Introduction
The SBC-455 is an all-in-one single board 486 computer with an on-
board flat panel/CRT SVGA controller. It packs all the functions of
an industrial computer and its display capabilities onto a single, half-
size card. This means the SBC-455 is your absolute best solution for
embedded applications.
The on-board PCI-bus, flat panel/CRT SVGA controller uses the
CHIPS 65548 chipset with up to 1 MB of video memory. This chipset,
used with the local PCI-bus, enables 32-bit graphic throughput at up
to 33 MHz. Excellent for display-intensive applications, it supports
various LCD types including TFT, STN, B/W, and EL.
Another feature of the SBC-455 is the inclusion of a high speed, local
bus IDE controller. This controller supports (through ATA PIO) mode
3 and mode 4 hard disks, enabling data transfer rates in excess of 11
MB/second. 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 IDE boost performance improvements.
On-board features 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 16 KB of on-chip
cache memory, the SBC-455 includes an extra 128 KB of second level
on-board cache memory.
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. This ensures reliability in unmanned or standalone
systems.
The SBC-455 supports 5 V EDO DRAM. It also provides two 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 64 MB of DRAM using the most economi-
cal combination of SIMMs.

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.
