Chapter 1 Hardware Configuration

1.1 Introduction

Advantech's PCA-6186 full-size CPU card is designed with Intel 845G
chipset and supports socket 478 Pentium 4/Celeron processor (FSB 400/
533MHz) up to 2.4GHz and above. In addition to high-speed processor,
PCA-6186 supports up to 2GB DDR memory with 2 DIMM socket on
board. It provides maximum computing power and productivity which is
ideal for high-performance demanding application. Intel's 845G inte­grated VGA provides superior 3D performance with AGP 4X. Dual Intel
82551/82562 10/100Base-T Ethernet controller or dual Intel 82540 10/
100/1000Base-T Ethernet controller are available in PCA-6186 series.
The high reliability and excellent performance provided by Intel Ethernet
controller are crucial for various network applications. PCA-6186 also
offers an exclusive feature of USB 2.0 and which provides high speed
data transfer rate up to 480 Mb/sec. In addition to onboard two USB con­nectors, flexible I/O expension board allows customer to optimize their
need for additional four USB port.

A backup of CMOS data 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-6186 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-6186 User’s Manual 2

1.2 Features

1. 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.

2. Temperature monitoring and alert: To prevent system overheat-
ing and damage, the CPU card supports processor thermal sensing
and auto-protection.

3. Voltage monitoring and alert: 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.

4. 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 Section 3.7.8 Soft-off by PWR-BTN).
Regardless of the setting, pushing the power button for more than 4
seconds will enter the Soft-Off mode.

5. 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.

6. 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.

7. 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.

8. 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.

9. More:

• 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 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 rec­ommended by the manufacturer. Discard used
batteries according to manufacturer's instruc­tions.

1.7 Jumper Settings

This section provides instructions on how to configure your card by set­ting the 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
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

PCA-6186 User’s Manual 10

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-6186 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 1-2

closed. This procedure will reset the CMOS to its default setting.

1.7.3 Watchdog timer output (J2)

The PCA-6186 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-6186 will recover from a software failure or an EMI
problem. The J2 jumper settings control the outcome of what the com­puter will do in the event the watchdog timer is tripped.

Note: The interrupt output of the watchdog timer is a

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

1.8 System Memory

The top-left edge of the PCA-6186 contains two sockets for 184-pin dual
in-line memory modules (DIMMs). Both two sockets use 3.3 V unbuf­fered synchronous DRAMs (DDR SDRAM). DIMMs are available in
capacities of 64, 128, 256, 512 MB, or 1 GB. The sockets can be filled in
any combination with DIMMs of any size, giving your PCA-6186 single
board computer between 64 MB and 2 GB of memory. Use the following

table to calculate the total DRAM memory within your computer:

1.8.1 Sample calculation: DIMM memory capacity

Suppose you install a 512 MB DIMM into your PCA-6186's socket 1 and
a 512 MB DIMM into sockets 2. Your total system memory is 1 GB, cal-

culated as follows:

Table 1.6:

Total memory 1 GB

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®
socket 478 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 processor yields much higher performance than the external
cache memories. The cache size in the Intel ® Pentium ® 4 processor is
512 KB. In the Celeron CPU, the cache size is 128KB.

Connecting
Peripherals

This chapter tells how to connect
peripherals, switches, and indicators to
the PCA-6186 board.

15 Chapter 2

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 chasis, you may need to partially remove the card to make all
the connections.

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

CN1

CN2

You can attach up to four IDE (Integrated Drive Electronics) drives to the
PCA-6186’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.

PCA-6186 User’s Manual 16

2.3 Floppy Drive Connector (CN3)

CN3

You can attach up to two floppy disk drives to the PCA-6186's onboard
controller. You can use 3.5" (720 KB, 1.44 MB) drives.

The card comes with a 34-pin daisy-chain drive connector 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)

CN4

The parallel port is normally used to connect the CPU card to a printer.
The PCA-6186 includes an onboard parallel port, accessed through a 26­pin 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.

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
1 of the cable is red or blue, and the other wires are gray. Make sure that
wire 1 corresponds to pin 1 of CN4. Pin 1 is on the upper right side of
CN4.

17 Chapter 2

2.5 USB Ports (CN6, CN31, and CN32)

The PCA-6186 provides up to six ports of USB (Universal Serial Bus)
interface, which gives complete Plug & Play and hot swapping for up to
127 external devices.The USB interface complies with USB Specification
Rev. 2.0 support transmission rate up to 480 Mbps and is fuse-protected.
The USB interface can be disabled in the system BIOS setup.

2.6 VGA Connector (CN7)
