St Model MINITIE12-4 & MINITIE24-4
Engineered for Inter-Studio Tie Lines
General
Mini Tie Hubs provide multi-pair inter-studio connectivity by
splaying out CAT-5 25 pair cable to individual RJ-45
connectors via a 50 pin RJ-21 mass connector. Mini Hubs are
designed to mount and fit where the capacity of full-size hubs
is not needed. Depending on the model selected, either 2 or
4 CAT-5 pairs are connected to each RJ-45 connector.
Double the density is achieved if only 2 pairs (4 wires) are
required to connect to each RJ-45. Generally, 2 pair is
sufficient to support StudioHub analog and digital audio
circuits. All 4 pairs (8 wires) are needed to support KVM and
other special multi-wire equipment circuits.
Mounting
Mini tie-line hubs are available in single units on small wall-
mountable plates, or in double density on 1 r.u. rack mounts
Grounding Information.
RJ-45 connector shields are common on the mini tie hubs.
Two jumpers are provided that allow the unused CAT-5 25
th
pair to be connected to this common shield, as well as to the
hub chassis.
