1. GENERAL DESCRIPTION
The radio transmitter device PTM 200C from EnOcean enables the implementation of
wireless remote controls without batteries. Power is provided by a built-in electro-
dynamic power generator.
The PTM 200C device serves the 315 MHz air interface protocol of EnOcean. Together with the
receiver device RCM 130C, 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 by an appropriate push button 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” push button 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 blinds control including slat action are simple to implement.
In addition, the PTM telegram transmits the operating status of the contact nipples (2) when
pressing the bow. This enables the identification of up to 2 appropriate switch rockers or up to
4 pushbuttons.
