The National Instruments PCI-8511 (Part Number: 780682-01) is a high-performance CAN interface device designed for applications requiring rapid and continuous control of multiple CAN signals. This versatile model excels in scenarios such as equipment simulation, rapid control prototyping, bus monitoring, and automation control. Equipped with the NI-XNET driver, the PCI-8511 utilizes direct memory access (DMA) to enable seamless communication between its internal processor and the application software, minimizing CPU interference. The NI-XNET interface combines the efficiency of low-level microcontroller programming with the robustness of Windows and LabVIEW Real-Time development environments. The patent-pending NI-XNET hardware-accelerated DMA engine significantly reduces system latency for PC-based CAN, LIN, and FlexRay interfaces, achieving response times from milliseconds to microseconds.

The device supports industry-standard signal databases, including FIBEX, CANdb (.DBC), and LDF, thereby streamlining integration into embedded system workflows. Its driver-level database engine and bundled NI-XNET utilities facilitate efficient frame-to-signal interpretation while maintaining high performance. The PCI-8511 features one port, equipped with NXP TJA1054A or TJA1055T transceivers, allowing for low-speed and fault-tolerant CAN communication with baud rates ranging from 10 Kbps to a maximum of 125 Kbps. The device includes seven configurable input/output trigger lines, a clock line, and utilizes a 9-pin male D-SUB connector for easy connectivity. Power requirements are +5 VDC and +3.3 VDC at 640 mA and 940 mA respectively. With dimensions of 4.2 inches by 6.6 inches and a weight of 0.22 pounds, the PCI-8511 is compact and lightweight. It comes with a two to three-year warranty, and comprehensive user and maintenance manuals are available for download.
