I know I need an emitter, connecting block and reciever. It seems as if connecting blocks are usually placed near the equipment being controlled. Is it possible to place the connecting block in a central location? Can generic emitters and recievers (eg. xantech) be spliced and terminated on rj45 plugs to run over cat 5? Basically, I just want to plug emitters and recievers into outlets. What is the best way to do this?
