This chapter gives background information on the PCA-6181. It then shows you
how to configure the card to match your
application and prepare it for installation
into your PC.
Sections include:
• Introduction
• Features
• Specifications
• Board Layout
• Jumpers and Connectors
• Safety Precautions
• Jumper Settings

• Memory Installation Procedures
• Cache Memory
• CPU Installation
1.1 Introduction
The PCA-6181 Series all-in-one industrial grade single board computer
is a high performance and full-featured computing engine. It meet
most of the requirements of industrial applications.
The PCA-6181 supports Intel's Pentium III and Celeron processor. The
CPU provides 128/256/512 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
EPP/ECP) and two USB (Universal Serial Bus) ports. The PCI enhanced IDE controller supports Ultra DMA/33/66/100 and PIO Mode 4
operation. This provides data transfer rates of 33/66/100 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 environments.
The PCA-6181 Series offers several impressive industrial features such
as chipset built-in VGA (AGP) interface, dual 10/100Base-T networking
controller, two DIMM slots for a total of 1.5 GB RAM memory, and a
high driving ISA bus.
The remote management interface enables the PCA-6181 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.

PCA-6181 User's Manual
1.2 Features
1. On-board hardware monitoring: System healthy status including
CPU fan, CPU temperature and system voltages levels are monitored to ensure stable operation. proper system configuration and
management. A remote monitoring interface is reserved for remote
management through Ethernet by using Advantech's SNMP-1000
system management module.
2. 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. Regardless of the setting, pushing the
power button for more than 4 seconds will enter the Soft-Off mode.
3. 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 anywhere in
the world.
4. Power-on by LAN: This allows you to remotely power up your
system through your network by sending a wake-up frame or
signal. With this feature, you can remotely upload/ download data
to/from systems during off-peak hours.
5. Message LED: Chassis LEDs now act as information providers.
The way a particular LED illuminates indicates the stage the
computer is in. A single glimpse provides useful information to the
user.
6. More:
• Additional metal bracket for board stabilization
• Power On by Alarm: Powers up your computer at a certain
time
• Virus warning: During and after system boot-up, any attempt
to write to the boot sector or partition table of the hard disk
drive will halt the system. In this case, a warning message will
be displayed. You can then run your anti-virus program to
locate the problem

1.6 Safety Precautions
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 CPU card. Modern electronic
devices are very sensitive to static electric charges.
As a safety precaution, 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.
1.7 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.
1.7.1 How to set jumpers
You configure your card to match the needs of your application by
setting 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.

PCA-6181 User's Manual
1.7.2 CMOS clear (J1)
The PCA-6181 CPU card contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be
set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to
2-3 closed for just a few seconds, and then move the jumper back to 12 closed. This procedure will reset the CMOS to its default setting.

1.7.3 Watchdog timer output (J2)
The PCA-6181 contains a watchdog timer that will reset the CPU or
send a signal to IRQ11 in the event the software fails to reset the
watchdog timer. The J2 jumper settings control the outcome of what
the computer will do in the event the watchdog timer is tripped.

Chapter 1 Hardware Configuration 11
1.8 System Memory
The PCA-6181 has three sockets for 168-pin dual inline memory
modules (DIMMs). All these sockets use 3.3 V unbuffered synchronous DRAMs (SDRAM). DIMMs are available in capacities of 16, 32,
64, 128, 256 or 512 MB. The sockets can be filled in any combination
with DIMMs of any size, giving a total memory size between 16 MB
and 1.5 GB. Use the following table to calculate the total DRAM
memory within your computer:
Table 1-6: DIMM module allocation table
Socket number 168-pin DIMM memory
1 (16, 32, 64, 128, 256 or 512 MB) x 1
2 (16, 32, 64, 128, 256 or 512 MB) x 1
3 (16, 32, 64, 128, 256 or 512 MB) X 1
1.8.1 Supplementary information about DIMMs
Your PCA-6181 can accept SDRAM memory chips with or without
parity. Also note:
• If the PCA-6181 operates at 133/100 MHz, only use PC-133/ PC-100
compliant DIMMs. Most systems will not even boot if non-compliant modules are used. This is due to strict timing issues involved at
this speed.
• SDRAM chips are usually thinner and have higher pin density than
EDO chips.
• Chips with 9 chips/side support ECC; chips with 8 chips/side do not
support ECC.
12
PCA-6181 User's Manual
1.9 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 memory module into the correct position of
the DIMM socket. To remove the memory module, just push both
handles outward, and the memory module will be ejected by the
mechanism in the socket.
1.10 Cache Memory
Since the second level (L2) cache has been embedded into the Intel
Pentium III/Celeron processor, you do not have to take care of either
SRAM chips or SRAM modules. The built-in second level cache in the
Pentium III/Celeron processor yields much higher performance than
the external cache memories. The cache size in the Intel® Pentium III
processor is 256 KB or 512 KB, for Celeron processor is 128 or 256 KB.

