2.2.1 Interface supply voltage - IOVDD
For digital communication with other circuitry (peripherals) the digital I/O configured pins
of the mixed signal sensor interface (ADIO0 to ADIO7) and the pins of the serial interface
(SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3) may be operated from supply voltages
different from DVDD. Therefore an interface voltage supply pin IOVDD is available which
can be connected either to DVDD or to an external supply within the tolerated voltage
range of IOVDD.
If DVDD=0 V (e.g. in any sleepmode) and IOVDD is supplied, there may be un-
predictable and varying current from IOVDD caused by internal floating nodes. It
must be taken care that the current into IOVDD does not exceed 10 mA while
DVDD=0.
If DVDD=0 V and IOVDD is not supplied, do not apply voltage to any above men-
tioned pin. This may lead to unpredictable malfunction of the device.
In TCM 320/TCM 320C VDD is internally connected to IOVDD! Therefore the above
mentioned issues have to be considered when writing own firmware based on API.
IOVDD voltage must not exceed VDD voltage! A malfunction of the module may be
caused by such inverse supply!
For I/O pins configured as analog pins the IOVDD voltage level is not relevant!

2.7 Repeater configuration
TCM 3x0 provides the option to activate a one or two-level repeater for EnOcean radio tele-
grams.
1-level repeater: If a received telegram is a valid and original (not yet repeated), the tele-
gram is repeated after a random delay.
2-level repeater: If a received telegram is valid and original or repeated once, the telegram
is repeated after a random delay.
The repeated telegram is marked as “repeated” by an increased repeater counter.
Setting the repeater level:
At start-up of the module repeater on/off and repeater level are determined.
Please refer to the table in 2.2 regarding the configuration options.
The figure below shows an example circuit for a repeater.
2-level repeating function should only be activated if really needed! Otherwise the
system function can be compromised by collisions of telegrams.
Please note that in Mode 0 2-level repeating is not possible
(for backward compatibility to TCM 220C)!

2.8 Teach-in procedure
Modes 1 to 4 support teach-in of transmitters.
2.8.1 Setting the receiver to learning mode
Via CLR Pin (ADIO4): Contact to GND longer than t = 2 seconds. Learning Mode LRN
is entered after clearing ID memory.
Via LRN Pin (ADIO3): Contact to GND longer than t = 0.5 seconds. In multi-channel
receiver mode, the pin has to be contacted several times until the desired channel num-
ber is selected (the number of channels is given by the selected operating mode).
Via Remote Config Control: Please refer to documentation of remote management.
2.8.2 Confirmation of Learning Mode
Mode Confirmation
0 No Learn capability
1 LMI HIGH continuously, LRN_TOGGLE toggling every 1 s.
2 LMI HIGH continuously, CHANNEL0 toggling every 1 s.
3 LMI HIGH continuously, current CHANNELx toggling every 1 s.
4 LMI HIGH continuously, DIM IND HIGH, and PWM toggling every 1 s between
10% and 100%
5 Reserved for future use
2.8.3 Teaching in a transmitter
In learning mode LRN, the sensitivity of the module is limited to in-room operations and
learning of repeater powered signals is disabled (to avoid unintentional learning). Therefore
ensure that the associated radio transmitter will be in a distance less than 5 m to the re-
ceiver (not necessary within Remote Learn Mode).
Trigger the telegram of the associated radio transmitter within 30 seconds:
Operate the switch radio transmitter (RPS or HRC) at least once (press I-button or O-
button of the rocker that is to be assigned to the selected receiver channel). If the same
rocker is operated again within 4 seconds it will still be learned. If the same rocker is op-
erated again after more than 4 seconds it will be deleted again. Please note that teach-in
without rocker information is not possible” Please note that scene switches (HRC and last
3 ID bits 0B111) cannot be teach-in!
Or activate the sensor radio transmitter (1BS, 4BS) least once with active LRN bit
(DI_3=0, please refer to “Standardization EnOcean Communication Profiles”). If the
same transmitter is operated again after more than 4 seconds with active LRN bit it will
be deleted again.
Please note that in modes 2, 3, and 4 only RPS or HRC telegrams can be learned!

