This module was part of the rack box project — which was terminated when I moved out of my first apartment.
Status panel


The Rack status panel shows signals from almost every module in the Rack box. Located on my desk it gives a good overview of the system. The panel also has switches and buttons that makes it possible to reset alarms, control lights, fan, mute etc. The panel has a total of 60 drilled holes for buttons and LEDs and 71 connection point, from three D-Sub contactors. The module Digital emergency interface module is housed inside the status panel.
