Radius TPD SE/30 cable components
Posted by: TimHD on 2016-03-25 02:37:21
Does anyone have a spare one of the internal cables for these radius Two Page Display (TPD) cards?

Alternatively do you know what kind of connectors and cabling are being used in the adapter cable?

Seems to be a standard BNC (75 or 50 ohm?) attached to rear slot and a smaller kind of mini BNC? connector (5mm?) attaching onto the video card itself.

Trying to recreate the cable to test the card out...

That looks a lot like a standard cable used in radio stuff. If I am right, uniserver probably knows for sure. He is really good with radio stuff.

I have seen cables that look like this with my friends HAM radio gear.  You might try a Radio Shack (if they have not all closed) near you.

I'd assume that if you can find the appropriate connector for the smaller BNC, you can wire up a cable with the standard sized BNC on the other end.  There's only one signal line on those (like composite TV video, carrying pixel data and sync on the same line), the inner conductor, with the shield being ground.

Thanks all.

Does anyone know what the smaller connector is called? (So I can order a connector that works with it)

The male/female bnc that goes on the back plate is standard (so easy to buy) but not sure how to describe / find the smaller one. It measures 8mm in diameter and looks like a male (has single wire in the centre) plug that goes into a standard female BNC connector - just without the outer sheath that locks onto the little bars you see coming out of std connectors like old network connectors.

Maybe it's just needs a simple female connector without the lock mechanism you see on BNC adapters used externally (and hence at risk of falling off).

Don't suppose you have a female BNC around to test-fit or hack up?

Hi, just coming back to this as I have a Radius Monitor inbound and would like to get this radius connector cloned so I can use it...

As before, here's my Radius SE/30 TPD album, now including some close ups of the Radius proprietary connector I am trying to clone. The BNC end is easy, the bit that connects to the TPD Card is the tricky bit...

Anyone know what the plug is? Looks like I might have to just buy a few and try, so welcome any links or descriptions I can use to find something close to it to try with...

NB: The internal connector is the same width/diameter as the external BNC female connector.

Replace the Board's funky connector with generic F-Type? Run that to a coupler on the backplane and make up an F-Connector/CO-AX to BNC for monitor connection?

I'm dying to see if one of those Radius cards will work on one of the 5 BNC inputs of my Radius PrecisionView 2150. Alas, can't find the VidCard, just the MagicBus Adapter,don't have an SE and I'm actually not quite dying to give it a go. Not to the tune of having yet another Compact in the menagerie.
