This man page only documents the hardware-specific features of the
belkin driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
The belkin driver is known to support the Regulator Pro 525 (F6C525-SER).
Other similar models such as the 425 and 625 should also work.
The Trust UPS and older Belkin units are not supported.
EXTRA ARGUMENTS
This driver does not support any extra values for -x or in the ups.conf.
BUGS
The protocol for this UPS is not officially documented.
Beware. It is possible to turn your UPS into a glorified power strip if
you play with the protocol directly. In particular, there is one command
that will convince it that it has no batteries, so you lose your
protection.
I had to go out and buy another identical model to find out what to
program back into that register to bring the first one back to life.
It is not safe to send random characters to this UPS.
