1. You must upgrade the DTX5000-CTL to 2.2.0.5532 code before using these files.
2. Once code is at 2.2, you may upgrade using the postgres file first. (Failure to do this will result in complete unit Failure!!) Use standard upgrade procedure!
3. Then use the 4.0 file to upgrade the application.
4. If you have Beta firmware at 3.X you do not need to install the Postgres file first.
5. If in any Doubt contact mark.hempel@black-box.de before the upgrade.
