ADAC Corporation manufactures a wide range of data acquisition products, including high speed A/D boards with C40 comm ports to interface directly to most C40 DSP cards. In 1974, ADAC Corporation invented the worlds first plug-in data acquisition boards. Designed for the Data General NOVA and the Digital Equipment Corporation PDP-8 computers, ADAC's 500/DGC and 600/8E Series were the first data acquisition boards that plugged directly into the host computer bus. This innovation eliminated the previous requirement for expensive front-end data acquisition systems. With 8 analog inputs, 2 analog outputs and a mixture of digital I/O, these boards set the standards that all major PC data acquisition companies continue to follow today.
