In TT1200 versions with Irdeto CA an additional CAM interface module is used, on which an Irdeto
CAM module may be inserted. The Irdeto descrambling is done in this module. In this case
CA-mode
is set to
AUX module
. Furthermore, since the descrambled signal from the CA-module is the input to
the demux/decoding chips,
Input source
is set to
AUX
.
These parameters are preset from the factory, and should not be changed.
