General Information
PCA-6187 User’s Manual 2
Chapter 1 Hardware Configuration
1.1 Introduction
The PCA-6187 Series all-in-one industrial grade single board computer is
a high performance and full-featured computing engine. It follows the
PICMG 1.0 specification and meets most requirements for industrial
applications.
The PCA-6187 uses Intel's 865G chipset to support Intel's Socket 478
Pentium 4 and Celeron processor with 800/533/400 MHz front side bus.
The dual channel DDR 400 SDRAM interface provides bottle neck free
memory bandwidth up to 6.4GB/s. In addition to the two EIDE interfaces
(up to four devices), it features a high performance serial ATA interface
(up to 150MB/s) which eases cabling to hard drives in industrial chassis
with thin and long cables. Other features include chipset built-in high per-
formance VGA interface, dual Giga-bit Ethernet ports, dual channel Ultra
160 SCSI interface, six USB 2.0 ports (up to 480 Mbps), and other stan-
dard PC functions like two RS-232 serial ports, one enhanced parallel
port and floppy disk interface.
The PCA-6187 Series offers several impressive industrial features such
as: CMOS data backup, which is stored in the Flash memory, which pro-
tects data even after battery failure. Also included is a 256-level watch-
dog timer, which resets the CPU if a program cannot be executed
normally. This enables reliable operation in unattended environments.
The remote management interface enables the PCA-6187 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 Table 1.1 : Comparison table and Section
1.3: Specifications.

1.2 Features
1. High performance: The PCA-6187 uses Intel 865G chipset which
offers high-bandwidth interfaces such as dual-channel DDR400
main memory, 800 MHz system bus, integrated graphics controller
with Intel® Extreme Graphics 2 Technology, Intel® Communica-
tion Streaming Architecture featuring a Dedicated Network Bus
(DNB) interface for Gigabit Ethernet (GbE) and Hi-Speed USB 2.0
connectivity to ensure the flexibility and performance you expect.
2. Remote management: System healthy status including CPU fan,
CPU temperature and system voltages levels are monitored to
ensure stable operation. A remote monitoring interface is reserved
for remote management through Ethernet by using Advantech's
SNMP-1000 system management module.
3. BIOS CMOS backup and restore: When BIOS CMOS setup has
been completed, data in the CMOS RAM is automatically backed
up to the Flash ROM. This is particularly useful in harsh environ-
ments which may cause setup data loss such as battery failure.
Upon such an error occurring, BIOS will check the data, and auto-
matically restore the original data for booting.
4. Supports Hyper-Threading : This allows a single HT-enabled
Pentium 4 processor to process two threads simultaneously. By
building two logical processors into a single physical processor, the
performance and utilization of the processor resource will both
increase. Users can obtain a higher CPU performance while Hyper-
Threading is enabled.

1.7 Safety Precautions
Notice: Before install your PCA-6187 into a chassis, make sure that all components
on both sides of the CPU card do not touch any metal parts, especially the chassis
wall and add-on card at the adjacent slot.
Warning! Always completely disconnect the power cord
from your chassis whenever you work with the
hardware. Do not make connections while the
power is on. Sensitive electronic components
can be damaged by sudden power surges. Only
experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any static
charge before touching the single board com-
puter. Modern electronic devices are very sen-
sitive to static electric charges. As a safety
precaution, use a grounding wrist strap at all
times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.
Caution! The computer is provided with a battery-pow-
ered Real-time Clock circuit. There is a danger
of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type rec-
ommended by the manufacturer. Discard used
batteries according to manufacturer's instruc-
tions.
PCA-6187 User’s Manual 12
1.8 Jumper Settings
This section provides instructions on how to configure your single board
computer by setting the jumpers. It also includes the single board com-
puter's default settings and your options for each jumper.
1.8.1 How to set jumpers
You can configure your single board computer to match the needs of your
application by setting the jumpers. A jumper is a metal bridge that closes
an electrical circuit. 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” (or turn ON) a jumper, you connect the pins with the
clip. To “open” (or turn OFF) 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.
1.8.2 CMOS clear (J1)
The PCA-6187 single board computer contains a jumper that can erase
CMOS data and reset the system BIOS information. Normally this
jumper should be set with pins 1-2 open. If you want to reset the CMOS
data, set J1 to 1-2 closed for just a few seconds, and then move the jumper
back to 1-2 open. This procedure will reset the CMOS to its default set-
ting.
1.8.3 Watchdog timer output (J2)
The PCA-6187 contains a watchdog timer that will reset the CPU or send
a signal to IRQ11 in the event the CPU stops processing. This feature
means the PCA-6187 will recover from a software failure or an EMI
problem. The J2 jumper settings control the outcome of what the com-
puter will do in the event the watchdog timer is tripped.

