I have been finding video clips around the internet promoting the NIPROS PS-270 studio adapter for the EX3 but I have not been able to find any mention of it outside of this and a few short articles.

Sony's web site has no mention of the unit although Google has links to non-functioning pages on Sony's server.

Does anyone have a link to technical specs for the adapter or an operating manual? Is this a Sony product or is it from an outside company like the HD fiber adapters for Sony's high end HD cameras?

I think this is the only sony page with info:
Sony Product Detail Page - PMWEX3NPAC (http://pro.sony.com/bbsc/ssr/product-PMWEX3NPAC/)

I thought I'd seen a pdf floating around, but can't find it right now. I went to a demo and they had a handout, so perhaps I'm confusing reality and the internet again...

Thanks, it looks like they are nowhere close to finishing the pages. A lot of information is missing or left blank.

As far as I know it is not a Sony product but a third party unit.
