2 Getting Started
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.

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

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

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.

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.

4 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
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
http://www.kramerelectronics.com
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.
