Diseqc Protocol4/9/2021
For a better experience, please enable JavaScript in your browser before proceeding.DiSEqC was developed by European satellite provider Eutelsat, which now acts as the standards agency for the protocol.
DiSEqC is commonly used to control switches and motors, and is more flexible than 1318 volt and 22 kHz tone or ToneBurstMiniDiSEqC techniques. DiSEqC is also compatible with the actuators used to rotate large C band dishes if used with a DiSEqC positioner. The later versions are backwards compatible with the lower revisions, but the lower revisions are, as might be expected, not forwards compatible with the higher revision numbers. Usually this is not important, as the switch or motor can be controlled by the receiver without problems. 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 Eutelsats own Hot Bird system at 13 east. As a result, the vast majority of European satellite receivers support DiSEqC 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 DiSEqC they support. For example, 1.3 usually refers to a receiver which uses USALS in conjunction with the DiSEqC 1.2 protocol. Such terminology has not been authorised by Eutelsat. DiSEqC uses a pulsed (tone-burst) 22 kHz sine-wave at 0.5v peak to peak. Source: Wikipedia. A reciver should be capable of sending diseqc 1.1 protocal cammands.
