PHP script to brute force break DSC Control Panel Installer code using Envisalink ethernet module. Should work for Power Series control panels. Adjust parameters in first lines of the file to match your configuration.
Tested on Envisalink 4 and PC 5010. Passcode restored in 5 hours (26 combinations per minute).
USE ON YOUR RISK, make sure scripts exits installer code when finally entered. Otherwise you can BRICK your panel.
