In development, compromising emissions may be radiated from the I/O panel of an electrical device, such as a personal computer. Normally, to prevent these emissions, filters are generally used within the device on the inside of the I/O panel such that no compromising emanations can escape through the connector when the external cable is not connected. In some cases, it is not possible to filter signals without affecting signal quality and subsequent performance of the attached device. In these cases, it becomes necessary to provide external protection at the I/O panel connector to prevent these emissions when the external cable is not connected to the I/O connector. To prevent these emissions, a special connector cover has been designed which contacts the I/O panel gasket all around the connector periphery.
