Abstract

A device for protecting sensitive electronic equipment from low level signal lines short circuited to high voltage power sources includes a switch that open the circuit between the data lines and the sensitive computing equipment if a high voltage condition is detected on the data lines. Otherwise, the switch remains closed and data can be transmitted to the computing equipment.
