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 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).
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−45EDID is a high−performance twisted pair transmitter for computer graphics or component video and unbalanced stereo audio signals. It converts the input signals to a twisted pair signal and transmits them over CAT 5 cable to a compatible receiver. The TP-45EDID has two SELECT buttons that let you choose the video signal input (XGA or component) as well as the audio input (digital or analog signal). (The term XGA used throughout this manual implies resolutions exceeding UXGA.
• EDID capture that copies and stores the EDID from a display device • The Power Connect™ feature where one unit can power the other over the same CAT 5 cable • 12V DC power • Toggling push-button selector switches and status LEDs connected by a remote selector input terminal block 3.1 Shielded Twisted Pair (STP)/Unshielded Twisted Pair (UTP) We recommend that you use Shielded Twisted Pair (STP) cable, and stress that the compliance to electromagnetic interference was tested using STP cable.
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 Defining EDID The Extended Display Identification Data (EDID) is a data-structure provided by a display, to describe its capabilities to a graphics card (that is connected to the display’s source). The EDID enables the TP-45EDID to “know” what kind of monitor is connected to the output.
4 Defining the TP-45EDID Component/UXGA/Audio Transmitter This section defines the TP-45EDID.
# Feature XGA IN 15-pin HD (F) Connector Connect to the XGA source 2 LINE OUT RJ-45 Connector Connect to the LINE IN connector of the receiver 3 EDID Status LED Illuminates during normal operation; flashes when acquiring the EDID 4 EDID CAPTURE Button Press to acquire the EDID information from the display 5 CONTROL AUDIO/VIDEO Terminal Block Connect to remote push-button switches and status LEDs 6 12V DC +12V DC connector for powering the unit 7 ANALOG AUDIO 3.
5 Connecting a Component/XGA – Audio Distribution System The Component/XGA – Audio Distribution System can be configured to operate in one of two video modes: • In the XGA mode, a computer graphics source is connected to the input and transmitted to a display connected to the receiver (see Section 5.1) • In the component video mode, a component video source is connected to the input and transmitted to a TV set connected to the receiver (see Section 5.
5.1 Connecting the System in XGA Mode To configure a TP-45EDID and TP-46N Component/XGA – Audio distribution system (using up to 300ft (100m) of UTP cabling) in the XGA mode, as illustrated in the example in Figure 2, do the following: 1. On the TP-45EDID, connect the following: An XGA source (for example, the graphics card on a laptop) to the XGA 15-pin HD (F) connector An analog audio source to the ANALOG AUDIO 3.
7. On the TP-46N underside: Using a screwdriver to carefully rotate the trimmer, adjust the video output signal level and/or cable compensation equalization level, if required Figure 2: Component/XGA – Audio Distribution System, XGA Mode 5.2 Connecting the System in Component Video Mode To configure a TP-45EDID/TP-46N Component/XGA – Audio distribution system in the component video mode, as the example in Figure 3 illustrates, do the following: 1.
2. On the TP-45EDID, use the SELECT buttons as follows: Momentarily press the VIDEO SELECT button. The UXGA LED turns off when the component video input is selected Momentarily press the AUDIO SELECT button to toggle between the S/PDIF and analog audio inputs 3.
Figure 3: Component/XGA – Audio Distribution System, Component Video Mode 5.3 Connecting the TP-45EDID Remote Control Connect momentary push-buttons and LEDs (each LED is driven by a 5V source and a 392Ω series resistor) to a cable and attach the cable to a 5-pin terminal block for connection to the TP-45EDID control port as shown in Figure 4. Each press of the selector button toggles the audio or video system mode and turns on or off the remote and panel status LEDs according to the active mode.
Figure 4: The TP-45EDID Remote Control Connection 5.4 Wiring the CAT 5 LINE IN / LINE OUT RJ-45 Connectors This section defines the CAT 5 pinout, using a straight pin-to-pin cable with RJ-45 connectors. i Note, that the cable Ground shielding must be connected / soldered to the connector shield.
6 Acquiring the EDID The transmitter can acquire the EDID information from the display connected to the transmitter or acquire the default EDID. To acquire the display EDID, do the following: 1. Connect the XGA INPUT 15-pin HD connector to the input XGA connector of the display, using a short cable. The EDID is carried over pins 12 and 15 of the VGA connector. It is essential that the cable used for capturing the EDID passes all 15 pins 2. Connect power to the display. 3.
