If you are not sure how to connect, follow the steps shown here to connect via USB. Once you are connected, you may proceed with the steps below.

Always backup your settings BEFORE a firmware update!

Before proceeding with a firmware update, we highly recommend you backup your device settings and sensor data. Doing so will ensure that you have a backup of your original settings if you need them. Depending on how large of a firmware jump you are doing, it is possible you may need to use your backup file to restore your original controller settings and probe calibration data.

To backup your controller settings and probe calibration data, click the Backup and restore tab.

  • Select Transmit all settings from ProfiLux to file to create a backup file of your settings.
  • Select Transmit all sensor data from ProfiLux to file to create a backup file of your probe calibration data.

Are you using any VIRTUAL SENSORS? Read this!

If you are using virtual sensors (ProfiLux 3 and higher), make sure you write down the control settings for these sensors as they will not be included as part of the backup settings file. Depending on the extent of the changes in the firmware update, if the ProfiLux is reverted to factory settings, at least you’ll have your virtual sensor info ready to re-enter.
