Ah, that makes sense now. I had initially thought red might have meant
something like "not working" or "poorly supported".

I was a bit worried when I could find very little about JBus outside the
world of Socomec other than that it was, as you say, a variant of Modbus.

I am looking for a UPS to cater for a rack of servers that collectively
may draw up to 2kVA. To allow for decent headroom (and usually
accompanied with higher battery capacity) I would favour a 3kVA UPS.
Due to the power in our building being somewhat "dirty" due to motors,
fluorescent lights, etc, some kind of line conditioning is required,
either through a full "online" UPS or active filtering, preferably the
The rack will be populated predominantly with Linux servers, and I want
to be able to use one of these to query the UPS about its status
(battery charge, load, etc). Once I have that I can integrate it via
bash scripts into an automated warning system.
