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™

• 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.

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.
