The purpose of the integrated PC is to be able to attach a Windows operating system to drive the LED in a manor that it attaches to the back of the LED cleanly and aesthetically. The integrated PC ships separately and attaches in place with two “hand-turn” bolts. The profile is the same as the back of the S Series LED so that it fits flush out of site on the rear of the unit. It is powered from the LED itself so only requires one cord to the power outlet.
