2Functional description

2.1 Functional Principle

PTM 535 is designed to be powered by an ECO 200 kinetic energy harvester from EnOcean.

PTM 535 can be mechanically connected to the contact springs of ECO 200 by means of its

integrated PCB contacts.

PTM 535 provides 4 digital input pads and two PCB meander structures allowing the imple-

mentation of push button functions either via external connection or via conductive rubber

pads.

When the ECO 200 harvester generates an energy pulse or when power is supplied by an-

other source then PTM 535 determines the polarity of the energy pulse (push or release

direction), and the operating status of the digital inputs and encodes this information in an

RF telegram.

The communication mode (enhanced security communication or standard communication)

can be selected using the SECURE and STANDARD input pins or the LRN button (which is

not mounted by default). Default communication mode is STANDARD.

2.2 Block diagram

Figure 2 below shows the block diagram of PTM 535.

2.3 Interface pin layout

Figure 3 below shows the pin out and external interfaces of PTM 535 as seen from the top

(component side). Items marked in green are on the component side while items in grey

are on the bottom side.

In addition to the 16 boundary contacts, PTM 535 provides the following contact points:

◼Meander contact A0

◼Meander contact A1

◼Connection for whip antenna RF_WHIP

◼Footprint for LEARN button (connecting VCC and SEC)

◼AC1 / AC2 power supply connection to ECO 200 harvester

(two contact pairs at the PCB bottom side to support different ECO 200 orientation)

3Radio telegram format

3.1 Standard mode

In standard configuration, PTM 535 transmits the same telegram type as the PTM 210

pushbutton module. The telegram information is encoded within a 7 byte RPS telegram as

shown in Figure 4 below.

Figure 4 –PTM 535 telegram format

This telegram format uses the following fields:

◼Telegram type (RORG, 1 byte)

The telegram type is always 0xF6 indicating an RPS telegram

◼Switch data (DATA, 1 byte)

This field encodes the buttons that have been pressed. The encoding depends on the

number of buttons that have been pressed.

◼EnOcean Unique Radio IO (EURID, 4 byte)

This field contains the ID which uniquely identifies each EnOcean products

◼Switch status (STATUS)

This field encodes certain properties of the telegram as shown in below.

The STATUS field identifies the message type (U-Message or N-Message) as well as the

repeater level (original telegram, 1 hop repeated, 2 hop repeated) as shown in Figure 5

below.

Figure 5 –STATUS field encoding

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

If one or two buttons are pressed, then the button status is transmitted using a so-called

N-Message. The DATA field format of such N-Message is shown in Figure 6 below.

Figure 6 –DATA field encoding for N-Messages (one or two button presses)

If either no button is pressed (only the ECO 200 is actuated), three buttons are pressed or

four buttons are pressed then the button status is transmitted using a so-called U-Message.

The DATA field format of such N-Message is shown in Figure 7 below.

Figure 7 –DATA field format for U-Messages (no, three or four button pressed)

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

3.2 Enhanced security mode

While operating in enhanced security mode, PTM 535 sends secure telegrams in accordance

to EEP D2-03-00 as specified in EnOcean Equipment Profiles. For more details refer

to http://www.enocean-alliance.org/eep/.

These telegrams include a rolling code based on an incrementing counter which guarantees

that identical message content will be encrypted differently for each telegram thus prevent-

ing replay attacks.

The initial counter value is transmitted from PTM 535 to the receiver as part of the teach-in

telegram when entering secure mode. Subsequent secure telegrams do not specify this

counter value; therefore sender and receiver have to automatically increment their respec-

tive counters for each secure telegram to keep them synchronized.

When telegrams are not received by the receiver this may lead to a de-synchronization of

transmitter and receiver counters, i.e. the transmitter counter will have a greater value

than the receiver counter.

In order to prevent failure, the receiver will usually test the received rolling code against a

defined window of future expected rolling codes and –if successful - resynchronize its

counter automatically. The size of this rolling code window is defined on the receiver side.

It is important that the amount of consecutive, non-received telegrams does not exceed the

side of this window.

For more details please refer to http://www.enocean.com/en/security-specification/.

The rolling code is not transmitted with every telegram. It is only transmitted dur-

ing teach-in. Afterwards the receiver has to increase the counter autonomously for

each received message.

It is strongly recommended to use PTM 535 in secure mode only in fixed installa-

tions with safe radio distance to avoid de-synchronization of sender and receiver.

De-synchronization will occur if PTM 535 is operated outside the range of the re-

ceiver consecutively more often than the size of the rolling code window defined

on the receiver.

The same may apply if consecutive telegrams are lost on the receiver side due to

power interruptions.

In these cases it is necessary to set the receiver in LRN mode and teach-in the

device again.

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

3.3 Switching between operation modes

PTM 535 can be switched from standard mode (default) to enhanced security mode by con-

necting SECURE with VCC_MODE (see chapter 3 for details) and triggering the ECO 200.

Upon entry into enhanced security mode, a teach-in telegram is sent by PTM 535. The type

of the teach-in telegram (Teach_In_Info : Type) is: 1-PTM.

PTM 535 will continue to transmit secure teach-in telegrams until the SECURE pin is discon-

nected from the VCC_MODE pin.

