Video Wall Signal input

There are three ways to get a signal into the Video Wall

Using the video splitter module "Datapath" (DVI, connected to the Graphics Workstation "Ariadne" on the right side of the right table)
Using the "Daisychain" input (Displayport, connected to Sound Workstation "Enigma" on the left side of the right table)
Using the RasPis (Distributed on the back of the wall

The Signal from the videosplitter box and the Pis share a single input of the screens using an HDMI switches.

The HDMI-switches need to be powered by the Pis in order to work! (Neither the Splitted Signal from the "Datapath" Box nor the Pis will work if thex are not)
