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 electrodynamic 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. (2) Contact nipples for switch rocker identification (1) Energy bow on both device sides Rotation axis for pushbuttons or switch rocker Figure 1: Piezo-radio transmitter device PTM 200 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. ©EnOcean GmbH, A. Anders Page 4 of 22 PTM 200 User Manual V1.1 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 (solarpowered wireless sensors), CTM (remote control) and TCM (bi-directional IT interface and repeater). 1.3 Features Overview Power supply: ......................................................... power generation by rocker pressing (Electro-dynamic Power Generator) Frequency:...................................................................................................868.3 MHz Transmission power:.................................................................................max. 10 mW Modulation type: ...................................................................................................ASK Data rate: ......................................................................................................120 kbps Channel bandwidth: ........................................................................................ 280 kHz Antenna:...................................................................................................... integrated Transmission range: ................................................................ approx. 300 m free field Telegram packet length (sub-telegram):................................................ 0.9 ms +/-5% No. of (redundant) packets: ....................................................... 3 within approx. 40 ms Number of channels: ................................................ 2 channels with 4 action states each (upper/lower contact nipple is pressed/released) Telegram type: ........................................................................................RPS of type 2 (allows interpretation of operating two buttons simultaneously) Device identifier: ............................................ individual 32-bit ID (factory programmed) ©EnOcean GmbH, A.

Power Converter Electronic converter unit for generating the device DC power supply Processor Converts the contact nipples’ status and pushed/released data from the power generator into a reliable and energy-efficient serial telegram structure. HF transmitter Sends the data in the form of a series of short radio signals. ©EnOcean GmbH, A. Anders Page 11 of 22 PTM 200 User Manual V1.1 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: STATE CHANNEL 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 multiplebutton 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! ©EnOcean GmbH, A. Anders Page 12 of 22 PTM 200 User Manual V1.1 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. ©EnOcean GmbH, A. Anders Page 13 of 22 PTM 200 User Manual V1.1 t Nominal values: 5 ms 10 ms 0...7,5ms at random Figure 11: PTM 200 radio timing 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.

Anders Page 14 of 22 PTM 200 User Manual V1.1 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 RCM 120 output switching functionalities (controlled by PTM radio signals) • Basic signal output function “pushbutton”: 1 channel • Basic signal output function “tubular motor control” (UP/DOWN with slat action): 1 or 2 channel ©EnOcean GmbH, A. Anders Page 15 of 22 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). ©EnOcean GmbH, A. Anders Page 16 of 22 PTM 200 User Manual V1.1 3. APPLICATIONS INFORMATION 3.1 Rocker Model For evaluating the PTM 200, a neutral model of a double-rocker is available from EnOcean that can be easily snapped onto the PTM 200 device case: Figure 14: Rocker Model for PTM 200 Figure 15: Rocker model snapped onto the device Please note that pressing the rocker sends a N-message, and releasing the rocker sends a Umessage. ©EnOcean GmbH, A. Anders Page 17 of 22 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. ©EnOcean GmbH, A.
