Description

The plug & play 2x CAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD card.

It's easy-to-use: Simply connect the device to your CAN bus to start logging raw CAN data. Next, extract the data and process it using 100% free open source software/API tools - incl. file format conversion, DBC decoding and plot visualization.

Ideal for recording CAN/LIN data over weeks, months or years - e.g. for diagnostics, OEM development or legal/warranty purposes.

Pro specs CAN logger

The CANedge1 combines innovative design, cutting-edge components - and incredibly low costs:

• 2 x CAN (incl. CAN FD) + 2 x LIN channels
• Extractable 8-32 GB industrial SD card (= months of data)
• Popular binary MDF4 log file format
• Advanced message filtering & transmit functionality
• Route data from CAN1/2, LIN1/2 onto CAN1/2
• Start/stop logging triggers based on CAN ID & databytes
• Silent mode, bit rate auto-detection, cyclic logging
• Data compression & encryption (e.g. for GDPR, CCPA)
• Support for CAN/LIN error frame logging
• Fast boot time. Safely disconnect during use (power safe)
• Add CANmod to e.g. log 5 x CAN or temperature/analog data

The device includes an extractable 8-32 GB industrial SD card (Class 10). This ensures e.g. optimal endurance and rapid data transfer (W/R 50/80 MB/s)

The CANedge enables logging of raw CAN/LIN data incl. CAN FD, J1939, CANopen, OBD2, UDS, ISOBUS, NMEA2000 - across any CAN/LIN application.

The device is designed to be extremely compact (75 x 47 x 20 mm). Despite the robust aluminium enclosure, it weighs only 100G.

The 2x high speed CAN channels enable time-synced recording of data from two CAN buses - ideal for e.g. many heavy duty vehicle applications

The 2nd port (CH2) provides a configurable 5V power out, letting you easily power e.g. CANmod sensor-to-CAN modules (temperature, analog/digital/pulse, ...)

The CANmod.router module can e.g. be used as a plug & play add-on for the CANedge (powered via 2nd port) - letting you log 1 x CAN (via CH1) + 4 x CAN (via CH2)

The CANedge1 comes with flanges to enable easy installation at scale. The 'mounting kit' includes screws and optional vibration dampeners.

Note: If you need to remotely collect data via WiFi or 4G LTE check out the CANedge2 or CANedge3.

Vehicle blackbox / Event Data Recorder (EDR)

Need to monitor data from your vehicle fleet?

The CANedge1 is ideal for recording data over long periods from fleets - incl. cars (via OBD2) and heavy-duty vehicles (via J1939). With filters, compression, data encryption and cyclic logging you can safely log the latest months or years of data. This makes the device well-suited as an automotive data logger for e.g. warranty/legal data storage or optimization. The CANedge1 can also serve as a low cost Event Data Recorder (EDR) for e.g. UN R169 requirements.

Rare issue identification

Need to identify a rare, but critical issue?

If you have e.g. production equipment that periodically exhibts an issue the CANedge1 is a great diagnostics tool. Simply connect it and leave it in, creating a rolling window of e.g. the last X months of data. If the issue occurs, you can extract the raw data, DBC decode it and plot it for quick diagnostics.
 

Equipment development & optimization

Need to optimize your CAN based equipment based on long-term data?

The standalone CANedge1 is ideal for recording data from equipment deployed in the field: It is durable, compact and simple to install. You can e.g. pre-configure the device - and ship it to the end-users for installation.
