1. GENERAL DESCRIPTION

The receiver module RCM 152 is used to receive and to process telegrams generated and
transmitted by EnOcean radio transmitters. These modules can be easily integrated into
control and switching units for the implementation of different application-specific system
solutions.

1.1 Basic Functionalities

For the implementation of different application-specific system solutions the RCM radio
modules can be easily integrated into control and switching units by using the functional
control outputs (“open collector”).

The RCM 152 is a firmware variant of the RCM 1xx receiver family of EnOcean. The hardware
is fully compatible.

Each RCM 152 receiver can be assigned, either a maximum of 30 EnOcean PTM radio switches,
or up to 2 EnOcean easyfit STM 250 radio window contacts. Learning of mixed PTM and STM
transmitters is not possible. By assigning the first transmitter the operating mode is defined.
The operating mode can only be changed at empty ID memory, e.g. after deleting all
transmitters with the CLR button.

Mode RADIO SWITCH: Each assigned transmitter can be used to change the switching state
of the receiver. It is possible to switch ON with one switch and OFF with another switch.

Mode RADIO WINDOW CONTACT: If at least one of the assigned window contacts is open
the switching state of the receiver is ON. If both contacts are closed the state is OFF. The radio
window contacts are transmitting a life signal typically every 15 min. Around 60 min after
reception of the last life signal the receiver considers this contact to be closed.

2.3.2 Firmware enabled Operating Modes

Each RCM 152 receiver can be assigned, either a maximum of 30 EnOcean PTM radio switches,
or up to 2 EnOcean easyfit STM 250 radio window contacts. Learning of mixed PTM and STM
transmitters is not possible. By assigning the first transmitter the Firmware Operating Mode is
defined. The Firmware Operating Mode can only be changed at empty ID memory, e.g. after
deleting all transmitters with the CLR button.

a) Mode RADIO SWITCH: Each assigned transmitter can be used to change the switching
state of the receiver. It is possible to switch ON (button I) with one switch and OFF (button O)
with another switch.

Initialization: After Power-up and Learning Phase the module output OUT_0 is
inactive (“off”). At least one of the learned radio switches have to be operated to switch
the output.

b) Mode RADIO WINDOW CONTACT: If at least one of the assigned window contacts is
open the switching state of the receiver is ON. If both contacts are closed the state is OFF.

Time Out: The radio window contacts are transmitting a life signal typically every 15
min (5…30 min). 60 min (± 10%) after reception of the last life signal the receiver
considers this contact to be closed.
Initialization: After Power-up and Learning Phase the module output OUT_0 is
inactive (“off”). At least one of the learned magnet contacts have to be opened to
release the output immediately (before first incoming presence signal).

RCM 152 User Manual V1.31

2.4 Learning Modes

The following learning modes are implemented within the RCM 152 module:

1.) Learning Mode CLR: ID Memory Reset. All learned transmitter IDs are deleted.
Learning mode LRN is entered subsequently. CLR mode has to be entered also for
changing the receiver operating mode (changed connections pattern at pins CODE_2..0
is taken over).

2.) Learning Mode LRN: Transmitter Learning Mode entered via LRN pin: The receiver
sensitivity is limited to in-room operation, learning of repeater-powered signals is
disabled. The telegram of the associated radio transmitter has to be triggered one time
at least (pressing the desired switch rocker or triggering a sensor).

3.) Learning Mode RLM: Not available with RCM 152.

4.) Learning Mode SSLM: Not available with RCM 152.

Indistinct signal or pin configurations are ignored at all times. Within the learning procedure,
the learning mode cannot be changed.

2.5 Learning of Radio Transmitters

Please also draw attention to the notes about learnable transmitters in chapter 2.2 “Operating
Modes”. LMI pin is active high during all learning modes.

1.) Setting the receiver to learning mode

- Via CLR Pin: Contact to GND longer than t = 2 sec. Learning Mode LRN is entered
after clearing transmitter-ID memory.

- Via LRN Pin: Contact to GND longer than t = 0.5 sec. In multi-channel receiver
modes, the pin has to be contacted several times until the desired channel number is
selected (the number of channels is given by the selected operating mode =
Code_2..0 pin configuration).

- Via Configuration Remote Control: Not possible with RCM 152.

- Via SSLM Pin: Not available with RCM 152.

2.) The receiver will confirm Learning Mode (i.e. via LEDs in parallel to the
output pins)

Output of the selected channel is flashing (1 sec. active / 1 sec. inactive)

3.) Ensure that the associated radio transmitter will be in a distance less
than 5 m to the receiver

In learning mode, the sensitivity of the RCM module is limited to in-room operations
and learning of repeater powered signals is disabled (to avoid unintentional learning).

