Abstract
A method and apparatus for energizing a multi-channel LNBF containing multiple LNB(s) the LNBF connected to multiple IRDs. The number of IRDs present is detected. If more than one IRD is present, all LNBs are energized. If only one IRD is detected, power sufficient to supply the LNB the IRD has selected is supplied. Identification of which LNB the single IRD has selected may be determined by monitoring the presence of a desired voltage, frequency tone, and or series of frequency tones.
