Single-board computer MOPSlcdLX of the firm Kontron adaption for OpenSCADA
Begin: 03 (Mar) 2006
Participants: Roman Savochenko
Description: MOPSlcdLX is a single-board computer of form-factor PC/104. The computer had attracted attention by some low price, by ordinal conditions of the exploitation and then lower heating.

Hardware specification of the board:

Central processor: AMD LX800™ 500 MHz, fanless
Operational memory: DDR-RAM-SODIMM socket
Permanent memory: IDE (44) port
Video subsystem: built-in graphic with support output to flat panels, CRT and LCD
Audio subsystem: no
Interfaces/ports: 10/100Mbps Ethernet (Intel® 82551ER); 2 RS-232 serial ports; 2x USB 2.0; PS/2 keyboard and mouse, Floppy, LPT
Poser supply: +5VDC ±10% @ 1A
Operating conditions: 0 ... 60°C

The board had used for testing of creation operator stations/panels with OpenSCADA into like environment. Latter there had occur problems series with the board:

  • The clock's battery lack then it needs to setting the time at any starting or setting the external battery. At that the BIOS settings stored not in CMOS but in FLASH, it is kind good but if the BIOS configuration reset impossible then it is too bad.
  • A problem into the interruption scheme which cause to block all or mostly adjacent interruptions at the module "geode_aes" loading.
  • In some time the video-card or it's video-output burned but the configurations of BIOS stored into FLASH and there impossible to return its, for fix possible disabled the video into the BIOS. Also the BIOS do not support of forwarding self interface to a COM-port. Will try use CRT here, when it emerged.
  • The high-precision counter (HPET) lack, that surprisingly and make this board unusable for real-time systems but ordinal counter can provide lag about 4ms.

For now base on this board preparing "The program oscilloscope" why it was successfully downloaded by the modern firmware with kernel "std-def" and addition board DMM-32X-AT installed, about that see above.
