Vga a rca

The basic idea behind the cable is to use a CAT5 or CAT5e computer cable to carry the video signal. The cable is pretty easy to make if you have some basic soldering skills. Works for distances up to 50'. Full credit for this idea goes to MrWigggles on AVSforum, in this thread. A couple of assumptions here, the projector has a 15 pin VGA style video port on it. If it has 5 BNC connectors instead,then the recipe changes a bit. You must use three pairs for R, G & B, and split the fourth pair for H&V, each connected to a BNC. I've attached a picture of a VGA connector. You will need two male connectors with hoods. I recommend the metal hoods. You can get them at Radio Shack or any decent electronics parts store. You will also need a length of CAT5 or CAT5e cable. The shielded variety (STP)is supposed to work better than the unshielded (UTP) but the UTP is much more common. I used UTP and got good results. Here are the pin outs. A CAT5 cable has 8 conductors in 4 color coded pairs. The ground connections are all common and the DDC DAT is for plug and play detection and likely won't work with your projector any way. I've added what CAT5 conductors I used for what pins in the tablebelow. The same connections on both ends. VGA Video connector pinouts: Pin # - Signal Name - CAT 5 Conductor 1 - Red - Orange 2 - Green - Green 3 - Blue - Blue 4 - No Connection 5 - Ground - No Connection 6 - Ground - Orange/White 7 - Ground - Green/White 8 - Ground - Blue/White 9 - No Connection 10 - Ground - No Connection 11 - No Connect 12 - DDC DAT - No Connection 13 - Horizontal Synchronization- Brown 14 - Vertical Synchronization - Brown White 15 - DDC Clock - No Connection I recommend checking all of your connections, from pin to pin, for continuity with a multimeter. You may need to use a short piece of wire (a strand from the CAT 5 cable will work) to reach into the pin sockets. VGA (HD15) Connection Pins

This method can also be used to make a good component cable can be madefrom CAT5. I had someone ask me if it would work. I thought is should work great, so I made a 50 foot cable and it

did! The person who asked about it is now using the 50’ CAT5 Component cable with his Infocus X1 DLP projector. Just use three of the four pairs, one each, for Y, Pr, and Pb. Untwist the pairs as little as possible and solder on an RCA connector to each end, one conductor to thecenter pin and the other to the shell. I added some shrink tubing to the pairs to give it some extra strength, but this is not required. Total cost was about $10, with the cable from Lowe’s and the RCA connectors from Radio Shack. Useful link: Video over UTP from Extron. To interface to the 9-pin RGB Port 3 on a Barco CRT projector, use these pin-outs. The diagram below shows the how to use thismethod to make a VGA (HD-15 connector) to component breakout cable. This cable is used to connect a component video source such as a DVD player or Satellite/Cable receiver to a projector, RPTV, LCD or Plasma that accepts componet video via an HD-15 port. In some models, you will have to set this input to "component" via the menu system, others will auto-sense the input.

I used parts from Radio Shack, although these parts should be available at most any electronics supply house. The cable is available from most home improvementstores. The Radio Shack part numbers I used are: 276-1508 Metal Hood, 276-1502 15 Pin D-Sub, Female, 276-1501 15 Pin D-Sub, male 274-319 RCA Plug, 4-Pack Will I be able to use the VGA to component adapter to watch DVD's from my DVD player on my computer monitor? Probably not, the adapter just "adapts" it doesn't convert. Nearly all computer monitors need an RGB signal, as compared to the...
