2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

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 exceeding 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 on standard CAT 5 cable. For longer distances, heavy gauge
cable should be used1.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.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
We recommend that you use Shielded Twisted Pair (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. For
cases where there is skewing, our UTP skew-free cable, Kramer BC-XTP,
may be used. Bear in mind, though, that we advise using STP cables where
possible, since the compliance to electromagnetic interference was tested
using those cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to
electromagnetic standards, Kramer does not commit to meeting the standard
with UTP cable.
3.3 Recommendations for Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables1to 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 and position your Kramer
TP-141/TP-142 away from moisture, excessive sunlight and dust

This section defines the TP-141 XGA/Audio Line Transmitter (see section
4.1), and the TP-142 XGA/Audio Line Receiver (see section 4.2).
4.1 Your TP-141 XGA/Audio Line Transmitter
This section describes the topside (see section 4.1.1) of the TP-141
XGA/Audio Line Receiver.
4.1.1 Your TP-141 XGA/Audio Line Transmitter (Topside)
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 and Table 1 define the TP-141:

4.2 Your TP-142 XGA/Audio Line Receiver
This section describes the topside (see section 4.2.1), and the underside (see
section 4.2.2) of the TP-142 XGA/Audio Line Receiver.
4.2.1 Your TP-142 XGA/Audio Line Receiver (Topside)
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 and Table 2 define the topside of the TP-142 XGA/Audio Line

5 Connecting the XGA/Audio Line Transmitter/Receiver
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 4, 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)2.
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.
1 By default, both switches are set to the left (for a negative V SYNC and H SYNC polarity)
