Page 5: General Description
ECO 200 can be either mechanically connected using two contact pairs or connect- ed 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. -

Page 7: Functional Information
Figure 2 – Electro-dynamic powered radio transmitter device PTM 535Z Basic Functionality PTM 535Z devices contain an interface with two pair of signals (AC1 and AC2) used to con- nect an external energy generator (ECO 200). Having two contact pairs improves the me- chanical design flexibility. -
Page 8: Device Interface Signals
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. -

USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 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) -
Page 10: Hardware Configuration Interface
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. © 2016 EnOcean | www.enocean.com F-710-017, V1.0... -
Page 11: Hardware-Based Radio Channel Selection
2.6.2 Hardware-based radio channel selection By default, the radio channel used by PTM 535Z can be changed by the user during com- missioning 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. -
Page 12: 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 inter- nal antenna has to be cut in this case by removing capacitor CA. -
Page 13: Radio Channel Selection
HW selection (using configuration resistors, requires R1 to be populated) If configuration resistor R1 is populated then the radio channel used by PTM 535Z is fixed exclusively by the configuration resistors R3 … R6 as discussed in chapter 2.6.2. -
Page 14: Operation Modes
Commissioning mode is used to commission (learn, teach-in) PTM 535Z into a specific receiver or network. To do so, PTM 535Z will identify its capabilities and its security pa- rameters and – if required – change the radio channel it uses for telegram transmission. -
Page 15: Commissioning Mode
Commissioning mode provides two key functions: Transmission of a commissioning telegram in order to learn-in PTM 535Z into a network Radio channel selection in order to set the radio channel of PTM 535Z to that used by the network Figure 4 below shows the commissioning state chart used by PTM 535Z. -
Page 16: Entry Into Commissioning Mode
Commissioning mode is entered as soon as PTM 535Z detects an energy pulse from ECO 200 in “Press” direction and the LRN button is pressed. PTM 535Z will remain in commissioning mode as long as the LRN button is pressed when- ever ECO 200 is actuated in the “Press” direction. -
Page 17: Determining The Correct Radio Channel
It is the responsibility of the system designer to define a suitable feedback mechanism. 2.8.2.5 Storing the new radio channel and return to data mode If PTM 535Z has been successfully set to the desired radio channel then this radio channel has to be stored and operation should return to data mode. -

Page 19: Number Of Redundant Telegrams
2.10 Number of redundant telegrams For most telegram types, PTM 535Z will transmit the telegram more than once (redundant transmission) in order to increase transmission reliability. The timing of the individual tele- gram transmissions is random within a 5ms window. -

Page 38: Command Payload
PTM 535Z secure data telegrams can be authenticated via a signature. This signature is 4 byte long and only present if PTM 535Z operates in secure mode. It is calculated based on the private key (unique for each device), the data payload and a 4 byte sequence counter (which is incremented for each transmitted radio telegram).
