DiSEqC switches - multi satellite reception
Technical data on DiSEqC switches
DiSEqC switch
A DiSEqC switch is applied when using 2 universal LNBs. In principle, a DiSEqC
switch works as a tone-switch, but if you connect a universal LNB, 22 kHz tone is
used for switching between 9.75 and 10.6 MHz.
Priority switch
This switch connects two satellite receivers with one or more LNBs. It may be a system
with an analog and a digital receiver, or a Pal and a Mac receiver. The switch has two
outputs, the A-output having priority. If the receiver connected to the output having
priority is switched off, the other receiver will control the LNBs. Both receivers can use
the same LNB at the same time provided that the channels transmit with the same
polarisation and in the same band. NB! The receiver having priority is in control.
MATRIX switch
The MATRIX switch is working according to the same principle
as a DiSEqC switch. The MATRIX switch has 4 inputs which
makes it possible to control up to 4 universal LNBs via a
single coaxial cable.
