I dunno.
The guy told me that he got it from Nelson, and I would have expected that everything needed would have been with it.
The exhibit was from the maker of the speaker system, so I don't think that anything would have been left out internally, or externally, because he was making the stuff, and he sounded from his conversation to know Nelson Pass.
But, to answer your question directly, I don't know for sure if there was any network used or not.
