You want to know *which* particular transmitter is plugged into, for example, input 4? Or you want to know that any transmitter is plugged into input 4?
For the latter, the offline extender gets you where you need to go. For the former, I'd imagine you could open an IP connection to the DM frame, and send it an RCON SLOT 19.1.1 EST and then parse the response for the MAC address.? I'm spit balling that command, ?BTW.?
Right, im currently doing that but it only detects that the unit is online. i want to be able to know what input it has been connected to so that no matter if i gets connected to dm input card 7 or 5 or 9 i can dynamically change the analog init value to always send the source to a particular output.
