3 Overview
The TP-125 and TP-126 are a high-performance twisted pair transmitter
and receiver for computer graphics video (including HDTV), unbalanced
stereo audio, and RS-232 control commands.
The
TP-125 converts computer graphics video, unbalanced stereo analog
audio, and RS-232 control commands to a twisted pair signal, and the
TP-126 converts the twisted pair signal back into computer graphics video,
unbalanced stereo and S/PDIF digital audio, and RS-232 control signals.
Together the TP-125 and TP-126 form a computer graphics/audio line
transmitter/receiver system.
More specifically, the products feature:
Resolution up to UXGA or 1920x1200
HDTV compatibility
Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio
outputs ( TP-126)
Level (gain) and EQ (peaking) controls ( TP-126)
System range up to 100m (300ft)

3.1 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
In applications with high interference, shielded twisted pair (STP) cable is
recommended. However, the cable shield creates a capacitance that
degrades the frequency response of the device. For distances of 50 meters or
less shielded twisted pair (STP) cable is preferred because it provides
interference protection without any apparent degradation.
In applications where either: 1) the source and transmitter or receiver and
destination monitor are disconnected from common ground, or 2) the source
area (building) and destination area have no common ground – STP cable is
preferred. For long-range applications, unshielded twisted pair (UTP) cable
