A signal encoding and decoding protocol to transmit both clock information and a data payload in a single line is disclosed. Data may be encoded in a unipolar non-return-to-zero line in which an initial pulse width determines a clock frequency, followed by a series of pulses indicating the data payload. Each clock transition following an initial synchronization pulse indicates a data bit in which the value of the bit is determined in relation to the previous bit. Edge information may indicate a change in bit value from the previous bit. If the transmission signal remains at the same level for a subsequent clock period, the bit value remains the same.

A method and a device perform data communication between a superordinate computer system of an ultrasonic measurement system and an associated ultrasonic sensor via a modified UART data interface. The method and device exit the UART protocol and use a special signaling protocol and a modification of the UART data interface for the duration of an ultrasonic measurement phase to transmit the arrival of echoes at the ultrasonic sensor promptly to the superordinate computer system and return to the UART protocol for the data transmission from the ultrasonic sensor to the superordinate computer system after the end of the ultrasonic measurement phase.
