  • 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 superior 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.

Convert & DBC decode log files

The CL1000 also comes with software tools for converting & decoding log files

  • Convert log files to Vector ASC or PEAK TRC
  • Decode log files with DBC support in SavvyCAN
  • Export output as CSV for e.g. Excel pivots

The CL1000 is suited for short-duration standalone data logging and ad hoc data streaming.

Below we outline some of the typical applications for the CL1000 - also, check our case studies for real customer use cases.

Note: We recommend that you also check out the 2nd generation CANedge.

Reverse Engineering CAN Bus Data Wireshark

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, real-time 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.

Compliance monitoring

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 CL1000 is a simple low cost solution: With an 8-32 GB SD and cyclical logging you can log all the CAN, OBD2, FMS or J1939 data you need - and collect it on a case-by-case basis.

Vehicle Fleet Field Testing CAN Bus Data

Vehicle development & field testing

Need to develop, debug or optimize your vehicles?

The CL1000 provides OEM teams with an easy tool for collecting vehicle data. In particular, the CL1000 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.

See the docs section for the CLX000 intro, manual, firmware & software downloads.

The 8GB SD card provides significant capacity. 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 CLX000 series 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, the CLX000 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.

The CLX000 series can be powered via the CAN bus. This means that you simply connnect the device via the DB9 connector to power it. In cars, you'll typically need a DB9-OBD2 adaptor, while for e.g. trucks you may use a DB9-J1939 adaptor.

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.
