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) Energy bow

(2) Contact nipples

Figure 1: Electro-dynamic powered radio transmitter device PTM 200C
1.1
Basic Functionality
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.

Figure 10: Contact nipple designation
Radio signals of the PTM 200C 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
200C sends multiple-button code combinations:
ƒ
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.
ƒ
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!

PTM 200C 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:
ƒ
Minimal energy demand
ƒ
Possibility of operating hundred of senders within the same radio cell
ƒ
Maximum transmission reliability
ƒ
Wide transmission range
ƒ
Easy extensibility
ƒ
Suitable for uni- and bi-directional communication
ƒ
Flexibility for adaptation of different data structures and data quantities
ƒ
Data encryption option
2.3.1 Frequency range
The EnOcean PTM200C operates at 315.0 MHz.
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 .
2.3.3 Transmission timing
The transmission timing of the radio device PTM 200C 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 transmitters 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.

Construction of application specific Switch Rockers
For CAD system development support, 3D construction data is 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 polycarbonate (buckling resistant and wear-proof material). It is recommended
to apply teflon varnish in the areas of actuation.
Please note that the rockers should be of nonmetal for best transmission range!
Please also avoid plastic materials with conducting ingredients like graphite!
3.3
Device Mounting
For mounting the PTM 200C device into an application specific case, the package outline
drawings of the device are roughly dimensioned in chapter 1.4. If more detailed dimensioning data of the PTM 200C device case is necessary, 3D construction data is available from
EnOcean (IGS data).

Transmission Range
The main factors that influence the system transmission range are:
ƒ Type and location of the antennas of receiver and transmitter
ƒ Type of terrain and degree of obstruction of the link path
ƒ Sources of interference affecting the receiver
ƒ “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 in early project phases!
The following figures for expected transmission range are considered by using a PTM, or
STM transmitter device and the RCM radio receiver device with preinstalled whip antenna
and may be used as a rough guide only:
ƒ
ƒ
ƒ
ƒ
ƒ
Line-of-sight connections: Typically 30m range in corridors, up to 100m in halls
Plasterboard walls / dry wood: Typically 30m range, through max. 5 walls
Brick walls / aerated concrete: Typically 20m range, through max. 3 walls
Ferroconcrete walls / ceilings: Typically 10m range, through max. 1 ceiling
Fire-safety walls, elevator shafts, staircases and supply areas should be
considered as screening.
The angle at which the transmitted signal hits the wall is very important. The effective wall
thickness – and with it the signal attenuation – varies according to this angle. Signals
should be transmitted as directly as possible through the wall. Wall niches should be
avoided. Other factors restricting transmission range:
ƒ
ƒ
ƒ
ƒ
Switch mounted on metal surfaces (up to 60% loss of transmission range)
Hollow lightweight walls filled with insulating wool on metal foil
False ceilings with panels of metal or carbon fiber
Lead glass or glass with metal coating, steel furniture
The distance between EnOcean receivers and other transmitting devices such as computers, audio and video equipment that also emit high-frequency signals should be at least
1m.
A summarized application note to determine the transmission range within buildings is
available as download from www.enocean.com.

Field Intensity Meter EPM 100C
The EPM100C is a mobile field-intensity meter that helps the engineer to find the best installation positions for sensor and receiver. It can also be used to check disturbances in
links to already installed equipment. The EPM100C displays the field intensity of received
radio telegrams and interfering radio signals in the 315MHz range.
The simplest procedure for determining the best installation positions for
the radio sensor/receiver:
ƒ
ƒ
Person 1 operates the radio
sensor and generates pushbutton radio telegrams.
Person 2 checks the received
field intensity on the meter
display to find the optimal installation position.
