MULTI-SATELLITE RECEPTION
______________________________________________________
LNC triggering with ToneBurst (also Mini-DiSEqC)
When LNC arrangement 3 is set, a so-called ToneBurst (Mini-DiSEqC ) signal will be emitted.
This contains the choice of satellite (A/B). This means you can also use the ToneBurst (Mini-DiSEqC )
switch to switch between the associated LNCs.
If the upper frequency range is chosen, the static
22 kHz signal will be emitted in addition to the
ToneBurst (Mini-DiSEqC ) signal.
This will enable you to receive and set the ~upper and –lower frequency range of two satellites if
you install two universal LNCs.
Instead of two universal LNCs, you can also connect two 22 kHz relays at the outputs of the
ToneBurst (Mini-DiSEqC ) switch.
This will enable you to connect up to four single LNCs to receive signals from four different satellites.
See also page 40, LNC arrangement 3.
Note:
When setting LNC arrangements 4 to 6, the ToneBurst (Mini-DiSEqC) signal is also emitted after
the DiSEqC 1.0 signal.
However, the shortest switching time for ToneBurst (Mini-DiSEqC ) is achieved in LNC arrangement 3.
