The NI USB-8472 is a 1 Port Low-Speed, USB CAN Interface, specializing in automotive networking products. Its part number is 779790-01, indicating its unique identification within the range of products offered by National Instruments.
This interface is designed to cater to advanced networking needs in the automotive sector, featuring advanced filtering modes such as self-reception and listen-only, alongside Low-Speed/Fault-Tolerance capabilities. These features are crucial for ensuring reliable data transmission and reception across automotive networks, even under conditions where network integrity might be compromised.
The USB-8472 is built on a low-speed/fault-tolerant physical layer, which connects the CAN controller to bus wires with integrated physical layer transceivers. This ensures a robust connection and data communication pathway, essential for automotive applications that require high levels of data integrity and fault tolerance.
Electrical isolation is another key aspect of this product, offering protection up to 500V. This feature safeguards the device and the network from potential electrical failures, providing an additional layer of reliability.
Compatibility with Microsoft Windows and the NI-CAN driver software ensures that users can easily integrate the USB-8472 into their existing systems without the need for extensive modifications or compatibility checks. Additionally, the product supports various APIs including Visual Basic 6.0, Microsoft Visual C/C++, Borland C/C++, and NI LabVIEW, making it versatile for different development environments.
Utilities such as NI Spy and Bus Monitor are included, offering users powerful tools for diagnostic and monitoring purposes. These utilities are invaluable for ensuring that the CAN network operates as intended, allowing for real-time tracking and troubleshooting of network activities.
The interface features software-selectable termination, providing flexibility in how the device is configured within the network. The use of the Philips SJA1000 CAN controller underscores the device’s reliability and performance, ensuring compatibility with ISO 11898 CAN protocols and the J1939 protocol.
