The simplest way to connect several components to the receiver is to cascade with loopthrough components. By doing so, the signal path from the receiver is distributed in each component. Since the components mostly differ in the switching criterion, a general family address is often possible. But it must be noted at this point that the slaves located behind the first changeover switch "do not respond" to the first DiSEqC command. It is therefore necessary that the satellite receiver either puts out the various DiSEqC commands in the right order or repeats the complete path description (command 38) often enough. Up to three cascaded components are supported in DiSEqC systems.
