a
Power connector — Plug the included external 12 VDC power
supply into this 2-pole captive screw connector. See "Power
supply wiring", on page 12, to wire the connector.
b
A/V Input connector — Connect one end of the cable carrying
the video and audio or serial TP link from the transmitting
device, to this RJ-45 female connector.
See "TP cable termination", on page 13, to wire the RJ-45
connectors.
c
A/V Output connector — Connect one end of up to four or eight
TP cables to these RJ-45 female connectors.
Connect the free ends of the same cables, carrying the
distributed video and audio or serial TP link, to the RJ-45
connectors on the receivers.
See "TP cable termination", on page 13, to wire the RJ-45
connectors.
N
The MTP DA’s output does not provide any pre-peaking
control. The total recommended distance for a complex
system with multiple DA outputs is the same as for a
simple system with a single transmitter and receiver.
N
See the recommended transmission ranges in the table on
page 3. The table’s recommendations apply to a complete
transmission system, which can include a single
transmitter, DA, and multiple receivers or a complex
system including multiple daisy-chained receivers.
d
Output Mute connections — The Output Mute connector
provides a way to mute (blank) any or all TP outputs. Each
numbered pin of the captive screw connector is assigned to
one of the DA’s outputs (pin A is assigned to all DA outputs)
(gure 7). When you short and latch a numbered pin or pins to
ground, the DA mutes the associated output(s).
