Safety precautions
Follow these simple precautions to protect yourself from hard and
your PC from damage:
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.
8 PCA-6148/6148L 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.

The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable.
Safety Precautions
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.
20 PCA-6148/6148L User's Manual
IDE connectors (CN3)
You can attach two IDE (Integrated Device Electronics) drives to
the PCA-6148/6148L's internal controller. The PCA-6148/6148L
CPU card has an EIDE connector, CN3.
Wire number 1 on the cable is red or blue, the other wires are gray.
Connect one end to connector CN3 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 CN3.
Flat panel interface connection (CN1)
Flat panel display connector (PCA-6148 only)
CN1 consists of a 44-pin, dual-in-line header. The PCA-6148
provides a bias control signal on CN1 which can be used to control
the LCD bias voltage. It is recommended that the LCD bias
voltage (+5V) and panel video signals are stable. Under normal
operation the control signal (ENAVEE) is active high. When the
PCA-6148/6148L's power is applied, the control signal is low until
just after the relevant flat panel signal is present.
Configuration of the VGA interface is done completely via the
software utility. You don't have to set any jumpers. Refer to
Chapter 4 for software setup details.
Chapter 2 Connecting peripherals 21
Floppy drive connector (CN4)
You can attach up to two floppy disk drives to the PCA-6148/
6148L's on-board controller. You can use any combination of
5.25"
(360 KB and 1.2 MB) and/or 3.5" (720 KB, 1.44 MB and 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-6148/6148L 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.

Keyboard & PS/2 mouse connectors (CN14,
CN16)
CN16, the card's keyboard connector, is a 6-pin mini-DIN connec-
tor on the card mounting bracket. The PCA-6148/6148L also
comes with an adapter to convert to a standard DIN connector and
to a PS/2 mouse connector.
CN16
The PCA-6148/6148L provides a second connector designed for
external keyboard input (CN14). To locate CN14 and CN16,
please see the board layout on page 5 of chapter 1.
Chapter 2 Connecting peripherals 23
Reset switch (J1)
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 J1.
Hard disk drive LED (DLE1)
You can connect a LED to connector DLE1 to indicate when the
HDD is active. Marks on the Board layout (chapter 1, p. 5)
indicate LED polarity.
VGA display connector (CN9)
The PCA-6148 provides a VGA controller for high resolution
VGA interface. CN9 is a DB-15 connector for VGA monitor input.
Serial Ports
The PCA-6148/6148L 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 (3F8H [COM1], 2F8H
[COM2] or 2E8H) 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.

in a 128 Kbyte, 32-pin (JEDEC spec.) Flash ROM device, desig-
nated U7. A single Flash chip holds the system BIOS, VGA BIOS,
EEPROM Back-up and CMOS Data. The display can be config-
ured via software. This method minimizes the number of chips and
eases configuration. You can change the display BIOS simply by
reprogramming the Flash chip.

Driver installation
Necessary prerequisites
The instructions in this manual assume that you understand
elementary concepts of MS-DOS and the IBM Personal Comput-
er. Before you attempt to install any driver or utility you should:
know how to copy files from a floppy disk to a directory on the
hard disk, understand the MS-DOS directory structure, and know
how to format a floppy disk. If you are uncertain about any of
these concepts, please refer to the DOS or Windows user refer-
ence guides for more information before you proceed with the
installation.
Before you begin
Before you begin installing software drivers, you should make a
backup copy of the display driver diskette and store the original
in a safe place. The display driver diskette contains drivers for
several versions of certain applications. You must install the
correct version in order for the driver to work properly so make
sure you know which version of the application you have.

