Leviton KNX Gateway
Cat. No. KNXGW-000
The KNXGW Leviton KNX Gateway allows a Leviton Omni automation controller (Omni LTe, Omni IIe, or OmniPro II) to
communicate with and control KNX devices on an existing KNX bus. Lighting, temperature and energy management, and
motors (window coverings, shades, shutters, etc.) are among the many KNX devices that can be controlled. The KNX
Gateway provides an interface between the Omni controller and the KNX network by mapping specific data points of each
KNX device to a unit or thermostat number on the Omni controller.
The following is an overview of the inputs and outputs on the KNX Gateway.
On the top of the KNX Gateway there are two LEDs:
1.
Green LED:
Power Status LED. LED is illuminated when the KNX Gateway is powered either through a PoE Ethernet
connection or by providing 12-24V DC.
2.
Red LED:
Reset/Service LED. LED is normally off. LED will blink or illuminate during reset procedure.

Install the KNX Gateway as follows:
1.
Install the KNX Gateway in a suitable distribution box fitted with 35mm DIN rail.
2.
Connect the KNX bus to the KNX Gateway using the KNX Bus Connection terminals on the KNX Gateway.
3.
Power the KNX Gateway by supplying 12-24VDC to the power terminals on the KNX Gateway.
Alternatively, the KNX Gateway can also be powered using a Power Sourcing Equipment (PSE) device, such as a PoE
network switch, hub, or power injector which provides the power. A Cat-5 or better (4-pair) cable is required. Run the
Cat-5 cable between the location of a PoE network switch, hub, or power injector and the location of the KNX Gateway.
Terminate both ends of the Cat-5 cable with 8-position modular connectors to make a standard straight through network
patch cable. Plug the cable into the Ethernet Port (PoE) the KNX Gateway.

b.
Connect the DB9 connector to the RS-232 Port on the KNX Gateway. Connect the end of the modular cable to one of
the built-in serial ports on the Omni controller. Configure the function of serial interface on the Omni controller to "KNX".
It is important that the KNX programmer make available all of the device parameters that you will need. This is especially
important in the case of thermostats since not all of the features for a standalone thermostat would need to be configured
(e.g. setpoints being set remotely). If the KNX programmer does not assign this feature a Group Address, you will not be
able to associate it with the Omni controller through the KNX Gateway.
The configuration for the KNX Gateway is performed through a built-in web interface.
1.
Connect the Ethernet Port of a PC to the KNX Gateway using a standard network cable. If the KNX Gateway is being
powered by a PSE device (e.g. PoE switch), connect the Ethernet Port of the PC to the same PSE device.
a.
Temporarily change the network settings of the PC (IPV4 protocol), as follows:
• IP
address:
192.168.0.100
• Subnet
mask:
255.255.255.0
• Default
gateway:
192.168.0.110
b.
Once your computer is on the same subnet as the KNX Gateway, you can access the web interface by opening a
supported web browser and entering the following IP address into the address bar:
http://192.168.0.110
c.
You will be prompted with a login screen. By default, the user name is
admin
and the password is
admin
.
After logging in to the web interface of the KNX Gateway, use the Menu tree to configure the various parameters of the KNX
Gateway. Whenever a change is made to the configuration, the "Save" (disk icon) button in the upper-right side of the page
becomes red. It will stay red until the next auto-save process (about every 5 minutes). If you need to power down the KNX
Gateway while the "Save" button is still red, press this button to save the project; otherwise, the changes that were made
after the last auto-save will be lost.
After the new network settings have been made and saved:
a.
If your computer’s network settings were previously changed to access the KNX Gateway web interface, you can now
set your computer’s network settings back to correct settings for your existing network.
b.
You can now access the KNX Gateway using the new IP address.
Backup/Restore Page:
Allows you to
Export
a backup for the configuration file that is stored in the KNX Gateway. This
file will be useful if you ever need to replace the KNX Gateway or reset it to its factory default settings. You can also import
a previously exported configuration file. This is useful if you needed to replace the KNX Gateway or reset it to its factory
default settings. The
Reset
option allows you to restore the KNX Gateway to its factory default configuration.
After the controller’s network settings have been entered, press the Start button to initiate communications between the
Omni controller and KNX Gateway.

DESCRIPTION
CONFIGURING THE KNX GATEWAY
SETUP
KNX
OVERVIEW
INSTALLATION
The Setup menu allows you to configure the network settings, make a backup of the configuration file, restore from a
previous backup of a configuration file, reset the KNX Gateway to its factory default settings, configure the date and time
settings, update the software, and obtain system information about the KNX Gateway.
Network Page:
Allows you to assign an IP address, Subnet mask, Gateway, and DNS to match your existing network.
Before building rules (see the section entitled
Gateway Rules
) between devices on the KNX bus and devices on the Omni
controller (which were added under the section entitled
Leviton
), you must first assign the KNX Gateway a Physical Address and
add the KNX objects (specific attributes, typology, encoding, etc.) to the KNX Gateway for each KNX Group Address used on the
KNX bus. It is recommended that you obtain an export of the ETS project file in OPT format (this file has an extension of
.ESF
)
from the KNX programmer. This file can be imported into the KNX Gateway to automatically add KNX objects and attributes.
Otherwise, KNX objects can be manually added. In this case, it is recommended that you obtain a "Group Addresses Details
Report" from the KNX programmer. This can be printed from ETS software using the Print function.
Add KNX Objects:
Allows you to manually add KNX objects to the KNX Gateway. When objects are manually added, you must
enter the name (user friendly name for identifying the device/function), read and/or write function, command address, state
address, and length for the type of encoding.
Click
Add
to add a new object. Click
Save
to save the added objects.
ETS Import Rules:
For each KNX Group Address in the ETS project, the import procedure looks for a matching rule by keyword
and type. When found, the rule for encoding is assigned to the newly created KNX object. If a rule is not found, you will be
prompted to specify missing information manually.
