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