What is DiSEqC?
DiSEqC is a technological solution, developed and copyrighted by Eutelsat, to enable a single receiver to operate two LNBs simultaneously. This is used, for example, if you have two LNBs (pointing two different satellites) and the signal is convoyed to a single satellite receiver. If you use reception on 7 degrees only for PC services you do not need DiSEqC.
A. DiSEqC (“Digital Satellite Equipment Control”) Standard system used to control digital-enabled satellite installations. For instance, DiSEqC can effect switching between several satellite dishes, or can control more complex Multifeed installations (e.g. ASTRA and EUTELSAT), the positioning of a motorised dish, control of a multi-party installation (Multiswitch), etc. Several levels or versions of DiSEqC are available, offering a varying range of functions.
A. DiSEqC (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. DiSEqC relies only upon a coaxial cable to transmit both bidirectional data/signals and power. DiSEqC is commonly used to control switches and motors, and is claimed to be more flexible than 13/18 volt and 22 kHz tone or ToneBurst/MiniDiSEqC techniques. DiSEqC is also compatible with the actuators used to rotate large C band dishes if used with a DiSEqC positioner. Despite its name, it has been used on fully analogue or only partially digital-capable (Astra Digital Radio) satellite receivers. A number of variations of DiSEqC exist: 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 mot
