I was dropping off junk at the waste transfer station and scarfed a UPS
out of the pile of old TV's and VCR's. It was in good physical condition
and as I expected, the battery was toast. A new RBC-2 battery restored
it to working condition. Then I tried to get it to talk to some
software. And I am having no luck.
The unit is branded as a Nexxtech Model 6118507 650VA imported into
Canada for Orbyx Electronics LLC. Nexxtech is a house brand for 'The
Source' ex-Radio Shack in Canada.
It has a red LCD display on the front and has the same physical layout
as some of the smaller APC BackUPS and CyberPower units. However trying
the powerpanel and APC specific drivers was fruitless.
The unit is 6" high x 4" wide by 12" deep. It has 3 UPS outlets plus 3
surge protected outlets and a USB port.
I am running Fedora 14 2.6.35.14-96.fc14.x86_64 with
nut-2.6.2-1.fc14.x86_64.rpm from the Fedora repo
I strongly suspect that this unit was made in China ( by MEC??) and
branded in various different ways (the 'Fry's Electronics' report is a
but of a giveaway! especially as there are no Fry's in Canada). A thread
on this list from 2006 had the same reported data Vendor/Product id but
a different branding. Unfortunately that thread had no resolution.
Due to the fact that this unit does not seem to report itself correctly
there is a possibility that it cannot be made 'intelligent'. But I'd
like to try, first.
I have installed nut and done the usual things. The unit is almost
'there', but not quite. I have trolled through the FAQ and the list but
nothing (except that one thread) seem to deal with this.

Check on the install by restarting the daemon:
It's all down to the driver.

I have NO idea why the Device does not match... but then I am not sure
what is is attempting to match. The installation is fine: upsd reports
periodically that it cannot communicate with the unit..
So what is the driver trying to match against? And can I amend any
settings to make it match? Can I provide any more info.
