Compact interface with galv. isolated CAN- and a RS232-interface on USB 2.0

Key Features

  • 1× galv. isolated CAN interface acc. to ISO 11898 and 1× RS232
  • Connection via USB 2.0
  • Free configuration of baud rate, incl. 800 Kbit/s
  • Powerful 32-bit microcontroller
  • CODESYS Gateway-driver available
  • Multi-Thread API for own applications
  • Driver for Windows 2000 up to Windows 10 with 32- and 64-bit


Housing and interfaces
It is housed in a compact plastic case and offers a CAN channel and a RS232 channel. CAN is of CiA standard D-Sub9 design. Its USB 2.0 interface enables the CANfox to be used at any laptop, embedded PC or desktop PC. Once you have instal­led the driver you will benefit from hot plug and play, which is a con­nec­tion of device to PC without restart. Con­sequen­tly, CANfox® offers all necessary interfaces located in a tiny case for mobile or stationary use.

More performance, less costs
It is a powerful device within the Sontheim interface group with its 32-bit micro­con­trol­ler for data-handling. However, the CANfox® is meant to be a flex­ible and very inexpensive tool.

Thus, you can configure the baudrate via software and adapt it to your processes.

Comprehensive software support
Of course, CANfox® is supported by all Sontheim software like CANexplorer 4 for CAN bus dia­gnos­tics, or MDT® for vehicle app­li­ca­tions like dia­gnos­tics or End-of-Line processes. Additionally, with purchasing an interface you get the pro­gram­ming interface (API) for integrating the CANfox® into your own software. There is also a CODESYS sup­port implemented in order to use the de­vice for PLC and motion control tasks. Use it as a programming gateway for CODESYS-based PLCs or for downloading programms directly out of a CODESYS programming en­vironment.
