Abstract

The invention relates to a therapy system and a therapy device having at least one data communication interface which can operate in various data transmission modes and cooperates with a data communication control unit. The data communication interface can change from one data transmission mode to another without interruption of an existing data link. The change is controlled by the data communication control unit as a function of predefined selection criteria.
