Chapter 1 Hardware Configuration 1
CHAPTER
Introduction
The half-size PCA-6143P comes equipped with either an 80486SX-
25, 80486SX-33, 80486DX-33, 80486DX2-50 or 80486DX2-66
CPU. Also included on-board are one serial RS-232 port, one serial
RS-232/422/485 port, an enhanced bi-directional parallel port, an IDE
hard disk drive interface, a floppy disk controller and a watchdog
timer. The watchdog timer ensures that the CPU will be reset if it
stops due to a program or EMI problem, allowing the PCA-6143P to
be used in stand-alone systems or unattended environments. The PCA-
6143P’s industrial-grade construction ensures continuous, reliable
o
operation in harsh industrial environments at temperatures up to 140 F
o
(60 C).
We designed the PCA-6143P with SBC (Single Board Computer)
applications in mind. It incorporates a single-voltage power supply
(+5 V) and a connector for PC/104 modules (Flat-panel/CRT VGA
controller or Flash/RAM/ROM disk). A built-in Flash/ROM disk
emulates a floppy disk drive of up to 1.44 MB capacity. It emulates
the 1st, 2nd, 3rd or 4th DOS drive, depending on the physical disks
installed and the DOS version. See Appendix A for details.
Built using CMOS technology, the PCA-6143P consumes very little
power. Its two SIMM (Single In-line Memory Module) DRAM
sockets accept 1 MB, 4 MB or 16MB SIMM modules for total on-
board memory of 1 to 32 MB.
You can also use this 8-layer CPU card to transform any system into a
32-bit 486 compatible computer, its all-in-one configuration freeing-
up valuable expansion slots. Its highly compact form and numerous
features make it an ideal cost/performance solution for high-end
commercial and industrial applications where high CPU speed and
low mean-time-to-repair are critical.

At the right of the card are three 32-pin sockets which hold the
memory chips for the card's Flash/RAM/ROM disk. Instructions for
installing memory chips appear in Appendix A.
Chapter 1 Hardware Configuration 7
Safety precautions
Follow these simple precautions to protect yourself from harm and
your PC from damage.
1. To avoid electric shock always disconnect the power from your PC
chassis before you work on it. Don’t touch any components of the
CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card
may damage sensitive electronic components.
3. Always ground yourself to remove any static charge before you
touch your CPU card. Be particularly careful not to touch the chip
connectors. Modern integrated electronic devices, especially CPUs
and memory chips, are extremely sensitive to static electric
discharges and fields. Keep the card in its anti-static packaging
when it is not installed in the PC and place it on a static dissipative
mat when you are working on it. Wear a grounding wrist strap for
continuous protection.
Jumper settings
This section tells how to set the jumpers to configure your card. It
gives the card default configuration and your options for each jumper.
After you set the jumpers and install the card, you will also need to
run the BIOS Setup program (discussed in Chapter 5) to configure the
serial port addresses, floppy/hard disk drive types and system operat-
ing parameters. Connections, such as hard-disk cables, appear in
Chapter 3.
Card default setting
We set the card’s jumpers at the factory for the most popular configu-
ration. If this configuration matches your needs, you may not need to
change the jumpers at all. The default configuration is as follows:
• Watchdog invokes system reset • Color display is attached
• Parallel port IRQ7, DRQ1, DACK1 • Bypass POST (JP14)
8 PCA-6143P User's Manual
How to set jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. 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” a
jumper you connect the pins with the clip. To “open” a jumper you
remove the clip. Sometimes a jumper will have three pins, labeled 1, 2
and 3. In this case you would connect either pins 1 and 2 or 2 and 3.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative
before you make any changes.
Display type (JP15)
This jumper sets the display adapter type attached to your card. If you
are using a monochrome LCD or EL screen which uses a CGA, EGA,
VGA or other color display adapter, set JP15 to color.
JP15 Setting
Open Monochrome
Closed (default) Color
Watchdog timer � system reset/IRQ15 (JP8)
When the watchdog timer activates (CPU processing has come to a
halt), it can reset the system or generate an interrupt on IRQ15. Set
jumper JP8 as shown in the following table:

