Pulse oximetry systems, subsystems and communication converter for its construction

Pulse oximetry system, communication converter for converting to fit the pulse oximeter to generate a biometric information data, a communication method of the display apparatus communication method received the biometric information data biometric information data from the pulse oximeter When comprised of a communication converter and a display device for receiving biological information data. Further, a plurality of candidate communication method in a storage unit of the communication converter are stored. The user can be set as a communication mode after selecting converts compatible communication scheme and the display device from among the candidate communication method. Therefore, if compatible with the communication method of any display device of the plurality of candidate communication scheme, it is possible to communicate via a communication converter even if the mode of communication with the display device and the pulse oximeter differ .
