Locked Setups
Overview
Setups may be saved to files that are locked from editing and may only be programmed to displays. Locked setups include thumbnails of screens for preview purposes.
Exporting Locked Setups
To export a locked setup, use the command.
Locked setups may be loaded into Dash Design and programmed with F7.
Locked setups have the file extension .gddp.
Some Display Modules support serial number locked setups. If supported by the display, check the Lock to Serial Number? box and enter in the display serial number.
Locked setups may have the original source setup file name included in the file. If desired, check the Embed Setup File Name box. The file name may be edited to remove any user information or it could be changed to a URL.
The original setup file may also be embedded in the locked setup file. If desired, check the Embed Source Setup File box. A password must be specified. The original setup will be LZMA compressed and AES encrypted with a key cryptographically derived from the password and a ‘salt’ value.
If the original setup file is embedded in a locked setup. The original setup file may be extracted from the locked setup file using the File Info tab which is available when the locked setup file is loaded into Dash Design.
File Info Tab
The File Info tab provides information about the locked setup file. The File Info tab is only available when a locked setup file is loaded into Dash Design.
The File Info tab provides the following information:
| Field | Description |
|---|---|
| Setup Binary Checksum | Checksum of the setup binary data, this should match the checksum calculated by the display module when the setup is loaded. |
| Setup Binary SHA-1 | SHA-1 hash of the setup binary data. |
| Source Setup Name | The setup name set on the Setup Name |
| Source Setup File Name | The file name of the source setup (if any) embedded in the locked setup. |
| Source Setup File MD5 | MD5 sum of the setup file that the locked setup was generated from. |
| Source Setup File SHA-1 | SHA-1 hash of the setup file that the locked setup was generated from. |
Setup Binary Checksum may be used for scrutineering purposes to ensure that the setup file loaded into the display module has not been tampered with.