Installation
This chapter gives guidelines for install-
ing your CPU card into an PC chassis
with an AT-compatible passive backplane.
For specific instructions, consult the
user’s manual for your chassis.
Before you begin, double check the
jumper settings for the card (described in
Chapter 1). This could save you a lot of
troubleshooting time later. If you are not
sure about the proper setting, contact your
local distributor or sales representative.
Chapter 2 Installation 11
CHAPTER
Warning! Disconnect all power from the chassis before you
install the CPU card. Unplug the power cord from
the wall, don’t just turn off the power switch. If
you are not sure what to do, take the job to an
experienced professional.
Caution! The electronic components on this CPU card are
very sensitive to static electric charges. Use a
grounding wrist strap to remove all static electrici-
ty before you touch any components. Place all
components on a static-dissipative mat or in a
static-shielded bag when they are not in the
chassis.
Install your CPU card as follows:
1. Remove power from the chassis and disconnect all power
cords. Follow all power-down procedures outlined in your
chassis user’s manual.
2. Remove the chassis cover, then detach the card hold-down
bracket. This bracket stretches across the top of each circuit
card to hold it securely in place.
3. Locate a free slot in the chassis. You can use any 16-bit (double
connector) slot. We suggest that you leave the maximum
amount of space between boards to improve cooling.
4. You may need to remove a block-off cover at the end of the
slot. Unscrew the cover and save the screw for use in Step 6.
5. Align the card square with the card-end guide slot and parallel
to the connector. Slide the card carefully into the connector.
6. Make sure the card is completely seated in the connector.
Screw the card I/O bracket to the case.
After you have installed the CPU card, you will need to attach the
connecting cables as described in the following chapter. Replace
the card hold-down bracket you removed in Step 2, replace the
chassis cover and power-up your system.
Dimensions for SBC (Single Board Computer) installation appear
in Chapter 1 (page 10).

Connecting
peripherals
This chapter tells how to connect
peripherals, switches and indicators to
the PCA-6143P board. You can access
most of the connectors from at 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. When
everything is done, finish installing the
card as described in Chapter 2.

The following sections tell how to make each connection. In most
cases you will simply need to connect a standard cable. If you
need to make your own cables, you can find pin assignments for
the more complicated connectors in Appendix D.
Warning! Always completely disconnect the power cord
from your chassis whenever you are working on
it. Do not make connections while the power is
on, sensitive electronic components can be
damaged by the sudden rush of power. 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. 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.
14 PCA-6143P User's Manual
Floppy drive connections
You can attach up to two floppy disk drives to the PCA-6143P's
on-board controller. You can use any combination of 5.25"
(360 KB and 1.2 MB) and/or 3.5" (720 KB and 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 floppy disk drive connectors. Each set
consists of a 34-pin flat-cable connector (usually used for 3.5"
drives) and a printed-circuit-board connector (usually used for
5.25" drives). You can use only one connector in each set. The set
on the end (after the twist in the cable) connects to the A: floppy.
The set in the middle connects to the B: floppy.
Attach the single 34-pin flat-cable connector to CN2 on the CPU
card. For help finding the connector, see Chapter 1 (page 5). Wire
number 1 on the cable is red or blue, the other wires are gray.
Make sure that the red wire corresponds to pin one on the
connector (on the right side).
Connect the A: floppy drive to the connector set on the other end
of the cable. If you are connecting a 5.25" floppy drive, line up the
slot in the printed-circuit-board (golden fingers) with the blocked-
off part of the cable connector.
If you are connecting a 3.5" floppy drive, you may have trouble
determining which pin is number one. Look for a number printed
on the circuit board indicating pin number one. Also, the connec-
tor on the floppy drive connector may have a slot. When the slot
is up, pin number one should be on the right. Check the documen-
tation that came with the drive for more information.
Next, if required, connect the B: floppy drive to the connectors in
the middle of the cable as described above.
If you need to make your own cable, you can find the pin assign-
ments for the card’s connector in Appendix D.
Chapter 3 Connecting peripherals 15
IDE hard drive connections
You can attach two IDE (Integrated Device Electronics) hard disk
drives to the PCA-6143P's internal controller. The card comes
with a 40-pin flat-cable piggyback cable. This cable has three
identical 40-pin flat-cable connectors.
Wire number 1 on the cable is red or blue, the other wires are
gray. Connect one end to connector CN1 on the CPU card. Make
sure that the red wire corresponds to pin one on the connector (on
the right side). 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, you will need to set
one as the master and one as the slave. You do this using jumpers
on the drives. If you use just one drive, you should set it 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
one on the cable should also connect to pin one on the hard drive
connector. You may have difficulty determining the pin number.
Look for a number printed on the drive circuit board. Check the
documentation that came with the drive for more information.
Connect a second drive as described above.
If you need to make your own cable, you can find the pin assign-
ments for the card’s connector in Appendix D.
Parallel Port
You would normally use the parallel port to connect the card to a
printer. The PCA-6143P includes an on-board parallel port,
accessed through a 26-pin flat-cable connector, CN3. The CPU
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
16 PCA-6143P User's Manual
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 connec-
tor CN3 on the CPU card. Wire one of the cable is red or blue, the
other wires are gray. Make sure that wire one connects to pin one
of CN3. Pin one is on the right side of CN3. For help finding the
connector, refer to Chapter 1 (page 5).
The pin assignments for the connector appear in Appendix D.
Keyboard connectors
The PCA-6143P board provides two keyboard connectors. A 5-pin
connector (J1) supports passive backplane applications. A second
6-pin mini-DIN connector (J3) on the card mounting bracket
supports single-board-computer applications. The card comes
with an adapter to convert from the 6-pin mini-DIN connector to
a standard DIN connector.
If you need to make your own adapter cable, you can find the pin
assignments in Appendix D.
External switches and indicators
Next you may want to install external switches to monitor and
control your CPU card. These features are completely optional —
install them only if you need them.
Reset switch (JP7)
You can connect an external switch to easily reset your computer.
This switch restarts your computer as if you had turned off the
power then turned it back on. Install the switch so that it closes
the two pins of JP7 when pressed (normally-open switch).
Chapter 3 Connecting peripherals 17
Power LED and keylock (JP9)
You can connect an LED to indicate when the CPU card is on. Pin
1 of JP9 supplies power to the LED and Pin 3 is the ground. For
help finding JP9, refer to Chapter 1 (page 5).
You can use a switch (or a lock) to disable the keyboard. In this
state the PC will not respond to any input. This is useful if you
don’t want anyone to change or stop a running program. Simply
connect the switch between Pins 4 and 5 of JP9. The pin assign-
ments for JP9 appear in the following table:
Power LED and keylock (JP9)
Pin Function
1LED Power (+5 V)
2No Connection
3Ground
4Keyboard lock
5Ground
Hard disk drive LED (JP1)
You can connect a LED to connector JP1 to indicate when the
HDD is active. The pin on the top is positive.
Turbo switch (JP12)
You can connect a switch across the pins of jumper JP12 to
change the CPU between Turbo and non-Turbo mode. When you
close (short) the pins, the CPU card operates at full speed. When
you leave the pins open, the card operates at slow speed for
compatibility with older software.
You can also switch the CPU back and forth between Turbo mode
and non-Turbo mode using the keyboard, but only when jumper
JP12 is open. When jumper JP12 is closed, the CPU is fixed in
Turbo mode. To switch into Turbo mode from the keyboard
simultaneously press the Ctrl, Alt and keypad plus (+) keys. To
switch into non-Turbo mode press the Ctrl, Alt and keypad minus
(-) keys.
18 PCA-6143P User's Manual
Turbo LED (JP13)
You can connect a LED indicator across jumper JP13 to indicate
when the CPU is in Turbo mode. Marks on the circuit board
indicate LED polarity (the lower pin is positive).
External speaker (JP10)
The CPU card has its own buzzer. You can also connect to the
external speaker on your computer chassis. Connect leads to
connector JP10 as shown below:

