If you're in doubt which CAN logger to choose, contact us - we always respond fast with quality sparring.

Below is our 'rule of thumb' guidance:

  • CL1000: If you only need to stream data via USB (or log data without absolute date & time stamping)
  • CL2000: If you need to both stream data via USB and log timestamped data to an SD card
  • CANedge1: If you only need to log timestamped data to an SD card
  • CANedge2: If you need to log data to an SD card and transfer it via a WiFi access point to your own server
  • CANedge3: If you need to log data to an SD card and transfer it via 3G/4G LTE to your own server

Overall, the CANedge (and related software) is far superior for SD logging - and we strongly recommend this, unless you explicitly require USB streaming. If you need to collect data frequently/automatically/remotely, see the CANedge2/CANedge3.

The CANedge series is the 2nd generation of the CLX000 series. The CANedge does not support USB streaming, but is instead far superior for CAN logging use cases.

Below we outline the key advantages vs. the CLX000:

Mechanical

  • Aluminum enclosure: The new enclosure is far more robust and enables use of different external antennas
  • Protection: The CANedge comes with a more rugged protection against e.g. supply transients
  • 5V power out: Easily power e.g. CANmod sensor-to-CAN devices via the 2nd port
  • Channels: 2xCAN/LIN channels, enabling logging from 2 CAN + 2 LIN buses in parallel
  • Industrial SD: The CANedge uses an industrial SD card, improving performance, life time, temperature range & more
  • Extractable SD: The SD can be extracted to transfer data at 80 MB/s (vs 0.5 MB/s for the CLX000 via USB)

Log files & software/API

  • MDF4 log files: Popular binary MDF4 format - more compact than CSV, faster to process, supported by many CAN tools
  • JSON Schema: Config files are based on the JSON Schema concept, supported by many open source tools
  • Config editor: Simple GUI editor lets you easily modify your CANedge configuration online or offline
  • CANcloud: Open source CANcloud browser tool makes it easy to manage log files and e.g. configure devices (incl. OTA)
  • Converters: Open source light-weight converters enable drag & drop/CLI conversion of MDF4 into e.g. *.csv and *.asc
  • asammdf GUI: Enables user-friendly MDF4 log file editing, DBC-conversion (incl. OBD2/J1939), graphical plots & more
  • Python API: Easily process your data at scale and automate the creation of e.g. reports/databases/dashboards

Data logging

  • Lossless: The CANedge can log extreme bus loads with zero message loss (the CLX000 is limited to ~800-1000 frames/sec )
  • Advanced configuration: More advanced filters & transmit lists (e.g. up to 128 filters vs. 8 on CLX000)
  • Advanced triggers: Start/stop logging based on CAN signal values
  • Compression: Optional compression lets you reduce log file size by 50-70%
  • Encryption: Optional encryption lets you encrypt CAN data on the SD card
  • Precision: 20x higher RTC resolution (50 micro seconds) - with WiFi/LTE/CAN/GPS RTC sync
  • Boot time: Much faster boot time vs the CLX000 (~1-2 sec vs. ~10 sec)
  • CAN FD: Supports CAN FD (Flexible Data-Rate) data logging, making it future proof
  • LIN: Supports 2 x LIN bus data logging (publisher or subscriber mode)

WiFi/LTE (CANedge2/CANedge3)

  • WiFi/LTE: Support for automated log file upload via WiFi (CANedge2) or LTE (CANedge3)
  • Over-the-air updates: Update device configuration/firmware over-the-air (OTA) with a few clicks - incl. via batch tools
  • Security: Secure HTTPS transfers. Encrypted credentials on SD
  • Clouds: S3 interface enables plug & play integration in e.g. AWS, Google Cloud, Azure - and free S3 servers like MinIO
  • S3 API: The S3 API enables easy automation of your server file management incl. e.g. OTA updates and log file processing

Internal GNSS/IMU

  • GPS/IMU Optioonally add GPS/IMU for data like position, trip distance, speed, acceleration and more to your data

Further, the CANedge series will be our focus for new firmware upgrades - meaning you'll see a lot of powerful features added in addition to the above over the coming period. The main use case where a CLX000 is optimal is if you primarily need to stream real-time CAN data via USB (which is not supported by the CANedge series).



The CAN loggers are plug & play, letting you record raw CAN data out-the-box:

  • Connect the device to your CAN bus (optionally using one of our DB9 adapter cables)
  • The device powers on, detects the bit rate and starts logging raw data to the SD card
  • Disconnect the device, extract the SD and insert it into your PC (or extract via USB for the CLX000)
  • From here, you can open the raw log files in the free open source software to DBC decode & analyze it

In addition, there are vast configuration options and ways to utilize the software/APIs as part of your CAN data acquisition.

For more details, see the get started guides which go through each step of the CAN logging and data processing.



Below we detail what type of data you can record with our CAN bus systems (split by protocol, application and parameters):

Protocols

All devices can log data from any high-speed CAN bus system (ISO 11898-2) - incl. higher layer protocols.

Examples include:

The CANedge can also log the below:

Applications

The Controller Area Network is used in practically all automotives today and many machinery applications.

Examples include:

Parameters

The devices allow you to log all broadcasted CAN bus data - as well as request e.g. OBD2/DTC data.

Examples include:

  • Speed, Engine RPM, MAF
  • Temperatures (oil, coolant)
  • Throttle & brake position
  • Fuel level & rate
  • Diagnostic trouble codes
  • Tire pressure, ABS
  • Hydraullic pressure
  • Engine torque, exhaust
  • Gear position
  • ... and much more

Note: CAN data acquisition lets you record data in raw form, which means it needs to be decoded to human-readable form (aka 'scaled engineering values' or 'physical values') - so that you can plot and analyze it. This requires a CAN bus decoder software/API/script and a DBC file (database of CAN bus decoding rules).

You can DBC convert CAN data from our devices via the free SavvyCAN tool (CLX000) or the asammdf GUI/API (CANedge). Further, we offer a free OBD2 DBC and a low cost J1939 DBC for conversion purposes.




Our CAN loggers are used in many different use cases - incl. below examples:

Telematics

The CANedge is ideal for telematics in e.g. J1939 heavy duty vehicle fleets or warehouses

Development

For OEMs, CANloggers are core in developing e.g. ECUs and powertrains in test bench setups & dynos

Optimization

CAN bus decoders are key in optimizing fuel costs, driver safety, vehicle emissions, boost performance etc.

Maintenance

Automated access to vehicle data can be a key enabler in both regular, preventive and predictive maintenance

Field tests

Late-stage prototype development requires low cost blackbox vehicle data loggers for field tests

Car diagnostics

CAN loggers can be used to log/stream OBD2 data ideal for e.g. analysis of driving behavior or diagnostics

EV batteries

Data is increasingly critical in managing electric vehicle batteries (EV batteries) - e.g. in forklifts and AGVs

CAN hacking

The CLX000 provides a powerful CAN bus sniffer solution for e.g. car hacking and reverse engineering
