Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung anhand eines stark vereinfachten Blockschaltbildes eines elektrischen Gerätes darge­ stellt.An embodiment of the invention is in the drawing using a greatly simplified block diagram of an electrical device Darge poses.

Beschreibung der ErfindungDescription of the invention

In der einzigen Figur ist ein elektrisches Gerät, das ist zum Beispiel ein Gebührenzähler, mit 10 bezeichnet. Das Gerät weist an seiner Front­ seite 11 eine Einführöffnung 12 auf, in die eine Kodierkarte 13 ein­ steckbar und aus der die Kodierkarte anschließend herausziehbar ist; vgl. Pfeilrichtungen A.In the single figure, an electrical device, for example a charge meter, is designated by 10 . The device has on its front side 11 an insertion opening 12 into which a coding card 13 can be inserted and from which the coding card can then be pulled out; see. Direction of arrows A.

Die Kodierkarte 13 enthält einen elektronischen Kodierspeicher 14, der vorzugsweise als Speicherbaustein vom EEPROM (electrical erasible programmable read only memory)-Typ ausgebildet ist. Anschlüsse 15 des Kodierspeichers enden an Kontaktelementen 16 an der Oberseite der Kodierkarte. Innerhalb des elektrischen Gerätes 10 befindet sich eine der Einführöffnung 12 zugeordnete Abtastvorrichtung 17 mit den Kontakt­ elementen 16 der Kodierkarte 13 entsprechenden Gegehkontakten 18. An die Abtastvorrichtung 17 schließt sich eine elektronische Steuerungsvorrich­ tung 19 an, die mit einem elektronischen Funktionsspeicher 20 verbunden ist. Der Funktionsspeicher 20 ist vorzugsweise ebenfalls ein EEPROM- Speicherbaustein, der mit der elektrischen Schaltung 21 des Gerätes verbunden ist. The coding card 13 contains an electronic coding memory 14 , which is preferably designed as a memory module of the EEPROM (electrical erasible programmable read only memory) type. Connections 15 of the coding memory end at contact elements 16 on the top of the coding card. Inside the electrical device 10 there is a scanning device 17 assigned to the insertion opening 12 with the contact elements 16 of the coding card 13 corresponding counter contacts 18 . The scanning device 17 is followed by an electronic control device 19 which is connected to an electronic functional memory 20 . The functional memory 20 is preferably also an EEPROM memory module which is connected to the electrical circuit 21 of the device.

Die Wirkungsweise des vorstehend beschriebenen Gerätes ist folgende.The operation of the device described above is as follows.

Mit dem Funktionsspeicher 20 ist das elektrische Gerät durch den Her­ steller bzw. Lieferanten auf eine bestimmte Kombination von Funktions­ merkmalen programmiert. Befindet sich das Gerät bei einem Benutzer, der sporadisch eine andere Kombination von Funktionsmerkmalen wünscht, so steckt er eine bestimmte Kodierkarte 13, deren Kodierspeicher 14 eine der gewünschten Kombination entsprechende Kodierung bzw. Program­ mierung enthält, in die Einführöffnung 12 des elektrischen Gerätes. Die Abtastvorrichtung 17 kommt dabei mit ihren Gegenkontakten 18 in Eingriff mit den Kontaktelementen 16 der Kodierkarte 13. Mit der Abtastvorrichtung 17 und der Steuerungsvorrichtung 19 wird die in dem Kodierspeicher 14 gespeicherte Kodierung ausgelesen und auf den Funk­ tionsspeicher 20 übertragen. Durch teilweises oder vollständiges Über­ schreiben des vorher in dem Funktionsspeicher gespeicherten Programms wird die neue Kombination von Funktionsmerkmalen gespeichert.With the functional memory 20 , the electrical device is programmed by the manufacturer or supplier to a specific combination of functional features. If the device is with a user who sporadically wishes a different combination of functional features, he inserts a specific coding card 13 , the coding memory 14 of which contains a coding or program corresponding to the desired combination, into the insertion opening 12 of the electrical device. The scanning device 17 comes with its mating contacts 18 into engagement with the contact elements 16 of the coding card 13 . With the scanning device 17 and the control device 19 , the coding stored in the coding memory 14 is read out and transferred to the radio function memory 20 . The new combination of functional features is saved by partially or completely overwriting the program previously stored in the functional memory.

Mittels einer weiteren Kodierkarte, deren Kodierspeicher eine andere Kodierung enthält, kann der Funktionsspeicher 20 später wieder auf eine neue Kombination von Funktionsmerkmalen umprogrammiert werden.By means of a further coding card, the coding memory of which contains a different coding, the function memory 20 can later be reprogrammed to a new combination of function features.

Ist das elektrische Gerät ein Gerät, das ohnehin durch Chipkarten oder dergleichen gesteuert wird, dann sind für die Anwendung von Kodierkar­ ten 13 nur geringfügige schaltungstechnische Änderungen und Ergänzungen erforderlich. Damit die normalen Chipkarten und die Kodierkarten ausein­ andergehalten werden können, weisen die Kodierkarten ein besonderes Kenn­ zeichen auf, das das elektrische Gerät bzw. die Abtastvorrichtung 17 auswertet. Nur beim Erkennen dieses besonderen Kennzeichens findet die Umkodierung des Funktionsspeichers 20 statt. Das besondere Kennzeichen besteht vorzugsweise in einer speziellen Kodierung des Kodierspeichers 14.If the electrical device is a device that is controlled anyway by chip cards or the like, then only minor circuit changes and additions are required for the application of coding cards 13 . So that the normal chip cards and the encoding cards can be kept apart, the encoding cards have a special identifier that evaluates the electrical device or the scanning device 17 . The recoding of the functional memory 20 takes place only when this special identifier is recognized. The special characteristic preferably consists of a special coding of the coding memory 14 .
