General Information
This chapter gives background information on the PCA-6740.
Sections include:
• Board specifications
• Board layout and dimensions
1.1
Introduction
The PCA-6740 is the ultimate cost-effective solution for limitedspace applications. It offers all the functions of an AT-compatible
industrial computer on a single board. The PCA-6740 comes with
an embedded high-performance STPC Elite 133 processor and
32MB SDRAM on board. For maximum performance, the PCA-6740
also supports one optional SODIMM socket that can accept up to
64 MB memory.
On-board features include an Ethernet interface, a socket for DOC®
2000, Enhanced IDE interface, one parallel port, two serial ports
(RS-232 and RS-232/422/485) with DB-9 connector as COM1, and a
mini-DIN PS/2 keyboard/mouse interface. An SVGA/LCD display
controller (LCD, and CRT displays) allows LCD screen resolutions
up to 1024 x 768 @ 64K colors and CRT resolutions up to 1280 x
1024 @ 256 colors.
The PCA-6740 complies with the "Green Function" standard and
supports three types of power saving features: Normal, Doze and
Sleep modes.
The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This
minimizes the number of chips and eases configuration. You can
change the display BIOS simply by programming the Flash chip.
If you need any additional functions, the PCA-6740 has a PC/104
connector for future upgrades.

2.4 Setting jumpers
2.4.1 Introduction
You may configure your card to match the needs of your application
by setting jumpers. A jumper is the simplest kind of electrical 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 would connect either pins 1 and 2 or 2 and 3.

A pair of needle-nose pliers may be helpful when working with
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.
Generally, you simply need a standard cable to make most connections.

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 A.
Warning! Always completely disconnect the power cord from
your chassis whenever you are working on it. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by a
sudden rush of power. Only experienced electronics
personnel should open the PC chassis.
Caution!
Always ground yourself to remove any static charge
before touching the CPU card. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative
surface or in a static-shielded bag when they are not
in the chassis.
2.6 Enhanced IDE connector (CN1)
You can attach two IDE (Integrated Device Electronics) drives to the
PCA-6740 internal controller. The PCA-6740 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. See
Figure 2-1, where pin 1 is indicated with a triangle and a solid square.
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
should be labeled on the drive circuit board. Check the documentation
that came with the drive for more information. If you are using a
second drive, connect it to the remaining connector on the same cable.
16
PCA-6740 User's Manual
2.7 FDD connector (CN2)
You can attach up to two floppy disk drives to the PCA-6740's
onboard 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 34pin flat-cable connector (usually used for 3.5" drives) and a printedcircuit-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.
2.8 Parallel port connector (CN3)
The parallel port is designated as LPT1, and is normally used to
connect the CPU card to a printer. The PCA-6740 includes an onboard parallel port, accessed through a 26-pin flat-cable connector,
CN3. 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.
To 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 CN3 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 CN3. Pin 1 is on the
right side of CN3.
Chapter 2 Connecting
17
2.9 Flat panel display connector (CN4)
CN4 consists of a 44-pin, dual-in-line header.
The power supply (+12 V) for CN4 is dependant on the supply
connected to the board. Therefore make sure that CN17 is connected
to a +12 V power supply.
The PCA-6740 provides a bias control signal on CN4 which can be
used to control the LCD bias voltage. It is recommended that the LCD
bias voltage not be applied to the panel until the logic supply voltage
(+5 V or +3.3 V) and panel video signals are stable. Under normal
operation the control signal (ENAVEE) is active high. When the PCA6740 board's power is applied, the control signal is low until just after
the relevant flat panel signals are present.
2.10 ATX power button (CN6, pins 17,19)
The PCA-6740 provides an ATX power input connector. When
connected with the ATX power switch, the ATX power switch connector (CN6) enables power On/Off from the chassis.
2.11 Reset switch (CN6, pins 9,11)
If you install a reset switch, it should be a single pole switch rated at
10 mA, 5 V. Momentarily pressing the switch will activate a reset.
For reset switch pin assignments, please see Appendix A.
2.12 IR connector (CN6 pins 12,14,16,18,20)
This connector supports the optional wireless infrared transmitting and
receiving module. This module mounts on the system case. You must
configure the setting through BIOS setup.
18
PCA-6740 User's Manual
2.13 ATX Feature Connector (CN7)
When the PCA-6740 is used as a standalone card, the main power
connector (CN7) is used. If the PCA-6740 is used with a passive
backplane, the main power connector (CN7) should not be connected.
This is because the card will be powered from the backplane.

2.17 Serial ports
(CN15: COM1; CN14: COM2/RS-232;
CN13: COM2/RS-422/485)
The PCA-6740 offers two serial ports: COM1 in RS-232 and COM2
(CN14: RS-232, CN13:RS-422/485). These ports let you connect to
serial devices (a mouse, printers, etc.) or a communication network.
You can select the address for each port (for example, 3F8H [COM1],
2F8H [COM2]) or disable each port. Use the BIOS Advanced Setup
program, which is covered in Chapter 4.
The card mounting bracket holds the serial port connector for the one
port. The parallel port and serial port adapter kit (supplied with the
card) holds the connector for the other port. This lets you connect and
disconnect cables after you install the card. The DB-9 connector on the
bottom of the bracket is the first RS-232 port, COM1. The DB-9
connector on the adapter kit is the second serial port, COM2.

Award BIOS Setup
This chapter describes how to set BIOS
configuration data.
3.1
System test and initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors. Non-fatal error messages
usually appear on the screen along with the following instructions:
press <F1> to RESUME
Write down the message and press the F1 key to continue the
bootup sequence.
3.1.1 System configuration verification
These routines check the current system configuration against the
values stored in the board’s CMOS memory. If they do not match,
the program outputs an error message. You will then need to run
the BIOS setup program to set the configuration information in
memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The PCA-6740 CMOS memory has an integral lithium battery
backup. The battery backup should last ten years in normal service,
but when it finally runs down, you will need to replace the complete
unit.

Installing PC/104
Modules
This appendix gives instructions for
installing PC/104 modules.
D.1 Installing PC/104 modules
The PCA-6740F PC/104 connectors give you the flexibility to attach
PC/104 modules.
Installing these modules on the PCA-6740F is quick and simple. The
following steps show how to mount the PC/104 modules:
1. Remove the PCA-6740F 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.

Programming the
Watchdog Timer
The PCA-6740 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.
E.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.

PCA-6740 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:
