Hello Skooter Blog readers. Today I talk about the two Baluns Passive Transceiver 4 Video Channels (CCTV) via Twisted Pair, 330m maximum (4-CH CCTV via Twisted Pair Passive Video Balun Transceiver (Max 330m)), acquired na DX – DealExtreme e cuja purchase has been reported in a previous article aqui no Skooter Blog.
Este by Baluns Transceivers Liabilities 4 Video Channels (CCTV) via Twisted Pair, 330m maximum (4-CH CCTV via Twisted Pair Passive Video Balun Transceiver (Max 330m)) It was purchased to make a point of slave Sky, using a single plane and discrete network cable to transmit the composite video signal and stereo audio, so that I could take it quietly on the bottom of the house from one room to the other. Could have done it with 3 coaxial cable without the need to use baluns, but the volume of the coaxial cable is much higher, and the price also.
I already had a Sky slave point made with the Transmitter / Receiver A / V Extender with Wireless Remote Control 5.8GHz Pakite PAT-530 (PAT-530 5.8GHz Wireless A/V STB Transmitter/Receiver with IR Signal Extension Wire Set (Blue)), Also acquired in DX. But any interference intensified and became unbearable after I installed Roteador Wireless Gigabit 1300Mbps ASUS RT-AC66U (ASUS RT-AC66U 1300 Mbps Gigabit Wireless Router). I could even disable the 5.8GHz network in Router or problem solving, or try using different channels and less bandwidth, but that would be a potential waste of Router. Furthermore, the 2.4GHz band has been terrible here, I think because of the neighbors also have routers in this range. At least 5.8GHz band still only have my, then I must use it.
The scheme to make Sky's the slave point with Baluns It is simple. My decoder is still the oldest, Philips, who came with two composite video outputs, and two outputs of each audio channel. This makes it easy to connect a set of outputs on the main TV and the other set on TV with the slave point. Moreover, these older decoders are well above the super compact garbage that Sky are installing now. The old has S-Video output, giving a much higher image with respect to the composite video output that is the only available on the new decoder. The former can use standard cables, the new one has the audio and video outputs on a mini-DIN plug, so that if the bum cable that comes along break, you have to ask another to Sky. The former has optical digital audio output, is not new. The old modem and has, therefore, the pay-per-view purchases can be made by remote control, the new has no modem, shopping only by phone.
And worst of all is that Sky decided to change some of these older decoders (RCA which are even older, as yet said nothing about the Philips) the new, claiming that the former no longer work. The attendants have the nerve to say that the new is better and uses a more advanced technology. What's best and most advanced in taking the S-Video and composite video only leave? If you still have HDMI… What's the latest in again need a phone to buy something in the pay-per-view? This is back at least a 20 time in years! And the pearl of the year: an attendant tried to convince me that the exchange was advantageous because the new device had USB input. But she forgot to mention that the USB port in question does not serve to damn thing!
But the method returning to connect. If you have the device with two sets of output, just use the second game that probably will be free. If you have decoder with only one exit, may risk double outputs with adapters, but there may be some loss of quality. As League 3 outputs (composite and stereo audio video) in 3 the 4 um entries Balun, with the aid of a triple RCA cable and 3 BNC to RCA adapters. I used the channel 1 video, the channel 3 for left audio channel and 4 to the audio right, but the choice of channels should have minimal impact on the quality (if they have any). No plug RJ45 do Balun connects to a twisted pair cable (After rede), that should be taken to the location of the slave point. At the site of the slave point is just go the other way: binds the twisted pair cable into the RJ45 input of another Balun, e league-se a triple RCA cable, with the help of more 3 BNC to RCA adapters in one TV input. Soon! What do you tune the decoder will also appear on the TV slave point.
Which cable network use? Will depend on the distance. With 15 meters I used a cable unbranded bum plan did not pay for network, or to 10Mbps Ethernet served. A DX I repaid by him and bought a best of PowerSync. Thereafter, almost threw the bum flat cable out, but I ended up saving if someday serve for something. Not that served the same? Maybe it was to be only 15 meters, but picture and sound were perfect. I can not notice any difference between turning on the decoder directly to the TV and connect through Baluns with 15 meters of twisted pair cable and over the pair of triple RCA cables, totaling nearly 20 meters.
For longer distances it may be good to use a good twisted pair cable cat5e, or even a cat6 cable. But the big advantage is that these cables cost much less to use three coaxial cables, what would be the alternative that offer similar quality, besides occupy much less space in conduits, and be more discreet in an apparent installation. The operating principle is simple. Each of the 3 RCA cable has a center conductor and a mesh, totaling 6 drivers. A single twisted pair cable has 8 drivers, then what Balun do is simply this adaptation / conversion of the signal 3 RCA pass by cables 3 of 4 twisted pairs that the network cable has, and still have a couple more for any other use. Theoretically gives up using cables 330 meters, which should be sufficient for any household appliance. If you have a home that requires more than that, probably pay extra points is not a problem for you :).
The Baluns Passive Transceiver 4 Video Channels (CCTV) via Twisted Pair, 330m maximum They are totally passive, no need to feed them with electricity or any type of battery. In addition to the input / RJ45 and BNC outputs, there is a connector that accepts the wires directly. I did not use, but may be useful for those who want not use RJ45 plugs (connect the twisted pair cable directly) or want to cannibalize an RCA cable for failing to use BNC plugs. Not recommend such solutions, it is better to plug everything right. They can also be useful for those who want to use the surplus for other purposes pair.
Note that exist in specific baluns market for RCA cables, including specific baluns to transmit composite video signal and stereo audio, which is exactly what I needed, This would avoid the use of BNC to RCA adapters. The problem is that all I found were quite expensive. The Passive Balun Transceiver 4 Video Channels (CCTV) via Twisted Pair, 330m maximum of DX certainly is a much cheaper option and end up working the same way.
And I'm ending here the article about the two Baluns Passive Transceiver 4 Video Channels (CCTV) via Twisted Pair, 330m maximum (4-CH CCTV via Twisted Pair Passive Video Balun Transceiver (Max 330m)), with a positive rating.
