	[[User:Malcolm.chambers\|Malcolm.chambers]] 20:57, 1 January 2010 (UTC) The powered cat5 adapters are certainly different and the right one must be at each end. HOWEVER, I don't see why the bodged BNC to VGA adapters should be different, surely the same pin is used at both ends of a VGA cable for each colour. Having made the claim that they're identical, problems (IE none of the three video signals reaching their destination) were experienced at Woodstock 2009, and if the BNC to VGA bodges are indeed different then this could be the source of the problem.

			[[User:Michael.Cullen\|Michael.Cullen]] 22:59, 11 January 2010 (UTC) Not wanting to turn this into a conversation, I think that the difference is that one has a male VGA on the other has female. You can actually connect them together and run a video signal through it. The upside of this is that if there are any other differences, the connectors prevent this from causing problems. Woodstock suffered bad cat5 runs - it worked over a short cable (well, one of the BNCs did...)

			Rextron part number EVA214, consists of a transmitter (part no. EVA12L, serial number V37034HG00065) and receiver (part no. EVA02R, serial number V35034HG00065) which are linked using any convenient CAT-5 network cable. You can then put a VGA video signal plus mono audio into the transmitter, and get them back out of the receiver. Also has built-in DAs at both ends, so each box has two independent outputs, as well as the CAT-5 output from the transmitter.

	This was an inspired confection first developed to overcome a lack of long video cables at Woodstock 2007, but offering some very nice advantages for the future. The starting point was the availability of the pair of boxes for sending VGA analogue PC video over a CAT5 network cable. These commercial adaptors provide a neat, practical solution to the impedance matching and balancing required to send the component video and sync signals of a standard VGA signal over the 110R twisted pairs of CAT5 cable.
