Hi Gene,

a first thank to Greg and Roger for the much appreciated help on the
support queue...

first, this unit is known to work for more than 2 years.
next, as mentioned by Greg, is NUT configured?

the basic files needed for standalone protection are nut.conf, ups.conf,
upsd.{conf,users} and upsmon.conf
hosts.conf is for CGI operations...

There are some documentation, more Debian / Ubuntu focused, that may help

A note on USB device permissions: you need to have udev rules refreshed.
Depending on your system and package versions, you may have to issue:
* sudo udevadm trigger --subsystem-match=usb --action=change

and to unplug/replug your UPS USB cord.
Then start nut using "service nut start".
Before trying with NUT-Monitor, prefer using "upsc <devname>" with devname
from ups.conf
