Abstract
A method in a transducer assembly having an external-device interface coupled to a communication protocol interface of the transducer assembly. The transducer assembly is configured to convert an input signal having one physical form to an output signal having a different physical form. At least two electrical signals are received on corresponding contacts of the external-device interface of the transducer assembly. A characteristic of at least one of the electrical signals is determined by evaluating a logic transition of the signal. A unique identity assigned to the transducer assembly is determined based on the characteristic.
