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.

1.2 Typical Applications
• Building installation
• Industrial automation
• Consumer electronics
Key applications are wall-mounted flat rocker switches with 1 or 2 rockers (with medial
position), as well as handheld remote controls with up to 4 single pushbuttons.
The PTM 200 device is part of a powerful RF system solution from EnOcean for operation and
control applications. Because the RF transmitters are self-powered (no batteries),
maintenance-free RF systems are possible. The RCM devices operate together with the
following additional EnOcean components: RCM (general-purpose radio receivers), STM (solar-
powered wireless sensors), CTM (remote control) and TCM (bi-directional IT interface and
repeater).

2.2 Contact Nipples Designation
With 4 contact nipples, the PTM 200 offers 2 channels with 4 action states each (upper/lower
nipple is pressed/released when activating the energy bow). The nipples’ designation is as
follows:

BA
CHANNEL
STATE
O

CHANNEL
STATE
Figure 10: Contact nipple designation
Radio signals of the PTM 200 device are event-controlled (energy bow is pressed/released)
with contact nipple code (channel/state) and unique device identification (fixed 32-bit ID).
When operating more than one nipple at the same time, note that PTM 200 sends multiple-
button code combinations (switch device of Type 2, unlike PTM 100):
• N-message: One or two contact nipples have been pressed when activating the
energy generator Æ Message with nipple code and pressed/released event status of the
energy bow is sent.
• U-message: No contact nipple was pressed when activating the energy generator,
or 3 or 4 nipples have been pressed Æ Message with pressed/released event status
of the energy bow is sent and the information if either none or more than two nipples
have been pressed. Note that it can’t be differentiated if 3 or if 4 nipples have been
pressed.
Note: Due to the mechanical hysteresis of the energy bow, in most rocker switch
device implementations, pressing the rocker sends an N-message and releasing the
rocker sends a U-message!

2.3 PTM 200 Radio Telegram
For the transmission of the telemetric signals, EnOcean has defined a new dynamic radio data
telegram that is adapted to the individual application. It is optimized to the essential features
of energy autarkic radio sensors:
• Minimal energy demand
• Possibility of operating hundred of senders within the same radio cell
• Maximum transmission reliability
• Wide transmission range
• Easy extensibility
• Suitable for uni- and bi-directional communication
• Flexibility for adaptation of different data structures and data quantities
• Data encryption option
2.3.1 Frequency range
The EnOcean technology operates the 868.3 MHz radio channel (868.0 – 868.6 MHz), which is
exclusively released for short-time data transmission in Europe. Timing conditions can be
found in chapter 3.5 of this paper.
Because of the very low radiated field strength on average, the 868.3 MHz EnOcean radio
technology can be approved in the USA and in Canada. Timing conditions can be found in
chapter 3.6 of this paper.
2.3.2 Modulation process
As modulation process, EnOcean uses incoherent amplitude modulation (ASK). Digital
amplitude modulation enables the implementation of very efficient energy-saving transmitters
because only the “1”-bits are transferred. At the same interference signal level, the
transmission security of the alternative FSK method is identical to that of the ASK method
(Reference: Pehl, Digitale und analoge Nachrichtenübertragung, Hüthig 2001).
2.3.3 Transmission timing
The transmission timing of the radio device PTM 200 has been developed to avoid possible
collisions with data packages of other EnOcean transmitters as well as disturbances from the
environment.
With each transmission cycle, at least three identical subtelegrams are transmitted. The
transmission of a subtelegram lasts approximately 0.7 ms. To optimize data security, each
telegram is repeated twice within about 20 ms, whereas the delay between the second and the
third transmission burst is effected at random. If some residual energy is available after
transmission of three subtelegrams, up to 2 further subtelegrams are sent.

2.3.4 Reliable radio transmission within systems operating many sensors
The very short telegrams of EnOcean transmitters enable the operating of a large number of
senders within the same radio cell; the error rate caused by telegram collisions remains
extremely low. Statistically viewed, the transmission reliability is still greater than 99.99% in
the case of 100 radio sensors that transmit once every minute. This means that even large
office buildings and also huge industrial facilities can be equipped with a large number of
sensors of this kind of radio technology.

