This menu is divided in two sections, the APC UPS Status table and APC UPS Response strings. UPS monitoring is only available for APC uninterruptible power supplies with USB connection compatible with APC’s smart protocol library. The UPS Monitor library is included by default only in the Mega-VPN and AIO builds.
For more details, see: https://networkupstools.org/protocols/apcsmart.html
To establish a successful connection, first enable USB 1.1 support (OHCI) and enable the Run APCUPSD Daemon in the USB Support menu.
This section contains a table displaying the UPS model name, status, charge level, line voltage, load, and estimated run time.
The list of strings has all the information retrieved from UPS.
This information is the same as in other tools (e.g. apcupsd utility daemon for controlling APC UPSes on a local network windows machine, http://www.apcupsd.org/)
