National Instruments 779792-01 High-Speed CAN Interface Device

The National Instruments 779792-01, part of the USB-8473 model series, is a 1-port, high-speed Controller Area Network (CAN) interface device tailored for developing CAN applications. This device offers versatility in data handling by facilitating many modes such as listen-only, self-reception (echo), and advanced filtering modes. Fitted with NI-CAN driver software, it provides a frame-based API for quick creation of applications. Designed to assure compatibility with automotive CAN standards, it meets the electrical and physical requirements of in-vehicle networks.

In order to integrate with PCs seamlessly, the 779792-01 interface provides Hi-Speed USB connectivity. This allows users to connect to CAN, or Local Interconnect Network (LIN), networks and devices. It can be configured to have hardware synchronization capabilities, which allow it to synchronize with other devices at different clock rates. Accurate data correlation is ensured by this synchronization, which also removes clock drift and permits exact triggering across devices.

The 779792-01 device is used in bus load monitoring, device validation, CAN device development and testing, and LIN and CAN data correlation with external measurements. It is perfect for recording, validating, and monitoring in-vehicle networks. Fast setup without the need for further equipment is made possible by its all-in-one design, which includes a captive 2 meter USB cord and an integrated transmitter. Hardware timestamping provides microsecond-accurate timestamps, making it easier to reconstruct network events and correlate data amongst synchronized devices.

The 779792-01 ensures dependable connectivity with its industry-standard 9-pin male D-SUB connector for CAN bus interface. Even with maximum bus loads, its Hi-Speed USB interface ensures that no frames are dropped, and hardware-based error checking helps to find message issues at the bus level.

In automotive applications, synchronization capabilities are provided by the 779792-01 for analog, digital, CAN, and LIN measurement integration. Devices can exchange timing and triggering signals to achieve true hardware synchronization with optional hardware synchronization. Testing accuracy is increased by this deterministic synchronization, which guarantees exact correlation between trigger signals and replies.

The Windows-compatible NI-CAN driver software offers a comprehensive API and examples for a number of programming languages.
