USER MANUAL TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver © 2016 EnOcean | www.enocean.com F-710-017, V1.0 TCM 515Z User Manual | v1.5 | June 2017 | Page 5/45 1 GENERAL DESCRIPTION 1.1 Basic functionality TCM 515Z enables the realization of line-powered actuators, controllers and gateways communicating based on the 2.4 GHz IEEE 802.15.4 radio standard. It provides a transpar-ent radio link between EnOcean 2.4 GHz devices and an external host connected via the standardized ESP3 interface (EnOcean Serial Protocol, version 3). TCM 515Z receives and transmits radio telegrams based on a 50 Ohm or whip antenna connected to the host PCB. It forwards received 2.4 GHz IEEE 802.15.4 radio telegrams to an external host processor or host PC via the ESP3 interface. IEEE 802.15.4 messages received from an external host via the ESP3 interface will be transmitted by TCM 515Z as 2.4 GHz radio telegrams. TCM 515Z is implemented as 31 pin reflow-solderable module with optimized form factor for size constrained applications. Figure 1 below shows TCM 515Z. Figure 1 – TCM 515Z outline

USER MANUAL TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver © 2016 EnOcean | www.enocean.com F-710-017, V1.0 TCM 515Z User Manual | v1.5 | June 2017 | Page 8/45 2.1.1 Signal Description TCM 515Z is supplied by the VDD and GND Pins. The required supply voltage is 3.3V with a tolerance of no more than +-10%. TCM 515Z receives and transmits data based on a 50Ω whip antenna connected to its AN-TENNA input (Pin 2). TCM 515Z communicates with the external host using the standard ESP3 serial (UART) in-terface based on the signals UART_TX (Pin 21, direction from TCM 515Z to external host) and UART_RX (Pin 20, direction from external host to TCM 51Z). The default interface speed of the ESP3 interface is 57600 bit per second (the exact speed is 57347 Bit per second, a deviation of -0.04%). It is possible to select faster communication speeds of 115200, 230400 and 460800 bit per second during operation using the CO_SET_BAUDRATE command as shown in Table 16. Additionally it is possible to change the default ESP3 interface speed at power up from 57.600 Bit per second to 460.800 Bit per second by connecting the TURBO input (Pin 31) to Ground. Subsequent modification of the interface speed during operation using the CO_SET_BAUDRATE command is always possible irrespective of the state of the TURBO input pin. 2.2 High-level operation principle In receive mode, TCM 515Z forwards the content of received IEEE 802.15.4 radio telegrams (which pass frame check sum validation) unmodified to the external host via the ESP3 in-terface. The forwarded frame starts with the Length field of the IEEE 802.15.4 PHY Header, contin-ues with the MAC Header and ends with the last Byte of the MAC Payload. The frame check sum (MAC Trailer) will not be forwarded to the host. In transmit mode, TCM 515Z receives from the external host the precomputed message payload starting with the Length field of the IEEE 802.15.4 PHY Header, continuing with the MAC Header and ending with the last Byte of the MAC Payload. TCM 515Z then calculates the frame check sum (MAC Trailer) and appends it to the mes-sage. The full frame (including the Preamble and Start of Frame fields) will then be trans-mitted as IEEE 802.15.4 radio telegram (TX mode).

The radio channel used by TCM 515Z can be set by an external host using the ESP3 SET_CHANNEL command as described in Appendix C.2.3. The channel notation used by TCM 515Z follows IEEE 802.15.4 standard, i.e. channel 11 is the first channel (lowest frequency) and channel 26 is the last channel (highest frequency). Table 2 below shows the correspondence between channel ID and channel frequency. Table 2 - Supported radio channels

The default baud rate of this interface is 57600 bps. If the TURBO pin is set to active low then the baud rate is increased to 460.800 bps. 2.4.1 ESP3 Data Format TCM 515Z communicate with external hosts using EnOcean Serial Protocol version 3 (ESP3) with EnOcean 2.4 GHz IEEE 802.15.4 extensions.

