Record raw data

Below we outline how to record raw data to the device SD card.


Before you connect your device, it is important that you do the following:

  1. Read the introduction and hardware installation guide in the CANedge1 Docs

  2. Verify that the pin-out of your application, adapter cable & CANedge match

Verify that you can log data

  1. Connect & power the CANedge in your application via Channel 1 (green LED lights up)

  2. Verify that the device records data to the SD card (yellow & red LEDs blink)

  3. Disconnect the device, extract the SD and confirm that the LOG/ folder now contains data1

If you’re logging data from cars or heavy-duty vehicles, see our OBD2/J1939 sections. If you’re having trouble logging data, see our troubleshooting section.


Once you’re done testing we recommend that you configure filters, prescalers & compression to reduce your file size (often by 90%+) - see also our tips & tricks section


It is important that you disconnect your device before extracting the SD card to avoid SD card corruption. Similarly, when ejecting the SD card from your PC, make sure to use the ‘safe eject’ functionality
