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,

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)
