USER MANUAL

1 GENERAL DESCRIPTION

1.1 Basic functionality

PTM 535Z enables the realization of energy harvesting wireless switches for EnOcean systems communicating based on the 2.4 GHz IEEE 802.15.4 radio standard.

PTM 535Z is primarily intended for operation in conjunction with the EnOcean ECO 200 energy harvester. ECO 200 can be either mechanically connected using two contact pairs or connected to the electrical interface of PTM 535Z.

Upon detection of energy pulses from the ECO 200 harvester, PTM 535Z will read the status of additional input signals (on-board meander contact, external input signals) and report the result as IEEE 802.15.4 radio telegram. Both secure and normal transmission modes are supported.

PTM 535Z telegram format has been defined to maximize compatibility with a wide range of devices including such supporting the ZigBee Green Power standard. PTM 535Z radio telegrams are protected with AES-128 security based on a device-unique private key.

PTM 535Z contains a learn button (LRN) to send dedicated commissioning telegrams and to change the radio channel. Radio channel and security mode can also be selected using the hardware configuration interface consisting of six zero Ohm resistor pads (R1 … R6).

PTM 535Z provides a five pad external electrical interface with the following signals:

 External connection to ECO 200 (AC1 and AC2)  Two external input signals (IN1 and IN2)  Ground (GND)

PTM 535Z is mechanically compatible with the outline of existing PTM 33x modules. Figure 1 below shows PTM 535Z.

2 FUNCTIONAL INFORMATION

2.1 PTM 535Z Device Overview

The radio transmitter device PTM 535Z from EnOcean enables the implementation of wireless remote controls without batteries. Power is provided by an external power generator (typically ECO 200).

PTM 535Z device transmits data based on the 2.4GHz IEEE 802.15.4 standard. Key components of PTM 535Z are shown on the picture below.

Note that two contact pairs of AC1 and AC2 are located on the bottom side of the PCB and therefore not visible in the picture.

Figure 2 – Electro-dynamic powered radio transmitter device PTM 535Z

2.2 Basic Functionality

PTM 535Z devices contain an interface with two pair of signals (AC1 and AC2) used to connect an external energy generator (ECO 200). Having two contact pairs improves the mechanical design flexibility.

Upon detection of an energy pulse, PTM 535Z reports the status of the on-board meander contact (M1), the external input signals IN1 and IN2 and the polarity of ECO 200 action (press or release).

“Press” is defined within the scope of this document as a move of a mechanically connected

ECO 200 away from the PTM 535Z PCB while “Release” is defined as a move towards the PTM 535Z PCB

Radio telegrams are transmitted using the on-board antenna (ANT). An external antenna (EXT_ANT) can optionally be used, capacitor CA needs to be removed in that case. Radio telegram format has been defined to maximize compatibility with a wide range of devices including such supporting the ZigBee Green Power standard.

Table 1 below summarizes key elements and interface signals of PTM 535Z.

Table 1: PTM 535Z key elements and interface signals

The PTM 535Z device interface is described in more detail below.

2.4 Power supply

PTM 535Z is intended to be supplied by a connected ECO 200 kinetic energy harvester. ECO 200 can be connected to PTM 535Z in the following ways:

 Mechanical connection to one of the two pairs of AC1 / AC2 pads

Use of a suitable mechanical design is required to reliably fixate the ECO 200 contacts with the AC1 / AC2 connection pads

 Electrically connected using the AC1 / AC2 signals of the external interface

Figure 3 below illustrates the mechanical connection between an ECO 200 kinetic energy harvester and PTM 535Z.

Note that two pairs of contacts are provided by PTM 535Z to enable two orientations of ECO 200 (spring facing down = red lines / spring facing up = yellow lines) depending on the requirements of the customer mechanical design.

2.5 Input signals

PTM 535Z data transmits telegrams indicating the status of the following input signals:

 ECO 200 action direction (press or release)

Press indicates a move away from the PCB (and the ECO 200 contacts) Release indicates a move towards the PCB (and the ECO 200 contacts)

 On-board meander contact (M1)

This meander contact is intended for use with a conductive rubber button and is considered to be active if it is closed. Contact EnOcean for reference on suitable rubber contact mats if required.

 External input signals (IN1 and IN2)

PTM 535Z provides and internal pull-up resistor on these signals. These inputs are considered active if they are connected to Ground (GND).

USER MANUAL V1.0

PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE

2.6 Hardware configuration interface

PTM 535Z provides a hardware configuration interface based on six zero Ohm resistor footprints (R1 … R6).

Populating these resistors allows customer-specific adaption of the following parameters:

 Hardware-based security mode selection

 Hardware-based radio channel selection

2.6.1 Hardware-based security mode selection

By default, PTM 535Z transmits securely authenticated data telegrams based on AES128 encryption standard using a 16 byte device-unique secret key and a 4 byte sequence counter.

For certain applications it might be desirable to transmit data telegrams without sequence counter and device security key / telegram signature. PTM 535Z can be configured to do so by populating configuration resistor R2.

2.6.2 Hardware-based radio channel selection

By default, the radio channel used by PTM 535Z can be changed by the user during commissioning as described in chapter 2.8.2.3.

For certain applications it is desirable to pre-configure the radio channel in a way that it cannot be modified by the user.

This can be achieved by populating configuration resistor R1. If this resistor is populated then the radio channel used by PTM 535Z will exclusively be determined by configuration resistors R3 … R6 as shown in Table 3 below.

Using the LRN button, the user will trigger the transmission of a commissioning telegram, but he cannot modify the radio channel.

2.7 Radio interface

2.7.1 Antenna

PTM 535Z transmits data based on an on-board PCB antenna (ANT). An external 50Ω whip antenna connected to the EXT_ANT pin can alternatively be used. Connection to the internal antenna has to be cut in this case by removing capacitor CA.

Please check with EnOcean if you intend to use an external antenna.

2.7.2 Supported Radio Channels

PTM 535Z supports all sixteen IEEE 802.15.4 radio channels in the 2.4 GHz band (channels 11 … 26 according to IEEE 802.15.4 notation).

Table 4 below shows the correspondence between channel number and channel frequency (in MHz).
