2.4 PTM 200 Serial Data Communication via Receiver Device RCM 120
The RCM 120 Receiver Device of EnOcean enables standard asynchronous communication to
a microcontroller or personal computer with a decompressed and simple data structure (9600
bps, 1 start bit, 8-bit data byte with LSB first, 1 stop bit).
When the RCM 120 receiver is set to Mode 0 “Serial Interface”, it transfers out data blocks of
information from all received EnOcean radio telegrams (from PTM-, STM-, TCM- and CTM-radio
devices). For a complete transmitter message, a telegram of 14 data bytes is transferred via
the serial link.
The data block format is explained in detail in the RCM 110/120 User Manual
.

2.5 Basic Switching Features via Receiver Devices RCM 110 and RCM 120
The multifunctional RCM 110 and RCM 120 Radio Receiver Devices are used to receive
and process PTM-telegrams generated and transmitted by EnOcean radio transmitters. Via
functional control outputs (“open collector”), these devices can be easily integrated into
control and switching units for the implementation of different application-specific system
solutions.
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 action):
