1. A resistance emulator comprising:

  • a first plug configured to couple with a medical monitor configured to receive a calibration resistance value from a coded resistor of a medical sensor, wherein the first plug comprises a first plurality of pins in a pin configuration;

    a second plug configured to couple with a medical sensor configured without the coded resistor, wherein the second plug comprises a second plurality of pins in the pin configuration; and

    emulation circuitry configured to receive calibration data from a memory of the medical sensor through a first pin and a second pin of the first plurality of pins and to provide a signal correlative to the calibration resistance value to the medical monitor through a third pin of the second plurality of pins, wherein the first, second, and third pins each comprise a different pin position in the pin configuration.
