System comprising a master unit and a plurality of slave units for operating a plurality of devices

摘要

System comprising at least one master unit and a plurality of slave units, wherein said master unit and said slave units comprise means for performing communication via radio frequency channels. The at least one master unit comprises means for transmitting control signals to said slave units, and the slave units are each provided with a unique address and are each associated with a controllable device. The at least one master unit comprises means for executing a sequential transmission of control signals to at least one of said slave units upon activation of a function control key. The master unit is configured for transmitting a status request signal to a slave unit that has received a control signal, which status request signal is transmitted after a time delay corresponding to the time taken by the slave unit to perform an operation in response to the received control signal.
