CHAPTER
Hardware
Configuration
This chapter gives background information on the PCA-6144V. It then shows you
how to configure the card to match your
application and prepare it for installation
into your PC.
Sections include:
• Card specifications
• Board layout
• Safety precautions
• Jumper settings
• Installing DRAM (SIMMs)
Chapter 1 Hardware Configuration 1
Introduction
The PCA-6144V is an all-in-one single board 486 computer that includes
an on-board SVGA controller. It packs all the functions of an industrial
computer, including display capabilities, on a single half-size card. The
PCA-6144V is fully PC/AT compatible, so your software will run without
modifications.
The on-board VL-bus SVGA controller uses the Trident TGUI 9440
chipset with 1 MB video memory. This chipset, used with the local bus,
enables 32-bit graphic throughput at up to 33 MHz. The TGUI 9440 also
offers Windows graphics acceleration. These features are excellent for
display-intensive applications.
Another feature of the PCA-6144V is the inclusion of a fast VL bus
enhanced IDE controller. This controller supports mode 4, which enables
data transfer rates in excess of 16 MB/second. Up to two IDE devices can
be connected, including large hard disks (up to 8 GB), CD-ROM drives,
Tape backup drives or other enhanced IDE devices.
On-board features also include two high-speed serial ports with 16C550
UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive
controller. In addition to the 486's 8 KB of on-chip cache memory, the
PCA-6144V includes an extra 128 KB of second level cache memory onboard.
If program execution is halted by a program bug or EMI, the board's 63level watchdog timer can automatically reset the CPU or generate an
interrupt. This ensures reliability in unmanned or standalone systems. The
timer interval of the watchdog timer is set by software, eliminating jumper
switch setting.
The PCA-6144V provides two 72-pin SIMM (Single In-line Memory
Module) sockets for its on-board system DRAM. These sockets give you
the flexibility to configure your system from 1 MB to 64 MB of DRAM
using the most economical combination of SIMMs.

Safety precautions
Follow these simple precautions to protect yourself from harm and
your PC from damage.
1. T o 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.
Chapter 1 Hardware Configuration 7
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. T o “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-6144V. The card provides two 72-pin SIMM (Single In-Line
Memory Module) sockets that accept from 1 to 32 MB DRAM each.
The sockets (numbered from 1 to 2) are arranged into two banks. The
following table shows the bank assignments for the SIMM sockets:
Bank SIMM socket(s) Size
1 SIMM1 72-pin
2 SIMM2 72-pin
The PCA-6144V's memory sockets accept any combination of SIMMs
(up to 64 MB), inserted in any order.

CHAPTER
Connecting
peripherals
This chapter tells how to connect peripherals, switches and indicators to the PCA6144V 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.
Chapter 2 Connecting peripherals 15
The following table lists the connectors on the PCA-6144V. See
Chapter 1 for help locating the connectors.

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.
16 PCA-6144V User's Manual
Enhanced IDE connectors (CN1)
You can attach two IDE (Integrated Device Electronics) drives to
the PCA-6144V's internal controller. The PCA-6144V CPU card
has an EIDE connector, CN1.
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 (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 CN1.
Floppy drive connector (CN4)
You can attach up to two floppy disk drives to the PCA-6144V'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.
Chapter 2 Connecting peripherals 17
Parallel port (CN7)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6144V includes an on-board parallel port,
accessed through a 26-pin flat-cable connector, CN7. The card
comes with an adapter cable which lets you use a traditional DB25 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 CN7 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 CN7.
Pin 1 is on the right side of CN7.
Keyboard & PS/2 mouse connectors
(CN5)
The PCA-6144V board provides a keyboard connector. A 6-pin
mini-DIN connector (CN5) 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.
18 PCA-6144V User's Manual
Reset switch (J29)
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 J29.
Hard disk drive LED (D2)
You can connect a LED to connector D2 to indicate when the HDD
is active. Marks on the circuit board indicate LED polarity.
VGA display connector (CN8)
The PCA-6144V provides a VGA controller for high resolution
VGA interface. CN8 is a DB-15 connector for VGA monitor input.
Serial Ports
The PCA-6144V offers two serial ports: COM1 in RS-232, COM2
in RS-232/485. 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, 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.

