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

3 3

and RS-232 control signals. The TP-145 and TP-146 together form a computer
graphics/audio/control data line transmitter/ rec eiver 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 E Q (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 di gital sig nals and fo r analog s ignals whe re skewing is not an issue.
For cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-free
cable, Kramer BC-XTP, may be us ed. 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 Defi n ing the EDID

EDID (Extended Display Identification Data

1

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 d isplay
provides to describ e its ca pabilities to a graphics card connected to the displa y’s
source. The EDID enables the source, such as a PC, to “know” what kind of
monitor is connected to the ou tput.

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

4

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 cables

1

• Avoid interference from neighboring electrical appliances that may adversely

influence signal qualit y, a nd position your Kramer TP-145/TP-146 away
from moisture, excessive s unlight and dust

to avoid interference, d e te rioration
in signal quality due to poor matching, and e levated no ise level s (often
associated with low-quality cables)

4 Defining the TP-145/TP-146

This sect ion 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 Defi n ing the TP-145 XGA/Audio/Data Line Transmitter

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

• A compute r graphics input signal

• An unbalanced stereo analog audio signal

• RS-232 control commands

The TP-145 encodes the signals and transmits the m 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 R S-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 r ead s and stores the EDID (Extended Display
Identification Data) fro m the display device. This prevents the problem whereby a

source (for example, a PC), fails to output video because it was not connected to
the display device when attempting to read its ED ID.

4.2 Defi n ing the TP-146 UXGA/Audio/Data Line Receiver

The TP-146 is a high-performance receiver that accepts the computer graphics
signal/audio/control da ta 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 c onverted digital audio (S/PDIF) signal, and bi­directional RS-232 control commands and data. The RS-232 interface makes it
possible to control virtuall y any device over a transmission range of up to 200m
