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).
2.3 Shielded Twisted Pair/Unshielded Twisted Pair We recommend that you use Shielded Twisted Pair (STP) cable, and stress that the compliance to electromagnetic interference was tested using STP cable. There are different levels of STP cable available, and we advise you to use the best quality STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is intended for analog signals where skewing is not an issue.
3 Overview The TP-125xl and TP-126xl are a high-performance, TP (Twisted Pair) transmitter and receiver pair for transmitting computer graphics video, unbalanced stereo audio, and bidirectional RS-232 data signals over extended distances using CAT 5/6 cable. The TP-125xl encodes computer graphics video, unbalanced stereo audio and RS-232 data into a TP signal. The TP-126xl decodes the TP signal into computer graphics video, digital unbalanced stereo audio, and RS-232 data signals.
4 Defining the TP-125xl/TP-126xl Line Transmitter and Receiver This section defines the: TP-125xl UXGA/Audio/Data Line Transmitter (see Section 4.1) TP-126xl UXGA/Audio/Data Line Receiver (see Section 4.2) The TP-125xl has inputs for: Computer graphics video Unbalanced stereo audio RS-232 data The TP-125xl encodes the video, audio and data signals and transmits them over STP cable to a TP-126xl receiver.
4.1 Defining the TP-125xl UXGA/Audio/Data Line Transmitter Figure 1 defines the front panel of the TP-125xl.
4.2 Defining the TP-126xl UXGA/Audio/Data Line Receiver Figure 3 defines the front panel of the TP-126xl. Figure 3: TP-126xl UXGA/Audio/Data Line Receiver Front Panel # Feature Function 1 LINK LED Lights green when the TP link is established 2 LEVEL Trimmer Use to adjust the output signal level (see Section 6.2) 3 EQ. Trimmer Use to adjust the cable compensation equalization level 4 ON LED Lights green when the device is powered on Figure 4 defines the rear panel of the TP-126xl.
5 Connecting the TP-125xl and TP-126xl i Switch off the power to all devices before connecting them to your TP-125xl/TP-126xl. After connecting your TP-125xl/TP-126xl, connect the power to the transmitter and receiver and then switch on the power to the other devices. Figure 5: Connecting the TP-125xl Transmitter and TP-126xl Receiver To connect the TP-125xl and the TP-126xl as illustrated in Figure 5: 1.
The RS-232 controller, (for example, a laptop controller with an RS-232 interface) to the RS-232 3-pin terminal block An unbalanced, stereo audio source, (for example, the audio output from a laptop) to the Audio In 3.5mm mini jack 2. On the TP-126xl, connect: The UXGA Out 15-pin HD (F) connector to the video acceptor, (for example, an AV display system) The RS-232 3-pin terminal block to the controlled device, (for example, an AV display system) The Audio Out Analog 3.
6 Operating the TP-125xl and TP-126xl 6.1 Capturing the EDID The TP-125xl is programmed with a default EDID. To replace the default EDID you can replace it with the EDID from a display device. To capture a new EDID: With the display device connected to the TP-125xl, press the EDID Capture button on the front panel of the TP-125xl. If the EDID is successfully captured the Status LED flashes slowly for a few seconds and then lights solid.
7 Wiring the Twisted Pair RJ-45 Connectors When using STP cable, connect/solder the cable shield to the RJ-45 connector shield. Figure 6 defines the TP pinout using a straight pin-to-pin cable with RJ-45 connectors.
8 Technical Specifications TP-125xl INPUTS: BANDWIDTH: S/N RATIO: Audio: 84dB unweighted COUPLING: AC TND+N: Audio: 0.02% unweighted TOTAL GAIN: Analog/analog: 0dB Analog/SPDIF: –12dBFS 9600, 19200bps OUTPUTS: VIDEO RESOLUTION: MAX.
