GENERAL INFORMATION

The PCM-MIO is a versatile, PC/104 analog input, analog output, and digital I/O board designed for high accuracy and high
channel count analog and digital I/O. The board is based upon Linear Technologies’ state of the art precision converters
and voltage references which require no external callibration.
