Nut upsuser - May 2009 - Need help identifying UPS for use with NUT

Hi there.
I bought a generic UPS from a local (South African) hardware company,
Sahara.  They call it an "Electra 1000 Plus".  From what I am told it
is a
1000 VA line interactive UPS.  It comes with "WinPower" Java based
software
that I couldn't get to work. (Crashes on start-up, without any explanation.)

I would like to know if any one on this mailing list could help me to figure
out what NUT driver I am supposed to use.  I tried megatec, without success.
(/lib/nut/megatec -DDDD -a UPS1 returns with "Q1 => FAILED
[timeout]" 5
times ) A potential gotcha is that I am using a USB to serial device to talk
to the UPS.  It looks like it has installed correctly (dmesg tells me: "usb
2-1: ch341-uart converter now attached to ttyUSB0").  The USB-Serial
adapter
is connected to the serial cable that came with the UPS.

Some pictures of the UPS and parts of its manual can be found
here<http://picasaweb.google.com/diederikjhattingh/Public?feat=email#>(The
circuit board is just the switch.  I couldn't yet get to the serial
interface part of the UPS. Will still upload a picture of that when I get to
it.)

I am using Gentoo with NUT version 2.2.2

Any help would be appreciated.
Thanks

The last time I saw some Java software for a UPS it had its own JRE 
embedded.. they used a portable language in a very non portable way.

I seem to recall after some investigation it was actually megatec but I 
never had the opportunity to try NUT on it (it was in Indonesia and I 
am in Australia).

The megatec page does suggest you may need the dtr, rts & sendpace 
parameters before it will work.

just to complete Daniel's answer: whenever you see WinPower, try the megatec
drivers (serial or USB), or better, the new blazer ones. These are
Centralion rebranded units.

please report back the results of your testing.

cheers,
Arnaud
