Import and Export

This section contains details about the import and export options.

Import

  • Tuning Data: Use this option to import an existing tuning file (*.set or *.setr).
    Users can use the following hints to see if the “imported tuning file” has made any changes to the device:
  • Check the State Variable Explorer to see if the values of the corresponding state variables have changed.
  • If the device and GTT are in sync, sending tuning data should cause the frequency response to change.
  • The user can manually create a set columns to obtain the current state of the state variables after importing the tuning data file on the device.
  • The user can use the set column that is already present after importing the tuning data file on the device and pressing the “store” button. If the set column in the set file contains state variables, the user can view the modifications.

Export

  • Tuning Data: Use this option to export a tuning file (*.set or *.setr).
    While exporting the tuning file, a dialog box will appear, select the folder where the files (.set/.setr) will be stored.

This method creates a .set file which contains all the object tuning data, that includes all of the device’s state variables. For example, if certain objects are not tuned, their default tuning values will be exported to the set file.

  • Export DDF Data: Use this option to export a device description data file (*.ddf ).
  • Export Control Pin Data: Use this option to export Control Pin Data (*.csv).

In the Default Control Pin export, the Core Id and Instance Id fields have been removed and will no longer be used.

If no configured control pin data is available, it shows the message “Control pin not configured for device”.

  • Device Template: Use this option to save the device template file  (*.flash).

Important

The Device File option is hidden by default.

Steps to make the Device File option visible under in Import/Export option:

1. Go to the GTT installation path and locate GlobalTuningTool.exe.Config file.

Location: C: Program FilesHarmanHarmanAudioworXtoolsGTT

2. Open the file in any text editor (Notepad) and update “AudioObjectDeveloperMode” attribute under “appSettings” node as shown below.

3. Set Value = true to enable Device File option. Similarly, set Value = false to disable Device File option.

Restart the GTT to take effect of the updated settings.
