CSS Electronics - CL2000: CAN Bus Logger (+RTC)

The plug & play CL2000 CAN logger records CAN bus data to an 8 GB SD card and timestamps it with a real-time clock.

Further, the CL2000 can operate as a CAN bus interface for real-time USB streaming.

The CAN logger is ideal for vehicle fleet management (trucks, buses, harvesters, cars, ...), prototype field testing, diagnostics or reverse engineering.

  • 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

 

Convert & DBC decode log files

The CL2000 also comes with software tools for converting & decoding log files

Compact CAN logger with SD

  • 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

Use Cases

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.

 

Note: We recommend that you also check out the 2nd generation CANedge1 or CANedge2 with WiFi.

 

 

Vehicle development & field testing

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.

 

 

Rare issue identification

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.

 

 

Compliance monitoring

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 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

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.
