Looking for pinout/wiring of the APC 940-0273A RJ(45?50?) to USB cable used in some SmartUPS units.
Does anyone have this?
(APC = American Power Conversion, a Schneider Electric brand; UPS = Uninterruptible Power Supply == computer battery backup)
May be this one http://pinoutsguide.com/UPS/apc_usb_cable_pinout.shtml ?
Thanks, but I already found that. It says:
APC part# 940-0127B, 940-127C and 940-0127E
APC says I need a 940-0273A. Whether that has the same pinout for USB as the 0127 cables is unknown.
I believe that they multiplex a serial (rs232-e) port on the RJ end, so there's no guarantee that the USB wires come from the same pins on that end. (Obviously, the USB end is standardized.)