Flash/RAM/ROM Solid
State Disk
Appendix A Flash/RAM/ROM disk 65
APPENDIX
The PCA-6148/6148L features an internal Flash/RAM/ROM disk
drive. This drive emulates a floppy disk drive by using solid-state
memory chips (Flash, RAM or ROM) to store programs and data
instead of the magnetic particles on the mechanical drive’s disk.
The Flash/RAM/ROM disk offers much faster access times than a
floppy or hard disk and greatly increases reliability in harsh
environments.
The Flash/RAM/ROM disk works by modifying the BIOS INT-13
disk I/O routine on boot-up. The operating system must be DOS v.
5.0 or greater. The routine then translates read and write com-
mands 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/RAM/ROM disk, you will need to enable
it with the BIOS Advanced Setup Program, discussed in Chapter 3.
Memory devices
The Flash/RAM/ROM disk supports the following memory
devices, or their equivalents:
• 28F010 128 KB x 8 (+12 V) Flash Memory (AMD/INTEL)
• CXK581000P 128K x 8 SRAM (Sony)
• CXK584000P 512K x 8 SRAM (Sony)
• 27C010 128 KB x 8 EPROM
• 27C040 512 KB x 8 EPROM
• AT29C010/A 128 KB x 8 (+ 5 V) Flash Memory (ATMEL only)
• AT29C040/A 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 (AT29C010/A or AT29C040/A)
for the solid state disk, you can read or write data just like a floppy
66 PCA-6148/6148L User's Manual
disk; you need not use an external programmer. If you use +12 V
Flash memories (28F010) you will still need an "external program-
mer" to write data.
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. If you install three 128 KB chips, you will have 3 x
128 KB = 384 KB, equivalent to a 360K floppy.
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. You can press - to enter SSD
setup mode when you see the message.
Internal Solid-State Disk BIOS Rev X.XX
"SSD assign to _: Hit , if you want

Drive Selection
Floppy disks
The Flash/RAM/ROM disk will "replace" the corresponding
floppy disk. For example, if you have a single floppy disk (drive
A:) and assign the Flash/RAM/ROM disk to be the 1st drive, any
drive operations directed at drive A: will go to the Flash/RAM/
ROM disk.
Hard disks
The Flash/RAM/ROM disk will not replace corresponding hard
disks. Instead, DOS will assign the Flash/RAM/ROM disk to the
next free drive designation. For example, if you have a single hard
disk (drive C:) and assign the Flash/RAM/ROM disk to be the 3rd
drive, the Flash/RAM/ROM drive will become drive D:. If you
have two hard disks, the Flash/RAM/ROM drive will become drive
E:.

Solid State Disk (SSD) Formatting:
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.
Sometimes, it is better to assign the sectors and tracks when
formatting SSD. For the different disk size, please use different
assignment, for example:
Format drv:/u/n:9/t:40 (for 360 K disk)
Format drv:/u/n:18/t:80 (for 1.44 M disk)
where drv = solid state disk drive (A, B, or C, etc.)
After formatting, please read the message on the screen carfefully.
DOS will inform you how much disk space is available, the total
disk space, and the bad sectors, etc. If the disk size dow not match
your assignment, please check the SSD setup again.
If you need a bootable disk, you should do the system transfter by
typing:
SYS drv:
or use Format command and /S parameters.
70 PCA-6148/6148L User's Manual
Booting from the Flash/RAM/ROM disk
If you wish to have the system boot from the Flash/RAM/ROM
disk, simply set driver emulated number for the 1st FDD. Copy
your application files to the disk along with the standard system
files required to boot (command.com, io.sys, msdos.sys, 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-6148,
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!
3. When installing less than three memory devices, you must first
fill ROM-1SSD.

File copy utility
The utility program MAKEROM.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.
Appendix A Flash/RAM/ROM disk 73
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 (SSD Data
memory segment). 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 = D000 - D1FF
This excludes an 8 KB range for the card from D0000 to D1FFF
(the default addresses).
You should also make sure that the disk's memory address is not
shadowed in the BIOS. SSD program will occupy C8000 - CBFFF
when BIOS SSD setting is enabled.

Programming the
Watchdog Timer
The PCA-6148 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
Programming the watchdog timer
If you decide to program the watchdog timer, you must write data
to I/O port 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 procedure is a program for the watchdog timer:
Step 1 Out 443h data REM Start and reset the watchdog
timer.
Step 2 Your application program task #1
Step 3 Out 443h data REM Reset the timer
Step 4 Your application program task #2

POST LEDs
This appendix lists the codes generated by
the POST (Power On Self Test) routines.
It also discusses how to read the PCA-
6148's POST LED indicators.
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 nonfatal error messages is
simply to run the BIOS SETUP program, discussed in Chapter 3.
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-6148 board.
Please make a note of any POST codes before you contact
Advantech for technical support.
94 PCA-6148/6148L User's Manual
POST LEDs
Before the BIOS performs each system test, it writes a checkpoint
code to I/O address 80H. If the test fails, the code will stay in
memory. You can read the code and determine which test has
failed.
The PCA-6148’s POST LED indicators make this process ex-
tremely easy. You don’t need any special diagnostic tools, you just
read the POST code from the LEDs.
The table below shows how to read the LEDs, a series of eight
LEDs located in the top left-hand corner of the board.
