. The slots and openings in the cabinet and in the back or bottom are provided for necessary ventilation. To ensure reliable operation of this apparatus and to protect it from overheating, these slots and openings must never be blocked or covered. From Wikipedia: 'The Common Interface (CI) is the slot on a digital television receiver into which a conditional access module (CAM) may be inserted for satellite television. Receivers normally have two common interfaces.

Note that not all transmissions have a CAM available, Spains Digital+ for example uses the Nagravision 3 encryption or the SECA encryption, there are yet no Nagra3 CAMs available, so the original D+ set top box has to be used. ( SECA is available )

Fransat Cards do work in the right cam, they have changed the standard now to CI+. However our tests on various receivers have come up with no compatible model ! The cam can be used in a TV with a satellite tuner, as long as the interface in the tv is version CI+ 1.3

What is CI+

CI Plus: This a new addition to the specification of the standard unit. It is an improvement on the electronics of the CI standard as far as video piracy is concerned.. The CI Plus interface is required to be able to use CI Plus modules for the cable network or other pay TV providers . They can be used independently to decode encrypted channels or more commonly used together with a SmartCard. The main difference and the reason for its introduction is it is now possible for broadcasters to impose restrictions for the recording of programmes. In doing so, the recorded encrypted signal is scrambled on the screen if the restriction is active.. Recordings will therefore have a limited time, if the broadcaster applies this, after which they will not be viewable.

The CI Plus interface is also backwards compatible with old Common Interfaces (CI) and can also accommodate modules of this type.

This command will tune the satellite DVB-S2 transponder 12303MHz 27500H on Eutelsat 36B satellite. This transponder broadcasts encrypted content for largest Russian satellite TV operator “Tricolor TV”. I’m using Neotion DRE Pro CAM and smart card officially ordered from Tricolor TV. If everything is ok you should see decrypted content in the out.ts file. Here is the correct output for the above mentioned command:
