I have run an extra coax to another room by splitting one of the cables after the isolator. I purchased another V box of ebay which is the same as my existing box. The idea being we can move the viewing card from one box to the other if we want to view in the other room I have placed my viewing card in the recently purchased box but after booting it seems to stick with "AP:52" on the display and the heart symbol flashing. Anybody know what I'm doing wrong? I didnt think the viewing cards were tied to any particular VM box are they?
