The cassette is equipped with two common interfaces. This allows you to con-
nect two CA modules for various scrambling systems and service providers.
Scrambled channels can only be descrambled with a CA module suitable for
the scrambling system and the corresponding smart card. The smart card con-
tains all the information for authorisation, descrambling and subscription.
– Check with the distributor or manufacturer of the CA modules to be used
to ensure that they are suitable for descrambling several channels.
– The hardware and software of this cassette have been thoroughly prepared
and tested.
– Any changes made by programme provider to the structures in the pro-
gramme data might impair or even prevent this function.
– When working with the CA modules, please read the corresponding oper-
ating manuals from the respective providers.