©EnOcean GmbH

Page 11 of 20

RCM 152 User Manual V1.31

5.) Trigger the telegram of the associated radio transmitter within 30 sec. at
the latest

- Operate the PTM switch radio transmitter at least once (press I-button or O-button of

the rocker that is to be assigned to the selected receiver channel).

- Or press the LEARN button of the STM 250 magnet contact transmitter at least once.

- Through fresh contacting of the LRN pin to GND, Operation Mode is entered again (no

output is flashing any more and LMI output changes to inactive).

- After approx. 30 seconds of inactivity (no transmitter has been triggered), the

receiver switches back from Learning Mode to Operating Mode automatically.

6.) The receiver will confirm the correct learning of transmitter ID code

The output of the selected channel remains in active state for 4 sec.

7.) Learning of further transmitters

After confirmation, the receiver changes again to readiness for learning. Further transmitters
can be learned immediately. A maximum of 30 PTM transmitters or 2 STM 250 transmitters
can be learned (further attempts will be ignored; instead of learning confirmation, Operation
Mode is entered).

8.) Leave the learning mode

Contact again the LRN pin to GND longer than t = 0.5 sec.

Note: After passing the Learning Mode the OUT_0 open collector output is inactive
and, if STM 250 are learned, the Time Out Timer is reset.

2.6 Deleting Radio Transmitters

a) 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 sec. while LMI keeps active. After that, a wrongly deleted
transmitter can be learned again immediately.

b) Deletion of all learned transmitters: Connect the CLR pin longer than 2 sec. to

GND

All learned transmitters on all channels are deleted at the same time. After this, the
receiver enters Learning Mode LRN.

2.7 Received Signal Strength Indicator (RSSI)

The RSSI output of the RCM module is useful for transmission range tests. By indicating the
strength of an incoming RF signal, this output allows the assessment of RF link quality and
transmission range. The RSSI pin output voltage is typically 0.9 V with no RF signal, rising to
typically 2.6 V at maximum signal. The external loading should be kept to a minimum since
the RSSI output source impedance is around 20 kOhm. The following shows a typical RSSI
characteristic:

3. APPLICATIONS INFORMATION

3.1 Module Mounting

The modules may be mounted in vertical or horizontal position to the user board of the
application device (load module). In a vertical position, the module pins can be directly
connected to the user board through suitable PCB holes. Optionally suitable female strip

connectors can be used, available e.g. from Conrad Electronic GmbH (Ordering No.
73 92 43). Additional module fixing may be necessary in rough environments.

The following features have to be available on the motherboard:

- Load circuit, i.e. power switches or serial interface driver (connected to RCM functional

output pins OUT_0..3)

- Power supply for the receiver module (GND_0, GND_1, VCC) and for the load circuit

- Configuration of the receiver firmware (connecting of input pins CODE_0, CODE_1 and

CODE_2)

- Programming pushbuttons for channel storing (connecting of input pins LRN and CLR)

- If needed, Learn Mode indication circuitry: LED(s) for providing optical feedback and/or

a load output decoupling logic

- External connectors

3.2 Antenna Mounting

Positioning and choice of receiver and transmitter antennas are the most important factors in
determining system transmission range. The RCM 152 receiver modules are supplied without
antenna as a standard. For mounting the antenna, the following notes should be considered to
optimize the system performance:

a) Mounting a 1/4-wave whip antenna:

A whip antenna enables a very compact receiver unit with good radio reception characteristics.
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 from all metal parts, PCB strip lines and
fast logic components (e.g. microprocessors). To avoid radio frequency noise from the
motherboard, which desensitizes the receiver, PCB strip lines on the user board should be
designed as short as possible, and using PCB ground plane layer is also recommended.
Note that 868 MHz whip antennas do not show any directional effects under free-field radio­wave propagation conditions (spot-wise radiator). The RSSI voltage output can be used for
evaluating the influence of intuitive RF optimizations.

For a good antenna performance don’t roll up or twist the whip and please draw
attention to an overall whip distance of at least 10 mm (20 mm is better) from any
PCB strip, ground plane and conductive part or electric part.

