DISPLAX Service allows you to save or load all settings and calibration values from one Touch Controller to another of the same model and firmware version. You can also save a settings file as a backup to upload in future.
To achieve this in any of the supported operating systems, follow these steps:
$ displaxservice -a 127.0.0.1 --device-settings download "path-to-save-location"
$ displaxservice -a 127.0.0.1 --device-settings upload "path-to-the-file"
