DiSEqC:
is a special communication protocol for use between a satellite receiver and a device such
as a multi-dish switch or a small dish antenna rotor. DiSEqC was developed by European
satellite provider Eutelsat, which now acts as the standards agency for the protocol.
DiSEqC is available in serveral versions:
DiSEqC 1.0, which allows switching between up to 4 satellite sources
DiSEqC 1.1, which allows switching between up to 16 sources
DiSEqC 1.2, which allows switching between up to 16 sources, and control of a simple
horizontal-panning satellite motor
DiSEqC 2.0, which adds bi-directional communications to DiSEqC 1.0
DiSEqC 2.1, which adds bi-directional communications to DiSEqC 1.1
DiSEqC 2.2, which adds bi-directional communications to DiSEqC 1.2
Symbolrate:
This value indicates the data transfer speed. If you need this information to setup your
receiver ( satellitescan) you will nd it for instance under: www.lyngsat.com.
Polarization:
Satellite reception works with two polarizations. That is because the bandwith capacity can
be used more efcient.
In the european area the polarisatzions usually are devided in vertcal and horizontal layers.
Receiver access those layers by using different power thru ZF. 14 V for vertical and 18V for
horizontal.
22KHz:
Das 22 KHz Signal wird benutzt um im LNB zwischen den zwei vorhandenen Frequenz-
bereichen umzuschalten.
lower frequency range:
The lower frequency range is 10.70 - 11.70 GHz ( input frequency)
upper frequency range:
The upper frequency range is 10.70 - 11.70 GHz ( input frequency)
SPDIF
S/PDIF species a Data Link Layer protocol and choice of Physical Layer specications for
carrying digital audio signals between devices and stereo components. The name stands
for Sony/Philips Digital Interconnect Format (more commonly known as Sony Philips Digital
InterFace), the two companies being the primary designers of the S/PDIF format
