1 GENERAL DESCRIPTION

The pushbutton transmitter family PTM 21x from EnOcean enables the implementation of wireless switches and remote controls without batteries. The PTM 21x pushbutton transmitters are self-powered (no batteries) and therefore maintenance-free. The power is provided by a built-in electro-dynamic power generator.

The main application are wireless switches in smart buildings. Products based on PTM 21x modules can also be used in hermetically sealed systems or in remote (not easily accessible) locations.

PTM 21x devices are available in variants supporting the 868 MHz, 902 MHz and 928MHz radio interface protocols of EnOcean Alliance Radio Standard ERP 1 & ERP 2.

Figure 1 Electro-dynamic powered pushbutton transmitter module PTM 21x

With the major product update to the step code DC an additional NFC interface was added and the security mode option was extended to all PTM21x family members and frequencies.

1.1.1 Previous / other product variants

Previous versions of the PTM 21x product family (identified by step codes (DA and DB) contain only a subset of the functionality described in the document. Should you need information related to these products then please do not use this document as reference and refer to EnOcean support (support@enocean.com) for more details.

This document describes PTM modules with the EnOcean Radio Standard. For other radio standards PTMs (e.g. BLE, ZigBee) please visit the EnOcean Product page1 and select the product type to find the available information.

1.2 Basic Functionality

PTM 21x devices contain an electro-dynamic energy transducer which is actuated by a bow.

Figure 2 Drawing with highlighted energy bow

This bow is pushed by an appropriate push button, switch rocker or a similar construction mounted onto the device. An internal spring will release the energy bow as soon as it is not pushed down anymore.

When the energy bow is pushed down, electrical energy is harvested and a radio telegram is transmitted. Releasing the energy bow similarly generates energy which is used to transmit an another radio telegram.

USER MANUAL

PTM 210 / PTM 215 / PTM 215U / PTM 215J DC Step code and later

Figure 3 Energy bow released & pressed

It is therefore possible to distinguish between radio telegrams sent when the energy bow was pushed and radio telegrams sent when the energy bow was released. This makes it possible to distinguish between button press and button release actions.

By identifying these different telegrams types and measuring the time between pushing and releasing at the receiver, it is possible to distinguish between “Long” and “Short” push button presses. This enables simple implementation of applications such as dimming or blinds control.

The radio telegram used by PTM 21x devices identifies the status of the four contact nipples when the energy bow was pushed or released. This enables the implementation of up to two switch rockers or up to four pushbuttons.

Figure 4 Drawing with highlighted coding nipples

USER MANUAL

PTM 210 / PTM 215 / PTM 215U / PTM 215J DC Step code and later

All PTM 21x devices support two operating modes - a normal mode and a secure mode with rolling code encryption to enable use in secure applications.

Additionally, to the EnOcean Radio interface the PTM 215 modules include a NFC interface for device configuration. This NFC interface is powered by the NFC field of an NFC Reader or an NFC capable smartphone. This makes the communication with the PTM 215 modules possible even when the PTM is not being actuated. With a smartphone and an App e.g. EnOcean

Tool or with an NFC Reader and a PC tool e.g. EnOcean NFC Configurator it is therefore

possible to read information about the PTM module and write configuration parameters.

1.3 Typical Applications

PTM 21x modules are commonly used in the following areas:

 Building installation

 Industrial automation

 Consumer electronics

Key products include wall-mounted switches and handheld remote controls supporting up to two rockers or up to four pushbuttons.

Please find below two examples of an PTM module assembled into a white housing. The left example shows a double rocker application and the right a single rocker application. This is commonly used in the European market. A wide range of custom designs with different shapes, materials and colours can be used together with PTM modules as long they respect the standardized mechanical interface. Refer to the PTM module mounting instructions for details [1]. This allows customizable designs with well tested and promoted PTM modules.

2 FUNCTIONAL DESCRIPTION

2.1 Block Diagram

Figure 7 Block diagram of PTM 21x

Energy Generator / Energy Bow

Converts the motion of the energy bow into electrical energy. This is the main energy source for the operation of PTM Modules.

Energy Converter

Converts the energy of the energy generator into a stable DC supply voltage for the device electronics.

Energy Management

Secures energy supply of the module for the required period. The generator provides an burst of energy which needs to be conserved for the much longer period than the burst lasts.

