The NI VXI-MXI w/ INTX Module and SB-MXI Interface Card Kit extends VXIbus architecture beyond the mainframe, enabling high-speed communication and control between a VXI chassis and a host computer. The INTX daughter card enhances interrupt handling for improved system responsiveness. This kit delivers register-based data transfer with DMA support and is built for complex automated test systems and demanding data acquisition applications.
