Frequently Asked Questions
In most settings, CANedge3 will upload data at a rate of approximately 4-7 MB/minute. For most use cases, this is more than sufficient to enable consistent offloading of SD cards.
For example, if you record 2 x CAN from a truck without any size optimization, you will typically generate about 1-3 MB/minute of data. In this case, you can easily offload the log file even if you haven't covered it for a while.
In addition, in more realistic scenarios, you will want to optimize log file sizes with filters, prescalers, compressors and triggers - see also ourguidebookThe optimization of the data is not a good idea. Enabling such optimizations usually results in logging data at speeds close to 0.01-0.05 MB/minute.
Therefore, the main situation where upload speed can be a bottleneck is if you deploy CANedge3 to “log everything” for long periods of time and the device is located outside of the cellular network's coverage area (e.g. on a ship or in a mine). Here you need to check the amount of data accumulated during the period outside the coverage area and the time spent by the device in the coverage area.
The CANedge is the second generation of the CLX000. we generally recommend using the CANedge for data logging use cases, and primarily recommend using the CLX000 if you need to transfer data via USB.
Key improvements of the CANedge over the CLX000 include:
mechanical
- SD can be retrieved:Captures SD and transfers data at 80 MB/s (vs. 0.5 MB/s for CLX000 via USB)
- Industrial SD: CANedge uses an industrial SD card to improve performance, life, temperature range, and more.
- Passage: 2 x CAN/LIN channels with parallel recording 2 x CAN + 2 x LIN
- Aluminum housing:The new housing is as compact as the CLX000, but more rugged and offers the ability to mount flanges.
- Power output:Powering external modules via a second port, such as theGPS to CAN或Temperature to CANModule
- Solid protection: CANedge with enhanced protection against voltage spikes, etc.

- Dashboard：Easily visualize your data in free customizable Grafana dashboards
Data Logging
- No damage: CANedge can record complete bus loads with zero message loss (CLX000 limited to approx. 800-1000 frames/sec)
- Compression:Optional compression reduces file size by up to 80% compared to the CLX000.
- Encryption:The optional encryption feature allows you to encrypt log files on the SD card for added security.
- Advanced Configuration:More advanced filters and transmission lists (e.g., up to 128 filters vs. 8 on the CLX000)
- Accuracy: 20x better RTC resolution (50 microseconds) - with advanced RTC synchronization options
- Startup time:Much faster start-up time than CLX000 (approx. 1 sec. vs. approx. 10 sec.)
- CAN FD: The CANedge supports CAN FD (Flexible Data Rate), making it future-proof.
- Trigger:Control when to start/stop recording/transmission based on customized CAN signal thresholds
- Error frame: CANedge supports CAN/LIN error frame recording.
- LIN slave/master: The CANedge can act as both a LIN slave and a LIN master (publisher).
GNSS/IMU + connection
- GNSS/IMU: CANedge support for optional built-in GNSS/IMU functionality
- WiFi: CANedge2 supports WiFi data transfer to your own cloud/self-rack servers (including OTA updates)
- 3G/4G LTE: CANedge3 supports 3G/4G LTE data transfer to your own cloud/self-rack servers (including OTA updates)
CANedge3 can split files every 10 - 86400 seconds or every 1 - 512 MB. When a new log file is created, it is automatically transferred to your server via 3G/4G LTE. As a result, you get a steady stream of incoming files - and by using AWS Lambda and our Python API, you can automatically process incoming data "near instantly".
We have many users deploying CANedge2/CANedge3 for near real-time uploads, see hereCase Study on Predictive Maintenance of AutomobilesThe data processing tools available to the user are not available to the user. However, in order to use it effectively, a slightly more advanced use of the available data processing tools is required.
However, for most intentions and purposes, we recommend using a medium/large log file size (e.g. 5-20 MB) to avoid an excessive number of log files in the server.
CANedge requires the use of specific industrial SD card models to ensure performance and power security. You can select either an 8 or 32 GB SD card as an option at checkout.
You should not use 3rd party SD cards as they may cause data corruption and other forms of non-functional behavior.
Yes, this version of CANedge includes the GNSS/IMU module. If you install a device with an external GNSS antenna, you can choose to synchronize the recording of GNSS/IMU data with 2 x CAN/LIN data.
GNSS/IMU messages are logged as if the data were broadcast over a CAN bus network recorded by CANedge. To separate it from the CAN/LIN channel, the data is stored in a log file under a separate "internal" pseudo-channel.
For a general introduction to CAN logging with CANedge, please refer to our45-minute webinar(Recap on CANedge1/CANedge2).
Below, we outline the basics of how to get started recording raw CAN data:
- Connect the CAN logger to the CAN bus (optionally with our adapter cable)
- The device boots up, detects the bit rate and starts recording the raw data to the SD card.
- Disconnect the device, extract the SD and insert it into the PC.
- In asammdf GUI/APIetc. to open the original log file for theDBC Decodingand visualization
Next, you canSetting up your own serverand configure CANedge3 to connect to it to automatically upload log files. After connecting the device, it will automatically upload the log files if there are log files on the SD card. After successful upload, the log file will be deleted from the SD card.
Note that you can use the SIM card supplied with your device - or insert your own SIM card.
In addition to the 3G/4G LTE features in CANedge3, theCANedge1Same as CANedge3 100%.
If you need to collect CAN data only rarely and the device is easily accessible physically, then CANedge1 is usually sufficient. However, if you need to collect data frequently and ideally remotely, then the CANedge3 quickly pays for itself. In particular, if you need to collect data across fleets or machines, CANedge3 is more practical and cost-effective.
CANedge3 has the added advantage that you can fully automate data collection and data processing workflows. For example, you can set up automatedPython APIScripts to modify data, perform DBC decoding, such as setting up theRemote Information Processing DashboardThe CANedge3 is also easier to manage in the field. CANedge3 is also easier to manage in the field, as you canCANcloud Remote Information Processing PlatformMonitor status and perform operations such as wireless configuration and firmware updates.
For use cases where a WiFi network is available, we recommend CANedge2. If you need to upload data via 4G LTE (cellular), we recommend CANedge3.
