* Consumptions are measured with input signal.
The consumption indicated for CAM and LNB are highest; in any case, depend on the type of CAM and LNB for each facility.
The technical specifications are defined for an ambient temperature of 45 ° C (113 ° F). For higher temperatures forced ventilation will be used.

Introduction
The multiplexor receives a satellite transponder in any of DVBS (QPSK) or
DVBS2 (QPSK or 8PSK) modulation formats, and demodulates it to obtain a
transport stream packet.
Then, the transport stream packet is modulated, either in QAM format (Ref.
564101) or COFDM format (564201), and converted to the output channel by
means of an agile up-converter.
Additionally, it incorporates a Common Interface slot for inserting a
conditional access module (CAM) that permits the unscrambling of services.
To configure the multiplexer operating parameters (input frequency, output
channel, modulation format and adaptation of services mainly) can be used
the universal programming unit (ref. 7234) or the TSuite software.
