to the cost of replacement materials, service time and freight.
Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered (e.g.
type of PC, CPU speed, Advantech products used, other
hardware and software used etc.). Note anything abnormal and
list any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your
manual, product and any other information readily available.
3. If your product is diagnosed as defective, obtain an RMA
(return material authorization) number from your dealer. This
allows us to process your return more quickly.
4. Carefully pack the defective product, a completely filled-out
Repair and Replacement Order Card and a photocopy of a
dated proof of purchase (such as your sales receipt) in a
shippable container. A product returned without dated proof of
purchase is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package
and ship it prepaid to your dealer.

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 on-
board.
If program execution is halted by a program bug or EMI, the board's 63-
level 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.

Jumpers and connectors
Connectors on the board link it to external devices such as hard disk
drives, a keyboard, or floppy drives. In addition, the board has a
number of jumpers which you use to configure it for your application.
The table below lists the function of each of the board jumpers and
connectors. Later sections in this chapter give instructions on setting
jumpers and detailed information on each jumper setting. Chapter 2
gives instructions for connecting external devices to your card.

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.

8PCA-6144V 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 operat-
ing 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.
You may find pair of needle-nose pliers useful for setting the jumpers.
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.
