Not recommended for new designs. NI recommends the USB-8502/2.

The USB-8473s module is a 1-port high-speed CAN interface for connecting PCs to CAN networks and devices. It includes NI-CAN driver software, which provides a powerful, frame-based API for rapid application development.

Advanced Synchronization
The USB-8473s features a 3-pin COMBICON synchronization connector for synchronizing the internal hardware timebase with other devices, including USB CAN and LIN interfaces, as well as NI data acquisition, motion, and vision devices, with 1 MHz, 10 MHz, or 20 MHz clocks. Synchronization eliminates clock drift between devices, and you can trigger between devices for correlating CAN data with data from other devices.

All-in-One Design
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. The USB-8473s is bus-powered and features standard electrical isolation up to 500 VDC (withstand, 2 s max) channel-to-bus.

Hardware Timestamping
With hardware timestamping, you can log messages with microsecond-accurate timestamps for reconstructing network events. The USB-8473s interface uses a 9-pin male D-SUB (DB9) connector to interface to CAN.

Advanced Functionality
The USB-8473s uses the Philips SJA1000, which provides advanced functionality, such as listen-only mode, sleep/wakeup mode, error counter access, and self-reception (echo) mode.
