What does DiSEqC mean?
Tone Burst signal (also called Mini-DiSEqC signal)
is emitted. This signal comprises the satellite selec-
tion (A/B). A Tone Burst (mini-DiSEqC) switch can
therefore also be used to switch between the assig-
ned LNC's.
If the upper frequency range is selected, the static

The DiSEqC protocol comprises the following pos-
sibilities:
– Polarization H or V.
– Selection between lower and upper frequency
~
range (– or
).
The symbol "–" means the reception of the lower
~
frequency range of a satellite. The symbol "
"
means the reception of the upper frequency
range.
– Selection between up to 4 satellites (A/B/C/D).
You can therefore receive the lower and upper
~
frequency range of up to 4 satellites (– or
swit-
ches between the frequency ranges, A/B/C/D bet-
ween the satellites).
The oscillator frequencies of the LNC's can be en-
tered in the „LNC settings" menu (see page 14).
These switching options are independent of each
other for each of the two tuners A and B connec-
tions.
If the aerial system is accordingly equipped, it is
therefore possible to receive with each tuner
connection the lower and upper frequency range of
up to 4 satellites.

To receive with DiSEqC on one tuner connection the
signals of two satellites, select the LNC arrange-
ment 4 in the "LNC SETUP" menu (5 or 6, if neces-
sary).
