The National Instruments GPIB-VXI/C is a C-sized VXIbus module that bridges IEEE 488 (GPIB) and VXIbus architectures, enabling GPIB controllers to communicate with and manage VXI instruments as standard GPIB devices. Operating as the Slot 0 Resource Manager, it handles VXIbus startup, configuration, self-test, and initialization while controlling message-based, register-based, and VME devices. The module embeds all necessary control functionality in firmware, supporting high-speed shared memory block transfers and functioning as both Message-Based Commander and Servant.
