When using parallel operation, all of the components are always connected to the bus; therefore special administration is necessary. Since it may occur that several identical components (with the same address and function) are connected simultaneously to the bus, collision recognition is implemented in the system. Additional address space is available to readdress the components. To control all this the DiSEqC master (satellite receiver) must have a very complex software code. Also, the distribution of the high frequency has its problems.
