Multipurpose Sensor Port
First Claim
1. A device configured to allow digital communication between a sensor port of a patient monitor and a digital data source external to the patient monitor, the device communicating over conductors at times tasked with communicating analog drive signals to a sensor and conductors at times tasked with communicating analog signals to the patient monitor indicative of light detected by said sensor that has been attenuated by body tissue, said device comprising a sensor port interface configured to provide mechanical and signal level compliance between said sensor port and said digital data source, said sensor port digitally communicating through said sensor port interface with said digital data source, said sensor port communicating said analog signals with said sensor and wherein only one of said sensor or said sensor port interface can be connected with said sensor port at a time.

Abstract
A sensor port is adapted to connect to either a sensor or a data source. A reader is configured to identify which of the sensor and the data source is connected to the sensor port. A data path is configured to communicate an analog signal associated with the sensor and digital data associated with the data source to a signal processor according to the identification made by the reader.
