3 Overview
The Kramer WP-121 wall plate is a line transmitter that accepts a UXGA video
and an unbalanced stereo audio signal, encodes them to a TP (Twisted Pair) signal
and transmits the TP signal to a compatible TP receiver

The WP-121 XGA/Unbalanced Stereo Audio Line Transmitter features:
.
• HDTV compatibility—up to 1080p
• The option to use either

• Kramer Power Connect™
a 9-pin terminal block or RJ-45 output TP connector
• EDID Capture—copies and stores the EDID from a display device
• 12V DC power supply
3.1 About the Kramer Power Connect™ Feature
The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m on
standard CAT 5 cable. For longer distances, heavy gauge cable should be used
(CAT 5 cable is still suitable for the video/audio transmission, but not for feeding
the power at these distances).
For a CAT 5 cable exceeding a distance of 50m, separate power supplies should be
connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are
different levels 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 analog signals where skewing is not an issue. For cases where there is
skewing, our 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 was tested using those cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, the UTP cable should be installed far away from electric cables,
motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
