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 other than repair personnel authorized by
Advantech, or which have been subject to misuse, abuse, accident
or improper installation. Advantech assumes no liability as a
consequence of such events under the terms of this Warranty.
Because of Advantech’s high quality-control standards and
rigorous testing, most of our customers never need to use our
repair and replacement service. If an Advantech product ever does
prove defective, it will be repaired at no charge during the warran-
ty 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 (e.g.
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 other 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 completely filled-out
Repair and Replacement Order Card and a photocopy of a
dated proof of purchase (such as your sales receipt) in a
shippable container. A product returned without dated proof of
purchase 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.

Introduction
The PCA-6155 packs all the functions of an industrial computer,
including IDE, FDD controller, RS-232 ports and a parallel port onto a
half-size card. This PICMG-compliant, all-in-one board supports Intel
Pentium and Cyrix 6x86 processors and can be used with PCIMG-
compliant PCI/ISA passive backplanes.
The PCA-6155's two PCI-bus enhanced IDE ports support PIO mode
4 and DMA bus master IDE transfer, enabling data transfer rates in
excess of 16 MB/second. Up to four IDE devices can be connected,
including large hard disks (up to 8 GB), CD-ROM drives, tape backup
drives, or other enhanced IDE devices.
On-board features also include two RS-232 ports with 16C550 UARTs
(one of which can also function as an infrared port) and one bidirec-
tional SPP/EPP/ECP parallel port. It provides COAST (Cache On A
STick) pipeline burst synchronous cache RAM. The PCA-6155 can
pack up to 128 MB of memory, using normal DRAM or EDO RAM.
If program execution is halted by a program bug or EMI, the board's
63-level watchdog timer can automatically reset the CPU or generate
an interrupt. This ensures reliability in unmanned or standalone
systems. The watchdog timer interval is set by software and can be
changed during runtime, eliminating jumper switch setting.
