SBC-411/411E User Manual
Introduction
The SBC-411/411E is an all-in-one single board 486 computer with an on-
board PCI Ethernet interface (SBC-411E). It packs all the functions of an
industrial computer and its display capabilities into a single, half-size card.
This means the SBC-411/411E is your absolute best solution for embedded
applications.
The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet controller
supports remote boot ROM functions (SBC-411E only).
The SBC-411/411E supports the M-Systems DiskOnChip 2000 (optional)
which is a new generation of high performance single-chip Flash Disk. It
provides a Flash Disk (as a BIOS expansion) which doesn't require any
bus, slots, or connectors. It is also the optimal solution for Single Board
Computers because of its small size, easy integration, plug-and-play
functionality, and its low power consumption. The DiskOnChip is
available in capacities from 2MB to 72MB and fits in a standard 32-pin DIP
socket.
Another feature of the SBC-411/411E 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 boost IDE performance.
Onboard features include two high speed RS-232 serial ports, one bidirec-
tional 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-411/411E includes an
extra 128 KB of L2 onboard cache memory.
If program execution is halted by a program bug or EMI, the board's
watchdog timer can automatically reset the CPU or generate an interrupt.
This ensures reliability in unmanned or standalone systems.