Microcontroller

Determines the status of the contact nipples and the energy bow, encodes this status into a EnOcean Data telegram, if required it encrypts this data and computes the authentication signature, generates the proper radio telegram structure and sends it to the radio transmitter.

RF Transmitter

Transmits the data as a series of short EnOcean radio telegrams.

Contact Nipples

Via the 4 contact nipples the rockers or other custom plastics can code specific information into the radio telegram triggering different functions at the receiver.

USER MANUAL

PTM 210 / PTM 215 / PTM 215U / PTM 215J DC Step code and later

NFC Interface

The NFC interface represents the second communication interface of the PTM and it is designed for commissioning of the PTM device. Using the NFC module information, modes and runtime parameters can be read and in selected parameters also written.

2.2 Contact Nipples Assignment

PTM 21x devices provide four contact nipples. They are grouped into two channels (Channel A and Channel B) each containing two contact nipples (State O and State I). Resulting the nipples are referred to as: AO, AI, BO and BI.

The state of all four contact nipples is transmitted together with a unique device identification whenever the energy bow is pushed or released as a part of an EnOcean radio telegram. The exact encoding is defined in the EEP Profile. Which EEP is used is based on the Radio Standard (ERP1 or ERP2) and operating mode (normal or secure). See chapter 2.3 for details on used EEPs.

The picture below shows the arrangement of the four nipples and their designation:

Figure 8 Contact nipple designation

2.3 Available EnOcean Equipment Profiles

The (EnOcean Equipment Profile) EEP profile defines how the data inside the EnOcean telegram is encoded. It practically means how the nipples and energy bow state are represented

USER MANUAL

PTM 210 / PTM 215 / PTM 215U / PTM 215J DC Step code and later

in the radio telegram. Based on the EEP the receiver knows how to interpret telegrams received from a PTM module.

In contrast to sensors which usually support one profile at a time, the encoding of PTM module does not vary between profiles (RPS profiles) and it up to the receiver to decide how the data should be interpreted. The receiver can describe what action (switch on / off the light, dim up / down, move shutters, …) to take. This makes PTM modules very flexible to use.

The table below summarizes the EEP supported by the different members of the PTM 21x product family.

Table 2 Possible EEPs

For the normal mode profiles (Starting with F6) there is no EEP Teach-in message sent. For secure mode profile (starting D2) there is Secure Teach In. See chapter 3.2.3 for details.

TCM 515U and TCM 310U convert ERP2 profiles to EPR1 profiles internally. On the ESP3 interface the messages look like “ERP1”.

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.

Note that PTM 21x in will not send a data telegram when pressing 2, 3 or 4 nipple SBC and actuating the energy bow. This button combination is reserved for mode change. Please see chapter 3.3 for details.

3 OPERATING MODES

This chapter describes the standard “out of the box” behaviour of PTM 21x devices. This standard behaviour e.g. mode selection or secure teach-in telegram transmission can be altered by the NFC Interface. Please refer to the chapter 5.4 for details.

PTM 21x devices support two operating modes:

 Normal mode  Secure mode, this mode has two additional sub options

o Implicit RLC (legacy, not recommended) o Explicit RLC (recommended)

In production the PTM 21x is set into “normal mode” operation. This is therefore the “out of the box” behaviour of PTM 21x devices.

3.1 Normal Mode Operation

In normal mode, PTM 21x transmits telegrams in the EEP profile respectively defined by ERP1 or ERP2. Please refer to Chapter 2.3. for details.

In Normal mode, transmission of PTM 21x modules is secured by the secure concept includes unique transmitter IDs. This means EnOcean products cannot be configured to transmit with identical transmitter ID except for the special case of Base IDs.

3.2 Secure Mode Operation

While operating in secure mode, the PTM 21x sends secure telegrams in accordance to EEP D2-03-00. Please refer to Chapter 2.3. for details.

In secure mode, the PTM modules use advanced security protection with data encryption and message authentication. These mechanisms offer effective protection against a series of different attacks. One of the most concerning are Eavesdropping and Replay attacks.

Eavesdropping means somebody can receive and interpret the data correctly. Replay attacks means an intruder receives and records the message to be retransmitted (replayed) later in order to trigger an action.

An illustration of these attack scenarios are shown in the figure below.
