National Instruments 778783-02

The National Instruments part number 778783-02 refers to the PXI-8464/2 PXI-CAN Interface, a robust solution designed for high-performance CAN communication. Featuring two ports and a maximum transfer rate of 1000 kb/s, this interface is equipped with an ISO 11898 physical layer and utilizes a Philips SJA1000 CAN controller, ensuring reliable data transmission. The dedicated Intel 80386EX microprocessor allows for efficient timed CAN frame transfer, supporting full-load receiving capability of up to 1 Mb/s. This model is compatible with various transceivers, including TJA1041, TJA1054A, and AU5790, enhancing its versatility for different application requirements.

The 778783-02 offers real-time support for LabVIEW and facilitates seamless integration with NI-CAN software, which provides two programming interfaces: a channel API for simplified access to the CAN bus using engineering units, and a frame API for low-level access that allows direct reading and writing of raw frames on the network—ideal for precise testing and simulation scenarios. Each port is fitted with a 9-pin male D-Sub (DB9) connector that adheres to the CiA DS 102 recommended pinout.

This interface is designed for diverse communication standards, supporting low-speed/fault-tolerant CAN hardware with communication rates of up to 125 kbps, and single-wire mode operations at rates up to 33.3 kbps. Typical operating current is 900 mA, and the device features dimensions of 6.3 x 3.9 inches. The operational temperature range is specified from 0 to 55 °C, and hardware configuration can be conveniently managed using the Measurement & Automation Explorer (MAX) tool.
