System Background:


The Entrance Module TV works much like your TV at home. But instead of a cable box we are using an Entrance Module Computer (Kangaroo Computer) to send a signal via an HDMI cable to the TV. When the Entrance Module Computer is working properly it should send a signal to the TV, however occasionally this computer needs to be reset, much like your computer at home.
