National Instruments (NI) is launching USB modules for high-speed and

low-speed/fault-tolerant Controller Area Network (Can) and Local Interconnect Network (Lin) monitoring, logging and testing, combining the quality and performance of NI Can software and hardware with the benefits of Hi-Speed USB. With a low price point and a synchronisation option, these devices give engineers an easy, cost-effective and portable way to connect their PCs to Can and Lin devices and networks for device validation, test and in-vehicle data logging.

The new USB-847x interfaces not only make it easy to link PCs and laptops to automotive networks, but each interface is also available with a synchronisation option that allows it to share start triggers and timestamps with other USBCan and Lin interfaces, as well as with data acquisition, vision and motion devices such as NI Compactdaq and bus-powered M series multifunction data acquisition modules for USB. Users can synchronise Can and Lin data with multiple types of measurements with microsecond resolution. An engineer conducting an in-vehicle noise, vibration and harshness test, for example, can monitor sensors and then determine the state of ECUs on the network if test thresholds are exceeded.

NI’s USB-8476 Lin interfaces are the first Lin devices from the company. Lin, a single-wire communication bus, is cost-effective for networking automotive smart sensors and actuators that do not require the bandwidth and versatility of Can. The Lin interfaces can function in master, slave and monitor modes and are fully compatible with 1.3, 2.0 and J2602 Lin standards.

All six of the interfaces feature Hi-Speed USB technology. An onboard hardware buffer, combined with the 40X improvement in bandwidth of Hi-Speed USB over

full-speed USB, ensures that the USB modules do not drop frames, even while transmitting and receiving 100percent bus loads at speeds up to 1Mb/s. The interfaces are bus-powered, with integrated transceivers and a captive USB cable, for rugged, plug-and-play functionality.

The new USB modules include NI-Can driver software for rapid application development.

With a powerful frame-based API, engineers using NI-Can can develop and operate applications in a variety of programming environments, including National Instruments Labview, Labwindows/CVI and Measurement Studio, as well as Microsoft C/C++ and Visual Basic.
