A communication interface for a path measuring device is provided. The interface can be coupled between the path measuring device and a control device. A path determination can be carried out by the path measuring device by way of a measurement of the propagation time of measurement signals. A measurement of the propagation time can be triggered by way of control signals on a control signal communication channel. A propagation-time signal communication channel is provided for propagation-time signals. The present invention enables a path measuring device to be used universally and in a simple manner, as the communication interface may be coupled to the control signal communication channel and/or to the propagation-time signal communication channel and digital data may be transmittable between the control device and the path measuring device in addition to control signals for the measurement of the propagation time and propagation-time signals.
