CAN Bus Data

Dewesoft X can interface with all Dewesoft CAN and CAN FD devices which are a dominated vehicle bus interfaces found in today's vehicles. Dewesoft X can decode any kind of data from the CAN bus in read-only or acknowledge mode. Support for OBDII on CAN, J1939, and J1587 standards is also available.

Dewesoft X makes it extremely easy to setup CAN channels. The software can import and export 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.

Dewesoft X can interface with our CAN FD devices to read, store, and analyze the CAN FD data from the vehicle CAN bus. 

Key features

  • Synchronized CAN FD acquisition with other sources like analog, digital, video, GPS, etc.
  • Decode, store and send CAN FD messages
  • Dual baud rate up to 12 MBit/sec
  • Message decoding up to 64 bytes
  • Support for CAN DBC or XML file import and export for easy setup of CAN FD channels

Dewesoft X offers support for XCP and CCP protocols via XCP/CCP plugins.

The plugin enables data acquisition from Electronic Control Units (ECUs) supporting CCP or XCP over CAN or Ethernet protocol. It supports multiple ECU's. No additional HW is needed except CAN or Ethernet port. 

For more information see:

XCP Devices

Next to XCP Slave and Master plugins, Dewesoft also introduced SIRIUS XHS and IOLITE LX devices which can natively serve data via XCP on Ethernet without the need of any software. You can watch a short presentation video.


FlexRay is an automotive network communications protocol developed by the FlexRay Consortium to govern on-board automotive computing. It is designed to be faster and more reliable than CAN.

Dewsoft X data acquisition software offers support for FlexRay protocol with the FIBEX library import option. All Vector FlexRay cards are supported.

LIN bus 

The LIN bus plugin allows you to simply connect and listen to communication on multiple LIN networks. Using Vector hardware, it mimics listen-only slaves that listen to all data transmission on the bus. Decoding can be done in three different forms:

  • analog data with extensive scaling options,
  • discrete data
  • a mix of both.

The plugin supports importing the configuration from LIN description files (LDF). To read the LIN bus, a Vector LIN card is required.

SENT (SAE J2716)

The SENT protocol (Single Edge Nibble Transmission - SAE J2716) is a data transmission protocol that has seen a big increase in use, especially in the automotive industry. The module developed decodes a SENT signal transmitted from a sensor using counter channels.

The module supports two fast channels and any number of slow channels, which are detected automatically. The SENT signals can be decoded from multiple sensors simultaneously while each sensor is using a dedicated counter channel.

Reliable CAN Bus Acquisition and Analysis

All CAN interface support transmitting and receiving CAN 2.0b data at a 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.

CAN FD Analyzer

The bandwidth requirement of new automotive applications is rapidly increasing. Automotive OEMs are thus introducing CAN FD in new cars. CAN FD can provide significantly increased bandwidth due to increased data clock rates, and to larger data payloads. CAN-FD is used with an increase in the number of sensors inside the vehicle and is much faster than the normal CAN2.0 - which is limited to 1Mbps.

KRYPTONi-1xCAN-FD is a single port CAN FD device that uses EtherCAT as a data interface. It supports high-speed CAN interface with data rates up to 8 Mbps. Besides this, CAN FD also supports the CAN2.0 communication protocol as well as special protocols such as J1939, where CAN out is used as read-only.

The new KRYPTONi-1xCAN-FD uses galvanically isolated communication lines and an isolated sensor supply of +5 V and +12 V. Power limit for the sensor supply is 1.4 W.

This product is the latest member of the award-winning KRYPTON ONE product line. A line designed for extreme conditions with an operating temperature range between -40°C and +85 °C and IP67 rating.

KRYPTONi-1xCAN-FD is supplied in a standard KRYPTON ONE chassis with a DSUB9 input connector.

Rugged CAN Bus Analyzer

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

Fanless IP50 SIRIUSif-8xCAN

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.

Waterproof IP67 SIRIUSiw-8xCAN

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.
