Field devices for measuring a pressure or a fill level are connected, by way of a cable connection or a radio connection, to stationary evaluation- and display devices. According to an exemplary embodiment of the present invention, a parameterisation- and data recording system for a field device is stated, which system makes it possible to maintain fast and flexible communication between field devices and a mobile control device. For this purpose the system comprises a connection box and an interface adapter, which converts a HART signal or an I.sup.2C signal to a USB signal.
