2.2.1 GPIO 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 varyin
g
current from IOVDD caused by internal floatin
g
nodes. It
must be taken care that the current into IOVDD does not exceed 10 mA while
DVDD=0 V.
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!
However it is important to connect IOVDD to a supply voltage as specified in 2.4.

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 make sure not to remove supply voltage while in LRN mode! The flash con-
tent could get corrupted!

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
transmitters can be learned (further attempts will be ignored; instead of learning confirma-
tion, operating mode is entered). Each rocker of a radio transmitter is counted as one
transmitter.
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 durin
g
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.
Please note that in modes 2, 3, and 4 only RPS or HRC telegrams can be learned!

2.10 Smart Acknowledge
TCM 3x0 provides a post master function with 15 mail boxes for systems using EnOcean
smart acknowledge technology. This functionality is switched on in all operating modes.
For detailed information on smart acknowledge please refer to the Smart Acknowledge sys-
tem specification.
When teachin

Smart Acknowled
g
e please take care to switch off
all TCM 3xy devices which are not continuously powered. Otherwise these TCM 3xy
modules could be declared postmaster. As soon as the power supply is switched
off a postmaster would be missing and Smart Acknowledge would not work any
longer!
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.

3APPLICATIONS 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.
