Product warranty
Advantech warrants to you, the original purchaser, that each of its
products will be free from defects in materials and workmanship for
one year 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.
Because of Advantech’s high quality-control standards and rigorous
testing, most of our customers never need to use our repair service. 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.

If any of these items are missing or damaged, contact your
distributor or sales representative immediately.
We have carefully inspected the PCA-6176 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-6176, 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

2 PCA-6176 User's Manual
1.1 Introduction
The PCA-6176 series all-in-one industrial grade CPU card uses
Intel's highly acclaimed Pentium®II/III processor, together with the
Intel 440BX PCI chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 512 KB on-chip L2 cache, eliminating the need
for external SRAM chips. It has two PCI EIDE interfaces (for up to
four devices), and an FDD 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 support for two USB (Universal Serial Bus) ports.
The PCI Bus Master IDE controller supports Ultra DMA/33
operation. This provides data transfer rates of over 33 MB/sec.
System BIOS supports boot-up from an IDE CD-ROM, SCSI
CD-ROM, ZIP and LS-120.
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 opera-
tion in unattended environments.
The PCA-6176 series offers several impressive industrial features
such as a VGA (AGP) controller, a PCI Ultra2 SCSI controller, a
10/100Base-T networking controller, and an ISA High Drive. All
these make it an ideal choice for applications that require both high
performance and full functionality.

1.5 Jumpers and Connectors
Connectors on the PCA-6176 board link it to external devices such as
hard disk drives and a keyboard. In addition, the board has a number
of jumpers used to configure your system for your application.
The tables below list the function of each of the board jumpers and
connectors. Later sections in this chapter give instructions on setting
jumpers. Chapter 2 gives instructions for connecting external devices
to your card.
