CAN simplified

DEWESoft USB CAN 2.0b interfaces are powerful yet easy to use. Plug and play functionality will bring you zero configuration, meaning you'll be acquiring and decoding CAN messages in no time.

OBDII support
J1939 support
CCP/XCP support

Fast and Reliable

All CAN interfaces support transmitting and receiving CAN 2.0b data at full speed of 1Mbit/s per each channel.

All CAN channels are isolated for use in noisy environments and for maximum signal quality.

Robust housing CNC-ed out of a single block of aluminium provides ruggedness and assures operation in harsh environments. All CAN instruments are IP65 rated and operate in -20°C to +60°C temperature range.

Vehicle CAN recording

Bundled with Dewesoft X Software our CAN interfaces are perfect data recorders for in-vehicle measurements. System offers:

  • advanced CAN recording, storing and analysis
  • ONLINE monitoring and decoding of CAN messages
  • visual display for displaying CAN data
  • ONLINE math and analysis of CAN channels
  • DBC file decoding
  • OBDII on CAN, J1939 and J1587 support
  • CAN output


Sync and Expand

CAN interfaces come installed with a synchronization port which allows for hardware synchronization with other DEWESoft DAQ instruments like SIRIUS, KRYPTON or DEWE-43.

CAN interfaces SYNC port

CAN interfaces can be easily extended to add time and position information to the recorded CAN messages for easier post processing and/or video information with DS-CAM or any other supported cameras. Of course all sources are perfectly synchronized.
