CI Interface

[rolf@max.lui.uni-tuebingen.de]

Hello!

My CI Interface card has a 3.5mm Connector
but i doubt that its another Audio-Out.
I heared that it may be a IR reciever connector.
What could that thing be really?

I also want to buy a CAM Module but 
there are so many.

Irdeto All-CAM
Irdeto CI-All-CAM
Irdeto CI-CAM
ALL-CAM SE
etc.

Do they all work?
Or do i need a special one?
 
Any Hints? Thanks in Advance!

greetings
         Rolf
