Long VGA BNC Cable in wall with loose BNC connector
Hi,
We've recently moved into a condo that has a long VGA-BNC cable wired from a homerun location to our living room. The blue (not that it matters) BNC connector is loose so our VGA signal occassionally looses color. Replacing this cable isn't an option so I'd like to simply replace the BNC connector. I assume this involves somehow stripping the cable and clamping on a new BNC connector. The outer diameter of the blue cable/wire is on the order of 3/32". Knowing nothing about hardware (hey, I'm a software guy :-), I don't know whether there is a wire under the insulation that needs to be stripped or a coax type wire that needs a more sophisticated tool to strip it. Also, is there a standard size for the wire end of the BNC connector? Any pointers in the correct direction for solving this problem would be appreciated. Clearly, if this wasn't embedded in our wall, I would just buy a new cable. Thanks, arn |

Jonesy,
Thanks for your reply and sorry if I'm being dense but would a vga breakout cable have the individual lines (r,g,b,h,v) as coax? That is really my question. It seems awfully thin. In any event, google has not been helpful in understanding what is going on here. I've tried. It isn't just a termination question but understanding what the make-up of these standard cables is. James, NSM The problem is definitely in the connector. If I wiggle the blue BNC connector, there isn't a problem. I can also put a probe on both ends (attached with a long wire) and see there isn't a continuity problem in the wire itself. Again, any help would be appreciated. |

Sorry, you have multiple BNCs? That wasn't clear to me. In that case, yes, I would expect each to be a separate coax. You can solder or crimp the center pin on. The shield is usually captured by the connector. N |

Either way he said wiggling the connector effects this, so I'd say it's pretty obvious the problem is in that area. I'm using a 25' KVM (Belkin) cable alleged to support XGA right now.

The shield is usually captured by the connector. Yes, it was not clear to me that there were 3 lines, either. Ok, three separate RG-62 (?) lines terminated with BNC connectors would no doubt be the "individual lines (r,g,b...". Probably (somewhere buried in the wall) there is a break-out of the RGB lines in the VGA cable and the long run(s) completed with RG-62 (? 92 ohm -- probably not RG-59 or RG-58) to provide decent video "at a distance."
