CHAPTER
Installation
This chapter tells how to connect
peripherals, switches and indicators to
the PCA-6752 Series boards. Y ou 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.
2.1 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. W ear a
grounding wrist strap for continuous protection.

2.7 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.
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 cap (often protected by a
plastic cover) that slides over the pins to connect them. To "close" a
jumper you connect the pins with the cap. T o "open" a jumper you
remove the cap. 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.

2.8 Watchdog timer configuration (JP12)
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 JP12, as
shown below:

2.9 Parallel Port Connector (CN1)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6752 Series include an on-board parallel port,
accessed through a 26-pin flat-cable connector, CN1. The card
comes with an adapter cable which lets you use a traditional
DB-25 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.
T o 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 CN1 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 CN1. Pin 1 is on the right side of CN1.
2.10 Floppy Drive Connector (CN2)
You can attach up to two floppy disk drives to the PCA-6752
Series' on-board controller. You can use any combination of
5.25" (360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 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.
22 PCA-6752 Series User's Manual
2.11 Enhanced IDE Connector (CN3)
Y ou can attach two IDE (Integrated Device Electronics) drives to the
PCA-6752 Series internal controller. The PCA-6752 Series CPU card has
an EIDE connector, CN3.
Wire number 1 on the cable is red or blue, and the other wires are gray.
Connect one end to connector CN3 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 CN3.
2.12 LCD Inverter Connector (CN4)

2.18 Audio Out/AC' 97 Connector (CN10)
AC' 97 is a audio codec specification which creates a strong
foundation for modular digital acceleration of audio and
communication functions on the SBC. AC '97 permits a more
rapid transition to PCI audio by enabling designs which
support both PCI and ISA. AC' 97 uses two separate chips, one
primarily analog, the other digital.
This "chip-level" partioning provides benefits at many levels.
The first benefit is that it helps eliminate interference between
analog and digital signals, which reduces on-chip noise, which
increases the quality of the audio output through speakers or
other devices users prefer. Another important benefit is a
realized cost savings by only having to design and tune the
analog portion of an entire line of products once. The analog
component is also less expensive to manufacturer, which is one
of the common benefits with single chip designs.

PCI Bus Ethernet
Interface (for PCA6752F/N only)
This chapter provides information on Ethernet
configuration.
• Introduction
• Installation of Ethernet driver for Windows
95/98/NT
• Further information
6.1 Introduction
The PCA-6752F/N is equipped with a high performance 32-bit
Ethernet chipset which is fully compliant with IEEE 802.3 100 Mbps
CSMA/CD standards. It is supported by major network operating
systems. It is also both 100Base-T and 10Base-T compatible. The
medium type can be configured via the RSET8139.exe program
included on the utility disk.
The Ethernet port provides a standard RJ-45 jack on board. The
network boot feature can be utilized by incorporating the boot ROM
image files for the appropriate network operating system. The boot
ROM BIOS files are combined with system BIOS, which can be
enabled/disabled in the BIOS setup.
6.2 Installation of Ethernet driver
Before installing the Ethernet driver, note the procedures below. You
must know which operating system you are using in your PCA-6752,
and then refer to the corresponding installation flow chart. Then just
follow the steps described in the flow chart. You will quickly and
successfully complete the installation, even if you are not familiar
with instructions for MS-DOS or Windows.
Note: The windows illustrations in this chapter are
examples only. You must follow the flow chart
instructions and pay attention to the instructions
which then appear on your screen.
6.2.1 Installation for MS-DOS and Windows 3.1
If you want to set up your Ethernet connection under the MS-DOS or
Windows 3.1 environment, you should first check your server system
model. For example, MS-NT, IBM-LAN server, and so on.
Then choose the correct driver to install in your panel PC.
The installation procedures for various servers can be found on
CD-ROM, the correct path being:

A
Programming
the Watchdog
Timer
The PCA-6752F 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
T o 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.
82 PCA-6752 Series 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
••
