A distance monitor for a loading dock includes a sensor monitoring the distance between itself and a vehicle approaching the sensor to generate an analog distance signal representative of the measured distance. The sensor further includes an analog to digital converter that produces a digital distance signal which is transmitted for further processing. The distance monitor also includes a control logic unit coupled to the sensor. The control logic unit includes an input for receiving the digital distance signal, a logic system for converting the digital distance signal for presentation and a display for viewing the distance information.
