I have UPS from Fairstone that I would like to connect to my FreeBSD machine at home.

The interface of the Ups is very simple and does only have ON/OFF signaling to inform the state of the UPS.

The interface port pinout is :

pin 2 - AC failure (Normal Open) pin 3 - AC failure (Normal Close) pin 4 - Common pin 5 - Battery Low pin 6 - Remote shutdown pin 7 - Common

Do you know of any UPSd that support interface like this ?
