ONFIGURATION OF THE MODULE
Power to Trunk
The cascaded system is powered by the trunks, this means that the trunks power both the
cascaded Digital SCR Multiswitches as well as the LNB and trunk amplifiers. Trunk power can
be inserted at the "DC Input" of 1 or more cascaded units.
This allows an efficient sharing of the power from multiple units and creates a natural backup
system.
DC pass-through on the trunks is foreseen for the 4 Sat trunks only (Terrestrial is DC blocked).
Terrestrial path
The Terrestrial trunk is passive and DOCSIS signals can pass through in both directions.
The Terrestrial trunk should always be terminated with a 75-Ohm terminator.
