The part number you provided is not correct but I will assume the description is and we are talking about the microphone array that used the Walta/mini-XGA connector.
The Polycom microphone arrays are connected to the systems and each other via what is called the CLink 2 cable and protocol. The signal leaving the microphone is a digital signal and only other devices that use the CLink 2 are able to use it. This would include Polycom products like the HDX video systems, the RealPresence Group video systems, the SoundStructure and the SoundStation IP group speaker phones. Additionally the HDX Microphone array can connect to other HDX Microphone arrays, either table/desk top or the ceiling microphone arrays up to the maximum supported by that system.