Chapter 1 Hardware Configuration 13
1.11 CPU 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 overheat and
cause damage to both the CPU and the motherboard.
To install a CPU, first turn off your system and remove its cover.
Locate the processor socket 370.
1. Make sure the socket 370 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 procedure. 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: To remove a CPU, pull the lever out to the side a
little and raise it as far as it will go. Lift out the CPU.

Connecting Peripherals
This chapter tells how to connect peripherals, switches and indicators to the
PCA-6181 board. 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 your
chassis is very tight, you may need to
partially remove the card to make all the
connections.
2.1 Primary (CN1) and Secondary (CN2) IDE
Connectors
CN1
CN2
You can attach up to four IDE (Integrated Device Electronics) drives to
the IDE connectors. 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 CPU card. 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
connector.
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 one 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.

SCSI Setup and
Configurations
The PCA-6181 features an onboard SCSI
interface. This chapter provides basic
SCSI concepts and instructions for
installing the software drivers with the
SCSI driver disks/CD included in your
package.
6.1 Introduction
The PCA-6181 is equipped with an Adaptec AIC-7899 single-chip PCIto-SCSI host adapter which provides a dual channel Ultra 160 multitasking 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 connectors.
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 performance.
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.
6.2 Understanding SCSI
SCSI (pronounced “scuzzy”) stands for Small Computer Systems
Interface. 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
76
PCA-6181 User’s Manual
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
interface and each SCSI device connected to it, and the SCSI bus must
be properly terminated.
6.3 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 swetch
on the back of the device.
• SCSI ID numbers don’t have to sequential, as long as the SCSI
controller 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 remianing 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 deveices, 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.
Chapter 6 SCSI Setup and Configurations
77
• If you are booting your computer from a SCSI hards disk drive
connected to the SCSI bus, the Boot SCSI ID setting in the
SCSISelect utility must correspond to the SCSI ID of the deveice
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
which SCSI ID is assigned to each installed SCSI device.
©
95/98, you can use the Device Manager to determine
6.4 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 builtin 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
external SCSI devices is enable or disabled by setting a swetich 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
78
PCA-6181 User’s Manual
plug to ensure that the device will operate at its maximum speed. If
you use a different 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.
6.5 Configuring the SCSI interface with
SCSISelect
SCSISelect, included with the CPU card, enables you to change SCSI
settings 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 like to run the SCSI disk
utilities. See the descriptions of each option starting on
next page.

SCSI Bus Interface Definitions
• Host Adapter SCSI ID-(Default: 7) Sets the SCSI ID for
the SCSI controller. The Adaptec SCSI controller AIC-7899 is set
at 7, which gives t the highest priority on the SCSI bus. We
recommend that you do not change this setting.
• SCSI Parity Checking-(Default: Enabled) When set to Enabled,
verifies the accuracy of data transfer on the SCSI bus. Leave this
setting enabled unless any SCSI device does not support SCSI
parity.
• Host Adapter SCSI Termination-(Default: Automatic) Determines
the termination setting for the SCSI card. The default setting for
both the LVD/SE (low voltage differential/single ended) connec
tors and SE connectors is Automatic, which allows the SCSI card
to adjust the termination as needed depending on the finfiguration
of the connected SCSI devices. We recommend that you do not
change these settings.
Boot Device Options
• Boot SCSI ID-(Default: 0) Specifies the SCSI ID of your boot
device. We recommend that you dono t change the default
setting.
• Boot LUN Number-(Default: 0) Specifies which LUN (Logical Unit
Number) to boot from on your boot device. This setting is not
valid unless Multiple LUN Support is Enabled

