1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
2 Getting Started We recommend that you: • Unpack the equipment carefully and save the original box and packaging materials for possible future shipment • Review the contents of this user manual • Use Kramer high performance high resolution cables i 2.1 Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
3 Overview The Kramer TP-122N is an XGA/audio line receiver that receives the coded CAT 5 signal transmitted by a TP-121EDID XGA / Audio Line Transmitter, for example, decodes it and converts it to XGA, stereo analog and S/PDIF digital audio outputs. The TP-122N, with the TP-121EDID transmitter, allows an operation range of more than 300ft (more than 100m) over standard CAT 5 cable. The TP-122N: • Is HDTV Compatible • Has a maximum resolution of WUXGA and 1080p • Includes EQ.
3.2 About 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 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).
3.3 Defining the TP-122N XGA/Audio Line Receiver This section defines the TP-122N.

4 Connecting the TP-122N XGA/Audio Line Receiver You can use the TP-121EDID and TP-122N to configure an XGA/Audio Lineto-Twisted Pair Transmitter and Receiver system. To connect the TP-121EDID XGA/Audio Line Transmitter with the TP-122N XGA/Audio Line Receiver, as the example in Figure 2 illustrates, do the following: 1. On the TP-121EDID, connect the XGA source (for example, a laptop’s graphics card) to the XGA INPUT 15-pin HD (F) connector and an audio source to the AUDIO IN 3.