TCM 515Z may be soldered only once, since one time is already consumed at production of the module itself. Once the dry pack bag is opened, the desired quantity of units should be removed and the bag resealed within two hours. If the bag is left open longer than 30 minutes the desiccant should be replaced with dry desiccant. If devices have exceeded the specified floor life time of 168 h, they may be baked according IPC/JEDEC J-STD-033B at max. 90 °C for less than 60 hours. Devices packaged in moisture-proof packaging should be stored in ambient conditions not exceeding temperatures of 40 °C or humidity levels of 90% r.H. TCM 515Z modules have to be soldered within 6 months after delivery! In general we recommend a no clean flux process. If washing is needed, then TCM 515Z radio modules have a shield cover with small openings at the top of the edges. It is very important to mount the modules in a top down position during the drying process as this will allow getting the aggregated washing fluid removed properly from within the shield cover area. To prevent damage, modules have to be checked for any remaining fluid after the drying.

Since the expected transmission range strongly depends on this system conditions, range tests should always be performed to determine the reliably achievable range under the given conditions. The following figures should be treated as a rough guide only: - Line-of-sight connections Typically 15 m range in corridors, up to 50 m in halls - Plasterboard walls / dry wood Typically 15 m range, through max. 2 walls - Ferro concrete walls / ceilings Maximum 1 wall or ceiling, depending on thickness and material - Fire-safety walls, elevator shafts, staircases and similar areas should be considered as shielded The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoided. Other factors restricting transmission range include: - Switch mounting on metal surfaces (up to 30% loss of transmission range) - Hollow lightweight walls filled with insulating wool on metal foil - False ceilings with panels of metal or carbon fibre - Lead glass or glass with metal coating, steel furniture The distance between the receiver and other transmitting devices such as computers, audio and video equipment that also emit high-frequency signals should be at least 0.5 m.

The external host is responsible for the proper decoding of re-ceived telegrams and proper encoding of telegrams to be transmitted. The following information about the IEEE 802.15.4 standard and its implementation in PTM 215ZE and PTM 515Z is given for reference only. Please refer to the applicable documents for detailed information. Note that the data format is little endian. This means that for multi-byte structures (such as 2 byte, 4 byte or 8 byte fields) the least significant byte (LSB) is transmitted first. The IEEE 802.15.4 frame structure consists of the following four main parts:  PHY Header The PHY header indicates to the receiver the start of a transmission and provides in-formation about the length of the transmission. It contains the following fields: o Preamble Pre-defined sequence (4 byte, value 0x00000000) used to adjust the receiver to the transmission of the sender o Start of frame Pre-defined symbol (1 byte, value 0xA7) identifying the start of the actual data frame o Length of Frame 1 byte indicating the combined length of all following fields  MAC Header The MAC header provides detailed information about the frame. It contains the following fields: o Frame control field 2 bytes to identify frame type, protocol version, addressing and security mode o Sequence number 1 byte sequential number to identify the order of transmitted frames o Address PAN ID and address of source (if present) and destination of the telegram EnOcean PTM 535Z and PTM 215ZE do not use source address and source PAN ID (the EnOcean ID is part of the payload).  MAC Payload The MAC Payload field contains telegram control, device ID, telegram data and tele-gram security (if present) fields. The MAC Payload field structure depends on telegram type (data or commissioning) and security mode (secure or standard transmission).

Figure 16 below summarizes the IEEE 802.15.4 frame structure. Figure 16: IEEE 802.15.4 frame structure The content of these fields is described in more detail below. A.2 PHY Header The IEEE 802.15.4 PHY header consists of the following fields:  Preamble  Start of Frame  Length of Frame fields The content of the Preamble and Start of Frame fields is fixed for all telegram types sup-ported by EnOcean devices as follows:  Preamble = 0x00000000  Start of Frame = 0xA7 A.2.1 Length of Frame values used by PTM 215ZE and PTM 535Z Below are reference values for the Length of Frame field for different type of telegrams used by PTM 215ZE and PTM 535Z:  Secure commissioning telegram (Default for PTM 215ZE and PTM 535Z) Length of Frame = 42 bytes (0x2A)  Secure data telegram (Default for PTM 215ZE and PTM 535Z) Length of Frame = 24 bytes (0x18)  Standard commissioning telegram (Optional feature for PTM 535Z only) Length of Frame = 17 bytes (0x11)  PTM switch: Standard data telegram (Optional feature for PTM 535Z only) Length of Frame = 15 bytes (0x0F)

