Output/Modulators - axing SKM 40-00M Betriebsanleitung

Operation instructions | SKM 40-00M | SKM 40-04M | SKM 80-00M
Direct connection to the LNBs
The devices have a remote supply voltage for the LNB and DiSEqC 1.0 functionalities at the inputs. The inputs
can be connected directly to the LNB.
Multiswitches as input distributors
Optionally, you can also use multiswitches as input distributors. The advantage of this solution is that you can
set both the polarization and the satellite via the user interface. Changes in the list of programmes can be
made using remote maintenance, so that it is not necessary to change or modify the input distribution on site.
Demodulation of the data stream
The selection of the frequency and the demodulation of the data stream are both done in the tuner.
If needed, the programmes from the data flow of the demodulated transponder can be filtered (Remux mode).
Thanks to the Cross Multiplex Mode, FTA programmes (Free to Air) can be filtered from the data flow of
several tuners for a common output channel and be bundled again.
The prepared data flow is passed on to the modulators.

Output/modulators

The output channels of the modulators are allways neighbour channels
The quattro devices have four output modulators and one RF output.
The first modulator can be set to any output channel. The other three modulators are automatically set by
incrementing the output channels in accordance with the chosen channel spacing.
For example: modulator 1
modulators 2, 3 and 4
The octo devices have eight output modulators. They are subdivided in two modulator groups of four
modulators each. The octo devices have two RF outputs (each for one modulator group).
In both groups, the first modulator can be set to any output channel. The next three modulators of both
modulator groups are automatically set by incrementing the output channels in accordance with the chosen
channel spacing.
For example: group A
group B
