Product warranty
Advantech warrants to you, the original purchaser, that each of its prod-
ucts will be free from defects in materials and workmanship for two years
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 instal-
lation. 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 man-
ual, 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 war-
ranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

PCA-6185 User’s Manual 2
Chapter 1 Hardware Configuration
1.1 Introduction
The PCA-6185 Series all-in-one industrial grade single CPU card uses
Intel's high performance Pentium® 4 processor, together with the Server-
Works' GC-SL chipset. The card features two separate 64-bit PCI-X bus,
one for internal deviced and one for external add-on cards. The dual PCI-
X bus ensures the operation of internal devices not to be influenced by
external add-on cards.
The PCA-6185 supports Pentium 4 or Celeron CPU with 533 and 400
MHz front side bus. Based on the NetBurst™ microarchitecture, the
CPU is equipped with 512, 256 or 128 KB on-CPU full-speed cache
memory, providing higher performance than ever before. The 3 DIMM
memory sockets support up to 4 GB PC-200/266 DDR SDRAM, fullfil-
ing the demand on computing performance of of most applications. The
PCA-6185 Series features powerful on-board I/O functions such as single
or dual gigabit Ethernet ports and dual channel Ultra 320 SCSI interface.
This makes it an ideal choice for applications that require both high per-
formance and full functionality.
It has two 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 four USB (Universal
Serial Bus) ports. The PCI enhanced IDE controller supports ATA 33/66/
100 and PIO Mode 4 operation. This provides data transfer rates of up to
100 MB/sec. System BIOS supports boot-up from an IDE CD-ROM,
SCSI CD-ROM, LS-120, IDE HDD, SCSI HDD, ZIP-100, LAN, and
FDD.
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 envi-
ronments.
The remote management interface enables the PCA-6185 to be managed
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/
SNMP System Manager.
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 Specifications.

3 Chapter1
1.2 Features
1. High performance PCI bus: The PCA-6185 provides three inde-
pendent PCI buses: one 32-bit, 33 MHz PCI bus and two 64-bit
PCI-X buses. The 32-bit bus is used for on-board VGA controller.
One of the two high performance PCI-X bus is used for onboard
Gigabit Ethernet and SCSI controllers. The other PCI-X bus is
available for user's add-on cards through the edge connector. This
PCI-X bus is compatible with PCI bus and capable to operate at dif-
ferent speed: 32-bit/33 MHz, 32-bit/66MHz, 64-bit/33 MHz or 64-
bit/66 MHz.
2. Fan status monitoring and alarm: To prevent system overheating
and damage, the CPU fan can be monitored for speed and failure.
The fan is set for its normal RPM range and alarm thresholds.
3. Temperature monitoring and alarm: To prevent system over-
heating and damage, the CPU card supports processor thermal
sensing and auto-protection.
4. Voltage monitoring and alarm: System voltage levels are moni-
tored to ensure stable current flows to critical components. Voltage
specifications will become even more critical for processors of the
future. Thus monitoring will become ever more necessary to ensure
proper system configuration and management.
5. ATX soft power switch: Through the BIOS, the power button can
be defined as the "Standby" (aka "Suspend" or "Sleep") button or as
the "Soft-Off" button (see Soft-off by PWR-BTN, Setion 3.7.8)
Regardless of the setting, pushing the power button for more than 4
seconds will enter the Soft-Off mode.
6. Power-on by modem (requires modem): This allows a computer
to be turned on remotely through an internal or external modem.
Users can thus access information on their computers from any-
where in the world.
7. Message LED: Chassis LEDs now act as information providers.
The way a particular LED illuminates indicates the stage the com-
puter is in. A single glimpse provides useful information to the
user.
8. CMOS RAM backup: When BIOS CMOS setup has been com-
pleted, data in the CMOS RAM is automatically backed up to the
Flash ROM. This is particularly useful in industrial environments

PCA-6185 User’s Manual 4
which may cause soft errors. Upon such an error occurring, BIOS
will check the data, and automatically restore the original data for
booting.

PCA-6185 User’s Manual 10
Notes: Note1: Shall any incompatibility occur when
using addon cards running at 66MHz PCI or 66
MHz PCI-X, please lower down the PCI bus
frequency to 33MHz by setting jumpers on the
backplane. You can find how to set the jumpers
on the User's Note of the backplane.
Note 2: Due to the limitation of the GC-SL
chipset, the PCI slot with ID select=AD31 on
backplanes will not work.
Note 3: The PCA-6185 does not support
"Wake-on-LAN" feature.
Note 4: The PCA-6185 supports 66MHz PCI-X
operation when it is used with PCI-X compati-
ble add-on cards and backplanes. The PCA-
6106P3VX-A1 and PCA-6103P2VX-A1 sup-
port PCI-X operation.
