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) when using the Kramer
BCP-HDTP cable, or 600ft when using our standard skew free
cable, such the BC-XTP
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. The
distance does not exceed 50 meters on standard CAT 5 cable, for longer
distances, heavy gauge cable should be used
1
.
For a CAT 5 cable exceeding a distance of 50 meters, 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 STP skew-free cable: Kramer
BC-SXTP, is intended for transmitting VGA signals; our non-skew-free
cable: Kramer BC-STP, is intended for digital signals.
The compliance to electromagnetic interference was tested using STP
cables, therefore we recommend 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 cables
1
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 and position your Kramer
TP-141/TP-142 away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

polarity switches (see section 4.1.2) 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:

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.

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 5, 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)
1
.
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.
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 5.1).
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.
8. On the TP-142:
