Jim,
I just tried both and they seem to work OK on my system.
I am using Win 7, a new set of Triumph-1Ms and a OLD set of Hipers (per GLONASS)
The JAVAD seemed to connect good after installing their drivers. I was still able to access my Hipers using TRU Ver 2.8 I use a quite old cable from my data collector, that goes from my Hiper barrel connector, to the 9 pin DC connector, which I then use a (iOGear I think) 9 pin to USB adapter.
I was able to download a static file from both brands successfully.