2.4 PTM 200 Serial Data Communication via Receiver Device RCM 120
The RCM 120 Receiver Device of EnOcean enables standard asynchronous communication to
a microcontroller or personal computer with a decompressed and simple data structure (9600
bps, 1 start bit, 8-bit data byte with LSB first, 1 stop bit).
When the RCM 120 receiver is set to Mode 0 “Serial Interface”, it transfers out data blocks of
information from all received EnOcean radio telegrams (from PTM-, STM-, TCM- and CTM-radio
devices). For a complete transmitter message, a telegram of 14 data bytes is transferred via
the serial link.
The data block format is explained in detail in the RCM 110/120 User Manual.
Figure 13: Receiver devices RCM 110 and RCM 120
2.5 Basic Switching Features via Receiver Devices RCM 110 and RCM 120
The multifunctional RCM 110 and RCM 120 Radio Receiver Devices are used to receive
and process PTM-telegrams generated and transmitted by EnOcean radio transmitters. Via
functional control outputs (“open collector”), these devices can be easily integrated into
control and switching units for the implementation of different application-specific system
solutions.
RCM 110 output switching functionalities (controlled by PTM radio signals)
• Basic signal output functions “switching” (On/Off): 1, 2 or 4 channels
• Basic signal output function “dimming”: On/Off (pushbutton operated quickly) and PWM
50 kHz (pushbutton pressed for a longer time) with switch-off value memory
• Scene selection control: ALL On/Off, 6 scene memories
• Learning procedure for EnOcean transmitters, easy to operate

PTM 200 User Manual V1.1
• Learning procedure for EnOcean transmitters, easy to operate
Any further switching functions can be simply and flexibly implemented using the
serial interface output of the RCM 120 that is connected to a low-priced
microcontroller. The required output control logic can be easily programmed by the
user.
2.6 Learning of PTM 200 to RCM 110/120 Receivers
The PTM 200 can be easily made known to the receiver RCM 110 or RCM 120 that has been
set into learn mode through triggering a PTM 200 radio signal by operating the energy bow
when pressing either the O-rod or the I-rod of the desired channel A or B.
If the RCM 120 receiver is operated in mode 0 “Serial Interface”, telegrams from learned PTM
transmitters are signed (see RCM 110/120 User Manual).

PTM 200 User Manual V1.1
3.2 Construction of Suitable Switch Rockers
For CAD system development support, 3D construction data of the rocker model of
Chapter 3.1 are available from EnOcean (IGS data).
Using this data, the mechanical interface is fixed, and the shape and surface of the rocker(s)
can be changed according to requirements. Recommendation for suitable rocker material is
Ultradur B 4520 with a surface roughness of min. Ra 1.0 ym.
3.3 Device Mounting
For mounting the PTM 200 device into an application-specific case, the package outline
drawings of the device are roughly dimensioned in 1.4 Mechanical Interface.
If more detailed dimensioning data of the PTM 200 device case is necessary, 3D
construction data is available from EnOcean (IGS data).
3.4 Transmission Range
The main factors that influence the system transmission range are type and location of the
antennas of the receiver and the transmitter, type of terrain and degree of obstruction of the
link path, sources of interference affecting the receiver, and “dead” spots caused by signal
reflections from nearby conductive objects. Since the expected transmission range strongly
depends on these system conditions, range tests should categorically be performed before
notification of a particular range that will be attainable by a particular application.
The following figures for expected transmission range are considered by using the PTM 100
radio transmitter device and the RCM 110 or RCM 120 radio receiver device with the
preinstalled whip antennas and may be used as a rough guide only:
• 30 m for obstructed environment (e.g., through two brick walls inside a building)
• 300 m for unobstructed environment (“free field”)
Further notes to determine the transmission range within buildings are available as download
from www.enocean.comT.
