Frequently Asked Questions
You can chooseCANedge with GNSS/IMU。
In practice, this allows you to synchronize GNSS/IMU data with 2 x CAN/LIN data.
GNSS/IMU signals include position, speed, travel distance, attitude (roll, pitch, heading), altitude, acceleration and more. This data is added to the data log file internally as a "separate CAN channel" - you can configure the inclusion/frequency of each message. For more information, seeCANedge options, including. GNSS/Inertial Measurement Unit (IMU)。
Note: The final results generated by the internal GNSS/IMU are the same as those that will be generated by theCANmod.gpsThe second port connected to the CANedge is essentially the same. However, by building the GNSS/IMU into the CANedge, the overall size and price is dramatically reduced, while enabling simpler installation and configuration. It also frees up the CAN channels on the CANedge.
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
- Captureable SD: Captureable SD to transfer data at 80 MB/s (compared to 0.5 MB/s for CLX000 via USB)
- Industrial SD: CANedge utilizes industrial SD cards for improved performance, life, temperature range, etc.
- Channels: 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 robust and offers mounting flanges.
- Power output: Power external modules, such as GPS to CAN or temperature to CAN modules, via a second port
- Robust Protection: CANedge has enhanced protection against voltage spikes, etc.

- GNSS/IMU: The CANedge supports optional built-in GNSS/IMU functionality.
- WiFi: CANedge2 supports WiFi data transfer to your own cloud/self-rack servers (including OTA updates)
- 4G LTE: CANedge3 supports 4G LTE data transfer to your own cloud/self-rack servers (including OTA updates)
In addition to CANedge2CANedge1 and CANedge2 100% are the same, except for the WiFi function in the CANedge1 and CANedge2 100%.
If you only need to collect CAN data 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 CANedge2 quickly pays for itself. In particular, if you need to collect data across fleets or machines, CANedge2 is more practical and cost-effective.
CANedge2 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 CANedge2 is also easier to manage in the field. CANedge2 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.
CANedge is designed to provide "professional specification" CAN/LIN recorders in the market.Optimal value/cost ratio.
In particular, it is distinguished from similar devices by the following factors:
- Professional specifications: CANedge offers specifications equivalent to the best available recorders.
- Compact: CANedge Smaller than similar devices 50-80%
- Low Cost: The CANedge costs 50-80% less than similar devices.
- Easy to use: the device can be used directly without configuration
- FOSS: All software/API tools are 100% free and open source.
- Interoperable: open standards and tools can be integrated into any system - no lock-in
- Free Support: We offer free, first-class technical support.
In addition, CANedge2 can automatically upload log files to your own server via WiFi:
- SD + WiFi: Automatically upload data via WiFi - and buffer data on SD when WiFi is not available
- Your Server: Retain 100% ownership and control of your data by uploading it to your cloud/self-racking server.
- Security: CANedge2 implements end-to-end enterprise-level security.
These factors make the device an excellent choice for automotive/industrial OEM engineers.
For use cases that require the addition of GNSS/IMU, we recommend the option ofBuilt-in CANedge for GNSS/IMU。
For other sensor inputs (temperature, analog, digital, pulse...) you can connect external sensors to the CAN module to the device. In particular, ourCANmodThe Sensor to CAN module can be easily integrated with the CANedge.
Specifically, the CANedge's second port provides 5V DC voltage to the external module for easy installation. Data from the connected sensor to the CAN module is logged in the CANedge log file along with data from the other CAN/LIN channels.
For example, consider ourCANmod.temp Temperature to CAN module orCANmod.input Analog/digital/pulse to CAN module.
The size of the original MF4 journal file depends on the application and the amount of data you want to record.
The following overview shows a typical example of a heavy-duty truck (J1939 data) with a display speed of 700 frames per second. Obviously, if you record everything, an 8 GB SD card will allow you to record data 24/7 for about 7 days, and 32 GB for about 26 days.
However, CANedge supports powerful options for optimizing the size of log files. Therefore, a more realistic scenario is shown below, where for example a 32 GB SD allows you to log more than 800 days.
Below we have listed some of the key features that will allow you to optimize your journal entries:
- Compression:Enable compression to reduce data size by 50-80%
- Filter:Specify CAN IDs to record/ignore (through range and mask)
- Pre-scaler:Instead of recording frames at their "original" frequency, you can customize the frequency with the CAN ID.
- Control signal:Specify when to start/stop recording based on specific CAN signal thresholds
If the SD is full, cyclic logging allows the CANedge CAN recorder to continue logging data by deleting the oldest log file first.
Compared to the CL2000, the CANedge1 CAN logger is superior at logging data to an SD card. However, CANedge1 does not support real-time streaming over USB. We recommend using the CL2000 for this type of use.
For a general introduction to CAN logging with CANedge, please refer to our45-minute webinar。
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 raw data to the SD card.
- Disconnect the device, extract the SD and insert it into the PC.
- existasammdf GUI/APIetc. to open the original log file for DBC decoding and visualization.
Next, you canSetting up your own serverAnd set CANedge2 to connect to your WiFi to upload log files automatically. 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.
For more details on getting started, see CANedgePresentations and papers- or in case of any doubt.Please contact us.