Both are set to 0xFFFF to identify the telegrams as broadcast. Source address and Source PAN ID are not used by PTM 215ZE and PTM 535Z. A.4 MAC Payload The IEEE 802.15.4 MAC Payload depends on the telegram type. Appendix B describes the MAC Payload structure used by EnOcean PTM 215ZE and PTM 535Z products. A.5 MAC Trailer The MAC Trailer only contains the Frame Check Sum (FCS) field. Its length is 2 byte and it is calculated as Cyclic Redundancy Check (CRC16) over the entire MAC payload including the Length field of the PHY Header using the following polynomial: x16 + x12 + x5 + 1 TCM 515Z will automatically calculate and append the frame check sum to radio telegrams it is transmitting. For received radio telegrams, TCM 515Z will calculate the frame check sum and verify data integrity based on that. If the checksum does not match, the received radio telegram will be discarded. Otherwise the received radio telegram will be forwarded to the external host via the ESP3 interface.

Figure 17: MAC Payload structure for authenticated data telegrams The following fields are used:  Telegram Control (2 bytes) The default security mode of PTM 215ZE and PTM 535Z uses a 4 byte payload signa-ture based on a device-unique key and a 4 byte Sequence Counter. The Telegram Control field is set to 0x308C for this mode.  Source ID (4 bytes) The Source ID field contains a 4 byte ID uniquely identifying each PTM 215ZE or PTM 535Z device  Sequence Counter (4 bytes) The Sequence Counter field contains an always incrementing counter. Security processing is based on the combination of the Command and Sequence Counter in order to prevent replay attacks (sending the same telegram again)  Command (1 byte) The Command field is a one byte field which identifies the state of the different in-puts of PTM 215ZE or PTM 535Z. For the encoding please see the applicable data manual.  Telegram Signature (4 byte) The Telegram Signature field is used to validate the telegram authenticity. The tele-gram signature is calculated based on the telegram payload using AES128 (CBC mode). In this mode, telegrams contain both a 4 byte sequence counter and a 4 byte signature which is calculated based on the telegrams payload (including the sequence counter) and the private key. The implementation is specified in RFC3610 and compatible with ZigBee systems. EnOcean can provide upon request additional information on how to implement tele-gram validation for PTM 215ZE or PTM 535Z data telegrams.

The Device Options field is set to 0xF381 by PTM 535Z when operating in AES128 secure mode with authentication and additional payload encryption (optional fea-ture).  Device-unique Security Key (16 bytes) PTM 215ZE and PTM 535Z implement a random, device-specific security key which is generated as part of the production flow. During commissioning, this key is transmitted in encrypted format. Contact EnOcean for details.  Security Key Validation (4 bytes) In order to ensure correct reception, an additional 4 byte validation value is pro-vided. Contact EnOcean for details.  Sequence Counter (4 bytes) The Sequence Counter is an always incrementing counter which is used as part of the security processing to avoid replay attacks (sending the same telegram again).  Receiving devices shall only accept data telegrams with sequence counter values higher than that of the last received telegram; therefore the current value needs to be communicated during commissioning.

The forwarded frame starts with the Length field of the IEEE 802.15.4 PHY Header, contin-ues with the MAC Header and ends with the last Byte of the MAC Payload. The frame check sum (MAC Trailer) will not be forwarded to the host. In transmit mode, TCM 515Z receives from the external host the precomputed message payload starting with the Length field of the IEEE 802.15.4 PHY Header, continuing with the MAC Header and ending with the last Byte of the MAC Payload. TCM 515Z then calculates the frame check sum (MAC Trailer) based on the received pay-load and appends it to the message. The full frame (including the Preamble and Start of Frame fields) will then be transmitted as IEEE 802.15.4 radio telegram (TX mode).
