National Instruments 780687-01 PXI CAN Interface Module 

National Instruments part number 780687-01 is an identifying part number for the PXI-8512 PXI CAN Interface Module. The 780687-01 offers a single port that is designed for optimal connectivity. This Interface Module combines low-level microcontroller programming performance with the power of Windows and the development capabilities of the LabVIEW Real-Time operating system. The DMA engine, powered by patent-pending NI-XNET technology, reduces system latency from milliseconds to microseconds, addressing a common issue with PC-based CAN, LIN, and FlexRay interfaces. The database engine and integrated NI-XNET utilities streamline frame-to-signal translation while maintaining maximum performance. 

The 780687-01 supports industry-standard CAN, LIN, and FlexRay signal database formats, including FIBEX, CANdb (.DBC), LDF, and NI-CAN NCD, simplifying integration into network design workflows. Real-time processing of CAN, LIN, and FlexRay signal and frame data is essential for precise hardware-in-the-loop simulation and rapid control prototyping. Code management is made simpler between platforms with LabVIEW programs for NI-XNET devices, as they operate on both Windows and LabVIEW real-time targets without requiring code modifications. This same code can be reused in various form factors, including PXI, PCI, NI CompactDAQ, and NI CompactRIO.

 With support for up to 192 hardware-accelerated frames, the NI 780687-01 CAN Interface reduces repetitive processing on the host system, freeing up CPU time for other tasks. NI RTSI synchronization support allows NI-XNET interfaces to integrate and synchronize with other NI products, including data acquisition, PXI modular instrumentation, vision, and motion. The RTSI/Front Panel Sync Connectors of the device feature 7 input/output trigger lines and 1 input/output clock line. These lines are TTL compatible. At power-on, the state of the lines is set to input (High-Z). The response to triggers is based on rising edge triggers.
