The IOC-DAADIO-VME board is a low cost, high functionality, analog/digital I/O product. The board combines the functionality of digital-to-analog conversion (DAC), analog-to-digital conversion (ADC), and parallel input/output interface (PIO) on a double-height (6U) VMEbus board. Any of these functions (DAC, ADC, PIO) can be implemented singularly or in combination to tailor the board to specific needs.
