Connections Issue

post #1 of 5
Thread Starter 
Not sure if this is the right subforum or not.....

I'm about to hook up a new projector in our conference room at work.

The existing wiring into the housing area is OLD....as in, it terminates in a 5BNC Component video setup.

Every projector I can find that works with our setup (long, narrow room) has pretty much has a VGA input. I've seen cables that are listed as VGA to 5BNC converters, and they're listed as bidirectional, but I'm not sure how the whole setup would work (connecting the 2 5BNC ends together) to get it to output VGA.

ANY help would be greatly appreciated!

Thanks!

Edit: Can mods delete this. It's not a CRT projector...It's a digital projector. I posted the question in that forum instead.

Hi,

This is a little confusing - typically VGA is RGBHV which
is either on a Dsub 15 or Dsub9 or 5 BNC...and it
goes nicely with the RGBHV inputs on most CRT PJ's.

Component is Y, Pb, Pr which is only available as an
input on some Sony and NEC models, and is very rarely
found on a PC based source.

Since you have a conference room, perhaps you are using
a computer as a source? What type (brand/model#) of
CRT projector are you installing?

Here's how to solve this:

Get 5 female to female BNC couplers, and get a short SVGA to 5 BNC cable. Convert the BNC ends back to SVGA and connect that to any digital projector.

Computer is the source. But the existing wiring was run LONG ago, from about 20 feet away (where the PC is...at a podium), through the walls, back to where the OLD sony projector was. Back by the projector, it terminates in 5 BNC ends. I need to "convert" those 5 BNC ends to a D-Sub 15 male connection (or something else more "standard".

We've actually NOT purchased the projector yet...or rather, we purchased one and our supplier "substituted" one that simply won't work for our needs (30 ft long conference room with a 8 x 16-ish screen at the end) so it's going back. I THINK we're going to order the IN24 or IN26...but much of that depends on finding a way to convert the existing wiring to match what those projectors can handle or whether I'll have to have facilities come in and rewire.....Time being of the essense, I'd rather find a way to work with the existing wiring/terminations.

Thanks Curt. That's sort of what I figured but most of the cables I see list the conversion the other way, so I wasn't sure.

Like this one:

Do you know (I sent an email off to the company, too) if those types of cables are usually bi-directional?

Thanks everyone for the help. I'm a Systems Analyst kinda guy, with some "light" hardware knowledge....and a dabbling in more mundane A/V as a home hobby. This stuff is WAY outside my comfort zone.
