    Note: In order to use LabQuest with Logger Pro or Graphical Analysis, you will need to disable the “Enable Viewer over USB” option on your LabQuest 2 or LabQuest 3.

*LabQuest Viewer uses network device discovery to find LabQuest devices on your network. Changes to your device’s network settings will reset the discovery process. This can take several minutes to regenerate the list of available devices. If connection issues persist, check with your network administrator to ensure your network supports multicast device discovery.
