TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver
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 transparent 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.

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 ANTENNA input (Pin 2).
TCM 515Z communicates with the external host using the standard ESP3 serial (UART) interface 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 interface.
The forwarded frame starts with the Length field of the IEEE 802.15.4 PHY Header, continues 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 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).

Supported Radio Channels
TCM 515Z support all radio channels of the IEEE 802.15.4 standard in the 2.4 GHz band.
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.

Device handling instructions
TCM 515Z shall be handled according to Moisture Sensitivity Level MSL 3. 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.

APPLICATION INFORMATION
5.1
Transmission range
The main factors that influence the system transmission range are:
- Type and location of the antennas of receiver and transmitter
- Type of terrain and degree of obstruction of the link path
- Sources of interference affecting the receiver
- “Dead spots” caused by signal reflections from nearby conductive objects.
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.

Appendix A
IEEE 802.15.4 Frame Structure
A.1 IEEE 802.15.4 High Level Frame Structure
TCM 515Z transmits and receives radio telegrams in the 2.4 GHz band according to IEEE
802.15.4 frame structure. The external host is responsible for the proper decoding of received 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 information 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 telegram security (if present) fields.
The MAC Payload field structure depends on telegram type (data or commissioning)
and security mode (secure or standard transmission).

MAC Trailer
The MAC Trailer contains the Frame Check Sum (FCS) field used to verify the integrity of the telegram data.
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 supported 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)

A.3 MAC Header
The IEEE 802.15.4 MAC Header contains the following fields:

Frame Control Field (2 byte)
The Frame Control Field is set to 0x0801 in PTM 215ZE and PTM 535Z telegrams in
order to identify them as data telegrams with short addresses based on version IEEE
802.15.4-2003

Sequence Number (1 byte)
The Sequence Number is an incremental number used to identify the order of telegrams

Address Field (4 byte in EnOcean implementation)
EnOcean devices use short Destination Address (16 Bit) together with the Destination PAN ID (16 Bit). 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 below shows the MAC Payload structure of a secure data telegram with authentication used by PTM 215ZE or PTM 535Z.
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 signature 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 inputs 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 telegram 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 telegram validation for PTM 215ZE or PTM 535Z data telegrams.

secure mode with authentication and additional payload encryption (optional feature).

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 provided. 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.

ESP3 Interface Format
Packet Type 0x10: IEEE 802.15.4 Raw Packet
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 interface.
The forwarded frame starts with the Length field of the IEEE 802.15.4 PHY Header, continues 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 payload 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).

RESPONSE for IEEE 802.15.4 Raw Packets
When receiving a telegram, no RESPONSE has to be sent from the external host to the
gateway to acknowledge reception of the telegram via ESP3 interface.
When transmitting a telegram, the gateway will send a RESPOND message to the external
host via ESP3 interface to indicate the acceptance of the telegram for transmission. The
following return codes are applicable for such a RESPONSE message:



00 RET_OK
02 RET_NOT_SUPPORTED
03 RET_WRONG_PARAM
The structure of the gateway RESPONSE message to the request for transmission of an
IEEE 802.15.4 Raw Packet is shown in Table 9 below. TCM 515Z will transmit a dedicated
message to a connected host if transmission of an accepted telegram subsequently fails.
