Single-board computer VSX104 of the firm Tri-M adaption for OpenSCADA
Begin: 05 (Maj) 2008
Participants: Roman Savochenko
Description: VSX104 is a single-board computer of the form-factor PC/104 of the firm Tri-M. The computer had attracted attention by the reason of low price and low power consumption (< 2W) and followed low heating. But by using the processor "Vortex86SX-300 МГц" here needs specific points to forming of the OS environment, but here used CPU instructions set of i486 and the mathematical coprocessor lack.

Hardware specification of the board:

Central processor: DM&P SoC Vortex86SX-300 MHz
Operational memory: 128 МБ DDR2 RAM, soldered to the board
Permanent memory: slot CompactFlash Type I, microSD and 2 ports EIDE (Ultra DMA 100)
Video subsystem: no
Audio subsystem: no
Interfaces/ports: 10/100Mbps Ethernet; 4 RS-232 serial ports; 2x USB 2.0; PS/2 keyboard and mouse, LPT, Redundancy, SPI
Power supply: +5VDC ±10% @ 370mA
Operating conditions: -40 ... 85°C
DAQ: 1 port 16-bit GPIO

For now there is not a solution based on the board but planed to assemble for it a environment, possible for an autonomous control resources system.
