sorry, i let this lapse, but for posterity...

turns out there wasn't a PMS-U10 at all here. The PMS interface was on CF in the CD-PVAA blade. so a bit of mucking around in 10-55 to assign it an IP then setting the license code and I could hit it from a browser. Not much you do in the interface itself except, of course tell it what language to speak...in this case set it to NEAX90 and all is well.