Serial Ports
The PCA-6143P offers two serial ports: one RS-232 and one
RS-232/422/485. These ports let you connect to serial devices (a
mouse, printers, etc.) or a communication network.
You can select the address for each port (3F8H [COM1], 2F8H
[COM2] or 3E8H) or disable it, through the BIOS Advanced
Setup program, covered in Chapter 5.
The card mounting bracket holds the serial port connectors. This
lets you connect and disconnect cables after you install the card.
The DB-9 connector on the top of the bracket is the RS-232 port.
The second DB-9 connector is the RS-232/422/485 port. The
following sections tell how to make RS-232 and RS-232/422/485
connections.
RS-232 connections
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. The following table

RS-232/422/485 serial port connections
RS-422 is commonly used for two-way communication between
two devices, whereas RS-485 is used for communication between
a single master and a network of slave modules.
Before you use the RS-232/422/485 port, you will need to select
RS-232, RS-422 (the default) or RS-485 mode. Set jumpers JP20,
22, 25, 26, 27, 28, 29 and 30 according to the following table:

� RS-422 signal wiring
RS-422 is used for long-distance point-to-point connections. RS-
422 originally used four wires for one-way communication (with
devices such as display terminals or printers) but was later
adopted by industry for simultaneous two-way communication by
doubling the number of wires.
Each pin on the first device connects to a corresponding device
on the second. Flow control lines manage the communication.
The following table shows pin connections:
Computer A Computer B
Pin Signal Pin Signal

� RS-485 signal wiring
In a typical RS-485 application the host device requests data from
a slave module then listens for the response. The host transmits
and receives data on the same pair of wires. Software handles the
flow control; no other wires are needed.
Pin assignments appear in the following table. Pins 1 and 4 share
the Data+ wire. Pins 2 and 3 share the Data- wire.

Power-up
After you have set the jumpers (Chapter 1),
installed SIMMs (Appendix C), installed the
card (Chapter 2) and made all external
connections (Chapter 3), you are ready to
power-up your system.
Chapter 4 Power-up 25
CHAPTER
Follow the startup procedure outlined in the manual for your
chassis.
When you start your system, the BIOS will test the hardware and
check the system configuration against the values stored in its
CMOS memory.
Since this is the first time you are starting up, the BIOS will
display an error message stating that the configuration does not
match the stored values. You should then run the BIOS setup
program as described in Chapter 5.
If the BIOS hardware diagnostic tests fail, you may see an error
message on the screen describing the problem. If the BIOS found a
problem early in the tests, you will need to determine the BIOS
POST (Power On Self Test) results by counting beeps or using a
POST card. See Appendix F for details.
The most common source of problems is incorrect jumper settings.
Double check your settings (Chapter 1) and restart the system. If
the system still has problems, see Appendix E, Maintenance and
troubleshooting.
There are three methods you can use to restart your system after it
is turned on:
1. Switch the power off, then on again
2. Reboot the system. Using the keyboard, simultaneously press
the CTL, ALT and DEL keys
3. Depress the optional reset switch
Use of each of these methods will erase data from the system
RAM memory. If you can, save any data stored in memory to a
hard or floppy disk before you reset your system.

