c Audio connector — If desired, plug an analog audio input into the transmitter via 
this stereo mini jack connector.
NOTES:  • The analog audio input on this connector is in addition to the digital audio 
that is embedded in the DVI input.
• See the figure at right to identify the tip, ring, 
and sleeve when you are making connections 
for the transmitter from existing audio cables. 
A mono audio connector consists of the tip

d  RS-232 and IR connector — Connect a serial RS-232 signal, a modulated IR signal, 
or both to this 3.5 mm, 5-pole captive screw connector for bidirectional RS-232 and IR 
communication. See “RS-232 and IR connector wiring“ to wire the connector.
e DTP and Analog Audio Output RJ-45 connectors — Connect one end of one 
(or two) TP cables to these RJ-45 female connectors on the transmitter.
CAUTION:  Do not connect this device to a computer data or telecommunications 
network.
NOTE:  See “TP cable termination“ to properly wire the RJ-45 connectors and for 
detailed NOTES.
à DTP Output connector (Required) — Ensure the free end of this cable is 
connected to the receiver DTP In connector (item 
å
). This cable carries:
•  TMDS (digital) video
•  Embedded audio (if any)
•  Bidirectional RS-232 and IR commands and data
•  Remote power
Signal LED — This LED lights when the unit is receiving a TMDS clock signal on 
the DVI input (transmitter) or any valid signal on the DTP In connector (receiver).
Link LED — This LED lights when a valid link is established between the units on 
the DTP input and output cable.
â Analog Audio Output connector (Optional) — If desired, ensure the free 
end of this cable is connected to the receiver Analog Audio In connector (item 
ç
). 
This cable carries analog audio only and is not needed for applications that do not 
require this audio signal.
f Power input connector — Plug the included external 12 VDC power supply into 
either this 2-pole connector or the power input connector on the receiver (item 
k
). See 
“Power supply wiring“ to wire the connector.
NOTE:  One power supply can power both units. A power supply is included with 
the transmitter.
