I can't install UPS

I installed NT 4.0 and I don't have UPS icon in Control Panel. I can't set UPS parameters. I installed Powerchute Plus program from APC (my UPS mark) but after booting i receive (in event log) warning saying "Unable to communicate with UPS". UPS should be ok, because it already worked with Netware 3.12.

The icon will only disappear when the service is not installed or not running correctly. Try reinstalling NT from your emergency disks. Failing this reinstall the software for your UPS software. If no go to control panel ->services and add the service there.

I've already tried to reinstall Win NT. It doesn't work either. There is no place during installation where I can set that I'll use UPS. By the way, service "UPS" has already been started but is  not working correctly because "Unable to communicate with UPS". What is wrong? Cable ?  Does APC UPS need special cable for NT?

APC UPS does not need a special cable. all you need is normaly shipped with the device.

important is that no UPS is enabled from NT site. (but installed)
then install PowerChute as last (after all other Software)
Check for disabling of all drivers that are using or testing serial ports (like serial logitech mice) on the port you have connected to APC UPS. then start PowerChute first time and configure communications port. the communication must be established within the same moment. (max 30 sec)
