No converter in this case (in the cable that is). The cable has an RJ45 in one
end and a simple very thin USB-A in the other. Only wires inbetween.
There is probably a USB interface built into the UPS and wired out to the
RJ45...

But that is not a big problem, since when I plugged it into my Synology DS212j
it immediately recognized that there is an UPS and I could enable it in the
Synology system control panel. Including an UPS server function.

Now I am just scanning through the info I have dug up about connecting an Ubuntu
box to a networked UPS server (like the Synology).
Seems like it is not so complicated but enough so that I need to write notes to
myself...