2.8.4 Confirmation of correct learning/deletion
The output which is toggling every second while in teach-in mode (see above) will stay
switched high for 4 seconds to signal that a transmitter has been learned. In case a trans-
mitter ID has been deleted it will stay 4 seconds low.
2.8.5 Learning of further transmitters
After confirmation, the receiver changes again to readiness for learning. Further transmit-
ters can be learned immediately. If available the next receiver channel can be entered by
connecting the LRN pin to GND longer than t = 0.5 seconds. A maximum of 30 radio trans-
mitters can be learned (further attempts will be ignored; instead of learning confirmation,
operating mode is entered). Each rocker of a radio transmitter is counted as one transmit-
ter.
2.8.6 Selecting the next channel
By fresh contacting of the LRN pin to GND the next remaining channel is selected. In one-
channel mode or after the last channel, the operating mode is entered again.
2.8.7 Leaving learning mode
LRN mode is left in either one of the following events:
Output of last available channel is toggling and a fresh contacting of the LRN pin to GND
for 0.5 seconds is performed
No ID has been added/deleted during the last 30 seconds.
Memory was full and another ID was sent to be learnt
2.8.8 Deleting a transmitter
Deletion of one specific transmitter: Use the same procedure as learning the associated
transmitter.
As transmitter delete confirmation, the corresponding function outputs remain in inactive
state for 4 seconds while LMI keeps active. After that, a wrongly deleted transmitter can be
learned again immediately.
In order to delete a PTM transmitter the same rocker as during learn has to be
operated. If several rockers of a PTM transmitter have been learned, all have to be
deleted separately.
Deletion of all learned transmitters: Connect the CLR pin longer than 2 seconds to GND
All learned transmitters on all channels are deleted at the same time. After this, the re-
ceiver enters Learning Mode.

tem specification.
2.11 Transmit timing
The setup of the transmission timing allows avoiding possible collisions with data packages
of other EnOcean transmitters as well as disturbances from the environment. With each
transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmis-
sion of a subtelegram lasts approximately 1.2 ms. The delay between the three transmis-
sion bursts is affected at random.

3 APPLICATIONS INFORMATION
3.1 Transmission range
The main factors that influence the system transmission range are type and location of the
antennas of the receiver and the transmitter, type of terrain and degree of obstruction of
the link path, sources of interference affecting the receiver, and “dead” spots caused by
signal reflections from nearby conductive objects. Since the expected transmission range
strongly depends on this system conditions, range tests should categorically be performed
before notification of a particular range that will be attainable by a certain application.
The following figures for expected transmission range are considered by using a PTM, a
STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled
whip antenna and may be used as a rough guide only:
Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls
Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls
Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls
Ferro concrete walls / ceilings: Typically 10 m range, through max. 1 ceiling
Fire-safety walls, elevator shafts, staircases and supply areas should be considered as
screening.
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:
Switch mounted 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 EnOcean receivers and other transmitting devices such as com-
puters, audio and video equipment that also emit high-frequency signals should be at least
0.5 m
A summarized application note to determine the transmission range within buildings is
available as download from www.enocean.com.

3.3 Antenna options TCM 320 / 320C
Positioning and choice of receiver and transmitter antennas are the most important factors
in determining system transmission range.
3.3.1 Mounting the whip antenna
For good receiver performance, great care must be taken about the space immediately
around the antenna since this has a strong influence on screening and detuning the an-
tenna. The antenna should be drawn out as far as possible and must never be cut off.
Mainly the far end of the wire should be mounted as far away as possible (at least 15 mm)
from all metal parts, ground planes, PCB strip lines and fast logic components (e.g. micro-
processors).
Do not roll up or twist the whip antenna!
Radio frequency hash from the motherboard desensitizes the receiver. Therefore:
PCB strip lines on the user board should be designed as short as possible
A PCB ground plane layer with sufficient ground vias is strongly recommended
See also section 3.5 for power supply requirements. Problems may especially occur with
switching power supplies!

Isolation material may brake at temperatures below -15 °C.
Please take care to fix the antenna cable in case vibrations are expected.
3.3.2 Mounting 50 Ω antennas
For mounting the receiver at bad RF locations (e.g. within a metal cabinet), an external 50
Ω antenna may be connected. The whip antenna must be removed in this case!
TCM 320 / 320C provide soldering pads for an SMA connector, e.g. from Tyco Electronics:
Modification procedure:
TCM320: Remove whip antenna and mount SMA connector
TCM320C: Remove whip antenna and 12pF capacitor. Then mount SMA connector
For 315 MHz modules (TCM 300C and TCM 320C) please note that a full approval
is needed if modules are used with external antennas.
When using the SMA connector pads please make sure no mechanical forces are
exerted on the 16-pin connector! It is recommended to use a strain relief for that
purpose.

3.5 Power supply requirements
In order to provide a good radio performance, great attention must be paid to the power
supply and a correct layout and shielding. It is recommended to place a 22 µF ceramic ca-
pacitor between VDD and GND close to the module (material: X5R, X7R, min 6.3 V to avoid
derating effects). In addition a 470 nH coil shall be inserted (Murata LQW18A, 0603) in the
power supply line.
It is recommended to keep the ripple on the power supply rail below 10 mVpp (see 2.4).

