ABSTRACT:
A system is disclosed. The system has a first receiver, a second receiver, and an input device configured to transmit a command signal in response to user input. The system also has an input waveguide having a first end in communication with the input device and terminating at the first receiver, and a second end in communication with the second receiver. The input waveguide is arranged to receive and route the command signal to the second receiver. The system also has an output waveguide having a first end in communication with the first receiver, and a second end in communication with the second receive. The second receiver is configured to determine whether the command signal is directed to the first receiver and/or the second receiver based a code contained in the command signal. The second receiver is further configured to execute the command signal when it is determined that the command signal is directed to the second receiver, and relay the command signal through the output waveguide to the first receiver for execution when it is determined that the command signal is directed to the first receiver.
