    List of Variables

    When Cardiocap is connected together with Capnomac Ultima, variables of both monitors are received together.
    Units of variables are given at runtime by a call to the Input() property of the Datacaptor Control.

    See the Unit Codes for this DDI.

    A unit code is returned with each variable after a call to "Input" or "DriverOutput" Control properties.

    If the variables always have the same unit code, each variable unit code is given by the ‘DriverOutput’ property; the "Input" property does not return any unit code value (all unit codes fields are 0).

    If the variables don't always have the same unit code (a unit may dynamically change), each variable unit code is given by the "Input" property; the ‘DriverOutput’ property does not return any unit code value (all unit code fields are 0).
