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 video, audio, presentation, and broadcasting professionals 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 i 2.1 Go to http://www.kramerelectronics.com/support/product_downloads.asp to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.2 Safety Instructions ! 2.3 Caution: There are no operator serviceable parts inside the unit Warning: Use only the Kramer Electronics input power wall adapter that is provided with the unit Warning: Disconnect the power and unplug the unit from the wall before installing Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled.
3 Overview The TP-141 and TP-142 are a high-immunity, extended-range twisted pair transmitter and receiver for computer graphics video and unbalanced stereo audio signals. The TP-141 converts computer graphics video and audio inputs to twisted pair signals, and the TP-142 converts the twisted pair signals back into computer graphics video, unbalanced stereo and S/PDIF digital audio signals. Together the TP-141 and TP-142 form a computer graphics video/audio line transmitter/receiver system.
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 TP cable exceeding a distance of 50m, separate power supplies should be connected to the transmitter and to the receiver simultaneously. 3.
3.3 Defining the TP-141 XGA/Audio Line Transmitter The TP-141 is an XGA/stereo audio line transmitter that receives an XGA signal and an unbalanced stereo analog audio signal, codes them, and transmits them over CAT 5 cable to a TP-142 receiver. Figure 1 defines the TP-141.
3.4 Defining the TP-142 XGA/Audio Line Receiver The TP-142 is an XGA/audio line receiver that receives the coded CAT 5 signal transmitted by a TP-141, decodes it and converts it to XGA, stereo analog and S/PDIF digital audio outputs. Figure 2 defines the TP-141.
# Feature Function 1 LINK LED Illuminates when receiving the correct input signal 2 LEVEL Trimmer Adjusts the output signal level 3 EQ. Trimmer Adjusts the cable compensation equalization level Degradation and VGA/XGA signal loss can result from using long cables (due to stray capacitance), sometimes leading to a total loss of sharpness in high-resolution signals. Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level.
4 Connecting the TP-141, TP-142 i Always switch off the power to each device before connecting it to your TP-141, TP-142. After connecting your TP-141, TP-142, connect its power and then switch on the power to each device. You can use the TP-141 and TP-142 to configure an XGA / Audio Line-to-Twisted Pair Transmitter and Receiver system. To connect the TP-141 XGA/Audio Line Transmitter with the TP-142 XGA/Audio Line Receiver, as illustrated in Figure 3, do the following: 1.