Chapter 4 SVGA Setup 37
SVGA driver installation
Installing from Windows
The graphic installation program (TINSTALL) supports a simple
6 step installation procedure for the display driver setup program,
the power management program and the UNinstall program.
To use TINSTALL, follow the 6 steps below:
1. Ensure that MS Windows 3.1 is up and running properly,
using the standard VGA driver.
2. Select the MAIN group in Program Manager.
3. Select RUN from the FILE menu on the menu bar.
5. Type in A:TINSTALL (if the display driver disk is in the B
drive, type in B:TINSTALL instead), as shown below, and
then press <ENTER>.
6. A menu will appear, presenting a choice of Express or
Custom Installation.
38 PCA-6144V User's Manual
Express Installation
Express Installation automatically copies the display drivers into
the TRIDENT.AGI directory and the Utility files into the
TRIDENT.UTL directory. Once all files are copied, a program
group called DISPLAY DRIVER AND UTILITIES will be
created.
Custom Installation
Custom Installation allows control over where files are stored and
in what program group the icons are placed. The first dialog box
that appears shows the default directory to which the display
drivers will be copied.
To change the directory name:
1. Delete the default name.
2. Enter the desired directory name.
3. Once the desired directory name is selected, continue the
installation procedure by selecting Continue, or by pressing
<ENTER>.
The next dialog box displays a summary of where files are stored.
4. Select Continue to copy the drivers and utilities files.
When all files are copied, the program will present a choice of
program groups where the icons will be created. Create a new
group to place the utility icons or select from pre-existing groups
(e.g. Main, Applications, Accessories, etc.).
Tinstall icons
The Tinstall program creates three icons:
a. Screen Control (Used to configure display drivers)
b. DPMS (Used for power management configurations)
c. UNinstall (Used to delete the installed TRIDENT drivers)
NOTE: Different “display driver set” versions cannot be
installed to the same directory name.
“Display driver sets” of the same version number ( e.g. UA6.0 )
will replace the existing one.
Chapter 4 SVGA Setup 39
Screen Control
The Screen Control panel contains controls for setting screen
resolution, color depth, font size, refresh rates. Not all
combinations of screen resolution, color depth, font size and
refresh rate are attainable.
Color depths of 16, 256, 64K, or 16.7M colors can be selected
by clicking next to the desired option. Color depth determines
the number of colors that may be simultaneously displayed on
the screen. The selected color depth determines the possible
resolutions.
Screen resolutions of 640x480, 800x600, 1024x768,
1280x1024, or 1600x1200 can be selected by clicking next to
the available options. The virtual screen size is automatically
adjusted to be at least as large as the selected screen resolution.
Available refresh rates are dependent on the selected color
depth and resolution. The “Back to Default” option is used to
reset the refresh rate to the factory default value.
To open Screen Control, double click on its icon. The following figure shows the Screen Control interface:
40 PCA-6144V User's Manual
Configuring the Display Driver
1. Select the color depth first. If the current driver does not
support the selected color depth, then Windows will have to
be restarted.
2. Select the resolution.
3. Select the font size (if available as an option).
4. Select the refresh rate.
5. Click on OK. If the current driver does not support the
selected configuration, Windows will have to be restarted.
Note: Hot Key Control should be enabled before
going into advanced setup. There is no virtual
screen support for 16 colors. 1280x1024 is only
available for 16 colors.
Chapter 4 SVGA Setup 41
Advanced features (Virtual Screen Control)
Virtual Screen Control
Standard display resolutions are 640x480, 800x600, 1024x768,
1280x1024. The amount of display memory used depends on the
selected resolution and color depth. A substantial amount of
display memory is left unused for lower resolutions. The Virtual
Screen features take advantage of this unused memory by “expanding” the display area into the off-screen area.
Virtual Screen Control allows the user to make effective use of a
display screen larger than the standard 640x480, 800x600 or
1024x768, and the standard resolution is the center of the screen.
The user can “pan” around the larger Virtual Screen area by the
use of a standard mouse or a set of “HOT KEYS.” For example, it
is possible to select a resolution of 640x480 and set the Virtual
Screen size to 800 x 600. Thus, the 640 x 480 screen sits at the
center of a 800 x 600 matrix, and the user can “pan” through the
entire 800x600 matrix in a 640x480 window, as shown below.
Panning allows trav ersing a larger screen through a smaller window .

presents the following features:
1. Hot Key selection, which allows you to set up predefined
key strokes for specific virtual screen related actions.
2. Turn On virtual screen, which allows the use of the
predefined virtual screen sizes. The predefined virtual screen
sizes are selected by clicking next to available options. The
sizes of the available predefined virtual screens are dependent on the selected color depth and resolution.
3. Customize virtual screen area, which opens up a new screen
titled Virtual Screen Advanced Settings:
Chapter 4 SVGA Setup 43
Virtual Screen Advanced Settings
• Freeze Screen: Disables the panning feature, giving the
illusion of a frozen screen but keeping other virtual screen
functions available. Hot key functions are available for this
feature.
• Linear Frame Buffer Address: The Linear Addressing
driver automatically detects the system’s memory size and sets
the frame buffer to an unused area above the system memory.
The Linear Frame Buffer Address setting is useful in avoiding
conflicts with Windows applications, which use the same
linear frame buffer address as the Display Driver. Addresses
between 18 and 63 MB can be selected. If there is no conflict,
the default setting is highly recommended.
• Border Space: The Border Space option is used to set up a
border (thickness measured in pixels) within the displayable
area. The border is used as a marker for panning the screen,
i.e. when the cursor hits against this border, screen panning
occurs as shown below:
• Pan Set Hot Key: Hot keys can be set up to pan the virtual
screen left, right, up and down. The feature has to be enabled
by clicking on the Enable box before hot keys can be selected.
Once all selections are made, click on OK or press <ALT> + O
to exit the advanced setup.

Appendix
A
Programming the
Watchdog Timer
The PCA-6144V 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 A Programming the Watchdog Timer 59
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 IRQ11. 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
1070 RETURN
2000 REM Subroutine #2, takes 2 seconds to complete
2090 RETURN
