Introduction: APC UPS RS 1000 USB Conversion
Hi all,
I have just been given an Uninteruptable Power Supply. Great! One drawback, no cables!
It needed:
1 x USB to RJ50 cable
RJ50 cables look like normal ethernet RJ45 cables but have 10 pins not 8.
At least 1 kettle lead with a male connection one end and a female connection the other.
I looked at making a cable, but i would need an RJ50 plug. That wouldn't do! I will replace the socket instead.

Step 1: Popping It Open
I popped it open to see if adding/replacing the data port was a viable option.
Step 2: Removing the Rear Facia
Step 3: Cable Layout
Step 4: No Idea What This Port Is For, But Thr RJ50 Socket at the Bottom in Black
Step 5: The Board Completely Removed
Step 6: Underside of Board Where the Socket Is Soldered In
