Abstract
A connector of a sensor probe and its receptacle on a console have security mechanisms that ensure that the connector and the receptacle are properly connected and mated. The connector and receptacle can have physical security features that block insertion of the connector into the receptacle if they are not aligned in a proper orientation. The console can also include a software security feature that allows optical measurements from the sensor probe only if the connector of the sensor probe and receptacle on the console are connected properly. An adapter can also be used to convert a conventional receptacle mounted on a console into a receptacle with security features.
