Sweex is notorious for changing the internals of their devices at will.
In fact, they are just selling rebranded OEM equipment.

By the time we've figured that out, they have probably switched to
another supplier and yet another protocol. I doubt it's worth the effort.

No difference at all. It's a Chinese company and most likely they are
not willing to share details about the internals of their systems, for
fear of others copying it (which has probably happened by now anyway).
Don't bother.

I'm not and unless you're willing to take up the task yourself, I very
much doubt that anyone else here will. The track record of Sweex
regarding support of the UPS systems is appalling. If you want full *NIX
support for your UPS, you'd better switch to a supplier who really
develops their own systems and supports them properly (MGE for instance).
