Product warranty
Advantech warrants to you, the original purchaser, that each of its
products 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 installation. 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
manual, 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 warranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

Initial Inspection

1700060202
• 1 SCSI cable (optional), P/N 1701060000
• 1 USB cable (optional), P/N 1700100170
If any of these items are missing or damaged, contact your distributor
or sales representative immediately.
We have carefully inspected the PCA-6277 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-6277, 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.

CHAPTER

2PCA-6277 User's Manual
1.1 Introduction
The PCA-6277 Series all-in-one industrial grade dual CPU card uses
Intel's highly acclaimed Pentium® III processor, together with the VIA
Apollo Pro133A chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 256 KB on-CPU L2 cache, eliminating the need
for external SRAM chips. It has two PCI EIDE interfaces (for up to
four devices) and a floppy disk drive interface (for up to two devices).
Other features include two RS-232 serial ports (16C550 UARTs with
16-byte FIFO or compatible), one enhanced parallel port (supports
EPP/ECP) and four USB (Universal Serial Bus) ports. The PCI en-
hanced IDE controller supports Ultra DMA 33/66/100 and PIO Mode 4
operation. This provides data transfer rates of up to 33/66/100 MB/sec.
System BIOS supports boot-up from an IDE CD-ROM, SCSI CD-ROM,
LS-120, IDE HDD, SCSI HDD, ZIP-100, LAN, and FDD.
A backup of CMOS data is stored in the Flash memory, which protects
data even after a battery failure. Also included is a 63-level watchdog
timer, which resets the CPU or generates an interrupt if a program
cannot be executed normally. This enables reliable operation in
unattended environments.
The PCA-6277 Series offers several impressive industrial features such
as a VGA (AGP) controller, an ultra 160 SCSI controller, dual 10/100
Base-T networking controller, four DIMM slots for a total of 2 GB
RAM memory, and an ISA High Drive. All these make it an ideal
choice for applications that require both high performance and full
functionality.
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.

Chapter 1 Hardware Configuration 3
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 alarm: To prevent system overheat-
ing and damage, the CPU card supports processor thermal sensing
and auto-protection.
3. Voltage monitoring and alarm: 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 3.6.6 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
anywhere 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
signal. 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
computer is in. A single glimpse provides useful information to the
user.

4PCA-6277 User's Manual
8. Jumper free mode: When enabled, this allows processor settings
and easy overclocking of frequency and Vcore voltages all through
the BIOS setup. Easy-to-use DIP switches instead of jumpers are
included in case you want to manually adjust the processor's
external frequency.
9. CMOS RAM backup: When BIOS CMOS setup has been complet-
ed, 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.
10. 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 system. In this case, a warning message will
