General Information
This chapter gives background information
on the PCA-6770.
Sections include:
• Introduction
• Features
• Specifications
• Board layout and dimensions
1.1 Introduction
The PCA-6770 all-in-one industrial grade PCI-bus CPU card uses
Intel’s highly acclaimed Celeron® processor or Pentium® III
processor, together with the Intel 440BX PCI chipset.
The CPU provides 256 KB for Pentium III or 128 KB on-CPU L2
cache for Celeron, eliminating the need for external SRAM chips.
It has one PCI EIDE interface for up to two devices and a floppy
disk drive interface for up to two devices. Other features include
two RS-232 serial ports (16C550 UARTs with 16-byte FIFO or
compatible), one enhanced parallel port (supports SPP/EPP/ECP)
and one USB (Universal Serial Bus) port. The PCI enhanced IDE
controller supports Ultra DMA/33 and PIO Mode 4 operation.
This provides data transfer rates of over 33 MB/sec. System Bios
supports boot-up from an IDE CD-ROM, SCSI CD-ROM and LS-
120.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 62level Watchdog timer which resets the CPU or generates an
interrupt if a program cannot be executed normally. This enables
reliable operation in unattended environments.
The PCA-6770 offers several impressive industrial features such
as VGA AGP controller, two SODIMM slots for a total of 256 MB
RAM memory and a 10/100Base-T networking controller. In
addition, the PCA-6770 series supports a solid state disk (SSD)
using a CompactFlash™ disk that is not as vulnerable to the
hazards of an industrial computing environment. These features
make it an ideal choice for applications that require both high
performance and full functionality.

Installation
This chapter tells how to set up the
PCA-6770 hardware. It includes
instructions on setting jumpers, and
connecting peripherals, switches and
indicators. Be sure to read all the safety
precautions before you begin the
installation procedure.
2.1 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.
2.2 Jumpers
The PCA-6770 has a number of jumpers that allow you to
configure your system to suit your application. The table below
lists the function of each of the board’s jumpers.

2.6 Setting 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, connect the pins with the clip. To “open” a
jumper, remove the clip. Sometimes a jumper will have three pins,
labeled 1, 2, and 3. In this case, you would connect either pins 1
and 2 or 2 and 3.

Closed Closed 2-3
The jumper settings are schematically depicted in this manual as
follows:

Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers. Setting switches is slightly different but more simple.
Simply slide the desired switch to the on or off position. In the
example below, the 6 element switch would be. 1:off, 2:on, 3:off,
4:off, 5:off, 6:off.

2.8 Watchdog timer config. (JP2)
An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an
invaluable protective device for standalone or unmanned
applications. Setup involves two jumpers and running the control
software. (Refer to Appendix A.)
When the watchdog timer is enabled and the CPU shuts down, the
watchdog timer will automatically either reset the system or
generate an interrupt on IRQ 11, depending on the setting of
jumper JP2, as shown below:

2.13 Installation Caution
The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable. All of the
connector pin assignments are shown in Appendix C.
Warning! Always completely disconnect the power cord
from your chassis whenev er y ou are working on
it. Do not make connections while the po wer is
on. Sensitive electronic components can be
damaged by a sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.
Caution! Alw a ys ground y ourself to remo ve an y static
charge before touching the CPU card. Modern
electronic devices are v ery sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surf ace or in a static-shielded
bag when they are not in the chassis.
20 PCA-6770 User's Manual
2.14 Enhanced IDE Connector (CN1)
You can attach two IDE (Integrated Device Electronics) drives to
the PCA-6770’s internal controller. The PCA-6770 CPU card has
an EIDE connector, CN1.
Wire number 1 on the cable is red or blue, and 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 in 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.
Chapter 2 Installation 21
2.15 Parallel Port Connector (CN2)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6770 includes an on-board parallel port,
accessed through a 26-pin flat-cable connector, CN2. 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.
The parallel port is designated as LPT1, and can be disabled or
changed to LPT2 or LPT3 in the system BIOS setup.
To install the bracket, find an empty slot in your chassis. Unscrew

