    The unique Key ID number for the relevant transponder key is downloaded to the higher- level process controller using a defined protocol, depending on the coded communication mode. The communication mode is coded on the Key ID interface of the PIT m4SEU (jump- ers available/not available).

  • Page 34: Advanced Communication Mode

    Coding: IN n. c. In handshake-controlled communication mode, the PIT m4SEU can be operated in a func- tional variant. In this case the Key ID number of the transponder key is not downloaded to the controller. The controller is only used to evaluate IDsync on the Key ID interface. In this case IDsync is used as a signal output, enabling the controller to recognise whether the transponder key is valid/invalid.

  • Page 35: Evaluation By A Controller

    No transponder key is inserted or the transponder key that is inserted is invalid. "1" signal A valid transponder key is inserted. The PIT m4SEU signals to the controller when the download starts. The signal is present for 100 ms.
  • Page 36 Receive Bit 13 … Bit 00 Download procedure The PIT m4SEU sets the signal at IDsync (control line) to "1" for 100 ms, thereby signalling to the controller that download has started. A rising edge at IDclock (test pulse line) indicates that the data at data lines IDout0 and IDout1 is present and valid and can be read by the controller.

    End of Key ID Number Transfer (200 ms) IDend After the last falling edge at IDrequest, the PIT m4SEU still has a "1" signal at output IDresponse for 200 ms. In this way, the end of the Key ID number and therefore the end of the download (End of Key ID Number Transfer) is displayed.
