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.
PTM 535 / PTM 535U / PTM 535J – ENOCEAN TRANSMITTER MODULE 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.
PTM 535 / PTM 535U / PTM 535J – ENOCEAN TRANSMITTER MODULE Radio telegram format 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.
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;...
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.
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.
PTM 535 / PTM 535U / PTM 535J – ENOCEAN TRANSMITTER MODULE PTM 535 configuration interface The PTM 535 configuration interface consists of test points MP1- MP6. The function of these test points is summarized in Table 2 below. Signal...
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.
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.
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.
“Write to PTM 535” the modified configuration to additional module Quit Segger info window with no (details see PTM Config help)! 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 (for details, see PTM 535 Config help).
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.
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...
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 manu- facturers for their use in final or combined products.
