3 Overview

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

For example, the Kramer TP-122/N or TP-122-od.

The WP-121XGA/Unbalanced Stereo Audio Line Transmitter features:

HDTV compatibility up to 1080p

The option to use either a 9-pin terminal block or RJ-45 output TP connector

Only one can be connected at a time to a TP receiver. Connecting both simultaneously results in neither operating

Kramer Power Connect™

EDID Capture copies and stores the EDID from a display device

12V DC power supply

3.1About the 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 (164ft) 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 units which are connected via RJ-45 connectors, make sure that the shield of the STP cable is connected to the metal casing of the connectors on both ends of the cable. For units which are connected via terminal block connectors, the shield of the STP cable must be connected to a ground terminal on the units at both ends (use the ground terminal of the power supply connection if necessary).

For a CAT 5 cable exceeding a distance of 50m, separate power supplies should be connected to the transmitter and to the receiver simultaneously.
