Applications
Applications for the M203 Board include embedded digital panel meters, customized instrumentation
displays, temperature monitoring, high resolution DVM’s, weigh scales, signal conditioners, laboratory
data-logging, process monitors, portable/field troubleshooting and calibration.
Configuration & Outline Drawing
All MB203 boards include a DB25 pin connector that plugs directly into the parallel printer port of a
desktop or laptop PC computer for operation, initial setup & calibration. After initial setup, the board may
be unplugged from the PC and operated in the stand-alone mode. Depending on a specific application,
each board can be readily modified and populated with different components for other modes of
operation.
