Abstract
This invention is a signal coupler that works with, but is not restricted to multi-satellite, multi-receiver systems using one cable with a multi-slot transponder selector. The invention solves the difficulty of connecting a multi-output signal coupler to multiple receivers, where each receiver exhibits the characteristics of a master as specified by the DiSEqC protocol. By using a microcontroller with store and forward characteristics, it solves the issues of receiver command collisions, and is able to direct return commands (in DiSEqC 2.x systems) to only the receiver that initiated the communication.
