Abstract:
1. An electronic system comprising: a) at least one electrical output, and b) at least one physical switch, the system configured to receive a series of discrete, packetized, radio frequency transmissions, the transmissions containing at least a first field encoding a signal state where the encoding is a representation of a state to which the system sets a first of the at least one electrical outputs while the system is receiving valid transmissions; further, the system comprising logic to force the first electrical output to a fail-safe state upon interruption of valid reception and where the fail-safe state is configured by setting at least one physical switch to one of a plurality of distinct, independent and user settable switch settings; a first distinct switch setting signifying a first predetermined fail-safe state and a second distinct switch setting signifying a distinct second predetermined fail-safe state and a third distinct switch setting signifying that the state that was encoded in the first field of the last valid packet received is to be the fail-safe state.
