Main Features

  • PLUG-AND-PLAY CAN INTERFACES: Our CAN interfaces are robust and easy to use. Simply connect CAN device to the USB port of your laptop or any of our SBOX or KRYPTON CPU computers and device will be recognized automatically and ready to use.
  • 2, 4 or 8 CAN PORTS: CAN devices with 2, 4 or 8 CAN ports are available. Multiple CAN devices can be synchronized together to expand to more CAN ports.
  • HIGH-SPEED ISOLATED CAN: Each of the CAN ports on any CAN device is isolated and utilizes high speed CAN 2.0b standard. 
  • FANLESS CHASSIS AVAILABLE: While 2 and 4 port CAN port are fanless by default, also 8 port CAN device can be built into fanless aluminum chassis with IP50 degree of protection for worry-free CAN acquisition in harsh, dusty environments.
  • OBDII AND J1939 SUPPORT: All CAN interface have OBDII and J1939 standard support.
  • FLEXRAY and XCP/CCP: Additional automotive protocols XCP/CCP are supported as well with the included Dewesoft X Professional data acquisition software. FlexRay interface is available using third-party hardware.
  • CAN OUT: All devices can output CAN messages.
  • DBC FILE SUPPORT: Included Dewesoft X software enables easy read of DBC files which will automatically set CAN channels.
  • SOFTWARE INCLUDED WITH FREE LIFETIME UPGRADES: Easy to use, yet very robust in functionality, award-winning DEWESoft X3 software is included. The software comes with lifetime free upgrades and no hidden costs, bringing you intuitive configuration, smart sensors, advanced storage and analysis capabilities.

Reliable CAN acquisition

All CAN interface support transmitting and receiving CAN 2.0b data at full speed of 1 Mbit/s per each channel. All CAN channels are isolated for worry-free CAN acquisition in noisy environments and for maximum signal quality.

CAN devices with 2, 4 and 8 CAN ports are available. Multiple CAN devices can be synchronized together to increase CAN ports.

Data acquisition systems like DEWE-43, MINITAURs, and SIRIUS also offer dedicated CAN bus ports. These ports offer the same CAN functionality as the dedicated CAN devices described on this page.


All configured CAN channels are perfectly synchronized down to microseconds with any other analog, digital, video, etc. data sources. Even if the sampling rates between different data sources are completely different.

CAN devices come with built-in synchronization port which allows for hardware synchronization with other DEWESoft DAQ instruments like SIRIUSKRYPTON or DEWE-43.

Can recording and analysis

With included Dewesoft X Software our CAN interfaces are perfect data recorders for in-vehicle measurements. Software offers:

  • advanced CAN recording, storing and analysis,
  • online monitoring and decoding of CAN messages,
  • offline CAN message decoding,
  • visual display for displaying CAN data,
  • online and offline math analysis of CAN channels
  • CAN DBC file import and export
  • OBDII on CAN, J1939 and XCP/CCP support
  • CAN transmit

Dewesoft X makes it extremely easy to setup CAN channels. The software can read and import CAN DBC or XML files. DBC files are common files for CAN message and channel definition. After the import software will automatically set up all available CAN channels and decode CAN messages.

OBD II, J1939 and XCP/CCP protocols

Dewesoft CAN devices also offer OBD II, J1939, XCP and CCP protocol support. 

OBDII functionality provides real-time data acquisition of wide range vehicle parameters available over vehicle standard OBD II port. It only supports OBD II over CAN which is mandatory on all new cars developed after 2008.

Data acquisition from Electronic Control Units (ECUs) supporting CCP or XCP protocol (over CAN or Ethernet) is also possible with no additional hardware.

Rugged CAN

We offer two versions of CAN instruments intended for CAN acquisition and analysis in very harsh environments.


This 8-port CAN device is built in fanless chassis and therefore no air is flowing through it. It is perfectly suited for more dusty environments.


This is an even more rugged version of 8-port CAN device. This unit is completely sealed and offers the IP67 degree of environmental protection, which means the unit is dust, shock, and water-proof.

Data Acquisition Software Included for Free

All Dewesoft data acquisition systems are bundled with award-winning Dewesoft X Professional DAQ software. Dewesoft X is the world's most advanced and easy-to-use data acquisition and analysis software. Dewesoft X's flexibility and power will help you unleash the DAQ system to its full potentials and gives you many advantages over other DAQ systems. Functionalities like plug-and-play, hardware auto-detection, smart TEDS sensors, advanced storing and data analysis features will take your measurement and analysis needs to a whole new level.


Plug and Play

Connecting the DAQ system and sensors could not be faster or easier. DEWESoft X will automatically detect the connected DAQ systems and TEDS equipped sensors and will configure the entire channel configuration for you. Features like:

  • hardware auto-detection,
  • smart sensors,
  • sensor database,
  • advanced TEDS support,
  • automatic unit conversion,
  • real-time signal preview,
  • store setup files

will make you ready for measurement in seconds. Spend less time configuring your DAQ systems and be more productive. Time is money!

Measure and Store

Powerful storing capabilities with more than 500 MB/s sustained stream rates means you can always store data at full speed and never again worry about losing data that could compromise your tests. DEWESoft X features:

  • real-time data acquisition,
  • synchronized acquisition of analogue, counter, video, GPS, CAN bus, and many other sources,
  • advanced triggering and alarms,
  • single or multi-file storage,
  • remote and distributed network storing,
  • automated test sequences.

Even if you store gigabytes of data, our innovative data file format will ensure you can load and analyze your data as fast as a blink of an eye.

Analyse and Publish

From Vehicle Dynamics, NVH to Power analysis and much more. Forget about using several and complex software solutions just to analyze and visualize your data. DEWESoft X offers advanced data visualization, analysis, and reporting tools:

  • online and offline mathematics,
  • flexible real-time visual displays,
  • synchronized video support,
