The NI PXI-8512/2 is a 2-port, high-speed controller area network (CAN) PXI interface for developing CAN applications in NI LabVIEW, NI LabWindows/CVI, and C/C++ on Windows and LabVIEW Real-Time OSs. As part of the NI-XNET platform, the PXI-8512/2 works well in applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals, such as hardware-in-the-loop simulation, rapid control prototyping, bus monitoring, automation control, and more.

NI-XNET: One API, Many Embedded Networks and Form Factors
The NI-XNET platform combines a series of high-performance CAN, LIN, and FlexRay interfaces with the NI-XNET API, a common set of easy-to-use functions for reading and writing CAN, LIN, and FlexRay frames and signals in many different platforms including PXI, PCI, NI CompactDAQ, and NI CompactRIO.

Top Performance With Less Programming
NI-XNET interfaces bring together the performance associated with low-level microcontroller programming and the speed and power of Windows and LabVIEW Real-Time OS development. The patent-pending NI-XNET device-driven DMA engine reduces system latency, a common pain point for PC-based CAN interfaces, from milliseconds to microseconds. The engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, freeing host processor time for processing complex models and applications.
