Transportable, Configurable Data Carrier For Exchanging Data Between Electrical Devices, and Method Therefor
First Claim
1. Portable data carrier (IT) for data exchange between electrical devices with a control unit and a memory, comprising:
- a single interface circuit (I) to be connected to the respective device;
a data memory (SP) for temporarily storing the data fed by the respective device;
input and display (T, A) for user-controlled operation and user guidance;
and a control unit (ST) that is connected to the same and is provided with a program memory (PS) for executing application programs and communication functions,such that an authentication process is carried out, the transfer mode (master/slave) and the direction of the data transfer are automatically detected, and the adequate transmission type/speed/protocol for downloading the data are selected according to said authentication and identification processes with the aid of said control units (ST) for configuration purposes when said data carrier (IT) is connected to the respective device, and memory areas of said data memory (SP) can be read in and out and deleted only once the authentication process has been successful.

Abstract
Adequately designed transportable data carriers are used for different applications. In order to allow for individual, particularly automatically adjustable, interactive configuration and allow also inexperienced users to rapidly transfer data, the invention relates to a data carrier comprising a single interface circuit to be connected to the respective device, a data memory for temporarily storing the data fed by the respective device, input and display means for user-controlled operation and user guidance, and a control unit that is connected to the same and is provided with a program memory for executing application programs and communication functions such that an authentication process is carried out, the transfer mode (master/slave) and the direction of the data transfer are automatically detected, and the adequate transmission type/speed/protocol for downloading the data are selected according to said authentication and identification processes with the aid of the control units for configuration purposes when the data carrier is connected to the respective device, and memory areas of the data memory can be read in and out and deleted only once the authentication process has been successful.

5. Method for data exchange between electrical devices with a control unit and a memory carried out by a portable data carrier (IT), comprising a single interface circuit (I), a data memory (SP) for temporarily storing the data fed by the respective device, input and display (T, A), and a control device (ST) provided with a program memory (PS) for executing application programs and communication functions, whereas for configuration purposes the control units (ST):
-
an authentication process shall be carried out upon connection of said data carrier (IT) to the respective device; an automatic detection of a transfer mode (Master/Slave) and of the direction of the data transfer shall be carried out; a selection of the adequate transmission type/speed/protocol for downloading the data shall be carried out; and only once the authentication process has been successful memory areas of said data memory (SP) can be read in and out and deleted. - View Dependent Claims (6, 7, 8, 9, 10, 11)