TCM 300 has to be soldered according to IPC/JEDEC J-STD-020C standard.
TCM 300 shall be handled according to Moisture Sensitivity Level MSL4 which means a floor
time of 72 h. TCM 300 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 72 h, they may be baked according IPC/JEDEC J-STD-033B.
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 300 modules have to be soldered within 6 months after delivery!

A APPENDIX
A.1 EnOcean serial protocol
When the receiver is in “Serial Interface” mode, it transfers out data blocks of information
from the received RF telegrams. As long as no transmitter has been learned, all received
EnOcean telegrams are transferred. As soon as at least one transmitter has been learned
only telegrams of transmitters learned by the receiver are transmitted via the serial inter-
face. The data block format is explained later in this document; it depends on the type of
sensor from which the telegram has been received.
A.1.1 Message format
The following figure shows the message format. A block is composed of 2 synchronization
bytes, 1 byte for the header and N bytes for the message data.
Message format for asynchronous serial communication
A.1.2 Byte signals and bit order
9600 bps; 8 data bits, no parity bit, one start bit, one stop bit

IMPORTANT NOTE FOR SYSTEMS USING AN ENOCEAN RADIO REPEATER:
Within toggle switch applications using the serial receiver mode in combination
with a separate repeater, please ensure that no serial command interpretation
error may occur at the connected control unit. A toggle signal means that the
same telegram is sent for switching something on and off. If e.g. the light is
switched on receiving the I-button telegram from a PTM 200C, the repeated tele-

interpret the RP_COUNTER field. If a repeated telegram (RP_COUNTER>0) is re-
ceived it has to be verified if the same telegram with a lower RP_COUNTER state
has already been received in the previous 100 ms. In this case the repeated mes-
sage has to be discarded.
PTM switch modules of Type 2 (e.g. PTM 200) allow interpretation of operating two buttons
simultaneously:
N-message received Æ Only one or two pushbuttons have been pressed.
U-message received Æ No pushbutton was pressed when activating the energy genera-
tor, or more than two pushbuttons have been pressed.
Note for telegrams from PTM transmitters: Due to the mechanical hysteresis of the energy
bow, in most rocker switch device implementations, pressing the rocker sends an N-
message and releasing the rocker sends a U-message!

A.3 Command telegrams and messages
A.3.1 ID Range commands
Every TCM 300 supports a unique 32 bit ID and in addition a range of 128 IDs starting at
an BaseID address. At production, every TCM 300 is programmed with a unique ID and a
BaseID address. The BaseID number can be read via the serial interface. In order to allow a
replacement of one unit with another unit (without having to go through the learning pro-
cedure with every receiver), the ID range can be changed via the serial interface.
The allowed ID range is from 0xFF800000 to 0xFFFFFFFF.
In order to prevent misuse, this feature can only be used 10 times!
Please note: The unique ID cannot be changed.
Command (TCT) Response (RMT)
SET_BASEID OK, ERR, ERR_IDRANGE
RD_BASEID INF_BASEID
A.3.2 Receiver sensitivity commands
The receiver sensitivity can be changed by the following commands. In LOW sensitivity
mode, only transmitters in the vicinity of the module are received.

A.3.6 Command Encoding
OK
Bit 7 Bit 0
Standard message used to confirm that an action was performed
correctly by the TCM.
In case of full duplex communication it may happen that serial
telegrams get corrupted and lost. Therefore it is recommended to
check for “OK” where applicable.
ERR
Bit 7 Bit 0
Standard error message response if after a TCT command the
operation could not be carried out successfully by the TCM.
SET_BASEID
Bit 7 Bit 0
With this command the user can rewrite its ID range base num-
ber. The most significant ID byte is BaseIDByte3. The informa-
tion of the 25 most significant bits is stored in FLASH.
The allowed ID range is from 0xFF800000 to 0xFFFFFFFF.
32 0
BaseID
This command can only be used a maximum number of 10 times.
After successfully ID range reprogramming, the TCM answers
with an OK telegram. If reprogramming was not successful, the
TCM answers sending an ERR telegram if the maximum number
of 10 times is exceeded or an ERR_IDRANGE telegram if the
BaseID is not within the allowed range.

Bit 7 Bit 0
When this command is sent to the TCM, the base ID range num-
ber is retrieved though an INF_BASEID telegram.
INF_BASEID
Bit 7 Bit 0
This message informs the user about the ID range base number.
BaseIDByte3 is the most significant byte.
SET_RX_SENSITIVITY
Bit 7 Bit 0
This command is used to set the TCM radio sensitivity.
