Your satisfaction is our primary concern. Here is a guide to
Advantech’s customer services. To ensure you get the full benefit of
our services, please follow the instructions below carefully.
Technical Support
We want you to get the maximum performance from your products.
So if you run into technical difficulties, we are here to help. For the
most frequently asked questions, you can easily find answers in your
product documentation. These answers are normally a lot more
detailed than the ones we can give over the phone.
So please consult this manual first. If you still cannot find the answer,
gather all the information or questions that apply to your problem, and
with the product close at hand, call your dealer. Our dealers are well
trained and ready to give you the support you need to get the most
from your Advantech products. In fact, most problems reported are
minor and are able to be easily solved over the phone.
In addition, free technical support is available from Advantech
engineers every business day. We are always ready to give advice on
application requirements or specific information on the
installation and operation of any of our products.

iv
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.

v

2 PCA-6175 User's Manual
1.1 Introduction
The PCA-6175 industrial grade CPU card uses Intel's highly
acclaimed Pentium®II processor and Intel 440LX 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, and
allows drive capacities up to 8.4 GB. System BIOS supports boot-up
from an IDE CD-ROM.
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.
