Hardware Configuration
This chapter gives background
information on the PCA-6175. It then
shows you how to configure the card to
match your application and prepare it for
installation into your PC.
Sections include:
• Card specifications
• Board layout
• Safety precautions
• Jumper settings
1.1 Introduction
The PCA-6175 industrial grade CPU card uses Intel's highly
acclaimed Pentium® II processor and Intel 440LX PCI chipset. The
card works with standard ISA or PCI/ISA-bus passive backplanes.
The CPU provides 512 KB on-chip L2 cache, eliminating the need for
external SRAM chips. It has two PCI EIDE interfaces (for up to four
devices), and an FDD 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 EPP/ECP), and
support for two USB (Universal Serial Bus) ports. The PCI BUS
Master IDE controller supports Ultra DMA/33 operation. This
provides data transfer rates of over 33 MB/sec, and allows drive
capacities up to 8.4 GB. System BIOS supports boot-up from an IDE
CD-ROM.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 63-level
watchdog timer, which resets the CPU or generates an interrupt if a
program cannot be executed normally. This enables reliable operation
in unattended environments.

1.8 Safety Precautions
Warning! Always completely disconnect the power cord from
your chassis whenever you work with the hardware.
Do not make connections while the power is on.
Sensitive electronic components can be damaged
by sudden power surges. 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.
As a safety precaution, use a grounding wrist strap
at all times. Place all electronic components in a
static-dissipative surface or static-shielded bag when
they are not in the chassis.

1.9 Jumper Settings
This section provides instructions on how to configure your card by
setting jumpers. It also includes the card's default settings and your
options for each jumper.
1.9.1 How to set 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 you connect the pins with the clip. To “open” a jumper you
remove the clip. Sometimes a jumper consists of a set of three pins,
labeled 1, 2 and 3. In this case you connect either pins 1 and 2, or 2 and 3.
A pair of needle-nose pliers may be useful when setting jumpers.
1.9.2 CPU core frequency (J5)
You must configure your PCA-6175 CPU card to the frequency of your
Intel Pentium® II processor by setting jumper J5. The PCA-6175 is
equpped to use Pentium processors with speeds of 233, 266, 300 and
333 MHz. Configure your PCA-6175 as follows:

1.9.3 CMOS clear (J6)
The PCA-6175 CPU card contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should
be set with pins 1-2 closed. If you want to reset the CMOS data, set J6
to 2-3 closed for just a few seconds, and then move the jumper back to
1-2 closed. This procedure will reset the CMOS to its default setting.

1.9.4 Watchdog timer output (J8)
The PCA-6175 contains a watchdog timer that will reset the CPU or
send a signal to IRQ11 in the event the CPU stops processing. This
feature means the PCA-6175 will recover from a software failure or an
EMI problem. The J8 jumper settings control the outcome of what the
computer will do in the event the watchdog timer is tripped.

1.10 System Memory
The top-left edge of the PCA-6175 contains three sockets for 168-pin
dual inline memory modules (DIMMs). All three sockets use 3.3 V
unbuffered synchronous DRAMs (SDRAM). DIMMs are available in
capacities of 16, 32, 64 or 128 MB. The sockets can be filled in any
combination with DIMMs of any size, giving your PCA-6175 single
board computer between 16 and 384 MB of memory. Use the following
table to calculate the total DRAM memory within your computer:
Table 1-8: DIMM module allocation table
Socket number

1.10.1 Sample calculation: DIMM memory capacity
Suppose you install a 128 MB DIMM into your PCA-6175's socket 1,
a 32 MB DIMM into socket 2, and you leave socket 3 empty. Your
total system memory is calculated as follows, and is 160 MB:

PCA-6175 User's Manual
1.10.2 Supplementary information about DIMMs
Your PCA-6175 can accept four kinds of memory chips: EDO (with or
without parity), and SDRAM (with or without parity). Also:
• SDRAM chips are usually thinner and have higher pin density than
EDO chips.
• The BIOS displays EDO and SDRAM memory on the boot-up
screen.
• Chips with 9 chips/side support parity; chips with 8 chips/side do not
support parity.
• Single-sided modules are typically 16 or 64 MB; double-sided
modules are usually 8, 32 or 128 MB.
Note:
The PCA-6175 accepts EDOs both with and without
parity, but this is not recommended.
Chapter 1 Hardware Configuration
17
1.11 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM
socket are in the "open" position. i.e. The handles remain outward.
Slowly slide the DIMM module along the plastic guides on both ends
of the socket. Then 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 DIMM socket. (See Figure 1-3.) To take away the memory
module, just push both handles outward, and the memory module will
be ejected by the mechanism in the socket.

1.12 Cache Memory
Since the second level cache has been embedded into the Pentium® II
CPU, you do not have to take care of either SRAM chips or SRAM
modules. The built-in second level cache in the Pentium II yields much
higher performance than the external cache memories. The cache size
in the Pentium II CPU is either 256 KB or 512 KB. Normally, for
workstation and server application, the 256 KB version is enough.
However, if your system is for heavy duty applications, the 512 KB
version will help a lot. Specifically for our Pentium II based SBC, the
Pentium II has another version that provides much better data security
if combined with the DRAM ECC. Check with your vendor for various
Pentium II models.
Chapter 1 Hardware Configuration
19
1.13 Mounting the CPU and Cooling Modules
The Pentium® II is a module-type CPU which runs at high speeds, for
exampe 233 ~ 333 MHz, so the cooling mechanism becomes critical
for system reliability. There are two types of cooling methods: one
with a cooling fan attached to the heat sink of the Pentium II module,
the other with a huge heat sink without any cooling fan attached.
Both cooling methods for the Pentium II require a "retention module"
to firmly fix the PentiumII CPU to slot 1. The following Figures 1-4
through 1-6 illustrate the steps involved in mounting the retention
module and installing the CPU and cooling modules.

