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

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 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-145/TP-146 away  
from moisture, excessive sunlight and dust

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

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

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
