Hi List,

i've installed the network ups tool on one of my windows machine (server
2012 r2).
My ups is an APC Back-UPS Pro 550 which is connected via USB to an Synology
Diskstation DS414.

I found this video https://www.youtube.com/watch?v=0l54n_37M_k

My config:


driver = snmp-ups
port =
community = public


password = secret
actions = SET
instcmds = ALL
upsmon slave

MONITOR ups at localhost 1 monuser secret

After i've started the service, my eventlog show me this error:
(Application Error - EventID 1000)

Faulting application name :snmp-ups.exe, version:, time stamp:

Please report it to NUT developers, with an 'upsc' output for your device.
Going back to the classic MIB detection method.

=> Same error and entry in eventlog

Any idea how to fix this and get the things work?
