The NI 9861 is a 1-port, low-speed controller area network (CAN) NI CompactDAQ and NI CompactRIO interface for developing CAN applications in NI LabVIEW, NI LabWindows/CVI, and ANSI C/C++. As part of the NI-XNET platform, the NI 9861 works well for applications requiring high-speed manipulation of hundreds of CAN frames and signals. You can perform this manipulation while taking other data acquisition measurements in the same NI CompactDAQ hardware platform or while performing low-level FPGA control and embedded monitoring in the same NI CompactRIO chassis.
The NI 9861 and NI-XNET products are ideal for standardizing on CAN communication. By using the same software API for programming networks on PXI, PCI, NI CompactDAQ, and NI CompactRIO, you can significantly reduce development time through maximum code reuse. Real-time testing applications like hardware-in-the-loop testing and simulation are also ideal for the NI 9861 because it is part of the NI-XNET family of products and works with the NI VeriStand software environment for configuring real-time testing applications.
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.
