National Instruments 781365-01 LIN Interface 

National Instruments part number 781365-01 is an identifying part number for the PCI-8516, an LIN Interface. This LIN Interface module comes with 2 ports. The NI 781365-01 serves as a Local Interconnect Network (LIN) interface tailored for application development utilizing the NI‑XNET driver. It is particularly adept in scenarios necessitating real-time, high-speed management of numerous LIN frames and signals, including hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, and automation control. With its NI‑XNET device-driven DMA engine, the PXI‑8516 facilitates seamless movement of LIN frames and signals between the interface and user programs without CPU interrupts. 

This capability reduces message latency, liberates host processor resources, and enables efficient processing of intricate models and applications. The NI PCI-8516 employs controller zone systems across a diverse range of applications, spanning from small medical devices to large earth-moving equipment. To maximize the efficiency and cost-effectiveness of CAN across these varied applications while maintaining software and functional compatibility, users can leverage a range of physical layers optimized for different standards. 

The physical layer of a CAN implementation determines the types of cabling, electrical signal levels, and termination schemes utilized. The transceiver, a key component connecting a CAN controller to the system, plays a crucial role in this process. The PCI-8516 features a 2-port fast LIN interface (20 kbit/s per port) equipped with onboard ATA6620 transceivers. It also includes the NI-XNET driver, enabling the development of edge and signal applications in LabVIEW, LabWindows™/CVI, and C/C++. Furthermore, the NI-XNET device-driven DMA engine links the LIN bus to host memory, minimizing message latency.
