Hello,
I have an APC Back-UPS ES USB 650VA, but I do not have the RJ-45 to USB cable that is required to connect it to a computer. Could someone who has one of these test their cable? I have been playing around with a multimeter on a standard Cat5 cable connected to it, but haven't found out anything. Does anyone know what characteristics the correct pins would have (voltage, resistance, etc)?
--edit--
Oops... It seems that this is actually an RJ-50 like the one mentioned here (
