General Information
The HS-4500 is a Little Board size Embedded Pentium
®
MMX™ Industrial Single
Board (I.S.B.) The board design combine together with all necessary input and
output effects interfaces which makes it an ideal all-in-one industrial single board
computer. The board design with 100 MHz internal bus clock rate architecture.
With the PCI-bus slot for provides to a PCI add-on card where necessary. One set
of PC/104-bus connector for industrial PC/104 board add-in. For GPS system
application, the board provides a 2x10 pin-field internal I/O connector for easy
add-in Rockwell’s "Jupiter" Global Positioning System (GPS) Receiver. The board
also design with an ESS
®
Solo1 3D sound interface which provides an ideas
sound adapter in any sound application. The IDE interface with DMA33 access of
mode 4 to IDE drive interface architecture, supports with maximum 33.3 MB/sec
in data transfer rating to 2 pieces IDE drive connection. The board also provides a
on-board 10/100-based LAN for easy network connection.
A single Flash chip holds the system BIOS, and you can change the Flash BIOS
by the Utility Update. Advanced IR also provides a faster data transmission. You
can also use the DOS version of the "DiskOnChip

" socket by issuing commands
from the DOS prompt without the necessity of other software supports up to
144MB.
The board design with 69000 VGA provides internal connections to VGA Monitor
and-or Flat Panel. The VGA supports up to 1280x1024 256 colors resolution.
The HS-4500 support BEDO, EDO, FPM DRAM and SDRAM memory with 2 pcs
SIMM sockets and one DIMM sockets. This gives you the flexibility of configuring
your system from 1 to 384 MB DRAM by using the most economical SIMMs and
DIMM memory modules for its on-board system DRAM.
If a non-expect program cause halts, the onboard Watch-Dog Timer (WDT) will
automatically reset the CPU or generate an interrupt. The WDT is designed with
pure hardware and doesn’t need any arithmetical functions of a real-time clock
chip. This ensures the reliability in an unmanned or standalone system.
