B.2.2.2 LNB Power and Control
The RX8000 supports voltage controlled LNBs only. The active input is selectable
and can provide DC power and frequency band selection signals compatible with
most professional and commercial LNBs. The LNB power is made available on only
one of its L-band inputs (F-type connector) and its power characteristics comply with
IEC 1319-1 and are as per Table B.24.
