I did investigate the pin-out after I bought mine; they seem to use
all pins and I seem to remember that a couple are looped back?
Anyway, they sure were nonstandard. They have different kinds of

Have you looked at the Network UPS Tools project?
http://www.exploits.org/nut/ has information about lots of UPS stuff,