1.9 System Memory
The PCA-6187 has four sockets for 184-pin dual inline memory modules
(DIMMs) in two separated memory channels. It can operate with single
channel or dual channel modules. We recommend to use dual channel
mode to provide optimized performance.
All these sockets use 2.5 V unbuffered double data rate synchronous
DRAMs (DDR SDRAM). They are available in capacities of 128, 256,
512 and 1024 MB. The sockets can be filled in any combination with
DIMMs of any size, giving a total memory size between 128 MB and 4
GB.
Note: System resources such as PCI and AGP require physical
memory address locations that reduce available memory
addresses above 3GB. This may result in less than 4GB of mem-
ory being available to the operating system and applications.

1.9.1 CPU FSB and memory speed
The PCA-6187 can accept DDR SDRAM memory chips without parity.
Also note: The PCA-6187 accepts PC2100 (DDR266), PC2700 (DDR
333) and PC3200 (DDR 400) DDR SDRAM, depending on the CPU
front side bus frequency (FSB). Please refer below table for the relation-
ship between the CPU FSB and memory speed.
The PCA-6187 does not support ECC (error checking and correction).
Memory modules with 9 SDRAM chips/side support ECC; modules with
8 chips/side do not support ECC.
1.9.2 Dual channel configuration
The four DIMM sockets are arranged in two channels: DIMM1 &
DIMM2 in channel A; DIMM3 & DIMM4 in channel B. To enable dual
channel operation, please install a matched pair of DIMMs in DIMM1 &
DIMM3 (green sockets). If additional memory is to be used, another
matched pair of DIMMs have to be installed in DIMM2 & DIMM4 (pur-
ple sockets).
"Matched pair of DIMMs" means: same in speed (DDR266, DDR333,
DDR400), same in size (128MB, 256MB, 512MB or 1GB), same in chip
density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other
memory configuration will result in single channel memory operation.

1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket
are in the "open" position. i.e. The handles lean outward. Slowly slide the
DIMM module along the plastic guides on both ends of the socket. Then
press the DIMM module right down into the socket, until you hear a
click. This is when the two handles have automatically locked the mem-
ory module into the correct position of the DIMM socket. To remove the
memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
1.11 Processor Installation
The CPU on the board must have a fan or heat sink attached, to prevent
overheating.
Warning: Without a fan or heat sink, the CPU will over-heat and cause
damage to both the CPU and the single board computer. To install a CPU,
first turn off your system and remove its cover. Locate the processor
socket 478.
1. Make sure the socket 478 lever is in the upright position. To raise the
lever, pull it out to the side a little and raise it as far as it will go.
2. Place the CPU in the empty socket. Follow the instructions that came
with the CPU. If you have no instructions, complete the following proce-
dure. Carefully align the CPU so it is parallel to the socket and the
notches on the corners of the CPU correspond with the notches on the
inside of the socket. Gently slide the CPU in. It should insert easily. If it
does not insert easily, pull the lever up a little bit more.
3. Press the lever down. The plate will slide forward. You will feel some
resistance as the pressure starts to secure the CPU in the socket. This is
normal and will not damage the CPU. When the CPU is installed, the
lever should snap into place at the side of the socket.
Note : The CPUs made with 0.18 micro-meter process technology
("Willamette") cannot be supported by PCA-6187.

Chapter 2 Connecting Peripherals
2.1 Introduction
You can access most of the connectors from the top of the board while it
is installed in the chassis. If you have a number of cards installed or have
a packed chassis, you may need to partially remove the card to make all
the connections.
2.2 1st & 2nd (CN1, CN2) IDE Connectors
You can attach up to four IDE (Integrated Drive Electronics) drives to the
PCA-6187’s built-in controller. The primary (CN1) and secondary (CN2)
connectors can each accommodate two drives.
Wire number 1 on the cable is red or blue and the other wires are gray.
Connect one end to connector CN1 or CN2 on the single board computer.
Make sure that the red/blue wire corresponds to pin 1 on the connector (in
the upper right hand corner). See Chapter 1 for help finding the connec-
tor.
Unlike floppy drives, IDE hard drives can connect in either position on
the cable. If you install two drives to a single connector, you will need to
set one as the master and the other as the slave. You do this by setting the
jumpers on the drives. If you use just one drive per connector, you should
set each drive as the master. See the documentation that came with your
drive for more information.
Connect the first hard drive to the other end of the cable. Wire 1 on the
cable should also connect to pin 1 on the hard drive connector, which is
labeled on the drive circuit board. Check the documentation that came
with the drive for more information.
Connect the second hard drive to the remaining connector (CN2 or CN1),
in the same way as described above.