RCM 152 User Manual V1.31

Figure 13: Specification of the RCM whip antenna

b) Mounting an external antenna:

For mounting the receiver at bad RF locations (e.g. within a metal cabinet), an external
antenna has to be used. After resoldering the pre-installed whip antenna, the external antenna
can be connected to the equipment by a 50-Ohm coax feeder with Teflon insulation as follows
(connect the inner cable to the resoldered hole, and solder the shielding as short as possible to
the RCM Groundplane, length of insulation max. 4 mm):

RCM 152 User Manual V1.31

3.3 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.

notification of a particular range that will be attainable by a particular application.

The following figures for expected transmission range are considered by using a PTM, a STM or
a TCM radio transmitter device and the RCM or 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

• Brick walls / aerated concrete: Typically 20m range, through max. 3 walls

• 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

A summarized application note to determine the transmission range within buildings are
available as download from www.enocean.com.

Attention for US applications: Please note that 868 MHz is used in the United States
of America by trunk radio also. A decrease of transmitter range should be
considered, mainly near to radio beacons of fire brigades.

RCM 152 User Manual V1.31

3.4 Power Supply Requirements

In order to provide a good radio performance, a great attention must also be paid to the
power supply and a correct layout and shielding, especially when this power supply also
supplies possible sources of interference like oscillators or other digital circuits at the same
time. Digital switching is very fast and creates high frequency interferences.
A star-connected topology and at least a 10uF low-ESR tantalum or similar ceramic capacitor
is recommended to be added as close as possible to module, between the module supply pin
Vcc and GND, together with a low DC-resistance (<1 Ω) EMI-suppressor, like a ferrit bead e.g.
multi layer suppressor type MLS0805-4S7-102 from Ferroxcube, series feed between the
board supply pin input and the output of the power supply rail.
The ripple on the 5V (±5%) power supply rail should be below 10mVp-p.

3.5 LMI Output Connection

Example of a learning status indication by LEDs at 2 channels mode with decoupled loads
during learning mode (the decoupling of the load is only necessary if status indication through
connected actors is not appropriate). Note: LMI is Active High during learning mode; OUT_0
and OUT_1 are open collector outputs (Active Low).

3.6 CE Approval Requirements

The modules bear the EC conformity marking CE and conforms to the R&TTE EU-directive on
radio equipment. The assembly conforms to the European and national requirements of
electromagnetic compatibility. The conformity has been proven and the according
documentation has been deposited at EnOcean. The RCM modules can be operated

without notification and free of charge in the area of the European Union, in
Switzerland, in Cyprus, in Czech, in Estonia, in Hungary, in Latvia, in Lithuania, in
Malta, in Poland, in Romania and in Slovenia. The following provisos apply:

©EnOcean GmbH

Page 17 of 20

RCM 152 User Manual V1.31

• EnOcean RF modules must not be modified or used outside their specification
limits.

• EnOcean RF modules may only be used to transfer digital or digitized data.
Analog speech and/or music are not permitted.

• The final product incorporating EnOcean RF modules must itself meet the
essential requirement of the R&TTE Directive and a CE marking must be affixed
on the final product and on the sales packaging each. Operating instructions
containing a Declaration of Conformity has to be attached.

• If transmitters are used according to the regulations of the 868.3 MHz band, a
so-called “Duty Cycle” of 1% per hour for each transmitter must not be
exceeded.

3.7 FCC/IC Approval Requirements

Because of the very low radiated field strength on average, the 868.3 MHz EnOcean
radio technology can be approved in the USA and in Canada.

In the US approval of receivers is not

necessary in general. On a voluntary base an US

representative can last out a "Declaration of Conformity" (DOC) together with technical
documentation. The measurements has to be done by a FCC notified body with respect to FCC
Part 15B. Product labeling should be according Part 15 of the FCC Rules, page 11.

In Canada receivers < 960 MHz must be approved! The measurements of the finished
device has to be done by a IC notified laboratory with respect to RSS-210 of Industry Canada,
section 7. The receiver has to be labeled with IC approval number.

Please note: 868 MHz frequency range is used by Trunk Radio in the US. Since a clear
reduction of transmission range is to be expected near to trunk radio stations, range
tests at the system’s target location should categorically be performed before
notification of a particular range in the US and Canada!

4.2 Field Intensity Meter EPM 100

The EPM100 is a mobile field-intensity meter that helps the engineer to find the best
installation positions for sensor and receiver. It can also be used to check disturbances in links
to already installed equipment. The EPM100 displays the field intensity of received radio
telegrams and interfering radio signals in the 868MHz range.

The simplest procedure for determining
the best installation positions for the
radio sensor/receiver:

• Person 1 operates the radio
sensor and generates pushbutton
radio telegrams.

• Person 2 checks the received field
intensity on the meter display to
find the optimal installation
position.
