3. TT1200 Output and connector description
3.1 1
st
IF
The 1
st
IF input is a 75 Ohm F connector. The demodulator takes both Ku-band and C-band, and has an
input frequency range from 950MHz to 2150MHz (true or inverted spectrum). The symbol rate range is
from 2Mbaud to 30.5Mbaud.
3.2 Conditional Access Smart Card Interface
In order to support different encryptions of MPEG streams, conditional access is implemented to be
able to decrypt the streams in the decoder. However, the implementation and solution varies between
the different Conditional Access vendors.
Generally, in order to support Conditional Access in any system, the PSI option in the decoder have to
be enabled. This makes the decoder able to receive the data streams which carries the information that
makes the decryption possible.
On T1200 hardware version B1 and higher, there are two slots for smart card readers. Which one to use
depends on what CA system is used, please refer to Figure 4. Note that in the case of Irdeto CA, an
additional CAM interface module and Irdeto PCMCIA CAM module must be installed.
3.2.1 Viaccess, Conax, Madiaguard and Nagravision CA versions
The system is based on using a smart card in the
smart card reader at the bottom right. The smart
card is to be inserted with the “micro-chip-side”
pointing upwards in the smart card slot, as shown
in Figure 5.
In these versions of TT1200, there is a blind plate
over the Irdeto CA smart card reader.
