We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
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)
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
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.

before installing
2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

TP-141, TP-142 - Overview
3 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:
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)
Level (gain) and EQ (peaking) controls (TP-142)
System range up to 250m (750ft)
Power Connect™ 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 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
(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

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.

3.3 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.

3.4 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.
