Introduction
The PCA-6155 packs all the functions of an industrial computer,
including IDE, FDD controller, RS-232 ports and a parallel port onto a
half-size card. This PICMG-compliant, all-in-one board supports Intel
Pentium and Cyrix 6x86 processors and can be used with PCIMG-
compliant PCI/ISA passive backplanes.
The PCA-6155's two PCI-bus enhanced IDE ports support PIO mode
4 and DMA bus master IDE transfer, enabling data transfer rates in
excess of 16 MB/second. Up to four 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 RS-232 ports with 16C550 UARTs
(one of which can also function as an infrared port) and one bidirec-
tional SPP/EPP/ECP parallel port. It provides COAST (Cache On A
STick) pipeline burst synchronous cache RAM. The PCA-6155 can
pack up to 128 MB of memory, using normal DRAM or EDO RAM.
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 watchdog timer interval is set by software and can be
changed during runtime, eliminating jumper switch setting.

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.

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.

Module) sockets that provide anywhere from 2 MB to 128 MB of
DRAM. Each socket accepts from 1 to 32 MB of DRAM. For more
detailed information please refer to the memory configuration tables
on page 12 of this manual.
