PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE
2.10
Number of redundant telegrams
For most telegram types, PTM 535Z will transmit the telegram more than once (redundant
transmission) in order to increase transmission reliability. The timing of the individual tele-
gram transmissions is random within a 5ms window.
The number of telegram transmissions is limited by the available energy and therefore de-
pendent on the telegram length (number of bytes to be transmitted).
Typically, PTM 535Z will transmit the following number of telegrams in secure mode:
2 secure data telegrams
1 secure commissioning telegram
Standard mode telegrams are shorter because the sequence counter and the security key
(commissioning telegram) / security signature (data telegram) do not need to be transmit-
ted.
Typically, PTM 535Z will transmit the following number of telegrams in standard mode:
3 data telegrams
3 commissioning telegrams
