The PXI-8513 is a software-selectable Controller Area Network (CAN) interface for developing applications with the NI-XNET driver. NI-XNET Software-Selectable CAN Interfaces offer the best flexibility for CAN development with onboard transceivers for High-Speed/Flexible Data-rate, Low-Speed/Fault Tolerant Single Wire CAN as well as any external transceiver. The PXI-8513 excels 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. The NI-XNET device-driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts.
