off by PWR-BTN).
Regardless of the setting, pushing the power button for more than 4
seconds will enter the Soft-Off mode.
5. Power-on by modem (requires modem): This allows a computer
to be turned on remotely through an internal or external modem.
Users can thus access information on their computers from any-
where in the world.
6. Power-on by LAN: This allows you to remotely power up your
system through your network by sending a wake-up frame or sig-
nal. With this feature, you can remotely upload/ download data to/
from systems during off-peak hours.
7. Message LED: Chassis LEDs now act as information providers.
The way a particular LED illuminates indicates the stage the com-
puter is in. A single glimpse provides useful information to the
user.
8. CMOS RAM backup: When BIOS CMOS setup has been com-
pleted, data in the CMOS RAM is automatically backed up to the
Flash ROM. This is particularly useful in industrial environments
which may cause soft errors. Upon such an error occurring, BIOS
will check the data, and automatically restore the original data for
booting.

PCA-6006 User’s Manual 4
9. More:
• Power On by Alarm: Powers up your computer at a certain time.
• Virus warning: During and after system boot-up, any attempt to write to
the boot sector or partition table of the hard disk drive will halt the sys-
tem. In this case, a warning message will be displayed. You can then
run your anti-virus program to locate the problem
