Fundamentals of the DiSEqC signal (Digital Satellite Equipment Control)
In order to select the satellite signals different control signals are required.
Up until now, the 14/18V LNB supply voltage and the 22 kHz signal (superimposed
on the LNB supply voltage) have been sufficient for signal selection for the majority
of applications.
With these four control criteria it is possible to switch between horizontally and ver-
tically polarised signals, as well as between two satellites (multifeed reception).
With the extension of the frequency range to the 12 GHz region (high-band region
11.70 – 12.75 GHz) or for reception of more than two satellites, additional control
criteria are required for LNB selection and signal selection.
The “DiSEqC“ control signal is, in fact, a special form of modulation (pulse-width
modulation) of the already existing 22 kHz signal.
The UFD 400 receiver is equipped with:
•
DiSEqC tone burst
(also termed Simple DiSEqC or just DiSEqC)
and
•
DiSEqC 1.1
The setting required is dependent on the components of your receiving system.
Setting options in the DiSEqC menu
•
Call the initial setup menu (see paragraph “Calling the initial setup menu“).
•
Using the
keys move to menu entry “DiSEqC menu . . .“.
•
Activate the submenu “DiSEqC menu . . .“.using the
keys
The following menu appears (factory preset):
Setting option:
22 kHz Signal: Off, High/Low, Pos A/B
Tone Burst: Off, Pos A/B, Opt A/B, High/Low
DiSEqC: Off, On
DiSEqC Repeat: Off, 1 or 2
UFO mini: Off, On, UFO twin 1, UFO twin 2
Remote Freq.: 0-2150 MHz
UFO micro: Off, On, Reset
The bottom line shows the keys you can use to make the settings.
22 kHz signal
In this menu entry, you specify whether the 22 kHz signal is to be used to switch
between a satellite‘s lower and upper frequency range (low/high) or to switch be-
tween two satellite positions (Pos. A/B).
