  • Page 4: General Description

    03925 pushbutton transmitters are self-powered (no batteries) and fully maintenancefree. They can therefore be used in all environments including locations that are difficult to reach or within hermetically sealed housings. The required energy is generated by an electro-dynamic energy transducer actuated by an energy bow located on the left and right of the module.

    2.3 User Interface 03925 devices provide four button contacts. They are grouped into two channels (Channel A and Channel B) each containing two button contacts (State O and State I). The state of all four button contacts (pressed or not pressed) is transmitted together with a unique device identification (48 Bit device ID) whenever the energy bow is pushed or released.

  • Page 6: Telegram Transmission

    03925 transmits Bluetooth technology Low Energy (BLE) advertising telegrams within the 2.4 GHz radio frequency band (2402MHz … 2480MHz). By default, 03925 will use the three BLE advertising channels (BLE Channel 37, 38 and 39) defined for transmission. The transmission of a radio telegram on these three advertising channels is called an Advertising Event.
  • Page 7 CH_REG2 and CH_REG3. The 03925 telegram will in this mode be transmitted on the radio channel selected by CH_REG1 first, immediately followed by a transmission on the radio channel selected by CH_REG2 and a transmission on the radio channel selected by CH_REG3.

    The structure of 03925 static addresses is as follows: ■ The upper 2 bytes of the source address are used to identify the device type and set to 0xE215 for all 03925 devices. These two bytes cannot be changed. ■ The lower 4 bytes are uniquely assigned to each device. They can be changed using the NFC configuration interface as described in chapter 6.7.3 Figure 10 below illustrates the static address structure used by 03925.

    4.4.2 Private resolvable source address mode For some applications it is desirable to modify (rotate) the source address used by 03925 in order to prevent tracking of its radio transmissions. At the same time, each 03925 device must remain uniquely identifiable by the receiver.

    4. Calculate security signature In 03925, the type of action (Press Action or Release Action) is indicated by Bit 0 (Energy Bar). If a button contact has been actuated during Press Action or Release Action then this is indicated by the according status bit set to ‘1’.

    ■ Device identification The receiver needs to know how to uniquely identify this specific 03925 device. This is achieved by using a unique 48 Bit ID (Source Address) for each 03925 device as described in chapter 4.4. In addition, up to 4 byte of Optional Data can be configured as described in chapter 6.7.6.
  • Page 13 Figure 18 – Button sequence to enter radio-based commissioning mode To enter commissioning mode, start by selecting one button contact of 03925. Any button of 03925 (A0, A1, B0, B1) can be used. This button is referred to as Button_X in Figure 18 above.

  • Page 14: Factory Reset

    03925 can be reset to its default settings by means of a factory reset. This ensures that 03925 can be reset to a known configuration in case the PIN for the NFC access has been lost or NFC access is not possible for other reasons.

    6. NFC interface 03925 implements NFC Forum Type 2 Tag functionality as specified in the ISO/IEC 14443 Part 2 and 3 standards using an NXP NT3H2111 Mifare Ultralight tag. This NFC functionality can be used to access (read and write) the 03925 configuration memory and thereby configure the device as described in the following chapters.
  • Page 16 NFC interface 6.2.2 IDLE state IDLE is the waiting state after a Power-On Reset (POR), i.e. after the NFC tag has been introduced into the magnetic field of the NFC reader. The NFC tag exits the IDLE state towards the READY 1 state when either a REQA or a WUPA command is received from the NFC reader. REQA and WUPA commands are transmitted by the NFC reader to determine whether any cards are present within its working range.

    ■ Public data ■ Protected data In addition to that, 03925 maintains a private configuration memory region used to store default parameters and confidential information which is not accessible to the user. Figure 24 below illustrates the configuration memory organization used by 03925.

    Product ID and Manufacturer ID can be configured by the customer as required to identify his 03925 based product, see chapter 6.6.5 ■ 03925 Static Source Address This is a 4 byte field used to identify the static source address used by 03925, see chapter 4.4.1. Each 03925 is pre-programmed with an individual staticsource address.

    6.6.3 Source Address Write register The Source Address Write register is 4 byte wide and can be used to modify the lower 32 bit of the 03925 Static Source Address. The upper 16 bit of the 03925 Static Source Address are always fixed to 0xE215 to identify the device type.

    6.6.10 Customer Data 03925 allocates 64 pages (256 byte) for customer data that can be read and written via the NFC interface in protected mode. The main intention is to enable storing OEM-specific information such as product type, revision, date code or similar. There is however no restriction (other than the maximum size of 256 byte) on the type of content that can be stored in this memory region.

    (for how long will the receiver scan within each scanning cycle). 03925 transmits the advertising events with a pause interval of 20 ms between two transmissions. The transmission of the advertising event itself requires approxi- mately 1 ms per radio channel (meaning approximately 3 ms in total when using 3 radio channels) which means that the total time between the start of two advertising events is approximately 23 ms.
