Abstract:
A method for signaling a device from a control mechanism over a bus comprising:providing a control mechanism; pairing a control signal source with said control mechanism; providing at least one peripheral device having a device id corresponding to a predefined number; pairing a tracking circuit to said at least one peripheral device, said tracking circuit responsive to electrical pulses and capable of matching electrical pulses to said predefined number of said at least one peripheral device to which said tracking circuit is paired; connecting said control signal source and said tracking circuit with a bus interface, said control mechanism operable to generate a series of pulse control signals across said bus interface with said control signal source, wherein said series of pulse control signals is a number of electrical pulses corresponding to at least one of said device ids; sending a control signal from said control signal source along said bus interface to said tracking circuit, said control signal being said series of pulse control signals, wherein said control signal is intended to actuate a corresponding device of said at least one peripheral device, wherein said control signal may be fixed or programmable; said tracking circuit determining whether said control signal corresponds to said device id by counting said series of pulses and comparing said predefined number with said counted pulses; and actuating said corresponding device of said at least one peripheral device when said tracking circuit receives said control signal and said control signal corresponds to said device id.