2.3 Floppy Drive Connector (CN3)
You can attach up to two floppy disk drives to the PCA-6187's on board
controller. You can use 3.5" (720 KB, 1.44 MB) drives.
The single board computer comes with a 34-pin daisy-chain drive con-
nector cable. On one end of the cable is a 34-pin flat-cable connector. On
the other end are two sets of 34-pin flat-cable connector (usually used for
3.5" drives). The set on the end (after the twist in the cable) connects to
the A: floppy drive. The set in the middle connects to the B: floppy drive.
2.4 Parallel Port (CN4)
The parallel port is normally used to connect the single board computer to
a printer. The PCA-6187 includes an onboard parallel port, accessed
through a 26-pin flat-cable connector, CN4. The card comes with an
adapter cable which lets you use a traditional DB-25 connector. The cable
has a 26-pin connector on one end and a DB-25 connector on the other,
mounted on a retaining bracket. The bracket installs at the end of an
empty slot in your chassis, giving you access to the connector.
The parallel port is designated as LPT1, and can be disabled or changed
to LPT2 or LPT3 in the system BIOS setup.
To install the bracket, find an empty slot in your chassis. Unscrew the
plate that covers the end of the slot. Screw in the bracket in place of the
plate. Next, attach the flat-cable connector to CN4 on the CPU card. Wire

10/100Mbps CSMA/CD and IEEE 802.3ab 1000Base-T standards. It is
supported by all major network operating systems and is 100% Novell
NE-2000 compatible. An onboard RJ-45 jack provides convenient 10/
100Base-T or 10/100/1000Base-T RJ-45 operation.
2.8 Serial Ports (COM1 : CN9; COM2 : CN10 )
The PCA-6187 offers two serial ports, CN9 as COM1 and CN10 as
COM2. These ports can connect to serial devices, such as a mouse or a
printer, or to a communications network.
The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do this
in the system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.

Chapter 3 Award BIOS Setup
3.1 Introduction
Award’s BIOS ROM has a built-in setup program that allows users to
modify the basic system configuration. This type of information is stored
in battery-backed memory (CMOS RAM) so that it retains the setup
information when the power is turned off.
3.1.1 CMOS RAM Auto-backup and Restore
The CMOS RAM is powered by an onboard button cell battery. When
you finish BIOS setup, the data in CMOS RAM will be automatically
backed up to Flash ROM. If operation in harsh industrial environment
cause a soft error, BIOS will recheck the data in CMOS RAM and auto-
matically restore the original data in Flash ROM to CMOS RAM for
booting.
Note: If you intend to change the CMOS setting with-
out restoring the previous backup, you have to
click on "DEL" within two seconds of the
"CMOS checksum error..." display screen mes-
sage appearing. Then enter the "Setup" screen
to modify the data. If the "CMOS checksum
error..."message appears again and again,

