He first checks, for example, whether the presence duration corresponds to a time period which is assigned to the teaching mode, step 48. For example, the teaching mode can be assigned a presence duration of the actuating element from zero to 30 seconds. If applicable, he executes the learners mode of operation explained later, step 80. If the main actuating element 20H is present longer than the presence duration assigned to the teach-in mode, the microprocessor 13 subsequently checks whether the presence duration corresponds to a time period which is assigned to the usage conditions mode, for example a presence duration of 30 to 120 seconds can be provided for this.

If the check in step 50 shows that the main operating element has not been removed from the range of the base station 10 even in the time period assigned to the operating conditions operating mode, the microprocessor 13 checks whether the Presence of the actuator tion element corresponds to a time period which is assigned to the auxiliary key assignment operating mode, for example by checking whether the main operating element 20H is present for up to 240 seconds. If applicable, he continues with the execution of the auxiliary key assignment operating mode, step 66. A check for the delete operating mode is then carried out analogously, step 54.

  • the basis for the determination can be, for example, a predetermined ranking of the actuating elements 20, in which, for example, initially the actuator 20 with the lowest group number is selected.
  • the microprocessor 13 informs the selected actuating element by sending its group number. All other actuating elements with other group numbers that may be present no longer participate in the subsequent communication. For this purpose, it can be provided that the microprocessor 13 issues a command to the actuating elements 20 which are not involved, as a result of which they are brought into a sleep mode.
  • the base station 10 then subjects the selected actuating element 20 to an assignment correctness check, step 60. In the example, this is done using the known challenge response method.
  • the base station 10 emits a challenge signal via its transceiver 11, which is only intended for the selected actuating element 20 and is only carried out by the latter. At the same time, the base station-side microprocessor 13 determines a target response signal.
  • the calculation is carried out from the challenge signal according to a predetermined algorithm using the cryptographic key stored in the memory 31 and the manufacturer code 17 in the memory 15 of the actuating element 20 to be assigned 20 received, decoded in the decoder 22 and fed to the microprocessor 24.

  • Further follow-up measures can also be provided, for example a repetition of the assignment procedure. If the test reveals that the control element 20 returned by the actuating element sponse signal with the previously determined target response signal, there is a confirmation that the assignment is correct. It expediently takes place in a form that is perceptible to the user optically or acoustically and leads, for example, to the release of the base station 10.
  • the microprocessor 13 first subjects the main actuating element 2OH to an assignment correctness check, analogously to the assignment correctness check when assigning an actuating element 20 in accordance with step 75. If a correct assignment of the main actuating element 20H and base station 10 is found, the microprocessor 13 checks on the basis of the directory 18, whether there are still free group numbers that have not yet been assigned to an actuating element, and an assignment of further actuating elements 20 to the base station 10 is possible at all, step 81. In the event of a negative determination, the teaching operation is terminated, step 70 If the determination is positive, a check follows as to whether actuation elements 20 which have not yet been trained are located in the range of the base station.
  • the microprocessor 13 initiates the transmission of a zero search signal, step 83, which, for example, sees the shape of a special serial number for the brand-new actuating elements 20 and has a serial number that can be executed directly for this. It is expediently present as an unchangeable reference signal 34 in the memory 25 of each actuating element.
  • a zero search signal When a zero search signal is received, their respective microprocessors 24 each cause the output of a contact signal which is initially randomly controlled.
  • the base station 10 checks its input, step 84. Then, if at least one contact signal has been received from a brand-new actuator 20, it carries out a routine to ensure that the subsequent communication is only ever with an actuator 20 to be re-learned. Step 85 follows. Such a separation routine is described in the aforementioned German application, file number 196 45 769.6, to which reference is made. If no contact signal is received, teaching is aborted, step 70.
  • the microprocessor 13 After a single active actuating element 20 to be learned has been separated in the range of action of the radio link 30, the microprocessor 13 initiates the transmission of the serial number 16, the cryptographic code key 31, as well as one of the characteristic group number 26 assigned to the actuating element 20 in the future.
  • the transmitted code information 16 , 26, 31 takes over the actuating element 20 in the spaces provided for it in the memory 25, which have been available until then.
  • the actuating element 20 sends an acknowledgment signal to the base station 10, step 87. This is expediently the manufacturer code 27, which the base station-side microprocessor 13 stores in the memory 15 in the case of the previously assigned group number.
  • the microprocessor 13 then issues a lock command to the newly assigned actuating element 20, step 88, which has the effect that the serial number 16 previously written into the memory 25 and the cryptographic code information stored in the memory 31 are protected against writing and reading.
  • the actuating element 20 is then assigned to the base station 10.
  • the teaching in of a new actuating element 20 also registers the main actuating element 20H, for example on the basis of the lock command previously issued by the microprocessor, and requests the base station 10 to transmit the manufacturer code 17 of the new actuating element 20.
  • the main actuating element 20H determines with the aid of the in its Memory 25 existing information 33 on the number of actuators 20 and assigned to base station 10 whose manufacturer codes represent the total number of assigned actuating elements 20 after the new actuating element has been taught and transmits the number of bass station 10, step 90.
  • the microprocessor 13 checks whether it matches the number of actuating elements 20 registered in the directory 18, step 92 If so, it confirms the new total number to the main operating element 20H, expediently by returning the registered number.
  • the main operating element 20H then takes over the manufacturer code 27 of the newly added operating element 20 and the new total number in its memory 25. If the number determined by the main operating element 20H and the number determined by the microprocessor 13 do not match, no registration takes place.
  • the base station 10 issues a wake-up command, by means of which the possibly existing further actuating elements 20, which are in the sleep state, are activated again.
  • the teaching of further actuation elements 20 to be reassigned can then be continued by repeating steps 83.
  • actuation elements that have already been taught in can also be taught in, ie a serial and a group number are already present in their memory 25.

  • the base station 10 In the operating mode of operation, the base station 10, after selecting an actuating element 20, first carries out an assignment correctness check for the main actuating element 2OH, step 60, then an assignment correctness check for the selected actuating element 20.
