Abstract:
A system for establishing communication between a system controller and a system component via a communication link, the communication link being configured to carry a control signal and data communication signals in at least one channel of a plurality of channels, the system comprising:a first controller in the system controller for selectively assigning the control signal to a particular channel of the plurality of channels; a transmitter in the system controller for periodically transmitting, through the communication link and in said particular channel, the control signal to the system component; and a second controller in the system component for scanning the plurality of channels for a predetermined first time period to identify said particular channel, and operable for: (i) receiving the control signal from the identified particular channel and establishing communication with the system controller via the communication link in accordance with the control signal when said particular channel is identified during said predetermined first time period, and (ii) determining whether a reset condition is met when said particular channel is not identified during said predetermined first time period, and: (A) when said reset condition is determined to be met, resetting the system component, restarting said predetermined first time period, and resuming said scan of the plurality of channels, and (B) when said reset condition is determined to be not met, restarting said predetermined first time period, and resuming said scan of the plurality of channels to identify said particular channel.
