This man page only documents the hardware-specific features of the belkin driver. For information about the core driver, see nutupsdrv(8).
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.
This driver does not support any extra settings in the ups.conf(5).
There are dragons lurking within the protocol to this UPS. I have one that essentially behaves like a glorified power strip due to some invasive probing on my part. Don't mess with it directly.
the driver doesn't go anywhere near these character sequences, so it won't zap your UPS. I only mention this here as yet another reminder of the perils of closed hardware.
