User defined operation
Via the configuration interface it is possible to define different content of DATA_BYTE3 and
define if a N-message or U-message shall be sent. This allows for example to transmit
other ORG=5 telegrams, e.g. “Mechanical handle”, as described in the EnOcean Equipment
Profiles defined by EnOcean Alliance.
2.8
Transmit timing
The setup of the transmission timing allows avoiding possible collisions with data packages
of other EnOcean transmitters as well as disturbances from the environment. With each
transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmis-
sion of a subtelegram lasts approximately 0.7 ms. The delay between the three transmis-
sion bursts is affected at random.
