The boolean variables seem to be indicated by "Yes". I think the "meter map" is the source of the numeric variables:

   0.566550	Index	Offset	Format	NUT
   0.566617	0027	0000	51	output.frequency
   0.566680	0028	0004	51	input.frequency

   0.566805	0041	0012	f0	battery.voltage.low
   0.566866	0043	0016	f0	battery.charge.low
   0.566928	0047	0020	f0	ups.load
   0.566989	0056	0024	f0	input.voltage
   0.567051	0065	0028	51	output.current
   0.567113	0068	0032	51	output.current.nominal
   0.567175	0078	0036	f0	output.voltage
   0.567237	0091	0040	f0	input.quality

Maybe Alf has some additional insights?

I think Settings are what you would see from "upsrw <ups>", and Commands are listed by "upscmd -l <ups>". You're going to make me actually install the CGI programs, aren't you? Everything else I have been able to just look up in the source :-)

(The Belkin is two 12v batteries, the Eaton is one.) Anyway, the driver for the Belkin actually has Settings reported, and I can't remember, but about 10+ different Commands.

Right, or that the protocol doesn't expose the settings or commands.

> p.s. The only difference I can see from the web page any my upsc output is that my UPS is a 700, and the driver was developed on a 500?

The part that confuses me is why they would have the same firmware revision for what seem to be different sets of capabilities. Usually, the only internal difference between a 500 VA UPS and a 700 VA UPS is the size of the battery string and maybe the power electronics module.
