General Information
This chapter gives background information on the PCA-6753F.
Sections include:
• Board specifications
• Board layout and dimensions
1.1 Introduction
The PCA-6753F is the ultimate cost-effective solution for limited
space applications. It offers all the functions of an AT-compatible
industrial computer on a single board. The PCA-6753F comes
with an embedded high-performance GXm-200 processor onboard. For maximum performance, the PCA-6753F also supports
an SDRAM DIMM socket that can accept up to 128 MB memory.
On-board features include an Ethernet interface, a socket for
DOC® 2000, Enhanced IDE interface with up to 33 MB/s Ultra
DMA transfer protocol, one parallel port, two serial ports (RS-232
and RS-232/422/485) with DB-9 connector as COM1, and a miniDIN 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-6753F 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-6753F 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.

Closed 2-3Open Closed
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.

Chapter 2 Connecting Peripherals 17
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-6753F internal controller. The PCA-6753F 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.
18 PCA-6753F User's Manual
2.7 FDD connector (CN2)
You can attach up to two floppy disk drives to the PCA-6753F'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 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.
2.8 Parallel port connector (CN3)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6753F includes an on-board 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.
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 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 Peripherals 19
2.9 Flat panel display connector (CN5)
CN5 consists of a 44-pin, dual-in-line header.
The power supply (+12 V) for CN5 is dependant on the supply
connected to the board. Therefore make sure that CN9 is connected to
a +12 V power supply.
The PCA-6753F provides a bias control signal on CN5 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
PCA-6753F board's power is applied, the control signal is low until
just after the relevant flat panel signals are present.
2.10 VGA display connector (CN6)
The PCA-6753F provides a VGA controller for a high resolution
