To extend the frequency range to the 12 GHz range (high band) or for
reception from more than two satellites, additional control signals are
required for LNB actuation and signal selection.
The DiSEqC™ signal is responsible for this. This is a special
modulation of the existing 22 kHz signal.
DiSEqC™1 Setting
The requirement is that you have not made any changes in the

make an incorrect setting, you will see the message “Poor or no
signal”.
DiSEqC™2 Setting
With cascading switches, a total of 16 satellite positions can be saved
under the “DiSeqC 2” menu option. Horizontal/Vertical and High/Low
give a total of 256 possible settings.
These
settings should only be made and this kind of system only
set up by a
qualifi ed
engineer.

To date, the LNB supply voltage of 14/18 V and the 22 kHz signal
(superimposed on the LNB supply voltage) have been suffi cient for
signal selection for most applications. These four switching signals
allow you to switch between the horizontally and vertically polarised
signals and between two satellites (multi-feed reception).
