Ok so I messed up and Lost the communications cable for my UPS. APC model BE500u. http://www.newegg.com/app/viewproductdesc.asp?description=42-101-128&DEPA=1 The cable is actually an USB to RJ45 cable. Anyone have any ideas on how or where I can get a new one for CHEAP. Or any documentation on how to make my own would work too! Thanks in advance.
