The NI GPIB-1014 is a VMEbus interface card that enables IEEE 488 GPIB instruments to communicate with VMEbus-based computer systems. It provides full IEEE 488.1-1987 controller functionality—including normal and extended talker, listener, serial and parallel poll, service request, and remote programming—allowing seamless instrument control and data acquisition across heterogeneous test architectures.
Technical Specifications
