ABSTRACT:
Synchronized communication is provided between a first station and a second station. The first station sets a frame counter to a stored initial value, receives a frame including an identifier uniquely identifying a communication channel designated for communication between the first station and the second station, and increments the frame counter. The frame counter is aperiodically reset to a new initial value, the new initial value being a substantially random number with respect to a previous initial value. When wireless communication is employed, the identifier may be a color code. If the value of the identifier is an expected value, the first station transmits to the second station a return frame including an expected value as a return frame identifier. If the value of the identifier is other than the expected value, the first station resets the frame counter and transmits to the second station a return frame including a selected value other than an expected value as a return frame identifier. A reset counter is incremented after the frame counter is reset. After a predetermined error interval has elapsed since the first occurrence of the step of incrementing the reset counter, and the reset counter has not reached a predetermined value, the reset counter is reset.
