When I installed my PK Electronics 'BlackoutBuster' 500VA with
a serial port input (which is on COM2 on my computer), neither of the two
packages that PK Electronics supplied worked very well with Windows 2000.
I finally uninstalled the third party software and just used the Windows
built-in U.P.S. configuration utility since my needs are pretty simple.
Start-Settings-Control Panel-Power Options-UPS-Select-Generic-COM port 2-
-Custom-Next and then set signal polarity.
You can configure it for elapsed time and/or serial inputs