5.1 Introduction
The PCA-6187 has VGA onboard, you need to install the VGA driver to
enable the function.
The Intel® 865G Graphics Memory Controller Hub (the 865G GMCH)
provides an integrated graphics accelerator delivering cost competitive
3D, 2D, and video capabilities. The GMCH contains an extensive set of
instructions for 3D operations, BLT and Stretch BLT operations, motion
compensation, overlay, and display control. The 865G GMCH’s video
engines support video conferencing and other video applications. The
GMCH does not support a dedicated local graphics memory interface; it
may only be used in a UMA configuration. The features include:
• Built-in 2D/3D VGA controller.
• Use Intel® Extreme Graphics Architecture
• Integrated 350MHz RAMDAC that can directly drive a progressive
scan analog monitor up to a resolution of 2048x1536 at 75Hz
• Maximum 3D resolution supported : 1600 x 1200 x 32 @ 85Hz.
• H/W motion compensation assistance for s/w MPEG 2 decoding.
• Software DVD at 30 fps Full Screen.
5.2 Dynamic Video Memory Technology
The following is quoted from "Intel® 865G Chipset Dynamic Video
Memory Technology", document number : 253144-001 :
The method of memory allocation where the Operating System, Applica-
tion and Graphics Memory come from a unified System Memory pool
known as Unified Memory Architecture (UMA).
Dynamic Video Memory Technology (DVMT) is an enhancement of the
UMA concept, wherein the optimum amount of memory is allocated for
balanced graphics and system performance, through Direct AGP (known
as Non-Local Video Memory, or NLVM), and a highly efficient memory
utilization scheme. DVMT ensures the most efficient use of available
memory – regardless of frame buffer or main memory sizing – for maxi-
mum 2D/3D graphics performance.
53 Chapter 5
DVMT dynamically responds to system requirements, and application
demands, by allocating the proper amount of display, texturing and buffer
memory after the operating system has booted. For example, a 3D appli-
cation when launched may require more vertex buffer memory to
enhance the complexity of objects, or more texture memory to enhance
the richness of the 3D environment. The operating system views the inte-
grated graphics driver as an application, which uses Direct AGP to
request allocation of additional memory for 3D applications, and returns
the memory to the operating system (OS) when no longer required.
The Intel Extreme Graphics Driver determines the size of the pre-allo-
cated memory needed and will make additional Non-Local Video Mem-
ory requests to achieve the amount needed for the display and application
requirement. The video memory size in the Intel® 865G chipset varies
and is determined using several factors. The key factors are system
resources and system activity. The maximum video memory is up to
64MB SDRAM

PCA-6187 User’s Manual 64
Chapter 7 SCSI Setup & Configuration
7.1 Introduction
The PCA-6187 is equipped with an Adaptec AIC-7899 single-chip PCI-
to-SCSI host adapter which provides a dual channel Ultra 160 multi-
tasking interface between your computer.s PCI bus and SCSI devices
(disk drives, CD-ROM drives, scanners, tape backups, removable media
drives, etc.). Ultra 160 is a new generation of SCSI technology that
expands SCSI performance from 80 MBytes/sec to 160 MBytes/ sec. Up
to a total of 15 SCSI devices can be connected to each of the SCSI con-
nectors.
The AIC-7899 combines this Ultra 160 SCSI technology with Adaptec.s
SpeedFlex. technology. SpeedFlex allows the Adaptec SCSI card to be
backwards compatible with previous generations of SCSI products, while
allowing newer Ultra 160 SCSI devices to operate at the higher 160
MBytes/sec rate.
There are 3 SCSI connectors on the CPU card: CN50 and CN51 for Ultra
160 devices, and CN52 for 50-pin SCSI devices. You can use Ultra 160
and Ultra wide devices simultaneously without compromising the perfor-
mance.
If you need to configure the SCSI, the onboard SCSI Select configuration
utility allows you to change host adapter settings without opening the
computer or handling the board. The SCSI Select utility also contains a
utility to low-level format and verifies the disk media on your hard disk
drives.
Note: If any peripheral is running at SE mode, the
Ultra 160 SCSI segment will run at speeds up to
40 MBytes/sec only instead of 160 MBytes/sec.

