Yep; see here for a diagram for two cascaded SWiM-16s;
And DECA node limit is 16. Beyond that the "Unified PlayList" (UPL) on each receiver will not display all other connected receivers.
which ones would they show? could they be two sepreate systems just the samd odu? if i could use this on bigger buildings this could help alot with the old one dish per building my company will never buy anything bigger than a 16 unless its a mdu with at least 100 units.... thnaks guys!
