Two small receivers can allow the sending of very high resolution video signals, up to 60Hz, to a maximum distance of 70 meters.This is how the TECHly system worksDesigned for an industrial installation, IDATA HDMI-EX60-H2 is a point-to-point extender sold by TECHly that is used to distribute an HDMI V2.0 signal up to 70 meters using a Cat5e or Cat6 network cable (not supplied) .The system can then send a video signal over very long distances and bypassing the limitations of HDMI cables.HDMI-EX60-H2 includes two devices (receiver and transmitter), supports 4K Ultra HD video resolution up to 60Hz with Chrome 4: 4: 4 sampling.and can transfer HDMI data up to 18Gbps supporting HDCP 2.2 standard.If needed, resizing in Full HD is also supported.HDMI is an extremely popular standard as a digital connectivity solution between audio-visual devices, however it imposes important limits in terms of range.For a consumer user this is not a big deal as cables that are a few meters long are quite cheap, but those over 10 meters cost a lot.And, due to signal degradation over long distances, HDMI cables of more than 30 meters are very rare.If you need a longer range, you can opt for an extender, such as the Techly models that use Ethernet cables to connect two HDMI devices placed at great distances to each other.The company produces models capable of connecting distances of several tens of meters, well beyond the capabilities granted by the HDMI standard, and in this case we are talking about HDMI Type-A port to connect the display, which reaches a range of up to 70 meters.This model can also manage EDID data, through a paper clip to be inserted into a hole.Before seeing what it is, let's briefly explain what EDID is.EDID is the acronym for Extended Display Indentification Data, a protocol developed by VESA that is used for the exchange of data between display and source specifically to communicate the characteristics of the former to the latter.In this way the source can establish the native resolution to be adopted, the frequency, and all the information necessary to ensure that the video stream is compatible with the characteristics of the display, and not generate conflicts or incompatibilities.Ultimately, the protocol allows to optimize the visual rendering by obtaining the maximum quality guaranteed by the components without accessing manual configurations.Considering the long distances covered, it is clear that the system is equipped with a bidirectional infrared control system, and promises zero compression and zero latency, since Ethernet cables are used that can support very high transfer rates.The small dimensions also allow for simple installation in the room, with great ease also in the configuration.The power supplies are also provided in the official equipment.The transmitter is the more complex device of the two, and has several ports.Here they are below:The receiver is instead equipped with the following ports:But how do you use the IDATA HDMI-EX60-H2 system?For example, if we have a TV connected to a Bluray player or any type of source in room A and we want to reproduce its contents on a display connected in a very distant room B, we can simply connect the transmitter in room A to the receiver in room B .The diagram is: Blu-ray or source in the Source port of the transmitter, eventual monitor of the environment A in the Display port of the transmitter and Ethernet cable in the CATx Out output always in the transmitter.The other end of the latter must end up in the CATx In of the receiver in room B, which can be connected via HDMI with the display that should be nearby.With the IR In and Out ports we can connect any cables supplied: the IR transmitter naturally in the transmitter, the IR receiver in the receiver.In this way, with the same remote control we will be able to control the Blu-ray also in room B, where they will be seen in content being played.The IDATA HDMI-EX60-H2 kit is sold on Manhattan Shop at a price of approximately 200 euros, to which the costs for the Ethernet cable must be added.The equipment includes the two devices, IR receiver and emitter, two cable ties, a DC12V 1A power supply and the exhaustive instruction manual.
