Okay, what you need is a 'special' cable to connect 'pin x' at the UPS-port to some 'pin y' at the computers port. But the pins are very well described in the Owner's manual that comes with the UPS (or did they change their policy ?-- i bought my UPS in 1993). Are you sure that this is a Smart UPS 600 and not a Back UPS 600? Your description sounds like a Back UPS 600, from what I have read. According to this manual, there is a pin to turn off the UPS, one to signal a transfer to battery backup, one to signal if less than 2 minutes of backup time left (can be changed to 5 min) and one to turn on the UPS. This sounds very much like the Back-UPS product. I'll have more to say later this week when my unit shows up, assuming I have time to play with it and disaster doesn't strike. michaelkjohnson
