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.
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.

CHAPTER

2 PCA-6276 User's Manual
1.1 Introduction
The PCA-6276 all-in-one industrial grade CPU card uses two of
Intel's highly acclaimed Celeron™processors, together with the Intel®
440BX PCI chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 128 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
SPP/EPP/ECP) and one USB (Universal Serial Bus) port. The PCI
enhanced IDE controller supports Ultra DMA/33 and PIO Mode 4
operation. This provides data transfer rates of over 33 MB/sec.
System BIOS supports boot-up from an IDE CD-ROM, SCSI
CD-ROM 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 operation
in unattended environments.
The PCA-6276 offers several impressive industrial features such as a
VGA (AGP) controller, a 10/100Base-T networking controller, four
DIMM slots for a total of 1 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 in this chapter.
