The module CW-101 extends our range of products in the field of bus technology. This module makes it is possible to quickly and easily connect a CAN bus to a PC via a USB interface. Designed for applications in automation technology, robotics, test benches as well as the automotive and commercial vehicle industry. This module offers the user a simple and cost-effective CAN interface – without the need to install a driver.

The CAN USB adapter CW-101 implements the ISO Standard 11898-2 (high speed CAN) with data transmission rates from 125 kbit/s up to 1 Mbps. In addition, data transmission rates more frequently used in automation of 20, 50 and 100 kbit/s are also supported. This sees, both 11 bit and 29 bit CAN identifiers evaluated.

In conjunction with the software CW-901 the CAN USB interface not only facilitates simple data logging and analysis, but also targeted (synchronized) transmissions of single CAN messages. Direct support for the widely used CANdb data format (DBC) is also optionally available.

The standard connection between the CAN bus adapter and the CAN bus is achieved by means of a D-Sub 9 connector. A special CAN mini USB connector is also available for our CW-200 series used to monitor machine and plant applications — other optional cable and connector sets are also possible.


  • Plug and Play, no USB driver required 
  • Runs under Windows, Linux and Mac
  • No power pack required
  • API for C/C++ and C# to integrate in proprietary programs
  • Quick and easy to install and configure (e. g., in conjunction with the software CW-901)
  • Very favourable price-performance ratio
  • Particularly suitable for mobile use thanks to extremely compact dimensions
