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 control-
ler 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.

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
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.

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. 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.

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.
