The network guy at the office gave me a APC Smart UPS 1000XLNET with some dead batteries. I replaced the batteries, that was no problem. I would like to find the cable I need to connect the UPS to the computer. The APC site has one, but it's $27.00 for a 6' cable. It says a standard rs232 will not work. Does anyone know the type of cable I need, would Monoprice have one? What is so special about this cable? I have cable that came with my old Cyberpower 1250avr but if I plug it in the APC shuts down, so I'm guessing it won't work.
