a friend gave me an old apc smart-ups 1250
it has a rs232 interface but i have no pc with a rs232 port
i attempted to use a rs232 to usb adapter but the ups goes nuts
i connected the ups to batteries and verified it was working properly
when i plug the usb cable into the pc the ups shuts down
when i attempt to turn it on it beeps twice and shuts down
this all occurs before i start the nut software
other than give up or buy a new ups, any suggestions
Far cheaper than a new UPS would be a 2nd hand old small PC with ethernet;
then run NUT over ethernet to modern PC
he would still need a correct cable ( as required by APC, I forgot about
their brain dead decision to use non standard wiring ), which seems to
be his real problem. and cheaper and consuming much less energy than any
old pc is a pci rs232 adapter
