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. The transmission of a sub­telegram lasts approximately 1.2 ms. To optimize data security, each telegram is repeated
twice within about 40 ms, whereas the delay between the three transmission bursts is ef­fected 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 30m range in corridors, up to 100m in halls
 Plasterboard walls / dry wood: Typically 30m range, through max. 5 walls
 Line-of-sight connections: Typically 30m range in corridors, up to 100m in halls
 Ferroconcrete walls / ceilings: Typically 10m 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 fiber
 Lead glass or glass with metal coating, steel furniture

The distance between EnOcean receivers and other transmitting devices such as comput­ers, audio and video equipment that also emit high-frequency signals should be at least

0.5m

TCM200C / 220C

3.2 Mounting the antenna

Positioning and choice of receiver and transmitter antennas are the most important factors
in determining system transmission range.

TCM200C and TCM220C are providing two antenna outputs, ANT1 and ANT2:

 ANT1 is designed for use with a 15cm whip antenna
 ANT2 is designed for use with 50Ω antennas, e.g. helix antenna or external antenna

3.2.1 Mounting the 15cm 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 anten­na. 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. microproces­sors).
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 3.3 for power supply requirements. Problems may especially occur with

switching power supplies!

TCM200C / 220C

3.2.2 Mounting 50Ω antennas

For mounting the receiver at bad RF locations (e.g. within a metal cabinet), an external
antenna has to be used.

 Unsolder the whip antenna (if already mounted)
 Connect external antenna to the module by 50Ω coax cable with Teflon insulation

  Connect the inner cable to the ANT2 antenna hole on the PCB
  Solder the shielding as short as possible to the antenna GND pad

(length of insulation max. 4 mm)

It is also possible to mount other 50Ω antennas – such as off the shelf helix antennas –
onto the module. In this case the GND pad is not used.

3.3 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. A star-connected topology and at least a 22uF
low-ESR tantalum or similar ceramic capacitor is recommended. This capacitor must be
located as close as possible to the module, between the module supply pin VCC and GND.
Furthermore, a low DC-resistance (<1Ω) EMI-suppressor is needed in series between the
board supply pin input and the output of the power supply rail. We recommend a ferrit
bead e.g. multi layer suppressor type MLS0805-4S7-102 from Ferroxcube.

The ripple on the power supply rail must be below 10 mVpp.

3.4 Connecting Open Collector or Open Drain Outputs

The term open-collector typically refers to a transistor output where the collector output
(collector for bipolar transistors, drain for MOSFETs) of the transistor is not yet connected
to a positive voltage internally. Since a transistor used in an output is typically a saturated
switch, the collector needs to be connected to a positive voltage to complete the circuit.
This positive voltage does not need to be any specific value as long as it is above the tran­sistor saturation level. Therefore, an open collector/drain output offers more flexibility and
can be connected to a broad range of voltages using an adequate pull-up/load resistor. This
resistor is required for the output as it completes the transistor's circuit.

Applications of open-collector/drain devices:

One useful property is that the resistor does not need to be connected to the same supply
voltage: a lower or higher voltage can be used instead. Open collector/drain circuits are
therefore sometimes used to interface two devices that have different operating logic levels
(voltages) or even to directly drive higher voltage external loads (e.g. relays).

Another advantage is that more than one open-collector/drain output can be attached to a
single wire. If all outputs attached to the wire are in the high-impedance/logic 1 state, the
pull-up resistor will hold the wire in a high voltage state. If at least one of the device
outputs is in the ground/logic 0 state, it will sink current and bring the line voltage low.

3.5 Transmission range

The main factors that influence the system transmission range are:

o Type and location of the antennas of receiver and transmitter
o Type of terrain and degree of obstruction of the link path
o Sources of interference affecting the receiver
o “Dead” spots caused by signal reflections from nearby conductive objects

Since the expected transmission range strongly depends on these system conditions, range
tests should categorically be performed in early project phases!

The following figures for expected transmission range are considered by using a PTM, or
STM transmitter device and the TCM radio transceiver device with preinstalled whip anten­na and may be used as a rough guide only:

o Line-of-sight connections: Typically 30m range in corridors, up to 100m in halls
o Plasterboard walls / dry wood: Typically 30m range, through max. 5 walls
o Brick walls / aerated concrete: Typically 20m range, through max. 3 walls
o Ferroconcrete walls / ceilings: Typically 10m range, through max. 1 ceiling
o 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:

o Switch mounted on metal surfaces (up to 60% loss of transmission range)
o Hollow lightweight walls filled with insulating wool on metal foil
o False ceilings with panels of metal or carbon fiber
o Lead glass or glass with metal coating, steel furniture

battery. The module transmits short radio packets comprised of control signals, (in some
cases the control signal may be accompanied with data) such as those used with alarm sys­tems, door openers, remote switches, and the like. The module does not support conti­nuous streaming of voice, video, or any other forms of streaming data; it sends only short
packets containing control signals and possibly data. The module is designed to comply
with, has been tested according to 15.231(a-c), and has been found to comply with each
requirement. Thus, a finished device containing the TCM200C/TCM220C radio module can
be operated in the United States without additional Part 15 FCC approval (approval(s) for
unintentional radiators may be required for the OEM’s finished product), under EnOcean’s
FCC ID number. This greatly simplifies and shortens the design cycle and development
costs for OEM integrators. The module can be triggered manually or automatically, which
cases are described below.

Manual Activation

The radio module can be configured to transmit a short packetized control signal if trig­gered manually. The module can be triggered, by pressing a switch, for example.
The packet contains one (or more) control signals that is(are) intended to control some­thing at the receiving end. The packet may also contain data. Depending on how much
energy is available from the energy source, subsequent manual triggers can initiate the
transmission of additional control signals. This may be necessary if prior packet(s)
was(were) lost to fading or interference. Subsequent triggers can also be initiated as a pre­caution if any doubt exists that the first packet didn’t arrive at the receiver. Each packet
that is transmitted, regardless of whether it was the first one or a subsequent one, will only
be transmitted if enough energy is available from the energy source.

Automatic Activation

The radio module also can be configured to transmit a short packetized control signal
if triggered automatically, by a relevant change of its inputs or in response to receiving a
signal from another transmitter, for example. Again, the packet contains a control signal
that is intended to control something at the receiving end and may also contain data. As
above, it is possible for the packet to get lost and never reach the receiver. However, if
enough energy is available from the energy source, and the module has been configured to
do so, then another packet or packets containing the control signal may be transmitted at a
later time.

The device is designed to operate as a repeater, which can receive signals from the follow­ing list of FCC/IC approved transmitters, and retransmit the signals.

NU (1 bit) NU=1 Æ N-message, NU=0 Æ U-message.
RP_COUNTER (4 bit) =0..15 Repeater level: 0 is original message (not repeated)

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 tele­gram (delay <100ms) may switch off the light again. It is therefore mandatory to
interpret the RP_COUNTER field. If a repeated telegram (RP_COUNTER>0) is re­ceived 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 mes­sage has to be discarded.

PTM switch modules of Type 2 (e.g. PTM 200C)

allow interpretation of operating two but-

tons 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 N­message and releasing the rocker sends a U-message!

If ORG = 6, 7 or 8 (all other tele grams):

7 0

Reserved RP_COUNTER

Reserved (4 bit) For future use
RP_COUNTER (4 bit) Repeater level: 0 is original message (not repeated)