SCSI Device Configuration
SCSI Device Configuration options can be set individually for each
connected SCSI device.
Note: To configure settings for a SCSI device, you must
know it’s SCSI ID (see Using Disk Utilities on page
23.)
• Sync Transfer Rate-(Default: 160) Determines the maximum
synchronous data transfer rate that the SCSI card supports. Use
the mazimum value of 160 MBytes/sec.
• Initiate Wide Negotiation-(Default: Ye s) When set to Ye s, the
SCSI card attempts 16-bit data transfer (wide negotiation.) When
set to No, the SCSI card uses 8-bit data transfer unless the SCSI
device requests wide negotiation.
Note: Set Initiate Wide Negotiation to NO if you are using an
8-bit SCSI device that hangs or exhibits other perfor
mance problems with 16-bit data transfer rate enabled.
• Enable Disconnection-(Default: Yes) When set to Yes , allows the
SCSI device to disconnect from the SCSI bus. Leave the setting at
Yes if two or more SCSI device is connected, changing the setting
to No results in slightly better performance.
• Send Start Unit Command-(Default: Yes ) When set to Ye s, the
Start Unit Command is sent to the SCSI device at bootup.
The following three options have no effect if the SCSI Card BIOS is
disabled. (The SCSI Cards BIOS is normally enabled by default.)
• Enable Write Back Cache-(Default: N/C) Can be used to enable
or disable the write-back cache on SCSI disk drives connected to
the host adapter. Leave this option at its default setting of N/C
(no change), which usually allow for optimum drive performance.
• BIOS Multiple LUN Support-(Default: No) Leave this setting at
No if the device does not have multiple Logical Unit Numbers
(LUNs.) When set to Ye s , the SCSI card BIOS provides boot
support for a SCSI device with multiple LUNs (for example, a CD
Chapter 6 SCSI Setup and Configurations
83
“juke box” device in which mulitple CDs can be accessed
simultaneously.)
• Include in BIOS Scan-(Default: Yes) When set to Ye s, the SCSI
card BIOS includes the device as part of its BIOS scan at bootup.
Advanced Configuration Options
Note: Do not change the Advanced Configuration Options
unless absolutely necessary.
• Reset SCSI Bus at IC Initialization-(Default: Enabled) When set
to Enabled, the SCSI card generates a SCSI bus reset during its
power-on initialization and after a hard reset.
• Display <Ctrl> <A> Messages during BIOS Initialization (Default: Enabled) When set to Enabled, the SCSI card BIOS
displays the Press <Ctrl> <A> for SCSISelect (TM) Utility!
message on your screen during system bootup. If this setting
disabled, you can still invoke the SCSISelect Utility by pressing
<Ctrl> <A> after the SCSI card BIOS banner appears.
• Extended BIOS Translation for DOS Drives > 1 GByte-(Default:
Enabled) When set to Enabled, provides an extended translation
scheme for SCSI hard disks with capacities greater than 1 GByte.
This setting is necessary only for MS-DOS 5.0 or above; it is not
required for other operating systems, such as NetWare of UNIX.
Caution: Changing the translation scheme destroys all data
Use the MS-DOS Fdisk command to partition a disk laster than
1GByte controlled by the SCSI card BIOS, when using DOS, Win
dows 3.1.x, ro Windows 95/98.
• Verbose/Silent Mode-(Default: Verbose) When set to Verbose,
the SCSI card BIOS displays the host adapter model on the screen
during sustem buildup. When set to Silent, the message is not
displayed during bootup.

PCA-6181 User’s Manual
on the drive. Bue sure to back your disk drives
before changing the translation scheme.
• Host Adapter BIOS (Configuration Utility Reserves BIOS
Space)-(Default: Enabled) Enables or disables the SCSI card
BIOS.
• Leave at Enabled to allow the SCSI card BIOS to scan and
initialize all SCSI devices.
• Set to Disabled: Not scan if the devices on the SCSI bus
(for example, CD-ROM drives) are controlled by software
drivers and do not need the BIOS, and you do not want
the BIOS to scan the SCSI bus.
• Set to Disabled: Scan Bus if you do not need the BIOS,
but you want it to scan the SCSI devices on the bus and
you need to spin up the devices.
The following four options have no effect when the SCSI Card
BIOS is disabled. (The SCSI Card BIOS is normally enabled by
default.)
• Domain Validation—(Default: Enabled) Determines the optimal
transfer rate for each device on the SCSI bus and sets transfer
rates accordingly. Displays the resulting data transfer rate.
• Support Removable Disks Under BIOS as Fixed Disks—
(Default: Disabled) Determines which removable-media drives are
supported by the SCSI card BIOS. Choices are as follows:
• Disabled— No removable-media drives are treated as hard disk
drives. Software drivers are required because the drives are not
controlled by the BIOS.
• Boot Only—Only the removable-media drive designated as the
boot device is treated as a hard disk drive.
• All Disks—All removable-media drives supported by the BIOS
are treated as hard disk drives.
Caution: You may lose data if you remove a removable-media
cartridge from a SCSI drive controlled by the SCSI
card BIOS while the drive is on. If you want to be able
to remove the media while the drive is on, install the
removable-media software driver and set Support
Removable Disks Under BIOS as Fixed Disks to
Disabled.

• BIOS Support for Bootable CD-ROMs—(Default: Enabled)
When set to Enabled, the SCSI card BIOS allows the computer to
boot from a CD-ROM drive.
• BIOS Support for Int 13 Extensions—(Default: Enabled) When
set to Enabled, the SCSI card BIOS supports Int 13h extensions as
required by Plug-and-Play. The setting can be either enabled or
disabled if your system is not Plug-and-Play.