SCSI (pronounced .scuzzy.) stands for Small Computer Systems Inter-
face. SCSI is an industry standard computer interface for connecting
SCSI devices to a common SCSI bus.
A SCSI bus is an electrical pathway that consists of a SCSI interface
installed in a computer and one or more SCSI devices. SCSI cables are
used to connect the devices to the SCSI interface. For the SCSI bus to
function properly, a unique SCSI ID must be assigned to the SCSI inter-
face and each SCSI device connected to it, and the SCSI bus must be
properly terminated.
7.3 SCSI IDs
Each device attached to the SCSI bus, as well as the SCSI controller
itself, must be assigned a unique SCSI ID number from 0 to 15. A SCSI
ID uniquely identifies each SCSI device on the SCSI bus and determines
priority when two or more devices are trying to use the SCSI bus at the
same time.
Refer o the device.s documentation to set the SCSI ID. Here are some
general guidelines for SCSI IDs:
• For internal SCSI devices, the SCSI ID usually is set by configuring a
jumper on the device.
• For external SCSI devices, the SCSI ID usually is set with a switch on
the back of the device.
• SCSI ID numbers don.t have to sequential, as long as the SCSI control-
ler and each device has a different number.
• For example, you can have an internal SCSI device with ID 0, and an
external SCSI device with ID 6.
• SCSI ID 7 has the highest priority on the SCSI bus. The priority of the
remaining IDs, in descending order, is 6 to 0, then 15 to 8.
• The on-boards SCSI interface is preset to SCSI ID 7 and should not be
changed. This gives it the highest priority on the SCSI bus.
• Most internal SCSI hard disk drives come from the factory pre-set to
SCSI ID 0.
• If you have 8-bit (or Narrow) SCSI devices, they must use SCSI IDs 0,
1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first SCSI hard
disk drive.
PCA-6187 User’s Manual 66
• If you are booting your computer from a SCSI hard disk drive con-
nected to the SCSI bus, the Boot SCSI ID setting in the SCSISelect
utility must correspond to the SCSI ID of the device from which you
are booting. By default, the Boot SCSI ID is set to 0. We recommend
that you do not change this setting.
• In Windows 95/98, you can use the Device Manager to determine
which SCSI ID is assigned to each installed SCSI device.
7.4 Terminating the SCSI Bus
To ensure reliable communication on the SCSI bus, the ends of the SCSI
bus must be properly terminated. This is accomplished when the device at
the end of the each cable, or the end of the cable itself, has a terminator
installed (or enabled). Terminators must be removed, or termination must
be disabled, on devices between the ends of each cable.
Since the method for terminating a SCSI device can vary widely, refer to
the device.s documentation for instructions on how to enable or disable
termination. Here are some general guidelines for termination:
• Internal Ultra 160 and Ultra 2 SCSI devices come from the factory with
termination disabled and cannot be changed. Proper termination for
internal Ultra 160 and Ultra2 SCSI devices is provided by a 68-pin
Internal LVD (low voltage differential) SCSI cable, which has a built-
in terminator at its end.
• Termination on non-Ultra 160 and Ultra2 internal SCSI devices usually
is controlled by manually setting a jumper or a switch on the device, or
by physically removing or installing one or more resistor modules on
the device.
• Termination on most external SCSI devices is controlled by installing
or removing a SCSI terminator. However, termination on some exter-
nal SCSI devices is enable or disabled by setting a switched on the
back of the SCSI device.
The last external Ultra160 or Ultra2 SCSI device must be terminated with
an LVD/SE (low voltage differential/single ended) terminator plug to
ensure that the device will operate at its maximum speed. If you use a dif-
ferent kind of terminator plug, the data I/O rate will decrease.
By default, termination on the SCSI controller itself is set to Automatic
(the preferred method). We recommend that you do not change this
default setting.

7.5 Configuring the SCSI interface with SCSISelect
SCSISelect, included with the CPU card, enables you to change SCSI set-
tings without opening the computer. SCSISelect also enables you to low-
level format or verify the disk media of your SCSI hard disk drives. The
following table lists the available and default settings for each SCSISelect
option.
Note: The default settings are appropriate for most
systems. Run SCSISelect if you need to
change or view current settings, or if you would

Appendix A Programming the watchdog
A.1 Programming the Watchdog Timer
The PCA-6187's watchdog timer can be used to monitor system software
operation and take corrective action if the software fails to function after
the programmed period. This section describes the operation of the
watchdog timer and how to program it.
A.1.1 Watchdog timer overview
The watchdog timer is built-in the super I/O controller W83627HF. It
provides the following functions for user programming:
• Can be enabled and disabled by user's program.
• Timer can be set from 1 to 255 seconds or 1 to 255 minutes.
• Generates an interrupt or resets signal if the software fails to reset the
timer after time-out.
A.1.2 Reset/ Interrupt selection
The J2 jumper is used to select reset or interrupt (IRQ 11) in the event the
watchdog timer is tripped. See Chapter 1 for detailed jumper settings.
A.1.3 Programming the Watchdog Timer
The I/O port address of the watchdog timer is 2E(hex) and 2F(hex).
2E (hex) is the address port. 2F(hex) is the data port.
You must first assign the address of register by writing address value
into address port 2E(hex), then write/read data to/from the assigned
register through data port 2F (hex).
Note: The interrupt output of the watchdog timer is a low
level signal. It will be held low until the watchdog timer
is reset.
