I have a 211 in my daughter's bedroom. I want to move it to my deck TV that is currently the TV2 from my 722. I want to use TV2 from my 722 to now run in my daughter's room. I assume there needs to be some cables moved on the main junction box on the side of my house. To avoid paying for a tech visit (and wasting their time for what would probably be a 5 min procedure) is there a device that can plug into the outlet that identifies the outlet to the cable outside? If not I could always get an EHD for the 211.
