Hi Guys
I can't make this working i hope you can help...
Since here in Benelux the RJ50 plugs is impossible to find i decided to open up the UPS and solder directly on my 550 motherboard.
I found different pinouts though:
APC BackUPS CS/ES smart signalling cable распиновка и описание @ pinouts.ru APC USB cable AP9827 : Pinout cable and connector diagrams-usb, serial rs232,rj45 ethernet, vga, parallel, atx, dvi...
I tried the first one and is not working...and i am not too sure about the pinout it looks like 1 and 10 pins are not correct...
Anyone can tell me where PIN 1 is on the Rj50 and where the 4 USB wires need to go?
Without USB the UPS is pretty useless to me...
