18. Logging with a Memorator

This section shows how to extract a log file captured by a Kvaser Memorator and how to convert the log into a format suitable for playback in CANtrace.

The method shown should work with any Kvaser Memorator interface/logger and requires that the Kvaser Memorator Config Tools software is installed.

18.1 Extract and Convert the Log File

Please connect the Memorator with a USB cable to your computer before continuing with this tutorial.

There are two different options for starting the “Kvaser Memorator Config Tool”:

Option 1: From the Windows Start menu, in this example it is called “Kvaser Memorator Pro 5xHS” .

Figure18.1 Start menu

Options 2: Start the tool from the Kvaser Device Guide tool .
In the tree view, right-click on Hardware > Kvaser Memorator and Select Configure Memorator .
