1. GENERAL DESCRIPTION
The multifunctional receiver modules RCM 110 and RCM 120 are 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”).
Serial Data Communication via Receiver Module RCM 120 (all EnOcean RF signals):
• Serial data link from all radio signals transmitted from PTM, STM, TCM and CTM radio
modules (9600 bps, 1 start bit, 1 stop bit)
• This interface enables a simple realization of a Gateway to existing control and
monitoring systems
• This interface enables any desired actor functionality by the user, e.g. by
connecting to a following microcontroller (the output control logic can be
easily and flexible programmed by the user)
RCM 110 output switching functionalities (controlled by PTM radio signals):
• Basic signal output functions “switching” (On/Off): 1, 2 or 4 channels
• Basic signal output function “dimming”: On/Off (pushbutton operated quickly) and PWM
50 kHz (pushbutton pressed for a longer time) with switch-off value memory
• Scene selection control: ALL On/Off, 6 scene memories
• Learning procedure for EnOcean transmitters, easy to operate
RCM 120 output switching functionalities (controlled by PTM radio signals):
• Basic signal output function “pushbutton”: 1 channel
• Basic signal output function “tubular motor control” (UP/DOWN with slat acting):
1 or 2 channel
• Learning procedure for EnOcean transmitters, easy to operate

1.2 Typical Applications
• Building installation
• Industrial automation
• Consumer Electronics
The RCM modules are part of a powerful RF system solution from EnOcean for operation and
control applications. Because the RF transmitters are self-powered (no batteries),
maintenance-free RF systems can be implemented.
The RCM modules operate together with the following further EnOcean components: PTM
(batteryless radio switches), STM (batteryless radio sensors), CTM (remote control) and TCM
(bi-directional IT interface)

HRC radio telegrams from PTM, CTM or TCM modules).
Note: Mode 0 (Serial Interface) provides an optional to use, simple teach-in
functionality for PTM, STM, CTM and TCM modules:
During the receiver is in learn phase the IDs of all arriving transmitter telegrams are stored.
All received EnOcean telegrams are outputted at the serial interface in Learn Mode and in
Operating Mode. Those with known ID are marked in addition by a dedicated Bit (see H_SEQ
at chapter 2.5).
Please note, that cyclic sending transmitters can be learned inadvertently, especially
when using more than one sensor! For further application information please draw
attention to the STM 100 User Manual, chapter 3.8 „Learn Pushbutton“.

2.5 RCM 120 Serial Interface (Operating Mode 0)
When the receiver is in “Serial Interface” mode, it transfers out data blocks of information
from the received RF telegrams. All received EnOcean telegrams are transferred.
Telegrams of transmitters learned by the receiver are signed if this procedure is used. The
data block format is explained later in this document; it depends on the type of sensor from
which the telegram has been received.
The serial telegram is sent 40 ms after reception of the first of typically three radio sub-
telegrams. While transmitting data through the serial interface (about 15ms) the module is not
able to receive radio telegrams. Sub-telegrams received from one transmitter with same
content within 40 ms are treated as one telegram (only one serial transmission). There is a
buffer for 4 telegrams. A buffer is blocked for 40 ms after reception of the first sub-telegram.
If more than 4 different telegrams (repeated telegrams are also treated as different telegrams
in RCM120) are received within 40 ms further telegrams will be ignored until a free buffer is
available.

2.5.5 Detailed description of STATUS field
If ORG = 5 (Telegram from a PTM switch module):
7 0
Reserved T21 NU RP_COUNTER
Reserved (2 bit) For future use
T21 (1 bit) T21=0 ÆPTM switch module of type 1,
T21=1 ÆPTM switch module of type 2
NU (1 bit) NU=1 ÆN-message, NU=0 ÆU-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 RCM 120 or TCM 120 serial receiver mode in
combination with the TCM 110 repeater module, please ensure that no serial command
interpretation error may occur at the connected control unit. A toggle signal means that the
same telegram (from e.g. PTM 100, PTM 200 or STM 100) is sent for switching something on
and off. If e.g. the light is switched on by means of a RCM 120 receiving the I-button telegram
from a PTM 100, the repeated telegram (delay <100ms) may switch off the light again. It is
therefore mandatory to interpret the RP_COUNTER field as described in the RCM 120 User
Manual. 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 1 (e.g. PTM 100) do not support interpretation of operating more
than one rocker at the same time:
• N-message received ÆOnly one pushbutton was pressed.
• U-message received ÆNo pushbutton was pressed when activating the energy
generator, or more than one pushbutton was pressed.
PTM switch modules of Type 2 (e.g. PTM 200) allow interpretation of operating two buttons
simultaneously:
• N-message received ÆOnly one or two pushbuttons have been pressed.
• U-message received ÆNo pushbutton was pressed when activating the energy
generator, 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!
If ORG = 6, 7 or 8 (all other telegrams):
7 0
Reserved RP_COUNTER
Reserved (4 bit) For future use
RP_COUNTER (4 bit) Repeater level: 0 is original message (not repeated)

2.6 Learning Modes
Four different learning modes are implemented within the RCM 110 and the RCM 120 modules:
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: Transmitter Learning Mode entered via Configuration Remote
Control (CTM module in CRC operating mode) or via Central Unit Interface (TCM): The
receiver sensitivity is not limited. Learning of repeater-powered signals is enabled. The
transmitters telegrams have to be triggered 3 times within 2 seconds to avoid
inadvertent learning. RLM can only be entered within a time of approx. 30 minutes after
receiver power up to make a running system safe against sabotage.
4.) Learning Mode SSLM (RCM 110 only): Scene Switch Learning Mode entered via
SSLM pin: PTM transmitter modules are learned as scene switches. The receiver
sensitivity is limited to in-room operation, learning of repeater powered signals is
disabled. All switch rockers will have a fixed function; for learning of the whole switch,
only one rocker has to be operated.
Indistinct signal or pin configurations are ignored at all times. Within the learning procedure,
the learning mode cannot be changed.
2.7 Learning of Radio Transmitters
Please also draw attention to the notes about learnable transmitters in chapter 2.3 and 2.4
“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: The remote control must be operated within a
distance of max. 0.5 m to the receiver. A specific selection method can be used
(multiple pressing of the control pushbutton) when two receivers are very close
together and have been set into learning mode at the same time.
- Via SSLM Pin: Contact to GND longer than t = 0.5 sec. In multi-channel receiver
modes, all channels are selected (scene switch operates all channels).
