Chapter 1 Hardware Configuration 1
Introduction
The PCA-6151 is a cost-effective, all-in-one single board Pentium
CPU card which can release Pentium’s full potential and provide
unprecedented performance compared to current 64-bit processor
board. The PCA-6151 offers all the functions of an industrial
computer on a single board, half-size CPU card. This card uses a
Pentium, AMD K5 CPU or Cyrix M1 and can have up to 64 MB
DRAM. It also supports PB-SRAM 2nd level cache size from 256KB
to 512KB through an on board COAST module.
The PCA-6151 utilizes a two-chip solution, allowing on board DRAM
to be shared with the built-in VGA controller. In this configuration
the chipset always acts as the arbiter between memory bus masters.
This system insures efficient memory allocation while substantially
reducing the overall system cost.
On-board features include one RS-232 port, one RS-232/422/485 port,
one multi-mode parallel (ECP/EPP/SPP) port, a floppy drive controller and a keyboard & PS/2 mouse interface. The built-in high speed
PCI IDE controller supports both PIO and bus master modes. Up to
two IDE devices can be connected, including large hard disks,
CD-ROM drives, tape backup drives and other IDE devices.
The PCA-6151 also features power management to minimize power
consumption. It complies with the ”Green Function” standard and
supports three types of power saving features: Doze mode, Standby
mode and Suspend mode. A watchdog timer can automatically reset
the system or generate an interrupt should the system stop due to a
program bug or EMI.

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 on
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 antistatic packaging
when it is not installed in the PC, and place it on a static
dissipative mat when you are working with it. Wear a grounding
wrist strap for continuous protection.
6 PCA-6151 User's Manual
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 3) to configure the
serial port addresses, floppy/hard disk drive types and system
operating parameters. Connections, such as hard disk cables, appear in
Chapter 2.
For the locations of each jumper, see the board layout diagram
depicted earlier in this chapter.
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 connect either pins 1 and 2 or 2 and 3.

Installing DRAM (SIMMs)
On the left end of the card (away from the mounting bracket) are the
two SIMM(Single In-line Memory Module) sockets that hold the
card’s DRAM memory. See the board layout diagram depicted earlier
in this chapter.
You can use anywhere from 1 MB to 64 MB of DRAM with your
PCA-6151. The card provides two 72-pin SIMM sockets that accept
from 1 to 32 MB each. The sockets (numbered from 1 to 2) are
arranged into two banks.

CHAPTER
Connecting
Peripherals
This chapter tells how to connect
peripherals, switches and indicators to the
PCA-6151 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.

The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable.
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-6151 User's Manual
Enhanced IDE connectors (CN4)
You can attach two IDE (Integrated Device Electronics) drives to
the PCA-6151’s internal controller. The PCA-6151 CPU card has
an EIDE connector, CN4.
Wire number 1 on the cable is red or blue, the other wires are gray.
Connect one end to connector CN4 on the CPU card. Make sure
that the red (or blue) wire corresponds to pin 1 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 by setting the
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 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 drive as described above on CN4.
VGA display connector (CN12)
The PCA-6151 provides a VGA controller for high resolution
VGA interface. CN12 is a DB-15 connector for VGA monitor
input.
Chapter 2 Connecting Peripherals 15
Floppy drive connector (CN8)
You can attach up to two floppy disk drives to the PCA-6151’s
on-board controller. You can use any combination of 5.25"
(360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 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.
Parallel port connector (CN5)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6151 includes an on-board parallel port,
accessed through a 26-pin flat-cable connector, CN5. 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 CN5 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 CN5.
Pin 1 is on the right side of CN5.
16 PCA-6151 User's Manual
Keyboard & PS/2 mouse connectors (CN14)
The PCA-6151 board provides a keyboard connector. A 6-pin
mini-DIN connector (CN14) 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 and to a PS/2 mouse connector.
Reset switch (J14)
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 J14.
Hard disk drive LED (CN6)
You can connect a LED to connector CN6 to indicate when the
HDD is active. Marks on the circuit board indicate LED polarity.
Serial Ports
The PCA-6151 offers two serial ports: COM1 in RS-232, COM2
in 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 ( For example,3F8H
[COM1], 2F8H [COM2]) or disable it, using the BIOS Advanced
Setup program, covered in Chapter 3.
The card mounting bracket holds the serial port connector for the
one port, and the parallel port and serial port adapter kit (supplied
with the card) holds the connector for the other port. This lets you
connect and disconnect cables after you install the card. The DB-9
connector on the bottom of the bracket is the first RS-232 port,
COM1. The DB-9 connector on the adapter kit is the second serial
port, COM2.

