    902.875 MHz radio systems in the US / Canada and 928.35 MHz radio systems in Japan. Note that EnOcean radio transceivers such as TCM 310 or TCM 515 will by default convert received ERP1 and ERP2 telegrams into the same RADIO_ERP1 packet type so that the dif- ference between ERP1 and ERP2 is transparent to the connected host.

  • Page 93: Erp2 Telegram Format

    ◼ Subtelegrams EnOcean radio systems use the concept of redundant subtelegrams in order to increase the communication reliability. In addition to using redundant transmissions, first and second level repeaters can be used to increase communication distance and reliability as described in chapter 6.

  • Page 94: Subtelegram Timing

    20 ms and 29 ms. Both first and second level repeaters do not transmit a third subtelegram. The standard sub- telegram timing is summarized in Table 40 below. It is used both by TCM 515 and TCM 515U. Time Offset [ms]...

    USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE A.3.2 TX maturity time The maximum time between the request for transmission and the end of transmission of all subtelegrams is called the TX Maturity Time. In radio systems using standard subtelegram timing, the TX maturity time is 40 ms because the transmission of the last telegram will start no later than 39 ms after the transmission request.

  • Page 96: Addressing

    Telegrams where the intended receiver is designated are called Addressed Data Tele- gram or ADT in short. Telegrams where the intended receiver is not designated are called Broadcast Telegrams. Different types of addresses can be used to designate sender and receiver of an EnOcean radio telegram. A.4.1 Address types...

  • Page 97: Eurid (Radio Id)

    A.4.4 Base ID Normally, EnOcean devices will use their own EURID in order to identify themselves as the originator of transmitted telegrams. For very specific use cases, they can instead choose to use an address (ID) from within a defined range of 128 addresses. These 128 addresses are called the Base ID Range of the device.

  • Page 98: Data Payload

    TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE Data payload EnOcean radio systems encode the data using so called EEP (EnOcean Equipment Profile). Each transmitter might choose one (or sometimes several) EEP for data transmission de- pending on the type of transmitted data.

  • Page 99: Common Rorg

    TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE A.5.2 Common RORG Within EnOcean radio telegrams, the RORG field identifies the telegram type as described in the previous chapter. Table 42 below lists common RORG used for communication in EnOcean systems.

  • Page 100: Data Payload Size

    TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE A.5.3 Data payload size The maximum telegram data payload size used by EnOcean radio telegrams is 14 byte of data payload for the case of standard broadcast telegrams. For the case of standard ad- dressed telegrams, the maximum length of the data payload is 9 byte.

  • Page 101: Telegram Chaining For Broadcast Telegrams

    USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE A.6.1 Telegram chaining for broadcast telegrams Chained broadcast telegrams can be identified by the R-ORG 0x40 (CDM). The first telegram in a chain (with IDX = 0b000000) uses the CHAIN_LEN field to specify the total length of the DATA payload that is transported by this chain.

    USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE Subsequent telegrams in a chain of addressed telegrams omit both the CHAIN_LEN and the RORG field as shown in Figure 34 below.

  • Page 103: Telegram Chaining For Addressed Secure Telegram (Adt Sec_Cdm)

    The last SEC_CDM telegram might therefore be split into two ad- dressed SEC_CDM telegrams due to the addition of the RORG and DESTINATION EURID ad- dressing fields resulting in a telegram size larger than the maximum size of EnOcean radio telegrams.

    USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE Telegram encryption The goal of telegram encryption is to prevent unauthorized receivers from correctly inter- preting the content of a telegram. In order to do so, the original (plain text) data is encrypted with a security key thus trans- forming it into encrypted, unreadable data.

  • Page 107: Replay Protection

    USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE Replay protection One fundamental problem with both telegram encryption and telegram authorization is that using the same input data (plain text) with the same security key will always result in the same encrypted data and the same signature.
  • Page 108 USER MANUAL TCM 515 / TCM 515U – ENOCEAN TRANSCEIVER GATEWAY MODULE TCM 515 uses an approach where the RLC is used to change the security material (specifi- cally, the initialization vector – often called Nonce - used by the security algorithms together with the security key) to ensure that the encrypted telegram payload and the telegram sig- nature change even when the content of the telegram itself stays the same.
