Very interesting! Is this a production unit or still some kind of prototype? Has it a MPN of NW280AA or something else? Do you still know the original firmware version?

No, afraid not. I've upgraded the firmware as they've been released and I don't have a record of what it originally was.

This is very interesting as well. Again, is your device a production unit or a prototype?

I knew that there was a StreamSmart 400 (F2235AA) around 2008 and that there is a StreamSmart 410 (NW278AA) since about 2012, but I wasn't aware of the fact that there are two variants of the latter.

It comes in a case complete with probes, cables etc and an HP39gs, that is branded Fourier, so I think it is a kit that they sold for schools.

Quote:From what I was able to find out so far, the SS400 was designed by HP and is supposed to be compatible with the 39gs (with unknown firmware), 40gs (with unknown firmware) and 50g (with firmware 2.15 only), whereas the SS410 was designed by some Fourier contractor and is (or was at some point in time) supposed to be compatible with the HP 39gs (with unknown firmware), 40gs (with unknown firmware), 39gII (with firmware 1.3?), 50g (with firmware 2.16 only) and Prime (with firmware 6031 and higher). There's a lot of misleading or contradictory information floating around about these devices, and I have yet to see a user clearly stating that s/he was able to use one of them successfully on anything but a Prime. (This is what kept me from buying one for use with a 50g so far.)
