* The unit's consumption with CAM will depend on the type of CAM being used. For the LNB it is considered a standard consumption of 300 mA.
The technical characteristics described are defi ned for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.

The DVBS2 transmodulator with COFDM CI receives a satellite transponder
in some DVBS (QPSK) or DVBS2 (QPSK or 8PSK) modulation formats and
demodulates it by obtaining an MPEG-2 transport package.
The MPEG2 transport package is then modulated in COFDM format and
converted to the output channel (UHF or VHF and with a maximum
bandwidth of 8 MHz) using an agile up-converter.
Additionally, it incorporates a Common Interface slot for inserting a
conditional access module (CAM) to permit the unscrambling of services.
The programming of the transmodulator operating parameters (input
frequency, output channel, modulation format and adaptation of services
mainly) is performed through the universal programmer (ref. 7234).
