St Model TIE24-8 & Model TIE12-8
Engineered for Inter-Studio Tie Lines
General
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. 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.
DC Power
DC Tie-Line hub models allow St DC-Link +/-
15 volt power to be added on the far-side of the link to power
local StudioHub powered peripherals (such as headphone
amps and MatchJacks). An external St DC power
supply must be utilized. Jumpers and re-settable fuses for each
RJ-45 channel allow the DC power to be added. The power
option is only available on 2-pair per RJ-45 Hub models.
Grounding Information
RJ-45 connector shields may be optionally connected to the
chassis ground by inserting a jumper. A jumper is also
provided to allow the unused CAT-5 25
th
pair to be
connected to this common shield bus. In addition, on
powered models, the power supply shield may be jumper
connected to the RJ-45 shields.