Note: PCA-6770 card only supports SDRAM SODIMM
modules. EDO SODIMM is not supported.
2.37.1 Installing SODIMMs
Note 1:The modules can only fit into a socket one wa y. Their
gold pins must point down into the SODIMM sock et.
Please refer to the diagram f or dimensions .
30 PCA-6770 User's Manual
The procedure for installing SODIMMs appears below. Please
follow these steps carefully.
1. Ensure that all power supplies to the system are switched Off.
2. Install the SODIMM card. Install the SODIMM so that its gold
pins point down into the SODIMM socket.
3. Slip the SODIMM into the socket at a 45 degree angle and
carefully fit the bottom of the card against the connectors.
4. Gently push the SODIMM into a perpendicular position until
the clips on the ends of the SODIMM sockets snap into place.
5. Check to ensure that the SODIMM is correctly seated and all
connector contacts touch. The SODIMM should not move around
in its socket.
Figure 2-5: Standard SODIMM Dimensions
Note 2: Only use Standard F orm SODIMM memory modules
(As shown in the dimensions above). Standardized
dimensions ensure a proper fit. Chec k with y our
Memory supplier about the SODIMM modules you will
use.
Chapter 2 Installation 31
2.38 CPU installation and upgrading
1. If you are upgrading the CPU, remove the old CPU from the
socket. If it is difficult to remove, you may find chip lubricant
(designed for pin-grid-array devices, PGAs) and a chip puller
helpful. Both are available at electronics hobby supply stores.
2. Plug the new CPU into the empty socket. Follow the
instructions that came with the CPU or math coprocessor. If
you have no instructions, do the following: Lubricate the CPU
pins with lubricant made for PGA devices. This will make the
new CPU slide in much more easily, and reduce the chance of
damaging it. Next, carefully align the CPU so that it is parallel
to the socket and the notch on the corner of the CPU
corresponds with the notch on the inside of the socket. Gently
slide the CPU in. There will probably be a gap between the
CPU and the connector when it is fully seated - do not push too
hard!

A
Programming
the Watchdog
Timer
The PCA-6770 is equipped with a
watchdog timer that resets the
CPU or generates an interrupt if
processing comes to a standstill for
any reason. This feature ensures
system reliability in industrial
standalone or unmanned
environments.
A.1 Programming the Watchdog Timer
To program the watchdog timer, you must write a program which
writes I/O port address 443 (hex). The output data is a value of time
interval. The value range is from 01 (hex) to 3E (hex), and the related
time interval is 1 sec. to 62 sec.
Data Time Interval
01 1 sec.
02 2 sec.
03 3 sec.
04 4 sec.
••
••
••
3E 62 sec.
66 PCA-6770 User's Manual
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 443 (hex).
The following example shows how you might program the watchdog
timer in BASIC:
10 REM Watchdog timer example program
20 OUT &H443, data REM Start and restart the watchdog
30 GOSUB 1000 REM Your application task #1,
40 OUT &H443, data REM Reset the timer
50 GOSUB 2000 REM Your application task #2,
60 OUT &H443, data REM Reset the timer
70 X=INP (&H443) REM, Disable the watchdog timer
80 END
1000 REM Subroutine #1, your application task

Installing PC/104
Modules
This appendix gives instructions for
installing PC/104 modules.
B.1 Installing PC/104 modules
The PCA-6770 PC/104 connectors give you the flexibility to attach
PC/104 modules.
Installing these modules on the PCA-6770 is quick and simple. The
following steps show how to mount the PC/104 modules:
1. Remove the PCA-6770 from your system paying particular
attention to the safety instructions already mentioned above.
2. Make any jumper or link changes required to the CPU card now.
Once the PC/104 module is mounted you may have difficulty in
accessing these.
3. Normal PC/104 modules have male connectors and mount directly
onto the main card. (Refer to the diagram on the following page.)
4. Mount the PC/104 module onto the CPU card by pressing the
module firmly but carefully onto the mounting connectors.
5. Secure the PC/104 module onto the CPU card using the four
mounting spacers and screws.
