When TCM 615 receives a request from the host to transmit a telegram, it will transition to Transmit state and transmit the telegram as described in chapter 5. After that, it will auto- matically transition back to Receive state and continue to scan for EnOcean radio telegrams.

    TCM 615 supports the following filter types: Source EURID Filter ◼ The source EURID (EnOcean Universal Radio ID = EURID of the sender of the tele- gram) is evaluated. This filter type can for instance be used in actuators which only accept input from certain devices (e.g.

    For the case of selective repeating, filters with condition / action codes 0x00 and 0x40 will be ignored when evaluating the defined filters. TCM 615 support the definition of up to 30 individual filters in total. Attempting to define more than 30 filters will result in the response 01: RET_ERROR (memory space full).

    If the telegram payload of received telegrams is forwarded to the external host using the RADIO_ERP1 packet, then the structure shown in Table 10 below is used. For TCM 615 and TCM 615U, this is the packet format that is used by default. For TCM 615J, this packet format is not supported.

    4.3.3 RADIO_ERP2 packet format (TCM 615U and TCM 615J only) TCM 615U and TCM 615J use EnOcean Radio Protocol 2 (ERP2) for radio communication as described in [3]. Both devices can use RADIO_ERP2 packet to provide the telegram payload of received telegrams to the external host with the packet format shown in Table 11 below.

  • Page 33: Wait For Receive Maturity Time

    This provides the lowest latency and is the default operation mode for TCM 615. TCM 615 can be configured to wait for the receive telegram maturity time (100 ms) ◼ after reception of a subtelegram to determine the number of received subtelegrams.

  • Page 34: Transparent Mode

    Transparent mode In certain applications, all security protocol handling (secure teach-in, encryption, decryption and authentication) is executed by the external host and TCM 615 is used as simple trans- mitter / receiver only. TCM 615 can be configured to operate in transparent mode to disable all security processing functionality of TCM 615.

    TCM 615 / TCM 615U / TCM 615J – ENOCEAN TRANSCEIVER GATEWAY MODULE CRC length selection (TCM 615J devices only) EnOcean devices using ERP2 radio protocol use an 8-bit CRC value to ensure the integrity of the data payload within the radio telegram as described in Appendix A.2. For some legacy devices it has been observed that the last bit of the CRC is sensitive to disturbance and might sometimes not be correctly received.

RADIO_MESSAGE packets therefore allow using the same command for telegram transmis- sion on all TCM 615 products irrespective of the payload length and the radio protocol that is used.

    TCM 615 / TCM 615U / TCM 615J – ENOCEAN TRANSCEIVER GATEWAY MODULE Using Base ID for transmission As described in Appendix A.4.4, the use of Base ID allows TCM 615 modules to transmit messages using an ID different from its own EURID. Base ID is a legacy feature supported by TCM 615 for backwards compatibility and should not be used in new designs.

    If such signals are present in your design, we suggest separating them from the TCM 615 module as much as possible and to provide a ground plane between the TCM 615 module and such signal lines.

  • Page 82: Power Supply Requirements

    Suitable power supply design, layout and shielding is essential to optimize the radio perfor- mance of TCM 615. It is recommended to place a 22 µF ceramic capacitor between VDD and GND close to the module (material: X5R, X7R, min 6.3 V to avoid derating effects).

  • Page 83: Suggested Reset Circuit

    In order to avoid spurious reset events, it is recommended to filter the input signals by means of a small capacitor which is placed as close as possible to the TCM 615 nRESET pin as shown in Figure 23 below.

For the case of standard addressed telegrams, the maxi- mum length of the data payload is 9 bytes.

  • Page 118: Telegram Chaining

    The theoretical maximum DATA length within a chain of telegrams is 766 byte (63 * 12 byte + 1 * 10 byte). Note that in TCM 615 the maximum length is limited by the maximum size of an ESP3 command accepted by TCM 615 which is 255 byte.

  • Page 120: Telegram Chaining For Addressed Secure Telegram (Adt Sec_Cdm)

    The last SEC_CDM telegram might therefore be split into two addressed SEC_CDM telegrams due to the addition of the R-ORG and DESTINATION EURID addressing fields resulting in a telegram size larger than the maximum size of EnOcean radio telegrams.

    If different security keys are used for encryption at the sender and decryption at the receiver, then this is called an asymmetric key algorithm or a public key algorithm. Public / private key algorithms such as PGP, GPG or TLS fall into this category. TCM 615 does not support asymmetric key algorithms.
