2.1  
Achieving the Best Performance  
To achieve the best performance:  
Use only good quality connection cables to avoid interference, deterioration  
in signal quality due to poor matching, and elevated noise levels (often  
associated with low quality cables)  
Avoid interference from neighboring electrical appliances that may adversely  
influence signal quality  
Position your Kramer TP-122N away from moisture, excessive sunlight and  
dust  
Caution:  
No operator serviceable parts inside the unit  
!
Warning: Use only the Kramer Electronics input power wall  
adapter that is provided with the unit  
Warning: Disconnect the power and unplug the unit from the wall  
before installing

Overview  
The Kramer TP-122N is an XGA/audio line receiver that receives the coded CAT 5  
signal transmitted by a TP-121EDID XGA / Audio Line Transmitter, for example,  
decodes it and converts it to XGA, stereo analog and S/PDIF digital audio outputs.  
The TP-122N, with the TP-121EDID transmitter, allows an operation range of more  
than 300ft (more than 100m) over standard CAT 5 cable.  
The TP-122N:  
Is HDTV Compatible  
Has a maximum resolution of WUXGA and 1080p  
Includes EQ. and level controls  
Can power or be powered by the transmitter over the same CAT 5 cable  
when the devices are within 50m (150ft) of each other  
Is 12V DC fed  
The TP-122N is housed in compact TOOLS® enclosure where three units can be  
rack mounted side-by-side in a 1U rack space with the optional RK-3T rack  
adapter.  
3.1  
Shielded Twisted Pair (STP) / Unshielded Twisted Pair  
(UTP)  
We recommend that you use Shielded Twisted Pair (STP) cable, and stress that  
the compliance to electromagnetic interference was tested using STP cable. There  
are different levels of STP cable available, and we advise you to use the best  
quality STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is  
intended for analog signals where skewing is not an issue.  
In cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-free  
cable, Kramer BC-XTP, may be advantageous, and UTP cable might also be  
preferable for long range applications. In any event when using UTP cable, it is  
advisable to ensure that the cable is installed far away from electric cables, motors  
and so on, which are prone to create electrical interference.

3.2  
About the Power Connect™ Feature  
The Power Connect feature applies as long as the cable can carry power. This  
feature is available when using STP cable and the distance does not exceed 50m  
on standard CAT 5 cable. For longer distances, heavy gauge cable should be used  
(CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the  
power at these distances). For units which are connected via RJ-45 connectors,  
make sure that the shield of the STP cable is connected to the metal casing of the  
connectors on both ends of the cable. For units which are connected via terminal  
block connectors, the shield of the STP cable must be connected to a ground  
terminal on the units at both ends (use the ground terminal of the power supply  
connection if necessary).  
For a CAT 5 cable exceeding a distance of 50m, separate power supplies should  
be connected to the transmitter and to the receiver simultaneously.

Connecting the TP-122N XGA/Audio Line  
Receiver  
You can use the TP-121EDID and TP-122N to configure an XGA/Audio Line-  
to-Twisted Pair Transmitter and Receiver system.  
To connect the TP-121EDID XGA/Audio Line Transmitter with the TP-122N  
XGA/Audio Line Receiver, as the example in Figure 2 illustrates, do the following:  
1. On the TP-121EDID, connect the XGA source (for example, a laptop’s  
graphics card) to the XGA INPUT 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).  
2. On the TP-122N, connect the XGA OUT 15-pin HD (F) connector to the  
XGA acceptor (for example, a display), and connect the AUDIO OUT S/PDIF  
RCA connector to the digital audio acceptor (for example, an AV Receiver),  
and the ANALOG 3.5mm mini jack to the analog audio acceptor (for  
example, a stereo audio recorder).  
3. Connect the LINE OUTPUT RJ-45 connector on the TP-121EDID to the  
LINE IN RJ-45 connector on the TP-122N, via UTP cabling (with a range of  
more than 300ft (>100m)), see Section 4.1.  
4. Connect the 12V DC power adapter to the power socket and connect the  
adapter to the mains electricity on both the TP-121EDID and the TP-122N.  
The signal from the XGA source is transmitted via CAT 5 cable, decoded  
and converted at the XGA OUT 15-pin HD (F) connector to the XGA  
acceptor.  
If you cannot connect the power to both the TP-121EDID and TP-122N, you can just  
connect the power to the TP-122N  
5. On the TP-122N adjust the video output signal level and/or cable  
compensation equalization level, if required.  
Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level
