National Instruments PXI-8464-2

The National Instruments PXI-8464/2 is a dual-port, software-selectable PXI-CAN interface designed to facilitate high-performance communication in industrial applications. Featuring a maximum transfer rate of 1 Mb/s and supporting up to 100% load receiving capability, this interface utilizes the ISO 11898 physical layer and is controlled by a Philips SJA1000 CAN controller paired with an Intel 80386EX microprocessor for precise timing in CAN frame transfer. The PXI-8464/2 accommodates high-speed, low-speed, and single-wire configurations, making it versatile for various device communications, including compatibility with transceivers such as the TJA1041, TJA1054A, and AU5790. With a 9-pin male D-Sub (DB9) connector for each port, it adheres to the pinout specified by CiA DS 102. The device supports communication speeds of up to 125 kb/s in low-speed mode and 33.3 kb/s in single-wire mode. Users can easily implement multiple-transceiver hardware for applications spanning different communication standards, drawing a typical current of 900 mA. The PXI-8464/2 integrates seamlessly with NI-CAN software, which provides both channel and frame APIs tailored for application programming and database management, enhancing testing and simulation efficiency. Configuration of the hardware is facilitated through the Measurement & Automation Explorer (MAX) tool. The compact interface measures 6.3 x 3.9 inches and operates within a temperature range of 0 to 55 °C. Although the PXI-8464/2 has been marked as obsolete, it remains available for purchase and repair through Apex Waves.
