CAN streaming in SavvyCAN
The CL2000 can stream raw CAN data via USB to your PC for real-time analysis:
- Stream raw CAN data in flexible views (filters, traces, ...)
- Send CAN frames into your CAN bus with real-time control
- Display human-readable form via DBC files (incl. J1939)
- Create real-time plots of decoded signals like speed, RPM, ...
- Highlight bit/byte changes per CAN ID via the 'sniffer view'
- Quickly plot 'hypothesis signals' for reverse engineering
- Load CLX000 log files for post processing analysis
The CLX000 supports USB streaming via both SavvyCAN and Wireshark. You'll find multiple articles on streaming CLX000 CAN data via Wireshark - e.g. our CAN/OBD2 interface, real-time DBC decoding and reverse engineering articles.
Recently, we've added native support for SavvyCAN and we believe it is a super streaming/analysis tool vs. Wireshark - and we therefore recommend to start with that. However, if you have prior experience with Wireshark you can of course still use this for streaming your CAN data.
Free CANvas software
CANvas lets you easily configure your CL2000 and DBC decode logged CAN data to human-readable form.
- Convert log files with DBC & OBD2 support
- Merge log files - or append to an existing output file
- Convert log files to ASC (Vector) or TRC (PEAK) format
- Export output as CSV for e.g. Excel pivots

The CL2000 is ideal for medium to long-term standalone data logging and ad hoc data streaming.
Below we outline some of the typical applications for the CL2000 - also, check our CASES section for real customer use cases.
Vehicle development & field testing
Need to develop, debug or optimize your vehicles?
The CL2000 provides OEM teams with an easy tool for collecting vehicle data. In particular, the CL2000 is useful for late-stage development. Here, the compact standalone functionality means that it can be added to large fleets of prototype vehicles for long-duration logging. After a few weeks or months, the data can be collected and analyzed for optimization and diagnosis.
Use case example: Tribine - Logging a Full Harvest Season of Data
Rare issue identification
Need to identify a an issue that only occurs e.g. every 3 months?
A non-standalone solution is simply not feasible. However, with the CL2000 you can log months of data from one or multiple vehicles or machines at low cost. With cyclical logging, the most recent data is prioritized if no space is left. Once the rare behavior is observed, you'll have all the data you need to troubleshoot it.
Use case example: Cohu - Diagnosing Rare Machine Errors
Need to record and register vehicle data for compliance?
In some scenarios, you'll need to collect compliance or insurance related data - e.g. emissions (e.g. NOx, CO, HC, PM, ...). You may need to legally log this data from your fleet - even if you do not intend to use it actively. In such a setup, the CL2000 is the optimal solution: With an 8-32 GB SD, cyclical logging and RTC you can log all the CAN, OBD2, FMS or J1939 data you need - and collect it on a case-by-case basis.
Reverse engineering proprietary data
Want to reverse engineer proprietary data parameters?
If you're not the vehicle OEM, you may need to reverse engineer certain proprietary CAN data. Maybe you want to hack your car - or maybe you need to add custom functionality in a J1939 test setup. Through data logging, Wireshark streaming and analysis it is possible to identify what CAN IDs relate to what parameters - and how to offset/scale the data. Learn more in our CAN sniffer intro. You can stream data via SavvyCAN or Wireshark, both 100% free and open source.

The CL2000 is an easy-to-use, low cost CAN bus data logger with an 8-32 GB SD card and real-time clock.
What can you use it for? You can use it to record CAN bus data from practically any vehicle (cars, trucks, tractors, ...) and many other CAN applications (machinery, robotics, EV batteries, ...). This includes SAE J1939, OBD2 and CANopen applications.
To get started, simply connect the CL2000 to your application. The device automatically starts recording data to the SD card in a simple CSV style format. This data can then be extracted via USB for post processing.
The CL2000 is compact and stand-alone (no PC needed). Further, you can use our free software CANvas to configure the CL2000 and convert raw data via *.DBC files.
You can also work directly with the CONFIG.INI and log file formats.
Feel free to download a sample of J1939 data from the CL2000 and a J1939 *.DBC sample. You can load both in CANvas to try out the data conversion.
The 8GB SD card provides an enormeous capacity for the CL2000 CAN bus data logger. While space consumption varies depending on your application, 8 GB will provide many weeks worth of continuously logged data. As most vehicles are not running continuously, this typically corresponds to months of data.
If you need to log data for very long durations, you can either upgrade to a 32 GB SD card - or pre-sample your data to a lower frequency (e.g. logging only every 10th or 100th message). Finally, you can add filtering to restrict your logging to certain CAN IDs or J1939 PGNs. For more details on this, see the product manual.
The CL2000 CAN bus analyzers can record data from any high speed CAN bus application (ISO 11898-2). In practice, this includes raw data from almost all vehicles (cars, trucks, tractors, forklifts, buses, motorcycles, ...) - as well as various production machinery, EV batteries and more. Most planes and boats also use CAN bus. In terms of protocols, this encompasses e.g. J1939, CANopen, NMEA, FMS, OBD2 and more.
For the specific case of OBD2 vehicle data, the CL2000 can transmit up to 20 custom CAN messages periodically, which means it can be used as an OBD2 data logger. Note, however, that you need to verify that your car uses CAN as basis for the OBD2 communication (this is the case for all US cars produced after 2008 e.g.). Also, note that all cars differ in the amount of OBD2 parameters they support - and the CLX000 is of course only able to record the supported data.
Once connected, the CLX000 will start recording data - and due to the extremely low power consumption, you can simply leave it in your vehicle. In most vehicles, the CLX000 will power off when the vehicle is powered off. If this is not the case, the power draw of the logger itself is still not an issue in regards to battery drain. However, if you're requesting e.g. OBD2 data in this scenario, the polling may wake up the car's ECUs. In this case, you should avoid leaving the CLX000 powered on in an unused car for more than a few days.
Note that the CLX000 can also be powered via USB when it enters 'mass storage device mode' - this lets you configure the logger on your PC without a separate power source.
The CL2000 CAN bus analyzer includes a real-time clock with battery backup. This means that your CAN bus data will be "timestamped" - i.e. every CAN frame logged on the vehicle network will get a timestamp so that you can link the observed CAN data patterns vs. real-time events.
This is vital in applications where you're comparing your CAN bus data vs. physical events (e.g. weather conditions, time of day, physical interaction with the vehicle, ...). Also, as soon as you're logging data across multiple days, it can be a mess keeping track of your data if you don't have the date and time recorded. In practice, we therefore always recommend to go for a CL2000/CANedge CAN logger if your aim is to primarily log vehicle/machine data, rather than stream it in real-time.
