5 Connecting the TP-125/TP-126 Transmitter/Receiver Pair
You can use the TP-125 UXGA / Audio / Data Line Transmitter and the
TP-126 UXGA / Audio / Data Line Receiver to configure a twisted pair
transmitter and receiver system, to transmit the video, audio and RS-232 control
signals via CAT 5 UTP cable.
To connect the TP-125 and the TP-126 to create a twisted pair transmitter and
receiver system, as the example in Figure 5 illustrates, do the following:
1. On the TP-125, connect:
An UXGA source (for example, the graphics card on a laptop) to
the UXGA IN 15-pin HD (F) connector and an audio source to
the Audio IN 3.5mm mini jack, for example, using a Kramer
C-GMA/GMA cable (VGA 15-pin HD (M) +Audio jack to VGA
15-pin HD (M) +Audio jack)

An RS-232 cable with a 9-pin D-sub connector at one end to the
laptop, and a 3 PIN terminal block connector at the other end to
the TP-125 RS-232 port

2. On the TP-126, connect:
The UXGA OUT 15-pin HD (F) connector to the AV display
system
The S/PDIF Audio OUT RCA connector to a digital AV
Receiver (leave the ANALOG Audio OUT 3.5mm mini jack
unconnected)
An RS-232 cable with a 3 PIN terminal block connector at one
end to the TP-126 RS-232 port
3
, and a 9-PIN D-SUB connector
at the other end to the RS-232 port on the AV display system
3. Connect the Line OUT RJ-45 connector on the TP-125 to the LINE IN
RJ-45 connector on the TP-126, via UTP cabling
4
(with a range of more
than 300ft (>100m)).
4. Connect the 12V DC power supply to the power socket and connect the
adapter to the mains electricity on both the TP-125 and the TP-126.
5. On the TP-126:
Adjust the video output signal level and/or cable compensation
equalization level with a screwdriver, if required
1 By default, both switches are set down (for a negative V SYNC and H SYNC polarity)
2 Not supplied. The full list of Kramer cables is on our Web site at http://www.kramerelectronics.com. Alternati vely, you can
connect an UXGA source to the UX GA IN 15-pin HD (F) connector, and a separate audio source to the AUDIO IN 3.5mm
mini jack
