1 Introduction
This manual describes the functions of the device named GW1x776 “Easy 8 channel EIB RF receiver” and
how to use the ETS configuration software to change the settings and configurations.

4
2 Application
The 8 channel EIB RF receiver is a device that allows the Chorus RF system command and control devices
to communicate with a KNX/EIB system, which hence allows the Home Automation Konnex system to be
extended using RF control devices.
This device is in fact fitted with 8 EIB output channels, each of which can be configured independently to
perform different functions. Up to 4 different RF command sources (transmitters) can be connected to each
channel which manages a total of 32 channels of the RF remote control, RF pushbutton panel, IR with
twilight switch RF movement detector, 2 RF channel input modules, etc.
The functions each channel is able to perform are those typical to an input interface, that is ON/OFF
commands, shutter control, dimmer control, scene management, priority commands.
Not all RF control devices can perform the above listed functions, so before starting to configure the device
using the ETS software, please read the INSTALLATION AND USER MANUAL, which lists all the
commands that the different RF control devices can perform.
This manual refers solely to the configuration using the ETS software. Please refer to the INSTALLATION
AND USER MANUAL supplied with the product for instructions on how to configure the RF Receiver with RF
control devices.
2.1 Limits to the associations
Maximum number of group addresses: 100
Maximum number of logical associations: 100
This means that it could be possible to define maximum 100 group addresses and realize maximum 100
associations between group addresses and communication objects.

3 “Settings” menu
Here it is possible to configure the programming mode between ETS mode (S-Mode) and Easy mode by the
Easy controller software (Kit GW90837, Kit GW90838, GW90840) see Diag 3.1.
Diag 3.1
3.1 Parameters
¾3.1.1 Programming mode
This parameter determines the programming mode of the device:
•ETS mode
Select this value if you want to configure the device with ETS (S-Mode); all the configuration parameters
are now visible.
•Easy mode
Select this value if you want to configure the device with the Easy controller software.
Remember to download the application program with this value selected before using the device by the
Easy controller software if you have already used the device in an ETS project.
3.2 Communication objects
There are no communication objects enabled by the Settings menu.
For the sake of simplicity, the Channel 1, Channel 2, Channel 3, Channel 4, Channel 5, Channel 6,
Channel 7 and Channel 8 menu options will be described in the following chapters once only (referring to
the general menu Channel x) as all menus carry the same options.

5.2 Communication objects
The switching function makes the following communication objects visible (See Diag. 5.2.):
Diag. 5.2
¾5.2.1 Ch.x – Switch
Using these communication objects, the device sends ON/OFF commands to the bus after receiving
load activation/deactivation commands from the RF control devices associated to the general channel x.
The enabled flags are C (communication), R (read by bus) and T (transmission) .
The standard format of the object is 1.001 DPT_Switch, the size of the object is 1 bit and the information
it sends is On/Off or more generally 1/0.
¾5.2.2 Ch.x – Status feedback
Through this communication object the device receives status feedbacks for the devices it controls,
generally actuators, so that it is always updated about their status and therefore able to manage them
correctly. Please note that the use of this object is essential in order for the cycle switching to function
correctly when the RF control device associated to the general channel x is a 2 RF channel input module
configured for cycle switching.
The enabled flags are C (communication), W (written by bus).
The standard format of the object is 1.001 DPT_Switch, the size of the object is 1 bit and the information
it contains is ON/OFF status or more generally 1/0 status.

Using this communication object, the device sends brightness increase/decrease commands to the bus
according to the command received from the RF control devices associated to the general channel x.
The coding of this type of command allows you to differentiate between increase and decrease, and also
the percentage value of the same variation; in this specific case, according to the RF control received,
“increase to 100%” (decrease to 0%)” of the brightness value commands and stop control commands
are sent. This allows for a faster or slower dimmer action according to the manufacturing features on the
controlled device.
The enabled flags are C (communication), R (read by bus) and T (transmission) .

Diag. 9.1
9.1 Parameters
¾9.1.1 Scene 1
Here you can set the value for scene 1 that is to be enabled/disabled after receiving a command from
the RF devices associated to the general channel x; the settings range from 0 to 7.
The value set for this option is important as the output devices (actuators, dimmers etc.) are usually able
to manage more than one scene, which is identified by the command value that is received; it is
recommended to configure this option correctly, making sure the number is assigned according to the
scene that you intend to manage with scene 1 on the general channel x to which it refers.

Here you can set the value for scene 2 that is to be enabled/disabled after receiving a command from
the RF devices associated to the general channel x; the settings range from 0 to 7.
The value set for this option is important as the output devices (actuators, dimmers etc.) are usually able
to manage more than one scene, which is identified by the command value that is received; it is
recommended to configure this option correctly, making sure the number is assigned according to the
scene that you intend to manage with scene 2 on the general channel x to which it refers.
