1 GENERAL DESCRIPTION
The radio transmitter device PTM 210 / PTM 210C from EnOcean enables the implementa­tion of wireless remote controls without batteries. Power is provided by a built-in electro­dynamic power generator. The PTM 210 / PTM 210C device serves the 868 MHz / 315 MHz air interface protocol of EnOcean.
(1) Energy bow on both device sides
(2) Contact nipples for switch rocker identification
Rotation axis for pushbuttons or switch rocker
Electro-dynamic powered radio transmitter device PTM 210
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 tran smitted 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.

1.2 Typical Applications
Building installation Industrial automation Consumer electronics
Key applications are wall-mounted flat rocker switches with 1 or 2 rockers, as well as hand­held remote controls with up to 4 single pushbuttons. Because the RF transmitters are self­powered (no batteries), maintenance-free RF systems are possible.

Contact nipple designation
Radio signals of the PTM 210 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 210 sends multiple­button code combinations:
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.
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 Transmission timing
The transmission timing of the radio device PTM 210C 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 40 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 (PTM 210C only).

Example of a well suited antenna
3.2 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 inte rface 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 210 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 device case is necessary, 3D construction data is available from EnOcean (IGS data).
Mounting the module back side on metal surfaces directly or mounting the module
into metal frames can lead to up to typical 30% loss of transmission range within a building.

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 this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application.
The following figures for expected transmission range are considered by using a PTM, a STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled whip antenna and may be used as a rough guide only:
Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls Ferro concrete walls / ceilings: Typically 10 m 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:
Switch mounted on metal surfaces (up to 30% loss of transmission range) Hollow lightweight walls filled with insulating wool on metal foil False ceilings with panels of metal or carbon fibre 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
0.5 m
A summarized application note to determine the transmission range within buildings is available as download from www.enocean.com

4 AGENCY APPROVALS
4.1 CE Approval (PTM 210 only)
The devices bear the EC conformity marking CE and conform to the R&TTE EU-directive on radio equipment. The assembly conforms to the European and national requirements of electromagnetic compatibility. The conformity has been proven and the corresponding documentation has been deposited at EnOcean. The PTM devices can be operated without notification and free of charge in the area of the European Union, and in Switzerland. The following provisos apply:
EnOcean RF devices must not be modified or used outside their specification limits. EnOcean RF devices may only be used to transfer digital or digitized data. Analog speech
and/or music are not permitted.
The final product incorporating EnOcean RF devices must itself meet the essential re-
quirement of the R&TTE Directive and a CE marking must be affixed on the final product and on the sales packaging each. Operating instructions containing a Declaration of Con­formity has to be attached.
If transmitters are used according to the regulations of the 868.3 MHz band, a so-called “Duty Cycle” of 1% per hour for each transmitter must not be exceeded. Permanent trans­mitters such as radio earphones are not allowed. For conventional applications, it must be ensured that the PTM 210 radio device is not operated more than 6000 times within one hour (one operation: energy bow is pressed and released). Within this calculation, the ex­traordinary short telegram length is considered including three subtelegrams. Also a toler­ance of 5% in the telegram length is included.
