Overview

Product overview

Key product information and technical features.

The USB-8473 is a USB-connected CAN interface for developing CAN applications, including work with automotive networks. Its single port uses the high-speed CAN physical layer.

NI-CAN provides the frame-based programming interface. NI documents USB-8473 and USB-8473s separately; the synchronization capabilities of the USB-8473s should not be attributed to the standard USB-8473.

  • Listen-only mode for CAN monitoring.
  • Self-reception (echo) mode.
  • Advanced filtering modes.
  • Hardware timestamping with 1 µs resolution, as documented for NI USB-847x CAN interfaces.
