National Instruments 778783-01

The National Instruments 778783-01 PXI-CAN Interface is a highly efficient interface module designated for use with the PXI-8464/1 system, designed to connect seamlessly with the Controller Area Network (CAN). This 3U module adheres to both PXI and CompactPCI standards, making it suitable for interfacing with individual low-speed CAN devices. The module is equipped with selectable transceivers, including TJA1041, TJA1054A, and AU5790, and features a single DB9 male connector for I/O. It supports a maximum transfer rate of 1,000 kb/s and operates with a typical power requirement of 800 mA at +5 VDC.

The NI 778783-01 is compatible with National Instruments’ NI-CAN software, facilitating application development on Windows 2000/NT/XP/Me/98 platforms. This software includes both a channel API and a frame API, providing flexibility for users to work with CAN bus networks using engineering units or to access raw frames directly for precise control. The drivers are 32-bit and support integration with development environments such as NI LabVIEW, LabWindows/CVI, Microsoft Visual C/C++, Borland C/C++, and Visual Basic 6.

For optimal performance, it is recommended to verify the total termination resistance of the network or individual devices, aiming for a resistance of 100 to 500 Ω in low-speed networks to ensure adequate signal integrity. The NI 778783-01 represents a robust solution for integrating automated I/O with built-in signal conditioning within CAN environments.
