if you don't want to make your own cable you can use the blue cisco-console-cable. you must only cut the rj45, take a new one but spin it befor crimping.
Another way is to use the old cisco-console-adapter but with a 1:1 cable
If you use the DB9 rj45 Cisco terminal Adapter, open it and cut the red cable. If you don't cut the red cable, the CS can reboot when you plug on the console port.
