I have tested with instruments the pins on those cables and very little to nothing found in a way of a signal. If you go to that apcupsd URL and did down you will find all (most) of the cables and it also explains them. SmartUPSes -- yes -- okay and will work with the cable. The computer may sense the dumb UPS -- BUT, will not communicate about shutdown and other critical info. If I'm wrong, then let me know.... I spent a lot of time falling for the "cable" bit. Dumb UPSes are useful for keeping the machines going until you or a master machine can tell it to shut down gracefully.... Best regards, Jack L.
