[Nut-upsuser] CyberPower CP550SL / AE550 success

[Jonathan A. Kollasch]

Hi,

I finally got the serial cable for this
CyberPower CP550SL / AE550, and have
successfully tested the genericups type
7 driver.

The shutdown delay is about 2 minutes
after the shutdown signal, and that
signal needs to be rather long, I got
it to work with 20 seconds.

I suspect that all CyberPower UPSes
that are compatible with the Windows
UPS service are type 7.  All references
to the Windows UPS service that I've
found on their web site specify the same
configuration polarities.  These
parameters coincide with the (undocumented)
Windows UPS service pin-out and genericups
type 7 uses this pin-out and
CyberPower's signal polarities.

I've also found that it will work with
the newhidups driver in trunk, but
that's not quite as useful to me as it
requires a non-GENERIC NetBSD kernel.

I suggest adding this to the list
of compatible hardware.
