Getting Started

2.1 Quick Start

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

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.

4.1.1 The TP-125 Internal Polarity Switches

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
