I trying to connect RB2011UAS-2HnD-IN and APC Smart-UPS CS 420.
I have a Cisco Roll Over Cable RJ-45 - DB9F.
What pinouts to make a Cable like RJ-45 - DB9M? Or to make a adapter DB9M-DB9M with original Cisco Roll Over Cable RJ-45 DB9F?
I’m currently to get an APC USB UPS working together with an RB2011. The same UPS works like a charme with the same cable connected to a RB411. I think it might not be the cable, but the RB2011 that is causing the problem. Only just a guess!
