NI USB-847x CAN Interfaces |
National Instruments USB-847x modules provide Hi-Speed USBinterfaces for connecting your PC to Controller Area Network (CAN) networks and devices. With the optional hardware synchronization versions that feature a 3-pin COMBICON synchronization connector, you can synchronize the internal hardware time base with other devices such as USB-CAN; USB-LIN; and NI data acquisition, motion, and vision, with 1, 10, or 20 MHz clocks. Synchronization eliminates clock drift between devices and enables triggering between devices for correlating CAN data with data from other devices. NI USB-847x interfaces are ideal for a wide variety of applications, including monitor and logging in-vehicle networks, bus load monitoring, device validation with synchronized data acquisition, CAN device development and test, and correlating CAN and LIN data with external measurements. The convenient all-in-one design features a captive 2 m USB cable and built-in transceiver, requiring no extra cables or accessories to get applications running quickly. With hardware timestamping, you can log messages with microsecond-accurate timestamps for reconstructing network events and correlating data across synchronized devices. All USB-847x interfaces use an industry-standard 9-pin male D-Sub (DB9) connector to interface to the CAN bus. Hi-Speed USB connectivity ensures no dropped frames, even under 100 percent bus loads. Hardware-based error checking helps identify bus-level message problems. |
