  • Page 35: Appendix

    The ETS requires the user to press the programming button if no direct access to the devices is possible due to an active energy-saving mode. Jung KNX RF devices correspond to the KNX standard "KNX RF1.R S-Mode". Devices of other manufacturers, which meet the same standard, are intercompatible. Frequently, for marketing reasons, different names or product designations are used for the same KNX RF system.
  • Page 36 0.5...25 mW is possible. The system makes a communication channel available for all devices. The transmission time of each device (Duty-Cycle) is 1 % (maximum transmission time 0.6 seconds in one minute). This avoids continuous transmissions, meaning that the transmission channel is not permanently blocked. Art. No. MK100RF Page 36 of 57...
  • Page 37 If complete separation of RF domains or the integration of media couplers into their radio ranges cannot be guaranteed structurally, then it may be better to create only one radio domain instead of multiple media couplers and to work with repeaters. Art. No. MK100RF Page 37 of 57...

    For KNX RF, the data rate is 16.384 kBit/s. Manchester encoding is used to apply the "0" and "1" information to the radio signal. This allows very easy synchronisation of the transmitter and receiver. Art. No. MK100RF Page 39 of 57...

    An absolutely simultaneous reaction to system telegrams (broadcast) or group read telegrams (Read flag set on more than just one subscriber) is not possible on Jung KNX RF devices. With more than two RF lines in a KNX installation, communication problems can become so great that secure data transmission, and thus a fault-free function of the KNX system, is not possible, either temporarily or continually.