This chapter describes the card’s diagnos-
tic tests and how to set BIOS configura-
tion data. BIOS POST (Power On Self
Test) test codes appear in Appendix F.
Chapter 5 BIOS diagnostics and setup 27
CHAPTER
POST (Power On Self Tests)
Whenever you start up your system, the CPU card runs a series of
programs stored in an on-board ROM chip. These programs are
divided into two stages:
System test and initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors. Non-fatal error messages
usually appear on the screen along with the following instructions:
press to RESUME
Write down the message and press the F1 key to continue the
bootup sequence. Non-fatal error messages appear in Appendix F.
If the routines encounter a fatal error, they will stop the tests and
output a message indicating which test failed. If the fatal error
comes before the screen device initializes, the card will indicate
the error code through a series of beeps. Error beep codes also
appear in Appendix F.
System configuration verification
These routines check the current system configuration against the
values stored in the card’s CMOS memory. If they don’t match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in
memory.
28 PCA-6143P User's Manual
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The PCA-6143P’s CMOS memory has integral lithium battery
backup. The battery backup should last ten years in normal
service, but when it finally runs down, you will need to replace the
complete unit. Contact your sales representative or distributor for
details.
Running the setup program
Normally, the only routine visible on the screen will be the
memory test. The following figure shows the screen as it appears
while the tests are occurring.

before you contact your dealer for technical support.
To “freeze” the screen so that you can write down the codes,
power-on the system and hold down a key on the keyboard. This
will cause a “Keyboard Error” message to appear on the screen
and the system will wait for you to press the key. After you

Flash/ROM disk
Appendix A Flash/ROM disk 47
APPENDIX
The PCA-6143P features an internal Flash/ROM disk drive. This
drive emulates a floppy disk drive by using solid-state memory
chips (Flash or EPROM) to store programs and data instead of the
magnetic particles on the mechanical drive’s disk. The Flash/ROM
disk offers much faster access times than a floppy or hard disk and
greatly increased reliability in harsh environments.
The Flash/ROM disk works by modifying the BIOS INT-13 disk
I/O routine on boot-up. The routine then translates read and write
commands to the disk so that they will correctly access the
memory chips. You don’t need any special drivers. You simply set
the drive to act as a DOS drive (e. g. A:, B:, C: or D: - 1st, 2nd, 3rd
or 4th floppy disks) and use standard DOS commands (COPY,
DIR, etc.) to manipulate your data.
Before you use the Flash/ROM disk, you will need to enable it
with the BIOS Advanced Setup Program, discussed in Chapter 5.
Memory devices
The Flash/RAM/ROM disk supports the following memory
devices, or their equivalents:
• 27C010 128 KB x 8 EPROM
• 27C040 512 KB x 8 EPROM
• 28F010 128 KB x 8 +12 V Flash Memory (AMD/INTEL)
• 29C010 128 KB x 8 +5 V Flash Memory (ATMEL only)
• 29C040 512 KB x 8 +5 V Flash Memory (ATMEL only)
If you use EPROM, files on the disk are read only. You will need
an external programmer to load your program and data files on the
EPROMs.
If you use +5 V Flash memories (29C010 or 29C040) for the solid
state disk, you can read or write data just like a floppy disk; you
need not use an external programmer. If you use +12 V Flash
memories (28F010) you will still need an external programmer to
write data.
48 PCA-6143P User's Manual
Drive capacity
The size of the emulated drive depends on the size and number of
the chips you install. For example, if you install three 512 KB
chips, you will have 3 x 512 KB = 1.536 MB, equivalent to a 1.44
MB floppy.
You will need to set jumpers JP19, JP23 and JP24 to match the
type (Flash, RAM or ROM) and size (128 KB or 512 KB) of the
devices you use. All the devices must be the same type and size.
The following tables shows the size and number of devices you
will need for each size emulated disk. It also shows the corre-
sponding settings of jumpers JP19, JP23(Flash/RAM/ROM) and
JP24 (128 KB/512 KB).

