Systems, methods, and devices for intercommunication between a medical sensor and an electronic patient monitor are provided. For example, one embodiment of a system for communicably coupling a medical sensor to an electronic patient monitor may include a sensor-side communication connector and a monitor-side communication connector. The sensor-side communication connector may be capable of receiving a raw physiological measurement signal from the medical sensor, and the monitor-side communication connector may be capable of providing a digital physiological measurement signal based at least in part on the raw physiological measurement signal to the electronic patient monitor via a data link.
