1GENERAL DESCRIPTION
The pushbutton transmitter family PTM 21x from EnOcean enables the implementation of
wireless switches and remote controls without batteries. The PTM 21x pushbutton transmit-
ters 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 ([e-mail]) 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 page
1
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.

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 con-
trol.
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.

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 pos-
sible 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.

2.1 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.

NFC Interface
The NFC interface represents the second communication interface of the PTM and it is de-
signed 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 tele-
gram is encoded. It practically means how the nipples and energy bow state are represented

in the radio telegram. Based on the EEP the receiver knows how to interpret telegrams re-
ceived 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.

3OPERATING 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
oImplicit RLC (legacy, not recommended)
oExplicit 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 dif-
ferent 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.

Figure 9 Example of harmful attacking scenarios PTM Modules are protected from
For details on the secure mechanisms please refer to the security specification of the EnOcean
Radio Protocol [3] together with the examples given in the application note
4
.
Secure telegrams include a rolling code based on an incrementing counter (RLC) which guar-
antees that identical message content will be encrypted differently.
The counter can be:
Included in each data message - explicit (recommended)
Or
Not included in data messages –implicit (legacy, not recommended)
The counter value is also part of the teach-in telegram. The selection if the counter is implicit
or explicit is done via the NFC interface (see chapter 5.3.4.3) or special button combinations
at mode switching (see chapter 3.3).
There is no advantage in term of being “more secure” or “more protected” by using the
implicit mode over explicit or vice versa. The “protection level” and security mechanisms are
identical.
The RLC counter bit-size (24 bit explicit mode) practically ensures no “run over”will ever
occur and one RLC value is never reused during the PTMs lifetime twice. It is initialized to 0
at production.

PTM 210 / PTM 215 / PTM 215U / PTM 215J
DC Step code and later
The RLC counter is internally restarted to 0x0 once the AES key was changed via the NFC
interface.
After executing a factory reset (see chapter 3.4 for details), the PTM module returns to using
the factory set security key but does not reset the RLC counter associated with the key. The
last used RLC value associated with the factory security set key will be used.
3.2.1 Implicit RLC –legacy, not recommended
This mode is relevant only for the European market (868 MHz) because of certain legacy
receivers. For the J and U market 928 MHz and 902 MHz, there are no such legacy receivers
and thus this mode is completely deprecated in these markets.
The initial RLC counter value is transmitted from PTM 21x to the receiver only as part of the
teach-in telegram. Subsequent secure telegrams do not include it. Therefore, receiver has to
automatically increment its counter at every received telegram to keep it synchronized with
the PTM Module.
When telegrams are not received by the receiver then this may lead to a de-synchronization
of the RLC counter in the PTM module and the RLC counter in the receiver, i.e. the PTM
module counter will have a greater value than the receiver counter.
In order to mitigate this issue, the receiver will usually test the received rolling code against
a defined number –a window - of future expected rolling codes. If a RLC from within the
window can be validated then the receiver will resynchronize its counter automatically to the
new value.
The size of this rolling code window is defined on the receiver side.
For the correct function it is essential that the number of consecutive, non-received telegrams
does not exceed the size of this window.
3.2.2 Explicit RLC –recommended
This is the recommended secure mode for all frequencies and new applications.
In this mode the PTM module sends the RLC value as part of every data telegram. With
transmission of the RLC in every data telegram a desynchronization of the RLC counters
between receivers and transmitter like described above cannot happen.
The receiver uses the RLC value inside the radio telegram to decrypt and authenticate the
received message. The receiver has to check if the received RLC is higher than the last known
value and he does not have to apply any RLC window search mechanism.
3.2.3 Security Teach-in
The Security teach-in includes required information for the receiver to decrypt future data
communication. A security teach-in telegram is sent by PTM 21x after:

Executing the special button combination for secure mode 2x nipple SBC or 3x nipple
SBC –see chapter 3.3 for details.
Trigger through the NFC interface.
Key Secure Teach-in Parameters are specified as following:
Type of the Teach-in_info in the secure teach-in telegram (Teach_In_Info : Type)
is: 1-PTM.
Info of the Teach-in_info in the secure teach-in telegram (Teach_In_Info : Info)
is: 0-Rocker A / 1-Rocker B.
The opposite nipple (e.g. A0&AI or B0&BI) of the used 2xSBC or 3xSBC define the
rocker value (Rocker A or Rocker B) .
When then Secure Teach-in is triggered by NFC then the rocker is used which was
used to generate energy and transmit the Secure Teach-in telegram. If both or no
rocker was used, then Rocker A is coded.
SLF is set to:
oFor implicit RLC (legacy, not recommended)
24 bit MAC, VAES Encryption, 16 bit RLC, RLC no TX:
oFor explicit RLC (recommended)
24 bit MAC, VAES Encryption, 24 bit RLC, RLC TX
Due to the total length of the Security Teach-In message it needs to be separated in two
distinct telegrams. First part is transmitted at energy bow pressed and second at energy bow
released. For a successful transmission both parts need to be transmitted and received.
For more information on the structure of the teach-in telegram please refer to the EnOcean
Security specification [3].
If the teach-in process is not successful, please repeat the procedure. Due to the
enhanced telegram length of teach-in telegrams in secure mode only a single
teach-in sub-telegram is sent at every actuation (no redundancy).
3.3 Switching between modes
PTM 21x can be switched between normal mode and the secure modes by a special button
combination SBC. There are three types of SBC:
2 nipple SBC –pressing both nipples of a channel i.e. AI & AO or BI & BO.
This SBC is used to enter the secure mode with implicit RLC –legacy, not recom-
mended. The picture below shows both variants of this combination.

Figure 10 2 nipple SBC - channel A left, channel B right
3 nipple SBC –pressing any 3 nipples, which results in 4 different combinations.
This SBC is used to enter the secure mode with explicit RLC.
The picture below shows the possible options for this SBC.
Figure 11 3 nipple SBC - 4 different options
4 nipple SBC –pressing all 4 nipples.
This SBC is used to enter the normal mode and execute factory reset.
The Picture below illustrates this.

To execute a mode change using any of these SBC, the energy bow must be activated in a
defined sequence simultaneously. The SBC must be hold for the complete sequence.
The following transitions apply:

The secure teach-in second part is transmission is automatically executed by the PTM module
at the release action regardless what nipples are pressed or not pressed.
Before changing the operating mode please make sure to clear the device from all
receivers which have been teached-in with this device before. Otherwise the re-
ceiver will ignore the telegrams and the application will not work.
3.4 Factory Reset
The PTM module can execute a factory reset to return to the defined factory defaults. All
changes done via SBC or the NFC interface with the exception of the following will be reset:
Custom NFC message described in chapter 5.3.2.
The factory reset is executed with the 4 nipple SBC and simultaneously the sequence of 7x
times pressing & releasing the energy bow.