Drive configuration
Before you activate the Flash/RAM/ROM drive (using the BIOS
Advanced Setup program), you will need to set the drive's I/O and
memory addresses to avoid conflicts with other plug-in cards. You
will also need to set the DOS drive designation to be used by the
Flash/RAM/ROM drive. DIP switch SW1 controls each of these
settings, as described in the following sections:
Appendix A Flash/ROM disk 49
�I/O address selection (SW1)
Positions 1 and 2 on DIP switch SW1 control the disk's I/O
address.
Position 1 Position 2 I/O address (HEX)

On Off 240-241
On On 280-281
�Memory address selection (SW1)
Positions 3 and 4 on SW1 control the Flash/ROM disk’s memory
address. If you select "Disabled", the disk will not function.
Position 3 Position 4 Memory address (HEX)
Off Off Disabled
Off On D2000 to D3FFF
On Off D6000 to D7FFF
On On DA000 to DBFFF
�Drive emulated (SW1)
Positions 5 and 6 of SW1 control the DOS drive emulated by the
Flash/RAM/ROM disk: 1st, 2nd, 3rd or 4th.
Position 5 Position 6 Drive
Off Off 4th
Off On 3rd
On Off 2nd
On On 1st
The actual drive letter assigned by DOS to the Flash/RAM/ROM
disk depends on the floppy or hard disks installed in the system
and the DOS version.
50 PCA-6143P User's Manual
Drive Selection
DOS 5.0 (and later)
Floppy disks
The Flash/ROM disk will replace the corresponding floppy disk.
For example, if you have a single floppy disk (drive A:) and assign
the Flash/ROM disk to be the 1st drive (both switches 5 and 6 are
on), any drive operations directed at drive A: will go to the Flash/
ROM disk. This floppy drive will then be assigned the next free
drive designation. The example below illustrates this.
Hard disks
The Flash/ROM disk will not replace corresponding hard disks.
Instead, DOS will assign the Flash/ROM disk to the next free drive
designation. For example, if you have a single hard disk (drive C:)
and assign the Flash/ROM disk to be the 3rd drive (switch 5 on,
switch 6 off), the Flash/ROM drive will become drive D:. If you
have two hard disks, the Flash/ROM drive will become drive E:.
Example 1
You install the Flash/ROM disk as drive A: (both switches 5 and 6
are on).

Booting from the Flash/RAM/ROM disk
If you wish to have the system boot from the Flash/RAM/ROM
disk, simply set positions 5 and 6 on SW1 for the 1st FDD. Copy
your application files to the disk along with the standard system
files required to boot (command.com, io.sys, autoexec.bat, etc).
The next time you start the system, it will boot from the solid state
disk.
Inserting memory devices
After you’ve set all the jumpers and switches on the PCA-6143P,
insert the appropriate memory devices into the card’s sockets.
Remember that you will need to program EPROMs before you
insert them.
1. Make sure that the pins of the memory chips are perpendicular
to the case and both rows are parallel to each other. Many times
the chips come with the pins spread out slightly. Place the chip
on a table top and carefully bend each line of pins together
until they point directly down.
2. Insert each chip. Align the chips so their pins are perpendicular
to the connector and the semicircular notch on the end of the
chip matches the notch on the end of the socket. There will
probably be a gap between the chip body and the socket when
it is fully seated – do not push too hard!
52 PCA-6143P User's Manual
Formatting the Solid State disk
If you use Flash memory or SRAM, it is advisable to format the
Flash/SRAM disk before copying files to it. The DOS command is
as follows:
FORMAT drv: /U ...
where drv = solid state disk drive A, B, C etc.
File copy utility
The utility program COOKROM.EXE, included on the card's
utility disk, splits the files on a diskette into a series of binary files.
You can then use an external programmer to copy the files to
EPROM or +12 V Flash memory chips. It produces up to three
files, depending on the size of the source files.
Using a memory manager
(EMM386.EXE)
If you are using an extended or expanded memory manager (such
as EMM386 or QEMM386), you will need to configure it to avoid
the addresses used by the Flash/RAM/ROM disk (set by positions
1 and 2 of SW1). Otherwise, the memory manager will attempt to
use these addresses, causing unreliable operation.
For example, the line in your CONFIG.SYS file that invokes
EMM386, the DOS memory manager, might be the following:
DEVICE=EMM386.SYS X=D600-D7FF
This excludes a 8 KB range for the card from D6000 to D7FFF
(the default addresses).
If you are using expanded memory, you will need to make sure
that the memory manager is not putting the page frame in the
disk's addresses. For example,
DEVICE=EMM386.EXE X=D600-D7FF FRAME = D800
You should also make sure that the disk's memory address is not
shadowed in the BIOS.

