1.2 protocol. Such terminology has not been authorised by Eutelsat.

In some cases a single coax cable carries (unidirectional) power and bidirectional data/signals, as in
(Digital Satellite Equipment Control), pronounced "Die-Sec", 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.
was developed by European satellite provider Eutelsat, which now acts as the standards agency for the protocol.
At least a Ka band LNB, dish and DVB-S2 receiver will be required to receive Saorsat. Reception of Sky or Freesat from the Astra 2 satellites at 28° East will require a separate feed and a
or Multiswitch with a
compatible receiver. 2rn state that a dish of 1m diameter is required for reception of Saorsat on the island of Ireland.
The Duo LNB is carefully designed with the correct spacing of the feedhorns,
level 1.0 switching between the satellites and a low noise amplifier and conversion system.
Eutelsat apparently developed the system to allow satellite users in Continental Europe to switch between the more popular SES Astra satellites at 19.2° east and Eutelsat's own Hot Bird system at 13° east. As a result, the vast majority of European satellite receivers support
1.0 or higher, with the exception of all set top boxes manufactured under the Sky Digibox name. All supporting receivers have received certification to carry a logo specifying which variation of
Universal Satellites Automatic Location System (USALS), also known (unofficially) as "
1.3", "Go X" or "Go to XX" is a satellite dish motor protocol that automatically creates a list of available satellite positions in a motorised satellite dish setup. It is used in conjunction with the
1.2 protocol. It was developed by STAB, an Italian motor manufacturer, who still make the majority of USALS compatible motors.
1.2, it is not necessary to manually search and store every known satellite position. Pointing to a known satellite position (for example 19.2ºE) is enough; this position will act as the central point, and the USALS system will then calculate visible satellites position within the offset.
The Freetime spec also includes features such as:
To receive Freesat/Sky or other services alongside Saorsat, a dual- or multi-feed type dish or two dishes are needed with either one or more
switches or a multi-switch. On a multi-switch the Saorsat LNB needs to be connected to vertical 0 kHz port only. The other 3 input ports are left unused.
Monoblock LNBs for 19.2° east and 13° east have been widely available for several years (indeed, the
switching system was originally designed for just this setup). However, these do not function correctly for Astra 23.5°E and Astra19.2°E because these satellites are at a different angular separation.
Vu+, or VuPlus, is made by a Korean multimedia vendor, which is a manufacturer of Linux-based Digital Video Broadcasting (DVB) Satellite (DVB-S), and Terrestrial (DVB-T), digital television receivers (set-top box) with true Digital Satellite Equipment Control (
) support that all currently are MIPS-based and uses Enigma2 toolkit software atop a Linux-based operating system as firmware.
The "Di" (digital) part of the name refers to the digital nature of the signals used by the protocol and does not imply anything about the transmission that the dish is used to receive;
may be used with both digital or analogue satellite systems.
A receiver required to operate in a single cable distribution installation can be essentially conventional. It should be able to tune to the user channel (within the normal IF tuning range) and modulate the LNB power voltage with the 22 kHz signal required for issuing
commands. It will then require only software modification to operate as a single cable distribution receiver.
A dish that is mounted on a pole and driven by a stepper motor or a servo can be controlled and rotated to face any satellite position in the sky. Motor-driven dishes are popular with enthusiasts. There are three competing standards:
, USALS, and 36 V positioners. Many receivers support all of these standards.
Each satellite receiver in the installation has a dedicated user band of a bandwidth approximately the same as a transponder. The receiver requests a particular transponder frequency via a
-compliant command. A mixer in the dish-end equipment (an LNB or distribution unit) converts the received signal to the correct user band IF centre frequency for that receiver.
