This might and probably is a noob question, but before I go and set something up I prefer to be safe than sorry with my set up. I am very interested in the iRule set up, and I would require a gateway that then send out an IR signal. Disregarding that, I would like to be able to have one IR wire in the room that will send the signal all over the room and be able to cover all the equipment on my rack and possibly a second one of that sort to cover the projector. My question is, is that what a blaster does? Is there a difference between a blaster and an emitter? I certainly do not want to connect one of those stick IR diodes on my AVR and other equipment. I rather have one emitter that will have a wide spread.
