WP-120 - Overview

Overview
The Kramer
WP-120
wall plate is an XGA line receiver that receives an encoded
CAT5 signal transmitted by a transmitter (for example, the Kramer
WP-110
or
PT-110
), decodes it and converts it to an XGA output. In particular, the
WP-120
features:
EQ. and level controls
The Power Connect™ feature where a single connection to the transmitter or
the receiver powers both units when the devices are within 150ft (50m) of
each other
12V DC power

About the Power Connect Feature
The Power Connect feature applies as long as the cable can carry power. The
distance does not exceed 50 meters on standard CAT 5 cable. For longer
distances, heavy gauge cable should be used. For a CAT 5 cable exceeding a
distance of 50 meters, separate power supplies should be connected to the
transmitter and to the receiver simultaneously.
CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at
these distances
3.2
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 shield itself does create a capacitance that degrades
the frequency response of the machines. For shorter distances, of 50m or so,
shielded twisted pair (STP) cable is preferred because it provides protection from
interference (degradation is not apparent).
For long range applications, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away