Connecting Peripherals
This chapter tells how to connect
peripherals, switches and indicators to the
PCA-6175 board. You 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 Primary (CN6) and Secondary (CN7) IDE
Connectors
You can attach up to four IDE (Integrated Device Electronics) drives
to the PCA-6175’s internal controller. The primary (CN6) and
secondary (CN7) connectors can each accommodate two drives.
Wire number 1 on the cable is red or blue and the other wires are
gray. Connect one end to connector CN6 or CN7 on the CPU card.
Make sure that the red/blue wire corresponds to pin 1 on the connec-
tor (in the upper right hand corner). See Chapter 1 for help finding the
connector.
Unlike floppy drives, IDE hard drives can connect in either position
on the cable. If you install two drives to a single connector, 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 per
connector, you should set each drive as the master. See the documen-
tation 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 hard drive to the remaining connector (CN7 or
CN6), in the same way as described above.
2.2 Floppy Drive Connector (CN13)
You can attach up to two floppy disk drives to the PCA-6175's
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 drive. The set in the middle
connects to the B: floppy drive.

PCA-6175 User's Manual
2.3 Parallel Port Connector (CN8)
The parallel port is normally used to connect the CPU card to a
printer. The PCA-6175 includes an on-board parallel port, accessed
through a 26-pin flat-cable connector, CN8. 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 connec-
tor.
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 CN8 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 CN8. Pin 1 is on the
upper right side of CN8.
2.4 Keyboard & PS/2 Mouse Connector (CN12)
The PCA-6175 board provides a keyboard connector. A 6-pin
mini-DIN connector (CN12) on the card mounting bracket supports
single-board computer applications. The card comes with an adapter
to convert from the 6-pin mini-DIN connector to a standard DIN
connector and to a PS/2 mouse connector.
Chapter 2 Connecting Peripherals
25
2.5 Serial Ports (CN9: COM1; CN10: COM2)
The PCA-6175 offers two serial ports, CN1 as COM1 and CN2 as
COM2. These ports can connect to serial devices (such as a mouse,
printers, and so on) or to a communication network.

The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do
this in the system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.

2.7 ATX Power Control Connectors
(J7 and J1)
2.7.1 ATX feature connector (J7) and soft power
switch connector (J1)
The PCA-6175 can support an advanced soft power switch function if
an ATX power supply is used. To enable the soft power switch
function:
1. Take the specially designed ATX-to-PS/2 power cable out of the
PCA-6175's accessory bag.
2. Connect the 3-pin plug of the cable to J7 (ATX feature connector).
3. Connect the power on/off button to J1. (A momentary type of
button should be used.)
Important: Be sure that the ATX power supply can take at least
a 10 mA load on the 5 V standby lead (5VSB). If not,
you may have difficulty powering on your system.

2.8 USB Connector (CN11)
The PCA-6175 CPU card provides two USB (Universal Serial Bus)
interfaces, which give complete plug and play, hot attach/detach for
up to 127 external devices.The USB interfaces comply with USB
Specification Rev. 1.0, and are fuse-protected.
The USB interfaces are accessed through a 10-pin flat-cable
connector, CN11. The adapter cable has a 10-pin connector on one
end and a USB connector on the bracket.
The USB interfaces can be disabled in the system BIOS setup.
2.9 IR Connector (CN1)
This connector supports the optional wireless infrared transmitting
and receiving module. This module mounts on the system case. You
must configure the setting through the BIOS setup.
2.10 External Keyboard Connector (J10)
In addition the the PS/2 mouse/keyboard connector on the PCA-
6175's rear plate, there is also an extra on-board external keyboard
connector. This gives system integrators greater flexibility in design-
ing their systems.
Chapter 2 Connecting Peripherals
29
2.11 External Suspend Switch Lead (SMI) (J3)
This allows the user to manually place the system into a suspend
mode or "Green" mode when the system is not in use. System activity
is decreased to save electricity and prolong the life of certain compo-
nents. The 2-pin connector connects to the case-mounted suspend
switch. If you do not have a switch for the connector, you may use the
"turbo switch", because it does not have any other function. SMI is
activated when it detects a "short to open" moment. Therefore, leaving
it shorted will not cause any problems. It may require one or two
pushes
depending on the position of the switch. Wake-up can be controlled
by settings in the BIOS, but the keyboard will always allow wake-up.
(The SMI lead cannot wake up the system.) If you want to use the
SMI connector, the "Suspend" switch in the Power Management
Setup of the BIOS software should be on the default setting "Enable".

Programming the
Watchdog Timer
The PCA-6175 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.
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 time interval
value. The value range is from 01 (hex) to 3F (hex), and the related
time interval is 1 sec. to 63 sec.

direction is correct (pin 1 of the DiskOnChip® 2000 is aligned with
pin 1 of the socket).
3. Power up the system.
4. During power up you may observe the messages displayed by the
DiskOnChip® 2000 when its drivers are automatically loaded into
the system's memory.
5. At this stage the DiskOnChip® 2000 can be accessed as any disk in
the system.
6. If the DiskOnChip® 2000 is the only disk in the system, it will
appear as the first disk (drive C: in DOS).
7. If there are more disks besides the DiskOnChip 2000, the DiskOn-
Chip® 2000 will appear by default as the last drive, unless it was
programmed as the first drive. (Please refer to the DiskOnChip®
2000 utilities user manual.)
8. If you want the DiskOnChip® 2000 to be bootable:
a . Copy the operating system files into the DiskOnChip® by using
