Introduction
The SBC-590 is an all-in-one single board Pentium computer with an
on-board SVGA controller, with PCI-bus and ISA-bus support. It
packs all the functions of an industrial computer with display capabili-
ties on a single full-size card. The SBC-590 is fully PC/AT compati-
ble, so your software will run without modifications.
The on-board PCI-bus SVGA controller uses the ALG 2032 chipset
with 1 MB shared memory. This chipset, used with the local PCI-bus,
enables 32-bit graphic throughput and has a built-in Standard
Feature Connector. These features make the SBC-590 particularly
suited for graphics intensive applications.
Another feature of the SBC-590 is the inclusion of a high speed local
bus IDE controller. This controller supports (through ATA PIO)
mode 3 and mode 4 hard disks, which enables data transfer rates in
excess of 11 MB/sec. Up to four IDE devices can be connected,
including large hard disks, CD-ROM drives, tape backup drives or
other IDE devices. The built-in enhanced IDE controller provides a
4-layer 32-bit posted write-buffer and a 4-layer 32-bit read-prefetch-
buffer to accomplish the IDE boost in performace improvements.
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 Pentium's 16 KB of
on-chip cache memory, the SBC-590 comes with an extra 256 KB or
512 KB of second level memory on-board.
If program execution is halted by a program bug or EMI, the board's
16-stage watchdog timer can automatically reset the CPU or generate
an interrupt, provided the watchdog timer has been programmed in
advance. This ensures reliability in unmanned or stand-alone systems.
The SBC-590 supports 5V EDO DRAM. It also 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 128 MB of DRAM using the most eco-
nomical combination of SIMMs.

Connectors on the board link it to external devices such as hard
disk drives, a keyboard or floppy drives. In addition, the board has
a number of jumpers that allows you to configure your system to
suit your application.

Setting 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 would connect either pins
1 and 2 or 2 and 3.
The jumper settings are schematically depicted in this manual as
follows:
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 representa-
tive before you make any changes.
Generally, you simply need a standard cable to make most
connections.

Safety precautions
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.
