•System range up to 200m (656ft)

3.1Shielded Twisted Pair/Unshielded Twisted Pair

We recommend that you use Shielded Twisted Pair (STP) cable. There are different categories 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-STPis intended for digital signals and for analog signals where skewing is not an issue. For cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-free cable, Kramer BC-XTP, may be used. Bear in mind though, that we advise using STP cables where possible, since the compliance to electromagnetic interference has been tested using STP cables.

Although UTP cable might be preferred for long range applications, the UTP cable should be installed as far as possible from electric cables, motors, and so on, which often create electrical interference.

However, since the use of UTP cable might cause non-conformity to electromagnetic standards, Kramer does not commit to meeting the standard with UTP cable.

3.2Defining the EDID

EDID (Extended Display Identification Data1) is a data-structure that the display provides to describe its capabilities to a graphics card connected to the display’s source. The EDID enables the source, such as a PC, to “know” what kind of monitor is connected to the output.

The EDID includes information, such as, the name of the manufacturer, product type, timing data supported by the display, display size, luminance data, and (for digital displays only) the pixel mapping data.

1 EDID is defined by a standard published by the Video Electronics Standards Association (VESA)

tp-145 specifications

Kramer Electronics is synonymous with high-quality audio-visual products, and their TP-145 model stands out as a noteworthy solution for signal extension and transmission. The TP-145 is primarily designed as a twisted pair transmitter that allows for the seamless transfer of HDMI signals over a long distance. This capability makes it an ideal choice for professional AV installations where maintaining signal integrity and quality is crucial.

One of the standout features of the TP-145 is its ability to support resolutions up to 4K at 60Hz, ensuring that users can enjoy ultra-high-definition video output. This makes the TP-145 particularly appealing for environments such as conference rooms, educational institutions, and event spaces, where high-quality visuals are essential for presentations and demonstrations.

To facilitate easy integration into various setups, the TP-145 employs both HDMI and balanced twisted pair (UTP) transmission technology. This allows users to connect their HDMI sources to a compatible display device without the hassle of complex wiring or additional converters. The device supports distances of up to 70 meters (230 feet) when using CAT6a cables, providing flexibility in installation setups and making it viable for larger spaces.

The TP-145 also features advanced color depth support, which extends to 4:4:4 chroma subsampling, ensuring that colors remain vibrant and true to life over long cable runs. Additionally, the product is equipped with HDMI audio extraction capabilities, allowing users to extract audio signals separately, a particularly useful feature in scenarios where sound systems require different audio pathways.

Another critical characteristic of the TP-145 is its robust build quality designed to withstand the rigors of professional environments. It features a compact form factor that allows for easy mounting configurations, whether on racks or directly on surfaces. Furthermore, the user-friendly design includes LED indicators which provide real-time feedback on signal status, simplifying troubleshooting and installation processes.

In conclusion, the Kramer Electronics TP-145 combines cutting-edge technology with practical features, making it a top choice for professionals in need of reliable HDMI signal transmission solutions. With its exceptional performance capabilities, versatility in installation, and durable design, it stands as a reliable solution for any AV application.
