Technical Support
We want you to get the maximum performance from your prod-
ucts. So if you run into technical difficulties, we are here to help.
For 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 can’t 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.

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 service. If an Advantech product ever does prove 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 (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 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 completely filled-out
Repair and Replacement Order Card and a photocopy of 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.

Configuration
This chapter gives background information
on the PCA-6157. It then shows you how to
configure the card to match your applica-
tion and prepare it for installation into your
PC.
Sections include:
• Card specifications
• Safety precautions
• Jumper settings
• Board layout

2PCA-6157 User's Manual
Introduction
The PCA-6157 industrial grade CPU card uses Intel's highly
acclaimedPentiumP54C type 75/90/100/120/133/150/166 MHz CPUs
and 82437FX "Triton" chipset. The card works with standard ISA
and/or ISA/PCI bus passive backplanes.
In addition to the Pentium's 16 KB on-chip cache memory, the card
hasan extra256 KB2nd-level write-backcache. ThePCA-6157 also
supports 8 to 128 MB of on-board DRAM. It has two PCI EIDE
interfaces (for up to four devices), a PCI SCSI-II interface, and an
FDD interface (for up to two devices). Other features include two
RS-232serial ports (16C550UARTswith 16-byte FIFOorcompati-
ble) and one enhanced parallel port (supports EPP/ECP). The card's
high speed PCI EIDE controller supports mode 4 operation, which
provides data transfer rates of over 16 MB/sec. and allows drive
capacities of up to 8.4 GB for connecting tape drives, CD-ROMs,
optical devices, etc.
In addition, the EBM3x-JA has a temperature sensor for the
Pentium CPU. It automatically turns on the CPU cooling fan and
outputs a CPU overheat alarm digital signal when the CPU tempera-
ture exceeds the upper-limit value set by BIOS. This ensures CPU
card reliability and lengthens CPU life.
The PCA-6157's 32-bit passive PCI interface provides burst transfer
speeds of up to 132 MB per second. The interface eliminates data
transfer congestion and improves performance of high bandwidth
applications such as graphics, video and LANs. The card also
provides a standard ISA bus interface for non-PCI adapter cards,
so you can still take advantage of the card's powerful on-board
PCI-EIDE and PCI SCSI-II controller when the card is plugged into
an ISA bus passive backplane. You can also plug the PCA-6157
into a PCI/ISA passive backplane for use with high performance
PCI-bus I/O cards.
The PCA-6157L does not have SCSI chip and temperature sensor.

Chapter 1 Hardware configuration 3
The card has power on self test (POST) LEDs for quick and simple
fault analysis. A backup of CMOS data is stored in the EEPROM,
which protects data even after the battery has failed. The industri-
al-grade construction of this card allows it to withstand continuous
operation in harsh environments at temperatures up to 140°F
(60° C). Also included is a 12-level watchdog timer, which resets the
CPU or generates an interrupt if a program cannot be executed
normally. This enables reliable operation in stand-alone or unat-
tended environments.

Initial inspection
Before you begin installing your card, please make sure that the
following materials have been shipped:
• 1 PCA-6157 CPU card
• 1 Pentium CPU and cooling fan (optional)
• 1 User's manual
• 1 SCSI driver diskette (3½")* and 1 Bus master utility disk
• 1 Parallel port adapter(26-pin)
• 1 6-pin mini-DIN keyboard&PS/2 mouse adapter
• speaker/HDD access/reset harness.
• 1FDD/2 EIDE cableand1 SCSI cable
*Note:PCA-6157 only
If any of these items are missing or damaged, contact your distribu-
tor or sales representative immediately.
We have carefully inspected the PCA-6157 mechanically and
electrically before shipment. It should be free of marks and scratch-
es and in perfect working order upon receipt.
As you unpack the PCA-6157, check it for signs of shipping
damage (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.
Caution! Always ground yourself to remove any static
chargebeforetouchingtheCPU card. Modern
electronic devices are very sensitive to static
electric charges.Try to use a grounding wrist strap
at all times. Place all electronic components in a
static-dissipative surface or static-shielded bag
when they are not in the chassis.

Jumper settings
This section provides instructions on how to configure your card
by setting jumpers. It also includes the card's default settings and
your options for each jumper.
How to set jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To
“close” a jumper you connect the pins with the clip. To “open” a
jumper you remove the clip. Sometimes a jumper consists of a set of
three pins, labeled 1, 2 and 3. In this case you connect either pins 1
and 2, or 2 and 3.
A pair of needle-nose pliers may be useful when setting jumpers.
CPU type and clock speed (JP1, JP16)
The user can choose the CPU frequency by setting the clock
generator jumper (JP1, JP16). If you change processor in the future,
you must make sure that the jumpers are configured for the correct
CPU clock speed. Do this before installing and applying power to
the CPU board.

Watchdog timer – system reset/IRQ11 (JP19)
When CPU processing has come to a halt, the watchdog timer can
either reset the system or generate an interrupt on IRQ11. This can
be set via a two-pin jumper (JP19) as shown below:
