Thank you for your reply. 🙂
T112 connects via Dsnake-grade cable to network wall socket at FOH control booth point, permanently installed by building contractors (presumably Cat 6 but uncertain. Reno is only 8 months old).
Comes out socket of same on OP side of stage. However, as part of diagnostic process of elimination I have changed that now to direct from the socket to the IDR 64.
Rack also has 5 dual UR4D SHURE units in the network. Only other network member is Meyer Galileo controller unit. That’s mostly it.
Fairly simple set up.
