The CANsub series lets you stream CAN bus data in real-time via USB or Ethernet, combining professional-grade CAN FD performance with a built-in LCD display and zero software installation.

The free webCAN application is hosted directly on the CANsub. Simply enter the device URL in a browser to get started. This allows you to instantly send and receive CAN frames, decode DBC data and plot CAN signals from any connected PC, tablet or smartphone, even when working offline.

The integrated LCD display provides real-time device and CAN information, while USB and Ethernet connectivity enable flexible access to CAN data from laptops, tablets and smartphones.

The CANsub series is available in two variants: the CANsub.2 with 2 x CAN FD channels via dual DB9 connectors, and the CANsub.4 with 4 x CAN FD channels via a DB25 connector.

For advanced applications, the CANsub provides an open REST/WebSocket API, making it easy to build custom software, dashboards and integrations, with plug-and-play support for tools such as Python and SavvyCAN.

Ideal for CAN bus diagnostics, OEM development, field service, automation, testing, monitoring and dashboard applications.
