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 @
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...
