As far as patents or other rights of third parties are concerned, liability is only assumed for modules, not for the described applications, processes and circuits. EnOcean does not assume responsibility for use of modules described and limits its liability to the replacement of modules determined to be defective due to workmanship. Devices or systems containing RF components must meet the essential requirements of the local legal authorities.
ZigBee Green Power standard is transmitted. This radio tel- egram transmits the operating status of all four contact nipples at the moment when the energy bow was pushed down or released. PTM 215ZE telegrams are protected with an AES- 128 signature based on a device-unique private key.
Figure 2 – Electro-dynamic powered pushbutton transmitter module PTM 215ZE Functional Principle PTM 215ZE devices contain an electro-dynamic energy transducer which is actuated by an energy bow (1). This bow is pushed by an appropriate push button, switch rocker or a similar construction mounted onto the device.
Transmits the data in the form of a series of short ZigBee Green Power radio telegrams using the integrated antenna In addition, PTM 215ZE contains an integrated NFC interface according to ISO14443 that can be used to configure device parameters.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module User Interface PTM 215ZE devices provide four button contacts. They are grouped into two channels (Chan- nel A and Channel B) each containing two button contacts (State O and State I).
ZigBee Green Power data and commissioning telegrams. Radio Channel Parameters PTM 215ZE supports all sixteen IEEE 802.15.4 / ZigBee Green Power radio channels in the 2.4 GHz band (channels 11 … 26 according to IEEE 802.15.4 notation) which can be selected as described above.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module Telegram Structure PTM 215ZE transmits radio telegrams in the 2.4 GHz band according to the IEEE 802.15.4 frame structure using a ZigBee Green Power compliant payload. Note that the byte order used by these standards is little endian. This means that for multi- byte structures (such as 2 byte, 4 byte or 8 byte fields) the least significant byte (LSB) is transmitted first.
The IEEE 802.15.4 MAC Header contains the following fields: Frame Control Field (2 byte) The Frame Control Field is set to 0x0801 in all PTM 215ZE telegrams in order to identify them as data telegrams with short addresses based on version IEEE 802.15.4-2003 Sequence Number (1 byte) ...
(sending the same telegram again) Command (1 byte) The Command field is a one byte field which identifies the state of the PTM 215ZE contacts. For the encoding please refer to Table 2 below. Telegram Signature (4 byte) ...
3.3.1 Button Contact Encoding Table 2 below shows the supported single and dual button contact actions of PTM 215ZE together with the encoding used for the transmission. In this table, the meaning of “0” and “1” is the following for press and release events: “0”...
In order to avoid message replay (capture and retransmission of a valid message), it is re- quired that the receiver tracks the value of the sequence counter used by PTM 215ZE and only accepts messages with higher sequence counter values (i.e. not accepts equal or lower sequence counter values for subsequent telegrams).
The security key required for the telegram authentication can be obtained in two ways: Product DMC code Each PTM 215ZE device contains a product label with a DMC code that identifies the Source ID and the Private Security Key used by this device, see below. Commissioning telegram ...
Transmission of a commissioning telegram in order to learn-in PTM 215ZE into a network Radio channel selection in order to set the radio channel of PTM 215ZE to that used by the network These functions are described subsequently in more detail.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module To enter commissioning mode, start by selecting one button contact of PTM 215ZE. Any contact of PTM 215ZE (A0, A1, B0, B1) can be used. This contact is referred to as ButtonX in Figure 10 above.
The Command field is set to 0xE0 to identify this command as commissioning command Device Type (1 byte) The Device Type field is set to 0x02 to identify PTM 215ZE as ON / OFF switch Device Options (2 byte) ...

PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module Radio Channel Adjustment The radio channel used by PTM 215ZE can be changed whenever PTM 215ZE is in commis- sioning mode. Refer to chapter 3 for a summary of the supported radio channels.
It is the responsibility of the system designer to define a suitable feedback mechanism. Radio Channel Storage And Return To Data Mode If PTM 215ZE has been successfully set to the desired radio channel, then this radio channel has to be stored and operation should return to data mode.
14443 Part 2 and 3 standards using an NXP NT3H2111 Mifare Ultralight tag. This NFC functionality can be used to access (read and write) the PTM 215ZE configuration memory and thereby configure the device as described in the following chapters.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module Device Integration PTM 215ZE is designed for integration into button or rocker-based switches with manual activation (press and release by user input). It implements the established PTM 2xx mechan- ical form factor and can therefore be used with a wide variety of existing designs.

PTM 215ZE is powered by the electromagnetic generator ECO 200. For proper function there has to be a keep out zone of 60mm for magnets or ferromagnetic materials around the center of PTM 215ZE.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module Device Label Each PTM 215ZE module contains a product label identifying key parameters such as manu- facturing date, device ID and an optically readable code that can be used to automatically scan device parameters as shown in Figure 23 below.
PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module Regulatory Information PTM 215ZE has been certified according to FCC (US), ISED (Canada) and RED (Europe) reg- ulations. Changes or modifications not expressly approved by EnOcean could void the user's authority to operate the equipment.
