Introduction 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. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Overview 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps. 3 Overview The TP-145 and TP-146 are high-performance, Twisted Pair (TP) transmitter and receivers for computer graphics video (including HDTV), unbalanced stereo audio, and RS-232 control commands. The TP-145 converts computer graphics video, unbalanced stereo analog audio, and RS-232 control commands to a TP signal.
Overview and RS-232 control signals. The TP-145 and TP-146 together form a computer graphics/audio/control data line transmitter/receiver system.
Defining the TP-145/TP-146 The TP-145 can store and recall EDID data in non-volatile memory, allowing convenient and reliable connection to the source. 3.
Defining the TP-145/TP-146 source (for example, a PC), fails to output video because it was not connected to the display device when attempting to read its EDID. Figure 1 and Table 1 define the TP-145.

Defining the TP-145/TP-146 (660ft) with a Kramer TP-141/145 transmitter over TP cabling. In addition, the TP-146 features: • Level and Equalization control for the UXGA signal • The capability to change the polarity of the vertical and horizontal sync signals • 24 bit 48kHz S/PDIF digital audio Figure 2 and Table 2 define the TP-146 UXGA/Audio/Data Line Receiver.
Connecting the TP-145 and the TP-146 4.2.1 Internal Polarity and Sync Mode Switches Figure 3 and Table 3 define the internal horizontal and vertical polarity switches of the TP-146. Note: You need to open the TP-146 unit to gain access to the Hs and Vs polarity and video selection switches which are located on the lower part of the printed circuit board next to the ON LED. After setting the switches, close the TP-146.
Connecting the TP-145 and the TP-146 Figure 4: Connecting the UXGA/Audio/Data Line Transmitter/Receiver System To connect the TP-145 and the TP-146 to create a TP transmitter and receiver system, as illustrated in Figure 4: 1. On the TP-145, connect: A UXGA source (for example, the graphics card on a laptop) to the UXGA IN 15-pin HD (F) connector An audio source to the AUDIO IN 3.
Connecting the TP-145 and the TP-146 An RS-232 cable with a 3 pin terminal block connector at one end to the TP-146 RS-232 port 1, and a 9-pin D-SUB connector at the other end to the RS-232 port on the AV display system 3. Using STP cabling 2, connect the LINE OUT RJ-45 connector on the TP-145 to the LINE IN RJ-45 connector on the TP-146. 4. Connect the power adapter to the power socket on the TP-145 and/or TP-146 (if needed), and connect the adapter(s) to the mains electricity. 5.
