2.5 Setting Jumpers
You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir-
cuit. 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.

2.8 Watchdog timer configuration
An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu-
able protective device for standalone or unmanned applications. Setup
involves one jumper and running the control software (refer to Appendix
A).
2.8.1 Watchdog timer output option (J2)
When the watchdog timer activates (CPU processing has come to a halt),
it can reset the system or generate an interrupt on IRQ11. This can be set
via setting J2 as shown below:

2.9 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den-
sity.
1.
2.
3.
Make sure that the two handles of the DIMM socket are in the
“open” position. i.e. The handles remain leaning outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
Press the DIMM module right down into the socket, until you hear
a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.
To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.

2.11 Printer port connector (CN4)
Normally, the parallel port is used to connect the card to a printer. The
PCA-6774 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN4 and a 26-pin flat-cable connector. You will need an adapter cable
if you use a traditional DB-25 connector. The adapter cable has a 26-pin
connector on one end, and a DB-25 connector on the other.
The parallel port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
2.12 CompactFlash Socket
The PCA-6774 provides a 50-pin socket for CompactFlash card type I/II.
2.12.1 CompactFlash (CN5)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
2.13 Floppy drive connector (CN3)
You can attach up to two floppy drives to the PCA-6774’s on-board con-
troller. You can use any combination of 5.25” (360 KB and 1.2 MB) and/
or 3.5” (720 KB, 1.44 MB, and 2.88 MB) drives.
A 20-pin daisy-chain drive connector cable is required for a dual-drive
system. On one end of the cable is a 20-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).
2.13.1 Connecting the floppy drive
1.
Plug the 20-pin flat-cable connector into CN3. Make sure that the
red wire corresponds to pin one on the connector.
2.
Attach the appropriate connector on the other end of the cable to
the floppy drive(s). You can use only one connector in the set. The

set on the end (after the twist in the cable) connects to the A: drive.
The set in the middle connects to the B: drive.
3.
If you are connecting a 5.25” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connec-
tor.
If you are connecting a 3.5” floppy drive, you may have trouble determin-
ing which pin is number one. Look for a number printed on the circuit
board indicating pin number one. In addition, the connector on the floppy
drive may have a slot. When the slot is up, pin number one should be on
the right. Check the documentation that came with the drive for more
information.
If you desire, connect the B: drive to the connectors in the middle of the
cable as described above.
In case you need to make your own cable, you can find the pin assign-
ments for the board’s connector in Appendix B.
2.14 IDE connector (CN1,CN2)
The PCA-6774 provides an IDE channel to which you can attach up to
two Enhanced Integrated Device Electronics hard disk drives or CDROM
to the PCA-6774’s internal controller. The PCA-6774's IDE controller
uses a PCI interface. This advanced IDE controller supports faster data
transfer, PIO Mode 3 or Mode 4, UDMA 33/66/100 mode.
2.14.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one of two
cables (not included in this package), depending on the drive size. 1.8"
and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connector.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1.
Connect one end of the cable to CN1, CN2. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
2.
Plug the other end of the cable into the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the con-
nector.)
If desired, connect a second drive as described above.
PCA-6774 User Manual 18

Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install only one
drive, set it as the master.
2.15 VGA/LCD interface connections
The PCA-6774’s display interface can drive conventional CRT displays
and is capable of driving a wide range of flat panel displays as well,
including passive LCD and active LCD displays. The board has two dis-
play connectors: one for standard CRT VGA monitors, and one for flat
panel displays.
2.15.1 CRT display connector (CN7)
CN7 is a standard 15-pin D-SUB connector commonly used for VGA.
Pin assignments for CRT display connector CN7 are detailed in Appendix
B.
2.15.2 Flat panel display connector (CN22)
CN22 consists of a 40-pin connector which can support an 18-bit LCD
panel. It is Hirose’s product no. DF13A-40DP-1.25 V.
The PCA-6774 provides a bias control signal on CN22 that can be used to
control the LCD bias voltage. It is recommended that the LCD bias volt-
age 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-6774’s power is
applied, the control signal is low until just after the relevant flat panel sig-
nals are present. CN22 can connect up to 18-bit TFT LCD.
2.15.3 Extension flat panel connector (CN23)
CN23 consists of a 20-pin connector which is Hirose's product no. DF13-
20DP-1.25V. The PCA-6774 supports a 36-bit LCD panel which must be
connected to both the CN22 (40-pin) and CN23 (20-pin). The pin assign-
ments for both CN22 and CN23 can be found in Appendix B.
2.15.4 LVDS LCD panel connector (CN25)

Chapter 3 Software Configuration
3.1 Introduction
The system BIOS and custom drivers are located in a 256 KB, 32-pin
(JEDEC spec.) Flash ROM device, designated U10. A single Flash chip
holds the system BIOS, VGA BIOS, and network Boot ROM image. The
display can be configured via software. This method minimizes the num-
ber of chips and eases configuration. You can change the display BIOS
simply by reprogramming the Flash chip.
3.2 VGA display firmware configuration
The board’s on-board VGA interface supports a wide range of popular
LCD, EL, gas plasma flat panel displays and traditional analog CRT mon-
itors. The optimized shared memory architecture supports an 8/16/32 MB
frame buffer using system memory to provide resolutions of 1280 x 1024
@ 16 bpp, the interface can drive CRT displays with resolutions up to
1024 x 768 @ 16 bpp and 800 x 600 @ 16 bpp.
The VGA interface is configured completely via the software utility, so
you do not have to set any jumpers. Configure the VGA display as fol-
lows:
1.
Apply power to the board with a color TFT display attached. This
is the default setting for this board. Ensure that the AWD-
FLASH.EXE and *.BIN files are located in the working drive.
NOTE:
Ensure that you do not run AWDFLASH.EXE
while your system is operating in EMM386
mode.

At the prompt, enter the new BIN file which supports your display.
When you are sure that you have entered the file name correctly
press <Enter>.
The screen will ask if you want to save BIOS? If you change your
mind or have made a mistake, press N to abort and end the setup
procedure. Press Y if you wish to save the existing configuration
before changing it. Then type the name under which you want to
save the current configuration.
5.
The prompt will then ask “Are you sure”, Press Y if you want the
new file to be written into the BIOS. Press N to exit the program.
The new VGA configuration will then write to the ROM BIOS chip. This
configuration will remain the same until you run the AWDFLASH.EXE
program and change the settings.

4.1 System test and initialization
These routines test and initialize board hardware. If the routines encoun-
ter 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 boot up
sequence.
4.1.1 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 pro-
gram to set the configuration information in memory.
There are three situations in which you will need to change the CMOS
settings:
1.
2.
3.
You are starting your system for the first time
You have changed the hardware attached to your system
The CMOS memory has lost power and the configuration informa-
tion has been erased.

The board 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.

Appendix A Programming the Watchdog
Timer
A.1 Supported Input Timing Modes
In order 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 inter-
val. The value range is from 01 (hex) to 3E (hex), and the related time
interval is 1 sec. to 62 sec.

.

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).
