Hi I am planning on purchasing this adapter to hook up my Quadra 610 which has an aaui port to a modern ethernet cable (airport express). I just wanted to make sure that this one would work because I have seen different ones that say like "rj45" and "10 base t" etc. Hoping someone could assure me that this is indeed the correct type of adapter that I need.
