The four trunks are DC isolated
from each other, so 13 V and 18 V
can be supplied separately from
trunk out to trunk in.
All 4 LNB trunks should always be
cascaded or terminated with a DC-
blocked 75-Ohm terminator. All
unused SCR/Legacy outputs should
be terminated with a 75-Ohm
terminator for proper terrestrial
signals.
In this example 1 multiswitch is
installed per floor. Only 2 power
supplies are used to power the 4
multiswitches.