The secure teach-in message has to be transmitted as two consecutive telegrams due to its

payload size. Therefore, the ECO generator has to be triggered twice in order to transmit a

complete secure teach-in message. It is not required that the two contacts (SECURE and

VCC_MODE) remain connected throughout the transmission of both messages. It is suffi-

cient to connect them while actuating the ECO energy generator the first time.

For more information on the structure of the teach-in telegram please refer to chapter 4.2

of http://www.enocean.com/en/security-specification/.

PTM 535 can be switched from secure mode to normal mode by connecting STANDARD with

VCC_MODE and triggering the ECO 200. Then disconnect the pins.

Before changing the operating mode please make sure to clear the device from all

receivers which have been taught to work with this device before. Otherwise the

receiver will ignore the telegrams and the application will not work.

3.4 Transmission timing

The setup of the transmission timing allows avoiding possible collisions with data packages

of other EnOcean transmitters as well as disturbances from the environment. With each

transmission cycle, 3 identical subtelegrams are transmitted within 40 ms.

The transmission of a subtelegram lasts approximately 0.7 ms. The delay between the

three transmission bursts is affected at random.

PTM 535 transmits in secured mode 2 identical subtelegrams with length of ~ 1.3 ms

PTM radio modules are designed for manual button operation. The actuation rate

should therefore be limited to no more than 5 actuations per second.

For higher actuation rates, PTM radio modules might temporarily stop operation

and will restart operation after a period of 2 seconds without operation.

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

4PTM 535 configuration

PTM 535 provides a configuration interface that can be used to configure certain device

parameters.

4.1 PTM 535 configuration parameters

The following parameters can be configured for PTM 535 (868.300 MHz):

◼Content of the radio telegrams

This can be configured for each of the 32 possible input combination (A0, A1, B0,

B1, direction of ECO movement)

◼Default operation mode

This can be standard (default) or enhanced security. Changing the mode is still pos-

sible using the HW mechanism described in chapter 3.3

◼Secure teach-in telegram transmission

The secure teach-in telegram transmission can start only when the ECO 200 is

pressed, only when the ECO 200 is released or at any ECO 200 action (press or re-

lease)

◼Number of secure subtelegrams

If PTM 535 is powered by an ECO 200 harvester and operating in enhanced security

mode then it will always transmit 2 subtelegrams.

If PTM 535 is powered by another energy source such as a battery and operating in

enhanced security mode, then it can be selected if it should transmit 2 or 3 subtele-

grams.

Note that configuration is currently only supported for PTM 535 (868.300 MHz).

Configuration of PTM 535U (902.875 MHz) and PTM 535J (928.350 MHz) is cur-

rently not supported.

4.4 Connection between Segger J-Link and PTM 535

PTM 535 has to be connected to the Segger J-Link connector for configuration. Figure 9

below shows the pin-out of the Segger J-Link connector.

Figure 9 –Segger J-Link connector pin-out

Two approaches can be used to connect Segger J-Link and PTM 535 depending on the pow-

er supply of PTM 535 during configuration. Both approaches are described below.

4.4.1 Segger power supply (6-Pin interface)

Supplying power by Segger J-Link to PTM 535 is the recommended approach. It requires a

6 pin test interface.

In this case, power is supplied by Segger J-Link to PTM 535 via PTM 535 MP5 (V+) con-

nected to Segger Pin 19. The “5V Target Power Supply” option has to be activated at the

Segger user interface. We recommend checking available voltage supply.

The required connections are shown in Figure 10 below.

Figure 10 –6-Pin configuration interface (Power supplied by Segger)

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

4.4.2 External power supply (4 pin configuration interface)

This approach allows you to use a 4 needle test adapter instead of a 6 needle adapter.

Existing 4 needle adapters built for PTM 335 can be reused.

It requires to supply PTM 535 by an external power supply (2.0 - 3.3 V) connected to PTM

535 MP1 and to Segger VTref (IO voltage reference). The external power supply ground has

to be connected to PTM 535 MP2 (GND) and Segger GND.

The required connections are shown in Figure 11 below.

Figure 11 –4-Pin configuration interface (external power supply)

USER MANUAL

PTM 535 / PTM 535U / PTM 535J –ENOCEAN TRANSMITTER MODULE

4.5 Required tools

The following tools are required to configure PTM 535:

◼Needle adapter

Suitable adapter to contact test points as described in the previous chapter.

EnOcean can provide a mechanical design example upon request.

◼Debugger / Programmer

J-Link Plus or higher from Segger is required, see:

https://www.segger.com/products/debug-probes/j-link/models/j-link-plus/

◼J-Link Software and Documentation Pack

https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack

◼PTM 535 Configuration Suite

http://www.enocean.com/en/download/

Please check PTM 535 Config help for a detailed description of the program usage.

PTM 535 Configurator uses Segger tools to communicate with the radio chip. If a

window pops up “to unlock” the device you must select NO (details see PTM 535

Config help). Due to radio approval requirements a wrong configuration will lead

the module to stop radio transmission.

Radio module configuration is only possible with the EnOcean PTM 535 Configu-

rator tool. Follow exactly the below written sequence to chance PTM 535 config-

uration. Due to radio approval requirements, a wrong configuration will lead the

module to stop radio transmission.

Additional care has to be taken to configure correct values for DATA and STATUS

fields. Otherwise PTM 535 might not work properly together with repeaters or

receivers.