Programming the
watchdog timer
The PCA-6143P is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for whatever reason. This
feature ensures system reliability in
industrial stand-alone and unmanned
environments.
Appendix B Programming the watchdog timer 55
CHAPTER
Programming the watchdog timer
If you decide to program the watchdog timer, you must write a
program which reads I/O port address 443 (hex) at regular
intervals. The first time your program reads the port, it enables the
watchdog timer. After that your program must read the port at time
intervals less than 2.0 seconds (as set in the BIOS), otherwise the
watchdog timer will activate and reset the CPU or generate an
interrupt on IRQ15. When you want to disable the watchdog timer,
your program should read I/O port 043 (hex).
If CPU processing comes to a standstill because of EMI or a
software bug, your program's signals to I/O port address 443 to the
timer will be interrupted. The timer will then automatically reset
the CPU or invoke an IRQ, and data processing will continue
normally.
The following program shows how you might program the
watchdog timer in BASIC:
10 REM Watchdog timer example program
15 REM Watchdog timer interval set to 2 sec in BIOS
20 X=INP(&H443) REM Enable and refresh the watchdog
30 GOSUB 1000 REM Task #2, takes 2 sec to complete
40 X=INP(&H443) REM Refresh the watchdog
50 GOSUB 2000 REM Task #2, takes 2 sec to complete
60 X=INP(&H043) REM Disable the watchdog
70 END
1000 REM Subroutine #2, takes 2 seconds to complete

Upgrading
This appendix gives instructions for
increasing the capabilities of your CPU
card. It covers:
� DRAM memory installation (SIMMs)
� CPU installation and upgrading
� Installing PC/104 modules
Appendix C Upgrading 57
APPENDIX
Installing DRAM (SIMMs)
You can install anywhere from 1 MB to 32 MB of on-board
DRAM memory using 256 KBx36, 1 MBx36 or 4 MBx36 SIMMs
(Single In-line Memory Modules). Access time should be 80 ns or
less.
Memory installs in two 72-pin SIMM sockets. See the figure on
page 5 for help identifying the banks. You must fill both sockets,
and both SIMMs must be of the same capacity, i. e. you cannot
mix 256 KB SIMMs with 1 MB SIMMs. The following table
shows the memory size for different SIMM capacities:
System memory configuration SIMM size Pcs
1 MB 256 KB x 36 1
2 MB 256 KB x 36 2
4 MB 1 MB x 36 1
8 MB 1 MB x 36 2
16 MB 4 MB x 36 1
32 MB 4 MB x 36 2
The procedure for installing SIMMs appears below. Please follow
these steps carefully.
Warning! Completely disconnect power from the system
before you install SIMMs. Remove the CPU card
from the chassis. .
Caution! Properly ground yourself (we recommend a
grounding wrist strap) before you touch the CPU
card or SIMMs. Both are very susceptible to
damage from static discharge. Place the card
and SIMMs on a static-dissipative surface or into
a static-shielding bag when they are not installed.
1. Locate the CPU card�s memory banks, shown in the figure in
Chapter 1 (page 5).
58 PCA-6143P User's Manual
2. Install the SIMM cards. Install each SIMM so that its chips
faces the CPU and its gold pins point down into the SIMM
socket.
3. Slip each SIMM into a socket at a 45 degree angle and careful-
ly fit the bottom of the card against the connectors.
4. Gently push the SIMM into a perpendicular position until the
clips on the ends of the SIMM sockets snap into place.
5. Check to ensure that each SIMM is correctly seated and all
connector contacts touch. The SIMM should not move around
in its socket.
CPU installation and upgrading
This section tells how to install or upgrade the card’s CPU. You
can upgrade your PCA-6143P to a higher powered 486 CPU at any
time. Simply remove the old 486 CPU, install the new and set the
jumpers for the CPU type and speed.
Warning! Disconnect all power from the chassis before you
remove or install the CPU card. Follow the
power-down procedure outlined in the manual for
your chassis. Unplug the power cord from the
wall, don’t just turn off the power switch. If you
are not sure what to do, take the job to an
experienced professional.
Caution! The electronic components on this CPU card are
very sensitive to static electric charges. Use a
grounding wrist strap to remove all static electrici-
ty before you touch any components. Place all
components on a static-dissipative surface or in a
static-shielded bag when they are not in the
chassis.
1. Disconnect power from the chassis and remove the CPU card.
Follow the instructions in the user’s manual for your chassis.
You will also need to disconnect everything you connected in
Chapter 3, Connections.
Appendix C Upgrading 59
2. If you are upgrading the CPU, remove any existing CPU from
the socket. (See Chapter 1 for help locating the socket.) The
old chip may be difficult to remove. You may find spray chip
lubricant (designed for pin-grid-array devices, PGAs) and a
chip puller helpful (available at electronics hobbyist’s supply
stores).
3. Plug in the new CPU into the empty socket. Follow the
instructions that came with the CPU or math coprocessor. If
you have no instructions, do the following: Lubricate the pins
of the CPU. Use lubricant designed for use with PGA devices.
This will make the new CPU slide in MUCH easier and reduce
the chance of bending pins or other damage. Next, carefully
align the CPU so it is parallel to the socket and the notch on the
corner of the CPU matches with the notch on the inside of the
socket. Carefully slide in the CPU. There will probably be a
gap between the CPU and the connector when it is fully seated
� do not push too hard!
4. Switch jumpers JP2, JP3 and JP31 to match the new CPU
according to the following table:
JP2 JP3 JP31
SX-25 Off 1-2 Closed
SX-33 Off 1-2 Closed
DX-25 2-3 2-3 Closed

