1. GENERAL DESCRIPTION
The radio transmitter device PTM 200 from EnOcean enables the implementation of
wireless remote controls without batteries. Power is provided by a built-in electro-
dynamic power generator.
The PTM 200 device serves the 868 MHz air interface protocol of EnOcean. Together with the
receiver devices RCM 110 or RCM 120, this device can be easily integrated in operation and
control units for the implementation of different application-specific system solutions.

1.1 Functional Principle
A common electro-dynamic energy transducer is actuated by a bow (1), which can be pushed
from outside the device on the left or right by an appropriate pushbutton or switch rocker.
When the energy bow is pushed down, electrical energy is created and an RF telegram is
transmitted including a 32-bit device ID. Releasing the energy bow generates different
telegram data, so every PTM telegram contains the information that the bow was pressed or
released.
“Long” or “Short” pushbutton operation (the time between pushing and releasing
the pushbutton) can be easily detected by the receiver. By doing that, applications
such as dimming control or jalousie control including slat action are simple to
implement.
In addition, the PTM telegram transmits the operating status of the contact nipples (2) when
activating the bow. This enables the identification of up to 2 appropriate switch rockers or up
to 4 pushbuttons.
