If you look around the Nut pages you will find a link to build a cable to work with the APC Backups series of units. I'm using the software with an APC smartups and a Upsonic PC might (contact closure) ups. The cable for the Smartups it a self built smart cable and the Upsonic has a custom built cable for the contact closure. One of the other nice things about Nut is that Netsaint and Nagios can monitor it for you. Joseph Key
