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

Overview

3 Overview
The TP-125 and TP-126 are a high-performance twisted pair transmitter
and receiver for computer graphics video (including HDTV), unbalanced
stereo audio, and RS-232 control commands.
The TP-125 converts computer graphics video, unbalanced stereo analog
audio, and RS-232 control commands to a twisted pair signal, and the
TP-126 converts the twisted pair signal back into computer graphics video,
unbalanced stereo and S/PDIF digital audio, and RS-232 control signals.
Together the TP-125 and TP-126 form a computer graphics/audio line
transmitter/receiver system.
More specifically, the products feature:
Resolution up to UXGA or 1920x1200
HDTV compatibility
Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio
outputs (TP-126)
Level (gain) and EQ (peaking) controls (TP-126)
System range up to 100m (300ft)
This user manual describes the following Kramer TOOLS:
TP-125 UXGA / Audio / Data Line Transmitter, see section 4.1
TP-126 UXGA/Audio/DataLineReceiver, see section4.2
This section describes:
Using shielded twisted pair (STP) / unshielded twisted pair (UTP),
see section 3.1
Recommendations for achieving the best performance, see section 3.2
3.1 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
In applications with high interference, shielded twisted pair (STP) cable is
recommended. However, the cable shield creates a capacitance that
degrades the frequency response of the device. For distances of 50 meters or
less shielded twisted pair (STP) cable is preferred because it provides
interference protection without any apparent degradation.
In applications where either: 1) the source and transmitter or receiver and
destination monitor are disconnected from common ground, or 2) the source
area (building) and destination area have no common ground – STP cable is
preferred. For long-range applications, unshielded twisted pair (UTP) cable

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Your TP-125 / TP-126

is preferred. However, unshielded twisted pair (UTP) cable should be
installed far away from sources of electromagnetic interference such as
electric cables and motors.
It is recommended to use shielded twisted pair (STP) skew-free Kramer cable
BC-SXTP for transmitting VGA signals, and shielded twisted pair (STP)
non-skew-free Kramer BC-STP cable for digital signals.
3.2 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-125/TP-126 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

.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

4.1 Your TP-125 UXGA / Audio / Data Line Transmitter
The TP-125 is a high-performance transmitter that accepts:
A computer graphics input signal
An unbalanced stereo analog audio signal
RS-232 control commands
The TP-125 codes the signals and transmits them over CAT 5 cable to a
TP-126 receiver. The stereo analog audio signal is converted to the digital
audio (S/PDIF) stream before transmitting, thus preserving the quality of
the audio source signals. Commands and data can flow in both directions
via the RS-232 interface, allowing status requests and control of the
destination unit.

Figure 2 and Table 2 define the internal sync polarity switches inside the
TP-125.
Note, that you need to open the TP-125 unit to gain access to the Vs and Hs
Polarity switches. After setting the switches, close the TP-125 unit.

4.2 Your TP-126 UXGA / Audio / Data Line Receiver
The TP-126 is a high-performance receiver obtaining the computer graphics
signal/audio/control data from the Kramer TP-125 via UTP cabling at its
CAT 5 line input. The TP-126 outputs a computer graphics signal, an
unbalanced stereo analog audio signal, a converted digital audio (S/PDIF)
signal, and bi-directional RS-232 control commands and data, to and from the
receiver. The RS-232 interface makes it possible to control virtually any
device over a transmission range of more than 300 feet (more than 100
meters) over UTP cabling. In addition, the TP-126 features:
Level and EQ. control for the UXGA signals
The capability to change the polarity of decoding H and V Sync
24 bit 48kHz S/PDIF digital audio that supplies the highest quality audio
12V DC power
