1. A system for monitoring a physiological parameter of a patient, the system comprising:
- a physiological sensor operable to detect a physiological parameter, the physiological sensor comprising a first LED and an information element electrically connected to a common signal line, wherein the first LED operates in response to a drive signal on the common signal line, and the information element provides information data on the common signal line;
a physiological monitor, which provides the drive signal to the first LED and receives the information data from the information element; and
a connector, operable to provide communication between the physiological monitor and the common signal line of the physiological sensor.
