CHAPTER
Introduction
The PCA-6149 is an all-in-one single board 486 computer that includes an
on-board SVGA controller with PCI bus and ISA bus support. It packs
all the functions of an industrial computer, including display capabilities,
on a single full-size card. The PCA-6149 is fully PC/AT compatible, so
your software will run without modifications.
The on-board PCI bus SVGA controller uses the ET4000/W32P chipset
with 1 or 2 MB video memory. This chipset, used with the local PCI bus,
enables 32-bit graphic throughput at up to 33 MHz. The ET4000/W32 also
offers Windows graphics acceleration. These features are excellent for
display-intensive applications.
Another feature of the PCA-6149 is the inclusion of a fast VL bus
enhanced IDE controller. This controller supports mode 3, which enables
data transfer rates in excess of 11 MB/second. Up to four IDE devices can
be connected, including large hard disks (up to 8 GB), CD-ROM drives,
Tape backup drives or other enhanced IDE devices.
On-board features also include two high-speed RS-232 serial ports with
16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy
drive controller. In addition to the 486's 8 KB of on-chip cache memory,
the PCA-6149 includes an extra 256 KB or 512 KB of second level cache
memory on-board.
If program execution is halted by a program bug or EMI, the board's 12-
level watchdog timer can automatically reset the CPU or generate an
interrupt. This ensures reliability in unmanned or standalone systems. The
timer interval of the watchdog timer is set in the BIOS, eliminating jumper
switch setting.
The PCA-6149 provides four 72-pin SIMM (Single In-line Memory
Module) sockets for its on-board system DRAM. These sockets give you
the flexibility to configure your system from 1 MB to 256 MB of DRAM
using the most economical combination of SIMMs.
The CMOS data of the PCA-6149 is backed up in EEPROM, which avoids
data loss, even when the battery fails.
To make using the DX4-100 easy, the PCA-6149 includes an on-board
DC-to-DC converter that automatically switches to 3.3 V.

Safety precautions
Follow these simple precautions to protect yourself from harm and
your PC from damage.
1. To 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. Wear a grounding wrist strap
for continuous protection.
Chapter 1 Hardware Configuration 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 operat-
ing 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.
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 will have three pins, labeled 1, 2
and 3. In this case you connect either pins 1 and 2 or 2 and 3.

application, contact your local distributor or sales representative
before you make any changes.

partially remove the card to make all the
connections.

The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable.
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 the
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.

Enhanced IDE connectors (CN1, CN2)
You can attach four IDE (Integrated Device Electronics) drives to the
PCA-6149's internal controller. The PCA-6149 CPU card has two EIDE
connectors: CN1 and CN2. Each EIDE connector can support two IDE
devices.
CN1 is the first EIDE connector, and must be used first. CN2 is the
second EIDE connector. There must be at least one device attached to
CN1 before CN2 can be used.
Wire number 1 on the cable is red or blue, the other wires are gray.
Connect one end to connector CN1 or CN2 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 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 or CN2.
Chapter 2 Connecting peripherals 17
Floppy drive connector (CN3)
You can attach up to two floppy disk drives to the PCA-6149's on-
board controller. You can use any combination of 5.25"
(360 KB and 1.2 MB) and/or 3.5" (720 KB and 1.44 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.
Parallel port (CN4)
The parallel port is normally used to connect the CPU card to a printer.
The PCA-6149 includes an on-board parallel port, accessed through a
26-pin flat-cable connector, CN4. 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 CN4 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 CN4. Pin 1 is on the right side
of CN4.

Keyboard and PS/2 mouse connectors (J7,
J9)
The PCA-6149 board provides two keyboard connectors. A 5-pin
connector (J7) supports passive backplane applications. A second 6-
pin mini-DIN connector (J9) 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 connec-
tor.

External switches and indicators
Next you may want to install external switches to monitor and control
your CPU card. These features are completely optional —install them
only if you need them.
Power LED and keylock (JP7)
You can connect an LED to indicate when the CPU card is on.
Pin 1 of JP7 supplies power to the LED and Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard. In this state
the PC will not respond to any input. This is useful if you don’t want
anyone to change or stop a running program. Simply connect the
switch between Pins 4 and 5 of JP7. The pin assignments for JP7
appear in the following table:

Turbo LED (JP9)
You can connect a LED indicator across jumper JP9 to indicate when
the CPU is in Turbo mode. Marks on the circuit board indicate LED
polarity.
Reset switch (JP10)
You can connect an external switch to easily reset your computer. This
switch restarts your computer as if you had turned off the power, then
turned it back on. Install the switch so that it closes the two pins of
JP10.
Turbo switch (JP11)
You can connect a switch across the pins of jumper JP11 to change the
CPU between Turbo and non-Turbo mode. When you close (short) the
pins, the CPU card operates at full speed. When you leave the pins
open, the card operates at slow speed for compatibility with older
software.
You can also switch the CPU back and forth between Turbo mode and
non-Turbo mode using the keyboard, but only when jumper JP11 is
open. When jumper JP11 is closed, the CPU is fixed in Turbo mode. To
switch into Turbo mode from the keyboard simultaneously press the
immediately will allow
you to enter Setup.
