I also have to add that the diagram is also wrong in terms of what port is what... the have the ports to LNBs and receivers backwards (left to right) as well as where port 1 is relative to the ground screw (up to down)... READ THE STICKER/LABEL and not that HORRIBLE diagram!!!
That STUPID HORRIBLE dyslexic diagram has screw many a many installers... ROTFL
PS I guess back in the factory in China the decided to orientate the stickers/labels upside down/right side up on different revisions? It's weird as they seem to want the heat to rise up in a certain orientation that if stickered like that diagram would be backwards... STRANGE
