GENERAL DESCRIPTION
The radio transmitter module PTM 240C from EnOcean enables
the implementation of batteryless occupancy sensors for
applications in building technology. Power is provided by an
external short energy pulse.
The PTM 240C module serves the 315 MHz air interface protocol
of EnOcean. Together with the transceiver module TCM2xyC,
this module can be easily integrated in operation and control units for the implementation
of different application specific system solutions.
1.1
Functional Principle
When a short energy pulse is supplied to the PTM 240C module an RF telegram is transmit-
ted including a 32-bit module ID. In addition the information of 2 inputs is transmitted.
These inputs shall be used in the application circuitry to connect a learn button and the
evaluation unit of a passive infrared sensor (PIR).
