Electrical Interfaces
RF Inputs
The features four RF interfaces for applications in which more than one satellite
input is required. The ‘live’ input is software-selectable amongst these interfaces. Each
interface receives L-band satellite input through a 75-Ohm F-type female connector.
Additionally these RF interfaces can also provide voltage for Low Noise Block (LNB) down
converter power and control.
CAUTION In applications requiring the to supply LNB power an
additional 1-slot filler plate must be installed immediately to the right of the
to accommodate power requirements.
ASI In
This interface allows demultiplexing and decryption of a transport stream originating on
external equipment.
This ASI connections require 75-Ohm characteristic impedance coaxial cable. In general,
reliable operation can be achieved with cable lengths of up to 100 meters.
ASI Out
These interfaces provide duplicate copies of the demodulated signal received on the
configured L-band input, or of the signal received on the ASI input, decrypted and
demultiplexed according to the module's configuration.
All ASI connections require 75-Ohm characteristic impedance coaxial cable. In general,
reliable operation can be achieved with cable lengths of up to 100 meters.
