2. 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.
2.2 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.

RGK02 Operating Instructions
8
ON/OFF (2-button operation)
With 2-button operation, the receiver switches directly ON and OFF.
Keycode A: ON Keycode C: ON
Keycode B: OFF Keycode D: OFF
A, B as well as C and D are assigned automatically. Only one of these keycodes must
be programmed. Both groups can be used separately.
TIMER
In timer mode, the receiver switches ON for 7 minutes after receiving a programmed
send code and OFF again after expiration of this time.
Keycode A: ON (for 7 minutes) Keycode C: ON (for 7 minutes)
Keycode B: ON (for 7 minutes) Keycode D: ON (for 7 minutes)
Each keycode can be programmed and used separately. There is no automatic as-
signment.
DEADMAN FUNCTION
In deadman function, the receiver switches for the duration of the transmitter operation.
Due to the maximum duty cycle, all transmitters automatically switch off after 36 sec-
onds. With the gateway, the system switches off after 31 seconds already.
Keycode A: ON (max. 31 seconds)
Keycode B: ON (max. 31 seconds)
Keycode C: ON (max. 31 seconds)
Keycode D: ON (max. 31 seconds)
Each keycode must be programmed and used separately. There is no automatic as-
signment. Simultaneous use of several channels is not possible.
UP/DOWN (2-button operation)
This operating mode is only available with receivers for shutter control featuring two
interlocked relay outputs. Here, UP stands for switching of the 1st relay, DOWN for
switching of the 2nd relay.
Parallel switching of both outputs is not possible. The relays automatically
cut off again after 90 seconds.
The STOP command is triggered by transmission of the counter-direction.

RGK02 Operating Instructions

For example, if the shutter moves UP (A), it is stopped initially when pressing the button
for the opposite direction (B) and DOWN when pressing the button (B) again.
Keycode A: UP/STOP Keycode C: UP/STOP
Keycode B: DOWN/STOP Keycode D: DOWN/STOP
A, B as well as C and D are assigned automatically. Only one of these keycodes must
be programmed. Both groups can be used separately.
UP/STOP/DOWN (3-button operation)
This operating mode is only available with receivers for shutter control featuring two
interlocked relay outputs. Here, UP stands for switching of the 1st relay, DOWN for
switching of the 2nd relay. The relays automatically cut off again after 90 seconds.
Parallel switching of both outputs is not possible.
The STOP command is triggered by transmitting the keycode C or D.
Keycode A: UP Keycode C: STOP
Keycode B: DOWN Keycode D: STOP
A, B as well as C and D are assigned automatically. Only one of these keycodes must
be programmed.
IMPULSE
With this operating mode, the relay output is switched for 1 second upon receipt of a
programmed send code and afterwards releases again, independently of how long the
manual transmitter is operated.
Keycode A: ON (1 second) Keycode C: ON (1 second)
Keycode B: ON (1 second) Keycode D: ON (1 second)
Each keycode can be programmed and used separately. There is no automatic as-
signment.

4 Functions and object properties
KNX programming and assignment of the Easywave radio products to the individual
objects (programming and deleting) is done with the ETS.
4.1 System objects
The three system objects are required for the administration of the Easywave send
codes. These objects are permanently integrated in the system and cannot be changed.
Valid group addresses must be assigned to use the system objects.
The following system objects are available:
641 (1 byte): "Teach channel" (see chapter 4.1.1)
Teaching in a handheld transmitter on the memory slots 1-128
642 (1 byte): "Delete channel" (see chapter 4.1.2)
Deleting a handheld transmitter on the memory slots 1-128
643 (1 bit): "Delete all channels" (see chapter 4.1.3)
Deletes all programmed manual transmitters
After creating and assigning the group addresses, these can be addressed directly via
the ETS group monitor.

RGK02 Operating Instructions
14
4.1.1 Teaching in a channel
The system object 641 serves for teaching in Easywave send codes.
The teach-in process is initiated by transmitting the desired memory slot number (value
from 1 to 128) to the respective group object.
1. Open the group monitor (menu Diagnosis/Group telegrams)
and click on Read/send.
2. In the menu "Read/send values",
enter the group address of the sys-
tem object "Teach in channel" (e.g.
1/1/1).
3. In the field "Value" enter the de-
sired memory slot number and click
on "Write". Please note that the
number of the memory slot repre-
sents the assignment to the corre-
sponding receive object at the
same time (see point 4.3.2)
4. The LED on the gateway lights up
red. Now press the desired trans-
mitter.
Once the teach-in process is com-
pleted, the LED goes off.
5. Repeat these steps for each addi-
tional transmitter.
ATTENTION!
If you teach in a transmitter double on a memory slot (value), the already programmed
send code is overwritten.
If you teach in the same transmitter on different memory slots, the gateway will only
execute the function of the lowest channel.

4.1.2 Deleting a channel
The system object 642 serves for deleting specific Easywave send codes.
Direct deletion of a send code is initiated by sending the value for the memory slot (1-
128) to the corresponding group object.
1. Open the group monitor (menu Diagnosis/Group telegrams)
and click on Read/send.
2. In the menu "Read/send values",
enter the group address of the sys-
tem object "Delete channel" (in this
case 1/1/2).
3. In the field "Value" enter the mem-
ory slot number to be deleted and
click on "Write".
4. The corresponding memory slot is
deleted and the gateway will no
longer react tot he corresponding
transmitter.
5. Repeat these steps for each addi-
tional channel to be deleted.

RGK02 Operating Instructions
16
4.1.3 Delete all channels
The system object 643 serves for deleting all programmed Easywave send codes.
Deletion of all send codes is initiated by sending [1] to the corresponding group object.
1. To do so, open the group monitor (menu Diagnosis/Group telegrams) and clock
on Read/send.
2. In the menu "Read/send values",
enter the group address of the sys-
tem object "Delete all transmitters"
(e.g. 1/1/3).
3. Change the value to [1] and click
on "Write"
4. Now all send codes are deleted
and the gateway will no longer re-
act to radio signals until new
transmitters are programmed.
ATTENTION!
There is no prompt for confirmation! All transmitters are permanently deleted!
A restoration of the assignment is not possible.
Therefore, only assign a group address to object 643 if you really need it and then de-
lete the group address again!

4.2 Creating receive objects
The receive objects serve for the implementation of Easywave operating modes in the
KNX Bus. Altogether 128 memory slots are available for Easywave serial numbers.
The receive objects are divided into 16 groups (E to T); each group has eight receive
functions. By default, only the 8 receive functions of group E are activated. If more re-
ceive functions are required, further groups in the menu "Receive groups" must be set
to "Use".
Afterwards, the newly selected receive group is available for function assignment.
The receive functions are numbered consecutively (1 to 128). The respective channel
number is permanently assigned to the memory slots for the Easywave send codes.
For example, the functions of receive object 4 can only be controlled by the Easywave
transmitter programmed on slot 4.

RGK02 Operating Instructions
18
The receive objects can be assigned to one of the following KNX functions:
−Toggle
−Switch
−Dim
−Shutters
−Set value
−Signal
4.2.1 Toggle
Data type 1 bit
Number of objects 4 (A) toggle, (B) toggle,
(C) toggle, (D) toggle
Object behaviour
upon receiving (A): Toggle [1] or [0]
(B): Toggle [1] or [0]
(C): Toggle [1] or [0]
(D): Toggle [1] or [0]
In this operating mode, four 1 bit objects are created for the respective channel. These
represent the keycodes A, B, C and D of one Easywave serial number.
If one of the keycodes is received, the gateway alternately sends
[1] or [0] to the respective group objects of the KNX bus.

RGK02 Operating Instructions
19
After pressing the corresponding button of a programmed transmitter, the functions are
transferred to the KNX bus by the gateway.
A corresponding 4-channel transmitter is required to be able to use all four objects of a
channel.
4.2.2 Switch
Data type 1 bit
Number of objects 2 (A/B) switch, (C/D) switch
Object behaviour
upon receiving (A/B): (A=[1]; B=[0])
(C/D): (C=[1]; D=[0])
In this operating mode, two 1-bit objects are created for the respective channel. These
represent the keycodes A, B, C and D of one Easywave serial number.
If the keycode A or C is received, the gateway sends [1] to the respective group objects
of the KNX bus. If the keycode B or D is received, the gateway sends [0] to the respec-
tive group objects of the KNX bus.
After pressing the corresponding button of a programmed transmitter, the functions are
transferred to the KNX bus by the gateway.
A corresponding 4-channel transmitter is required to be able to use all four objects of a
channel.

Short-time object: Press button < 1.6s
(A/B): (A=[1]; B=[0]) Switch
(C/D): (C=[UP]; D=[DOWN]) Dim
Long-time object: Press button > 1.6s
(A/B): (A=[UP]; B=[DOWN]) Dim
Parameters Dim stages
Function A/B: [1 to 64] [Dim] or [Dim and switch]
This operating mode serves to address KNX dimmers. When receiving the keycode A
or C, the command dim up is sent to the bus, when receiving the keycode B or D, the
command dim down.
By setting the parameter [dim and switch], a short-time object for switch commands for
channel A/B is created in addition to the dim object. The switch command for the key-
codes A/B is then triggered when the button is pushed <1.6 seconds. If the button is
pressed longer, the dim function is used.
Attention! If the execution of this function should lead to interference on the radio line,
the secure distinction between long-time and short-time objects cannot be guaranteed.
In case of an error, a switch command would be sent instead of a dim command. This
leads to the complete ON/OFF of the KNX actor, independent of the current dim stage.
This option is not available for dimming with the buttons C/D.
