Information about the radio system
2.1
General information and functionality
With its extensive product range, the radio system "Easywave" is the complete system
for all applications in building services engineering.
The 868 MHz wave band with its division into sub-bands (e.g. sub-band 868.0 MHz to
868.6 MHz) and different duty cycles is ideally suited for sophisticated tasks. In the ISM
wave band (ISM= Industrial, Scientific, Medical), transmission only takes place for a few
hundred milliseconds with outputs of less than 1 milliwatt (max. 25 milliwatt poss.).
To be able to address a radio receiver, you first have to teach in the Easywave send
code. After the teach-in process, the receiver can be shut off by the transmitter or the
gateway.
The send code of an Easywave transmitter has a length of 32 bit and contains a serial
number as well as a keycode. The serial number serves to identify the sender. The
keycodes A, B, C and D are automatically assigned to the functions of the set operating
mode by the receiver.
In dependence on the selected operating mode, the individual keycodes of a serial
number are automatically assigned receiver functions upon teach-in.
For example, only one of four send buttons must be programmed with a receiver for a
shutter control in order to be able to use the functions UP/STOP/DOWN.
For detailed information about the keycodes and the receiver's interpretation of the
keycodes, see the respective instruction manuals.

Operating modes
ON/OFF (1-button operation)
With 1-button operation or so-called toggling, the switching status of the receiver
changes with every push of the button:
1. Send: ON
2. Send: OFF
3. Send: ON
…
Each keycode can be programmed and used separately. There is no automatic as-
signment.
