Common Interface
Chapter 23
The instrument is equipped with a CI interface. This consists of a PCMCIA slot (see chapter 3.3 -
Top section of instrument). The PCMCIA slot is compatible with all common conditional access
modules (CAM). This means that all DVB channels can be decoded with an appropriate CA module
and activated smartcard. Data streams are exclusively decoded in the inserted CAM, not in the
MPEG decoder itself.
23.1
Inserting a CA module
The instrument must be switched off when a
CA module is inserted. Insert the module into
the port at the top section of the instrument.
When inserting the module, ensure that the
polarity is correct and that the barcode is
pointing
to the rear
. Do not force the module
into the slot if there is significant resistance.

Operation
The inserted module is initialized when the instrument is cold-started. Use the Common Interface
menu to query the inserted CA module. Enter
MODE
->
Common Interface
to access the menu.
The CA module name is shown as a menu title.
Use the first menu item (“CA-SystemIDs”) to query CA systems supported by the module. The next
section explains the second menu item (“Card Menu”). To check the picture and sound quality of
encoded channels, proceed as described in Chapter 12 - MPEG decoder.
