2.3.1
Transmission timing
The transmission timing of the radio module PTM 240C has been developed to avoid possi-
ble collisions with data packages of other EnOcean transmitters as well as disturbances
from the environment.
With each transmission cycle, up to 3 identical subtelegrams are transmitted. The transmis-
sion of a subtelegram lasts approximately 1.2 ms. To optimize data security, each telegram
is repeated several times within about 40 ms, whereas the delay between the second and
the third transmission burst is effected at random.
2.3.2
Telegram Data
The PTM 240C transmits an EnOcean radio telegram according to profile 0b000111 – Occu-
pancy Sensor - type 0b0000001 as defined in “Standardization EnOcean Communication
Profiles V1.03”.
For detailed information on the serial protocol please refer to the user manual of TCM2xyC
and the above standardization document.
A teach-in telegram is transmitted, if SW2 is connected to SW_HIGH. This telegram con-
tains the above mentioned profile an type information as well as a manufacturer ID which is
0b11111111111 (multiuser ID) in this case.
In case SW2 is left open the module transmits a data telegram with the information about
the status of the PIR sensor which has to be coded using SW1.
The information transmitted is:
