KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

2.1 Quick Start

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

3 Overview

The TP-145 and TP-146 are high-performance, Twisted Pair (TP) transmitter and

receivers for computer graphics video (including HDTV), unbalanced stereo audio,

and RS-232 control commands.

The TP-145 converts computer graphics video, unbalanced stereo analog audio,

and RS-232 control commands to a TP signal. The TP-146 converts the TP signal

back into computer graphics video, unbalanced stereo and S/PDIF digital audio,

Overview

and RS-232 control signals. The TP-145 and TP-146 together form a computer

graphics/audio/control data line transmitter/receiver system.

More specifically, the products feature:

•Resolution up to WUXGA 1920 x 1200

•HDTV compatibility

•EDID capture and status indication (TP-145)

•Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio outputs

(TP-146)

•Level (gain) and EQ (peaking) controls (TP-146)

•Full duplex RS-232 transmission

•Increased level of protection against noise, spikes, and interference in adverse

environments

•System range up to 200m (656ft)

3.1 Shielded Twisted Pair/Unshielded Twisted Pair

We recommend that you use Shielded Twisted Pair (STP) cable. There are

different categories 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 digital signals and for analog signals where skewing is not an issue.

For cases where there is skewing, our Unshielded Twisted Pair (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

has been tested using STP cables.

Although UTP cable might be preferred for long range applications, the UTP cable

should be installed as far as possible from electric cables, motors, and so on, which

often create electrical interference.

However, since the use of UTP cable might cause non-conformity to

electromagnetic standards, Kramer does not commit to meeting the standard with

UTP cable.

3.2 Defining the EDID

EDID (Extended Display Identification Data1

The EDID includes information, such as, the name of the manufacturer, product

type, timing data supported by the display, display size, luminance data, and (for

digital displays only) the pixel mapping data.

) is a data-structure that the display

provides to describe its capabilities to a graphics card connected to the display’s

source. The EDID enables the source, such as a PC, to “know” what kind of

monitor is connected to the output.

1 EDID is defined by a standard published by the Video Electronics Standards Association (VESA)

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Defining the TP-145/TP-146

The TP-145 can store and recall EDID data in non-volatile memory, allowing

convenient and reliable connection to the source.

3.3 Recommendations for Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality, and position your Kramer TP-145/TP-146 away

from moisture, excessive sunlight and dust

to avoid interference, deterioration

in signal quality due to poor matching, and elevated noise levels (often

associated with low-quality cables)

4 Defining the TP-145/TP-146

This section defines the:

•TP-145, XGA/Audio/Data Line Transmitter (see Section 4.1)

•TP-146, UXGA/Audio/Data Line Receiver (see Section 4.2)

4.1 Defining the TP-145 XGA/Audio/Data Line Transmitter

The TP-145 is a high-performance transmitter that accepts:

•A computer graphics input signal

•An unbalanced stereo analog audio signal

•RS-232 control commands

The TP-145 encodes the signals and transmits them over TP cable to a TP-146

receiver. The stereo analog audio signal is converted to a digital audio (S/PDIF)

stream before transmission, thus preserving the quality of the audio source signals.

Commands and data can flow in both directions simultaneously via the RS-232

interface, allowing status requests and control of the destination unit.

When the TP-145 is connected to a display device and the EDID CAPTURE

button is pressed, the TP-145 reads and stores the EDID (Extended Display

Identification Data) from the display device. This prevents the problem whereby a

Defining the TP-145/TP-146

source (for example, a PC), fails to output video because it was not connected to

the display device when attempting to read its EDID.

Figure 1 and Table 1 define the TP-145.

4.2 Defining the TP-146 UXGA/Audio/Data Line Receiver

The TP-146 is a high-performance receiver that accepts the computer graphics

signal/audio/control data from the Kramer TP-145 via TP cabling at its RJ-45

LINE IN input. The TP-146 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. The RS-232 interface makes it

possible to control virtually any device over a transmission range of up to 200m

(660ft) with a Kramer TP-141/145 transmitter over TP cabling. In addition, the

TP-146 features:

•Level and Equalization control for the UXGA signal

•The capability to change the polarity of the vertical and horizontal sync signals

•24 bit 48kHz S/PDIF digital audio

1 Degradation and UXGA signal loss can result from using long cables (due to stray capacitance), sometimes leading to a total loss of

sharpness in high-resolution signals
