4 TP-45EDID - Overview

3 Overview

The TP−45EDID is a high−performance twisted pair transmitter for computer
graphics or component video and unbalanced stereo audio signals. It converts the
input signals to a twisted pair signal and transmits them over CAT 5 cable to a
compatible receiver.

The TP-45EDID has two SELECT buttons that let you choose the video signal
input (XGA or component) as well as the audio input (digital or analog signal).
(The term XGA used throughout this manual implies resolutions exceeding
UXGA.) By selecting the required video input signal, the TP-45EDID with the
TP-46N can constitute either a component video (Y, C

B/PB, CR/PR) or an XGA

video – audio transmitter / receiver system:

The TP-45EDID does not convert the video signal format. Thus computer graphics sources
must be routed to computer graphics outputs. Similarly, component video sources must be
routed to component video outputs.

• If XGA is sele cte d, the TP-45EDID receives an XGA and audio signal and

transmits it over the CAT 5 cable to the XGA output on the TP-46N receiver

• If component video is selected, the component video signal is transmitted

over the CAT 5 cable to the COMP outputs on the TP-46N receiver

• The analog audio or S/PDIF (digital audio)—as selected via the audio

SELECT button—is transmitted together with the video signal over the CAT
5 cable to the TP-46N receiver

• The TP-45EDID can execute these control funct i ons also remotel y using

simple pushbuttons (see Section

5.3)

The audio signal is distributed simultaneously to the analog or digital audio
outputs.

The TP-45EDID Component/XGA – Audio Transmitt er f eatures :

• Transmission range of more than 300ft (more than 100m)

• YUV input (also known as Y, Cb, Cr, or Y, B-Y, R-Y, or Y, Pb, Pr) on 3 RCA

connectors and a computer graphics input on a 15-pin HD (F) connector

• Digital audio input (S/PDIF) on an RCA connector and a stereo analog input

on a 3.5mm mini jack

TP-45EDID - Overview 5

• EDID capture that copies and stores the EDID from a display device

• The Power Connect™ feature where one unit can power the other over the

same CAT 5 cable

• 12V DC power

• Toggling push-button selector switches and status LEDs connected by a

remote selector input terminal block

3.1 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 interferenc e 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.

3.2 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, heavy gauge cable should
be used (TP cable is still suitabl e for the video/audi o transmission, but not for
feeding the power at these distances). 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).

6 TP-45EDID - Overview

For a TP cable exceeding a distance of 50m, separate power supplies should be
connected to the transmitter and to the receiver simultaneously.

3.3 Defining EDID

The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the TP-45EDID to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
the product type, the timing data supported by the display, the display size,
luminance data and (for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).

TP-45EDID - Connecting a Component/XGA – Audio Distribution System 9

5 Connecting a Component/ X GA – Audio

Distributi on System

The Component/XGA – Audio Distribution System can be configured to operate in
one of two video modes:

• In the XGA mode, a computer graphics source is connected to the input and

transmitted to a display connected to the receiver (see Section

5.1)

• In the component video mode, a component video source is connected to

the input and transmitted to a TV set connected to the receiver (see

Section

5.2)

The Component/XGA – Audio Distribution System can be configured to operate in
one of two audio modes:

• In the analog mode, an analog audio source is connected to the input and

transmitted to an acceptor connected to the receiver (see Section

5.1)

• In the digital audio mode, an S/PDIF audio source is connected to the input

and transmitted to a digital acceptor connected to the receiver (see

Section

5.2)

Thus, there are four possible system configurations: computer graphics/anal og
audio, computer graphics/digital audio, component video/anal og audio, and
component video/digital audio.

The modes of the system are determined by setting the VIDEO SELECT and
AUDIO SELECT switches on the TP-45EDID. Whatever modes are set at the
transmitter the video and audio signals are sent to the receiver and any additional
cascaded receivers.

There is no signal conversion; a component input cannot be sent to a computer graphics
output, nor can a digit al audio input be sent to an analog audi o outp ut .

TP-45EDID - Acquiring the EDID 15

6 Acquiring the EDID

The transmitter can acquire the EDID information from the display connected to
the transmitter or acquire the default EDID.

To acquire the display EDID, do the following:

1. Connect the XGA INPUT 15-pin HD connector to the input XGA connector of
the display, using a short cable.

The EDID is carried over pins 12 and 15 of the VGA connector. It is essential that the
cable used for capturing the EDID passes all 15 pins

2. Connect power to the display.

3. On the transmitter, connect the 12V DC power adapter to the power socket
and connect the adapter to the mains electricity.

4. Press the EDID CAPTURE button.

5. Once the EDID STATUS LED flashes slowly several times, the EDID is
captured.

6. Disconnect the display.

To acquire the default EDID:

Do not connect the display to the transmitter when acquiring the default EDID.

1. On the transmitter, connect the 12V DC power adapter to the power socket
and connect the adapter to the mains electricity.

2. Press the EDID CAPTURE button.

3. Once the EDID STATUS flashes rapidly several times, the default EDID is
captured.

Alternatively, you can press the EDID CAPTURE button after connecting the
transmitter receiver system. When the EDID STATUS LED flashes rapidly several
times, the default EDID information is acquired.
