2.1  
Achieving the Best Performance  
To achieve the best performance:  
ï‚·
Use only good quality connection cables (we recommend Kramer high-  
performance, high-resolution cables) to avoid interference, deterioration in  
signal quality due to poor matching, and elevated noise levels (often  
associated with low quality cables)  
ï‚·
ï‚·
Do not secure the cables in tight bundles or roll the slack into tight coils  
Avoid interference from neighboring electrical appliances that may adversely  
influence signal quality  
ï‚·
Position your Kramer products away from moisture, excessive sunlight and  
dust  
This equipment is to be used only inside a building. It may only be  
connected to other equipment that is installed inside a building.

Overview  
The TP-141 and TP-142 are a high-immunity, extended-range twisted pair  
transmitter and receiver for computer graphics video and unbalanced stereo audio  
signals.  
The TP-141 converts computer graphics video and audio inputs to twisted pair  
signals, and the TP-142 converts the twisted pair signals back into computer  
graphics video, unbalanced stereo and S/PDIF digital audio signals. Together the  
TP-141 and TP-142 form a computer graphics video/audio line transmitter/receiver  
system.  
More specifically, the products feature:  
ï‚·
ï‚·
ï‚·
ï‚·
Highest immunity from any kind of interference  
Resolution up to UXGA  
HDTV compatibility  
Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio outputs  
(TP-142)  
ï‚·
ï‚·
ï‚·
Level (gain) and EQ (peaking) controls (TP-142)  
System range up to 250m (750ft)  
Power Connectâ„¢ System - Only one unit in a system, the transmitter or the  
receiver, needs to be connected to a power source when the devices are  
within 50m (150ft) of each other  
Note: The TP-141 and TP-142 are not compatible with existing Kramer TP units  
such as the TP-121, TP-122, and so on.  
3.1  
About the Power Connectâ„¢ 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  
(164ft) on standard CAT 5 cable. For longer distances, heavier gauge cable  
should be used (TP 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

TP-141, TP-142 - Overview  
 
   
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 TP cable exceeding a distance of 50m, separate power supplies should be  
connected to the transmitter and to the receiver simultaneously.  
3.2  
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.

Defining the TP-141 XGA/Audio Line Transmitter  
The TP-141 is an XGA/stereo audio line transmitter that receives an XGA signal  
and an unbalanced stereo analog audio signal, codes them, and transmits them  
over CAT 5 cable to a TP-142 receiver. Figure 1 defines the TP-141.

Defining the TP-142 XGA/Audio Line Receiver  
The TP-142 is an XGA/audio line receiver that receives the coded CAT 5 signal  
transmitted by a TP-141, decodes it and converts it to XGA, stereo analog and  
S/PDIF digital audio outputs. Figure 2 defines the TP-141.

Connecting the TP-141, TP-142  
Always switch off the power to each device before connecting it to your  
TP-141, TP-142. After connecting your TP-141, TP-142, connect its  
i
power and then switch on the power to each device.  
You can use the TP-141 and TP-142 to configure an XGA / Audio Line-to-Twisted Pair  
Transmitter and Receiver system.  
To connect the TP-141 XGA/Audio Line Transmitter with the TP-142 XGA/Audio  
Line Receiver, as illustrated in Figure 3, do the following:  
1. On the TP-141, connect the XGA source (for example, the graphics card of a  
laptop) to the XGA INPUT 15-pin HD (F) connector.  
2. Connect 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).  
Alternatively, you can connect an XGA source to the XGA INPUT 15-pin HD  
(F) connector, and a separate audio source to the AUDIO IN 3.5mm mini  
jack.  
Cables are not supplied. The complete list of Kramer cables is on our Web site at  
3. On the TP-142, connect the XGA OUT 15-pin HD (F) connector to the XGA  
acceptor (for example, a display).  
4. Connect the AUDIO OUT S/PDIF RCA connector to the digital audio  
acceptor (for example, an AV receiver).  
5. Connect the ANALOG 3.5mm mini jack to the analog audio acceptor (for  
example, a stereo audio recorder).  
6. Connect the LINE OUTPUT RJ-45 connector on the TP-141 to the LINE IN  
RJ-45 connector on the TP-142, via CAT 5 (UTP or STP) cabling, (see  
connector pinouts in Section 4.1).  
7. Connect the 12V DC power adapter to the power socket of either the TP-141  
or the TP-142 and connect the adapter to the mains electricity. The Power  
Connect feature feeds power to the second device. If the second device  
does not power on due to a long line, connect a 12V DC power adapter to  
the second device as well.
