DiSEqC Generators: Questions & Answers
The information contained herein may be outdated.
Clearing up some misconceptions about DiSEqC generators and their operation.
What do they generate? Although they are called DiSEqC generates, they usually generate Tone Burst signal.
So that ToneBurst is the same as DiSEqC? Tone Burst is also called Mini DiSEqC. It only allows for the choice of completing two options, e.g. one of two inputs of a switch. Therefore it is not the same; DiSEqC 1.0 or higher is a complex set of commands enabling choice among a number of inputs of a switch, control of a positioner etc.
What is the practical difference between DiSEqC 2.0 and DiSEqC 1.0.? Version 2.0 permits 2-way communication, i.e. ensures confirmation of reception of a command. V 1.0 means one-way communication (the commands are not being confirmed).
Is it important that receiving equipment should support 2.0, or the 1.0 is quite sufficient? Nowadays most of switches or multiswitches support DiSEqC 2.0. But the theoretical possibilities of the standard are practically not utilized. Supposing that the receiving equipment will only cooperate with switches or multiswitches, there is no need for it to support DiSEqC 2.0.
Does ToneBurst have to be generated continuously like 22kHz tone, or once for each command, e.g. one impulse for choosing LNB A and next one for LNB B etc.? Tone Burst signal, similarly to DiSEqC, is generated in the form of single impulses, i.e. the controlled device stores the last received command.
