2 Functional 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 implementation 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 another 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.

3 Radio 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 preventing 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 respective 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 during 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 installations 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 receiver 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 connecting 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 disconnected 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 sufficient 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

4 PTM 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 possible 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 release)

◼ 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 subtelegrams.

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 currently 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 power 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+) connected 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.

5 Application information

5.1 Connection to ECO 200 energy harvester

PTM 535 can be connected to ECO 200 without soldering. ECO 200 provides contact springs which can directly be connected to the corresponding contact pads of PTM 535.

The contact pads on the bottom of the PCB are shown below (left). A second orientation where PTM 535 is rotated 180° with respect to ECO 200 is also possible as shown with dashed lines.

5.2 How to populate a teach-in button (for enhanced security mode)

PTM 535 provides two landing pads for a LRN button called SECURE and VCC_MODE. If a pushbutton is mounted then this will act as secure teach-in button. By pressing the button and triggering the ECO 200, the secure teach-in process is triggered, the module switches to secure mode and transmits a secure teach-in telegram.

To switch operation back to standard mode, the STANDARD and VCC_MODE pin must be connected. There is no push button option available for this step.

A drilling is positioned between the pads. This enables the possibility to mount also push buttons which have pressing point deeper than the PCB (better tactile handling) or are operated from the bottom.

Please see drawings of PTM 535 for detailed information and position of pads. The design of the pads was optimized for Compact High-speed Mounting Type (Surface Mount) SKQY Series switch from ALPS.

5.5 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 this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application.

The following figures for expected transmission range are considered by using a PTM 535 radio transmitter device and a TCM 310 / TCM 310U / TCM 410J radio receiver device with installed whip antenna and may be used as a rough guide only:

◼ Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls ◼ Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls ◼ Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls ◼ Ferroconcrete walls / ceilings: Typically 10 m range, through max. 1 ceiling ◼ Fire-safety walls, elevator shafts, staircases and supply areas should be considered

as screening.

The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoided.

Other factors restricting transmission range include:

◼ Switch mounted on metal surfaces (up to 30% loss of transmission range) ◼ Hollow lightweight walls filled with insulating wool on metal foil ◼ False ceilings with panels of metal or carbon fiber ◼ Lead glass or glass with metal coating, steel furniture

The distance between EnOcean receivers and other transmitting devices such as computers, audio and video equipment that also emit high-frequency signals should be at least

0.5 m

6 Regulatory information

PTM 535 has been tested according to standards for RED (European Union), FCC (United States), ISED (Canada) and ARIB (Japan) certification.

6.1 RED (European Union)

The Radio Equipment Directive (2014/53/EU, typically referred to as RED) replaces the old R&TTE directive from 1999 as regulatory framework for radio products in the European Union. All products sold to final customers after 12th of June, 2017 have to be compliant to RED.

At the time of writing, the text of the RED legislation was available from this link: http://eur-lex.europa.eu/eli/dir/2014/53/oj

Dolphin radio modules such as PTM 535 are components which are delivered to OEM manufacturers for their use in final or combined products.

It is the responsibility of the OEM manufacturer to demonstrate compliance to all applicable EU directives and standards. The attestation of conformity for PTM 535 serves as input to the declaration of conformity for the full product.

At the time of writing, guidance on the implementation of EU product rules – the so called “Blue Guide” – was available from this link: http://ec.europa.eu/DocsRoom/documents/18027/

Specifically within the new RED framework, all OEM manufacturers have for instance to fulfill the following additional requirements:

◼ Provide product branding (on the product) clearly identifying company name or

brand and product name as well as type, charge or serial number for market surveillance

◼ Include (with the product) documentation containing full postal address of the man-

ufacturer as well as radio frequency band and max. transmitting power

◼ Include (with the product) user manual, safety information and a declaration of con-

formity for the final product in local language

◼ Provide product development and test documentation upon request

Please contact an accredited test house for detailed guidance.

The maximum transmitting power of PTM 535 using a whip antenna is +5 dBm.
