Patent ID: 7375647

Claim:
A method of transmitting metric data from a medical data collecting device having a unique resistor value via an intermediate device having a fixed resistor value to a server computer, the method comprising: receiving the unique resistor value from the medical data collecting device; determining a cable type of a medical data collecting device by dividing the fixed resistor value by the unique resistor value of the intermediate device, thereby deriving an analog value; transmitting a cable type value corresponding to the cable type to a server computer; receiving device configuration instructions from the server computer, the server computer using the cable type value to identify the medical data collecting device and storing configuration data for a plurality of medical devices; configuring a multiplexer in the intermediate device to an appropriate output level and to an appropriate bit rate to enable communication with the medical data collecting device; and receiving metric data from the medical data collecting device at the intermediate device for transmission to the server computer.