This appendix describes the general
maintenance that your CPU card requires
to ensure reliable operation. It then gives
some solutions to common card trouble-
shooting problems.
Appendix E Maintenance and troubleshooting 75
APPENDIX
General maintenance
As with any electronic equipment, an adequate maintenance
program will ensure reliable performance.
In general terms, maintenance includes periodic inspection of the
card and peripherals to ensure that they are clean and free from
signs of dirt, dust, wear and stress.
Warning! Always remove power from the complete system
before installing the CPU card. Follow all power-
down procedures outlined in the chassis user’s
manual. To avoid injury to personnel, disconnect
the power cord from the power source. Only
qualified, experienced electronics personnel
should access the interior of the chassis.
Caution! Never allow moisture or condensation to come in
contact with the PCA-6143P components or
cables and connectors. Damage to sensitive
components may occur.
Inspect all cables and connectors to verify that they are securely
fastened to their connecting components. Worn or stressed cables
or connectors should be replaced.
All peripheral equipment used with the PCA-6143P should be
properly maintained. Malfunctioning equipment should be
immediately replaced to prevent damage to the CPU.
76 PCA-6143P User's Manual

troubleshooting guide
PROBLEM
Will not boot up
SOLUTION
Make sure that all cards on the passive backplane are firmly seated
in their slots. Clean the pins on the cards and slot connectors on
the passive backplane if necessary.
Check the DC output of the power supply. All required voltages
(+5 V, + 12 V, etc.) should be present. The +5 V output should be
within the range 4.75 V to 5.25 V.
Make sure that the DRAM modules are correctly inserted into their
sockets and have the correct access time (usually 80 nsec or less)
Check that the CMOS is correctly set up. Check the HDD, FDD,
wait states, error hold, etc.
Make sure the add-on cards are OK. Remove or change add-on
cards and test again.
Ensure that the math co-processor is properly inserted in its socket.
Check the connections between the video card and monitor. Check
display adjustments, especially when using LCD displays. The
system may be booting up, but not displaying on the screen.
If you are booting from a floppy disk drive, make sure the floppy
is bootable. If booting from a hard drive, make sure that it is pro-
perly formatted for your DOS version. New disks must first be
partitioned (with FDISK) and formatted with FORMAT).
Check HDD and FDD cable connections. Make sure that the
floppy drive is designated drive A: (the end connector on the FDD
cable), and that the hard disk is designated drive C: (the end
connector on the HDD cable).
Check connections for the reset, keylock and power LED wires.
Remove completely or adjust the value of the terminating resistor
on your backplane.
Appendix E Maintenance and troubleshooting 77
Check for and remove viruses. The boot sector and partition table
on your HDD may be damaged.
PROBLEM
CMOS setup loss
SOLUTION
Make sure that your application software does not write to CMOS
data addresses.
PROBLEM
System hangs after working for a short time (about 20 minutes)
SOLUTION
Make sure the power switch is set to correct input range (110 or
220 V ). If the correct range is set, check the quality of the input
AC
power. It should be stable and between 90 and 120/200 and
240 V . PC equipment should not be connected to the end of a
AC
power trunk line. Next, check the output of the power supply. The
+5 V supply should be between 4.75 and 5.25 V .
DC DC
o o
Make sure the temperature of the case is less than 60 C (140 F). If
necessary, clean the air filter and backplane.
Check that the SIMM DRAM modules have an access time of
80 nsec or less.
PROBLEM
Serial Port Failure
SOLUTION
Check cable connections between the PC and the remote terminal
equipment. Make sure that the remote terminal equipment is
functioning properly.
Check COM port assignment.
When using standard C, Pascal or BASIC serial port commands,
make sure that either the port�s DTR/DSR and RTS/CTS lines are
looped back (shorted together in the connector), or the COM port
78 PCA-6143P User's Manual
is set to loop back mode. Test using diagnostic software such as
Checklt or QAPlus.
The RS-232 interface relies on good grounding for reliable
operation. Check that all equipment has a good connection to
ground, and that the ground potential is the same at both locations.
PROBLEM
Parallel Port Failure
SOLUTION
Make sure the printer cable is connected correctly.
Make sure that the printer is on-line and self-tests OK.
Make sure that application software is set correctly.
PROBLEM
FDD works incorrectly
SOLUTION
Check the connections between the CPU card and FDD.
Clean the magnetic head of the FDD. Make sure you are using
diskettes of the proper capacity and format.
Check that the FDD type is correctly set in CMOS.
Reset the BIOS to the default setting and try again.
Make sure the super I/O configuration is setup correctly.
PROBLEM
HDD works incorrectly
SOLUTION
Check cable connections. Check that the master/slave jumpers are
properly set. The boot drive should be the master.
Make sure the HDD type is correctly set in CMOS. Reset system
setup to BIOS default settings and try again.
Check for and remove viruses. The boot sector and partition table
on your HDD may be damaged.
Appendix E Maintenance and troubleshooting 79
Make sure the super I/O configuration is setup correctly.
Check for bad sectors on the hard disk (using a program such as
Norton Disk Doctor). This is a common problem with Conner
HDDs. If bad sectors are found, reformat the HDD.
PROBLEM
Add-on cards work incorrectly
SOLUTION
Check jumper and switch settings of add on cards.
Make sure that the card is firmly seated in its slot. Clean the pins
on the card and the passive backplane connector if necessary.
Make sure the bus speed setting in CMOS setup is 8 MHz. Check
that the shadow RAM and EMS settings in CMOS do not conflict
with the add-on card�s firmware and I/O addresses.
Remove (or replace) the terminating resistors on the passive
backplane and test again. These resistors are especially important
for high speed add-on cards.
PROBLEM
Real-time clock is not accurate
SOLUTION
Under standard conditions the DS-12887 is accurate to within two
minutes per month.
Make sure the application software you are using does not
interrupts the RTC and/or writes improper data to the RTC.
PROBLEM
Software
SOLUTION
Make sure that the memory, system configuration, display and
HDD space meet the minimum requirements of the software.
Make sure the software is properly installed.
Check for and remove viruses.

