[Nut-upsuser] Problem to connect to APC SC1500

[Michael Apelt]

Hello,

I am not able to get NUT working with a APC SC1500.

The ups has only a serial port and came with a 940-0272a serial to usb cable. The cable has a fake Prolific chip in it, so only works by downgrading the driver to version 3.2. I tested a 940-0024C cable without success as well.
The ups works with powerchute and apcupsd with the 940-0272a cable. Have not tested it with the other one.

OS: Windows Server 2012 R2
NUT-Version: Windows-v2.6.5-6
UPS: APC SC 1500VA
Driver: apcsmart

upsdrvctl.exe start outputs this errors:

I thought about using apcupsd-ups driver, but that one is not included in the Windows installation of NUT.

What am I missing here?
