industrial application requirements.

Advantech's PCA-6184 full-sized CPU card is designed with Intel 845E
chipset and supports socket 478 Pentium® 4/Celeron® processor (FSB
533/400MHz) up to 2.4 GHz and above. In addition to high-speed proces­sor, the PCA-6184 supports up to 2GB DDR200/DDR266 SDRAM
memory with 2 onboard DIMM socket. Ideal for high-performance and
demanding applications, it provides maximum computing power and pro­ductivity. Moreover, the PCA-6184 is built-in with ATI Rage 128 Pro
4XL and 32MB onboard VGA SDRAM. It features superior 3D perfor­mance with AGP 4X. Single or dual Intel 82559 10/100Base-T Ethernet
controller are available in the PCA-6184 series. The high reliability and
excellent performance provided by Intel 82559 Ethernet controller are
crucial for various network applications. Flexible I/O expansion ports
allow customers to optimize their need for four USB, dual LAN port, and
additional PS/2 keyboard & mouse port

A CMOS data backup is stored in the Flash memory, which protects data
even after a battery failure. Also included is a 255-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 remote management interface enables the PCA-6184 to be
managed through Ethernet when it is connected to the SNMP-1000
Remote HTTP/SNMP System Manager..

1.2 Features

1. Onboard 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. CMOS RAM backup: 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 industrial environments
which may cause soft errors. Upon such an error occurring, BIOS
will check the data, and automatically restore the original data for
booting.

7. 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.

batteries according to manufacturer's instruc­tions

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.

1.7.2 CMOS clear (J1)

The PCA-6184CPU 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 open. If you want to reset the CMOS data, set 1-2 pin for
just a few seconds, and then move the jumper back to 1-2 open. This pro-

cedure will reset the CMOS to its default setting.

1.8 System Memory

The PCA-6184 contains two sockets for 184-pin dual memory modules
(DIMMs). All these sockets accept only 2.5 V DDR200/DDR266
SDRAM. DIMMs are available in capacities of 64,128, 256, 512 MB and
1 GB. The sockets can be filled in any combination with DIMMs of any
size, giving your PCA-6184 single board computer up to 2 GB of mem-

ory.

Table 1.7: DIMM mem capacity sample calculations

Socket number 184-pin DIMM memory

1 64, 128, 256 or 512 MB or 1 GB
2 64, 128, 256 or 512 MB or 1 GB

1.8.1 Supplementary information about DIMMs

Your PCA-6184 can accept only DDR memory modules with or without
parity. Also note:

• Chips with 9 chips/side support ECC; chips with 8 chips/side do not
support ECC.

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 Pentium®
4/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® 4
processor yields much higher performance than the external cache memo­ries. The cache size in the Pentium® 4 processor is 256/512 KB, depend­ing on the type of CPU. The cache size in Celeron® processor is 128KB.

13

1.11 CPU Installation

The PCA-6184 provides socket 478 for an Pentium® 4 or Celeron® pro­cessor. 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 motherboard.

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 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.

1.11.1 Power Supply

To ensure the sufficiency of power supply for Pentium® 4 CPU card, a
auxiliary 4 pin power connector is avaliable in PCA-6184. It is strongly
suggested to use auxiliary 4 pin power connector for adequate power

supply.

2.1 Primary (CN1) and Secondary (CN2) IDE Connec­tors

CN1

CPU

You can attach up to four IDE (Integrated Drive Electronics) drives to the
PCA-6184’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 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 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.

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.

3.2 Entering Setup

Turn on the computer and check for the “patch code”. If there is a number
assigned to the patch code, it means that the BIOS supports your CPU.

If there is no number assigned to the patch code, please contact Advan­tech’s applications engineer to obtain an up-to-date patch code file. This
will ensure that your CPU’s system status is valid.

After ensuring that you have a number assigned to the patch code, press
<Del> to allow you to enter the setup.

Programming the
Watchdog Timer

The PCA-6184 is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing
comes to a standstill for any reason.
This feature ensures system reliability
in industrial standalone or unmanned
environments.

Appendix

83 Appendix A

Appendix A Programming the watchdog

timer

A.1 Programming the Watchdog Timer

The PCA-6184'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.

Note: The interrupt output of the watchdog timer is a

low level signal. It will be held low until the
watchdog timer is reset.

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).