AMI BIOS error codes
This appendix lists the codes generated by
the AMI BIOS if it encounters a hardware
error during its POST (Power On Self
Test) routines.
Appendix F AMI BIOS error codes 81
APPENDIX
Whenever you start up your system, the CPU card runs a series of
programs to test and initialize board hardware. If the routines
encounter an error in during the tests, you will either hear a few
short beeps or see an error message on the screen. There are two
kinds of errors: fatal and non-fatal. The system can usually
continue the boot up sequence with non-fatal errors. Non-fatal
error messages usually appear on the screen along with the
following instructions:
Press to RESUME
Write down the message and press the F1 key to continue the
bootup sequence. The cure for most non-fatal error messages is
simply to run the BIOS SETUP program, discussed in Chapter 5.
If the routines encounter a fatal error, they will stop the tests and
output a message indicating which test failed. If the fatal error
comes before the screen device initializes, the card will indicate
the error code through a series of beeps.
You can also determine the number of the test that failed by
reading the LED indicators on the top of the PCA-6143P board.
Please make a note of any BIOS error codes before you contact
Advantech for technical support.
Beep codes
Beep codes indicate fatal errors through a series of audible tones
output through the card’s buzzer or a speaker. The number of
beeps indicates the error, as shown in the following table:
BIOS error codes � Beep codes
Beeps Meaning
1 Refresh failure – The card's memory refresh circuitry is faulty.
2 Parity error – A parity error was detected in the base memory
(the first block of 64 KB) of the system.
3 Base 64 KB memory failure – A memory failure occurred within
the first 64 KB of system memory.
4 Timer not operational – Timer #1 on the card has generated an
error.
82 PCA-6143P User's Manual
Beeps Meaning
5 Processor error – The card's CPU has generated an error.
6 8042 Gate A20 failure – The keyboard controller (8042)
contains the Gate A20 switch which allows the CPU to operate
in protected mode. This error message means that the BIOS is
not able to switch the CPU into protected mode.
7 Processor exception interrupt error – The CPU has generated
an exception interrupt
8 Display memory read/write error – The system video adapter is
either missing or has faulty memory. Note: This is not a fatal
error.
9 ROM checksum error – The ROM checksum value does not
match the value encoded in the BIOS.
10 CMOS shutdown register read/write error – The shutdown
register for the CMOS memory has failed
Non-fatal error messages
Following are descriptions of the BIOS’s non-fatal error messages:
8042 Gate A20 error
The gate-A20 portion of the keyboard controller (8042) has failed
to operate correctly. Replace the 8042 chip or the keyboard.
Address line short

C: drive failure
The BIOS cannot get any response from hard disk drive C:. You
may need to replace the disk.
CMOS battery state low
The battery used to stored the CMOS values appears to be low.
CMOS checksum failure
After the CMOS values are saved, a checksum value is generated
to provide for error checking. If the previous value is different
from the value currently read, this message appears. To correct this
error, you should run the BIOS Setup Program.
CMOS display type mismatch
The type of video stored in CMOS does not match the type
detected by the BIOS. Run the BIOS Setup Program to correct this
error.
CMOS memory size mismatch
If the BIOS finds the amount of memory on your motherboard to
be different from the amount indicated in the CMOS it generates
this message. Run the BIOS Setup Program to correct this error.
CMOS system options not set
The values stored in CMOS are either corrupt or nonexistent. Run
the BIOS Setup Program to correct this error.
CMOS time and date not set

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
