CANvas is our 100% free supporting software tool for the CLX000 series of CAN bus data loggers.

For a quick intro, check out our 4 minute video above!

CANvas provides a full suite of powerful features - below you can learn more about configuration, live streaming and conversion.

The CLX000 is plug-and-play so you can log data out of the box. However, it is also highly configurable - and CANvas is a great tool for doing so!


  • General: Logger ID, separators, file/time split limit (e.g. new log every 50 MB)
  • Bit rate incl. optional auto-detection and Silent/'Listen Only' mode
  • RTC: Customizable RTC and date/timestamp format (CL2000/3000)
  • Cyclic Logging: Delete oldest files when SD card is full
  • Heartbeat: Receive status message every second from the logger
  • Control: Optionally use custom trigger CAN ID to turn logging on/off
  • Transmit: Add custom CAN messages to be sent periodically (e.g. for OBD2)
  • Filtering: Specify message filters & down-sampling to focus your logging
  • WiFi: For the CL3000, you can easily configure the WiFi settings
  • OBD2 DB: Easily log OBD2 parameters with the built-in database
  • WiFi TimeSync: Keep your CL3000 RTCs in sync via online clock
  • Virtual SD cap: Set a virtual max size on the logger's SD card


As a new feature, the CLX000 is no longer “just” a data logger. It now also serves as a fully functional CAN interface - which means you can live stream CAN bus data directly on your PC. With CANvas, it takes just 2 clicks to start streaming!

Via CANvas, you can stream data through the World’s most popular network analyzer, Wireshark. Further, our free open source plugin for Wireshark adds a number of critical CAN bus features.


  • Advanced and highly customizable message/data filtering
  • DBC support: Stream human-readable data (aka engineering values)
  • OBD2 dissector: Convert all Mode 01 standard parameters in real-time
  • 'CAN Live': Trace unique CAN IDs and colorize data changes (for CAN sniffing)
  • Plots: Intuitive real-time graphical plots of converted data (e.g. OBD2, J1939, …)
  • Easily export to multiple formats incl. *.csv, *.c, *.txt and more
  • Load a CLX000 log file to leverage the Wireshark & Plugin features
  • Connect to the logger while data logging and leverage all the above features


Finally, CANvas supports easy conversion of your CLX000 log files!

Simply load a DBC file, your log files and convert the data to scaled engineering values. The output format is *.csv, ready for import into e.g. Excel or other 3rd party software.


  • Load DBC files: Convert via the standard DBC format (incl. J1939)
  • FMS: Built-in support for FMS conversion rules (buses, trucks)
  • Batch convert: Load batches of log files & link them based on session IDs
  • Rules: Add custom conversion rules (incl. name, start bit, length, scale, offset)
  • Downsampling: Downsample the logged data to e.g. 5 min interval output
  • Columns: Add custom columns to the output file
  • Timestamps: Adjust timestamps to e.g. be split in columns (Excel pivot friendly)
  • Merge log files: Merge multiple files into one output file
  • Re-format log files: Change format into Vector CANalyzer or PEAK formats
  • Summary Stats: Add summary statistics to downsampled data (std. dev., min, max)
  • OBD2: Easily convert OBD2 data with built-in conversion rules
  • Auto-convert: Set up scheduled auto conversion in seconds
