Data conversion unit 110 converts the format of the received physiological parameter data. Switch 113 can control and/or direct data between the data conversion unit 110, the medical-analysis station connector 115 and the data-network connector 120. Medical-analysis station connector 115 can transmit the received and converted physiological parameter data to a medical-analysis station 135 for processing. The medical analysis-station 135 can process the physiological parameter data to create processed physiological parameter data. The medical-analysis station connector 115 can also receive processed physiological parameter data from the medical-analysis station 135. The data-network connector 120 can transmit and receive data, such as the processed physiological parameter data, over data network 125 to one or more destinations, such as a central viewing and monitoring station, a network database, and/or a remote processing device.
The patient-parameter-connectors 105 receive patient physiological data in a first format from physiological parameter data generators 130 via cables 117. Patient-parameter-connectors 105 can receive data, such as patient physiological data, from the physiological parameter data generators 130 and can transmit data, such as control data, to the physiological parameter data generators 130. In some implementations, the first format is a serial format and the patient-parameter-connectors 105 are serial ports while the cables 117 are serial cables, although other formats are possible.
The data conversion unit 110 can include a microprocessor or other data processor and can convert data between formats. For example, the data conversion unit 110 can convert data received in a first format on the patient-parameter-connectors 105 to a second format and pass the converted data, via switch 113, to the medical-analysis station connector 115 for transmission in the second format.

Control data can include configuration parameters for the physiological parameter data generators 130, for example, information relating to a patient's age, gender, and device operating settings. The medical-analysis station connector 115 receives control data in the second format, which is passed and/or directed through switch 113 to data conversion unit 110, which converts the control data in the second format to the first format. Patient-parameter-connectors 105 transmit the control data in the first format to one or more of the physiological parameter data generators 130.
Data can be transmitted between the medical-analysis station 135 and the data network 125 via PPC hub 100.

Medical-analysis station connector 115 receives processed parameter data in the second format, which is passed and/or directed through switch 113 to data-network connector 120, which transmits the unmodified processed parameter data in the second format to the data network 125. Data flow line 220 illustrates the reverse data flow, in which data, such as additionally processed physiological parameter data, is sent from the data network 125 to the medical-analysis station 135. Data-network connector 120 receives further processed parameter data in the second format, which is passed and/or directed through switch 113 to medical-analysis station connector 115, which transmits the unmodified further processed parameter data in the second format to the medical-analysis station 135.
