Hi Spike, sorry for the lag in answering, I was collecting the needed information. I have a eaton 1500 that connects to an Ubuntu Xenial box via USB.

As far as I've been told, when there is an actual SW communication (such as with NUT) with requests and replies in the 5mn timeframe, this should not occur. Could you please: - confirm back that there is indeed a SW communication setup (NUT or UPower for example), - send me back the upsc output for this unit, including the serial number and firmware revision thanks and regards, Arno -- Eaton Data Center Automation Solutions - Opensource Leader - http://42ity.org NUT (Network UPS Tools) Project Leader - http://www.networkupstools.org Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.fr
