USER MANUAL PTM 535Z 2.4 GHz Pushbutton Transmitter 1 1.1 GENERAL DESCRIPTION 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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 1.2 Technical data Antenna Integrated PCB antenna External 50 Ohm whip antenna (optional) IEEE 802.15.4 (2.4 GHz) Radio Standard Supported Radio Frequency Range IEEE 802.15.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2 2.1 FUNCTIONAL INFORMATION 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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.3 Device interface signals Table 1 below summarizes key elements and interface signals of PTM 535Z.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.
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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.7.3 Radio channel selection The radio channel used by PTM 535Z can be selected in two ways: User selection (using LRN button, default mode) If configuration resistor R1 is not populated (default) then the radio channel can be selected by the user as described in chapter 2.8.2.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.8 Operation modes PTM 535Z can operate in two modes: Data mode Data mode is used to transmit data telegrams reporting the status of PTM 535Z button inputs Commissioning mode Commissioning mode is used to commission (learn, teach-in) PTM 535Z into a specific receiver or network.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.8.2 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.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.8.2.1 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 whenever ECO 200 is actuated in the “Press” direction. 2.8.2.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.8.2.4 Determining the correct radio channel The user requires system feedback to determine if the correct radio channel has been reached. Several methods are possible for that, including: Feedback from the device into which PTM 535Z is learned in E.g. blinking a status light, toggling a connected load, moving a motor etc.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 2.9 Security modes PTM 535Z can operate in two security modes: Secure mode (default, R2 not populated) PTM 535Z operates in secure mode by default using AES128 security for data telegrams. Security is based on a random, device-unique security key which is generated during the production of the device.
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 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 telegram transmissions is random within a 5ms window. The number of telegram transmissions is limited by the available energy and therefore dependent on the telegram length (number of bytes to be transmitted).
USER MANUAL V1.0 PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE 3 IEEE 802.15.4 Frame Structure PTM 535Z transmits radio telegrams in the 2.4 GHz band according to IEEE 802.15.4 frame structure.