Virus Warning
During and after the system boots 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 run the anti-virus program to locate the problem.
If Virus Warning is Disabled, no warning message will appear if
anything attempts to access the boot sector or hard disk partition.
CPU Internal Cache/External Cache
Depending on the CPU/chipset design, these options can speed up
memory access when enabled.
Quick Power On Self Test
This option speeds up the Power-On Self Test (POST) conducted
as soon as the computer is turned on. When enabled, BIOS
shortens or skips some of the items during the test. When disabled,
normal POST procedures assumes.
Boot Sequence
This function determines the sequence in which the computer will
search the drives for the disk operating system (i.e. DOS). The
default value is “A, C”.
A,C System will first search the FDD, then the HDD.
C,A System will first search the HDD, then the FDD.
C, CDROM, A System will search the HDD, CDROM, then the FDD.
CDROM, C, A System will search the CDROM, HDD, then the FDD.
C only System will only search the HDD.
Boot Up Floppy Seek
During POST, BIOS will determine if the floppy disk drive
installed is 40 or 80 tracks. 360 KB type is 40 tracks while 720
KB, 1.2 MB, and 1.44 MB are all 80 tracks.
Enabled BIOS searches the floppy drive to determine if it is 40 or 80
tracks. Note that BIOS cannot differentiate 720 KB, 1.2 MB, and 1.44 MB
type drives as they are all 80 tracks.

APPENDIX
Programming the
Watchdog Timer
The PCA-6151 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 standalone and unmanned
environments.
Appendix A Programming the Watchdog Timer 33
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). The output data
is a value timer. You can write from 01 (hex) to 3E (hex), and the
related timer is 1 sec. to 63 sec.
After data entry, your program must refresh the watchdog timer by
rewriting the I/O port 443 (hex) while simultaneously setting it.
When you want to disable the watchdog timer, your program
should read I/O port 043 (hex).
The following is an example of a program for the watchdog timer:
Step 1 Out 443h data REM Start and reset the watchdog timer
Step 2 Your application task #1
Step 3 Out 443h, data REM Reset the timer
Step 4 Your application task #2
Step 5 Out 443h, data REM Reset the timer
Step 6 in 043h, REM Disable the watchdog timer
Data Values
01 1 sec.
02 2 sec.
03 3 sec.
04 4 sec.
3E 63 sec.

Appendix B Upgrading 35
Installing PC/104 modules (CN2,CN3)
The PCA-6151 card’s PC/104 connector lets you attach PC/104
modules. These modules perform the functions of traditional
plug-in expansion cards, but save space and valuable slots.
Advantech modules include:
• PCM-3110 PCMCIA module
• PCM-3520 Flat Panel/CR T VGA module
• PCM-3810 Solid State Disk module
• PCM-3820/C High density Solid State Disk modules
• PCM-3610 Isolated RS-232/422/485 module
• PCM-3640 4 Port RS-232 module
• PCM-3290 GPS module
• PCM-3660 Ethernet module
• PCM-3718 30 KHz A/D module
• PCM-3724 48-channel DIO module
PC/104 modules are produced by over a dozen manufacturers, and
the PC/104 form factor is being advanced as an appendix to the ISA
bus standard.
If you want to make your own PC/104 module, make sure that your
module dimensions are correct. A PC/104 breadboard module
(PCM-3910) is also available. For further information, contact your
Advantech distributor or sales representative.
