This setup guide covers the physical installation of the KNX 100G and KNXnet/IP tunneling from a PC to a KNX network during
conguration and commissioning.

The KNX 100G allows better integration of control with KNX building management systems (BMS). The product serves as a
gateway for control systems and ETS software to the KNX bus, and it is designed to be installed onto a DIN rail with a width of 1
unit (18 mm).

Power is supplied via the KNX bus; an external power supply is not necessary. The KNX bus can be accessed from any point on
the LAN. The IP address can be obtained by a DHCP server or by manual conguration. There are ve simultaneous connections
possible for access via KNXnet.

KNX 100G Network Installation

1. Using a certied KNX twisted pair cable, connect to the

KNX BUS located on the top of the device (see gure 3).

2. Connect an ethernet cable between the Ethernet port

located at the bottom of the KNX 100G and the local

network.

3. Congure the KNX 100G using ETS.

4. Congure your Extron Control System using the Extron

driver targeted at your congured KNX 100G.

NOTE: Engineering Tool Software (ETS) is an application

for designing, commissioning, and debugging KNX
installations. Click this link to view and purchase ETS
for your KNX setup. KNX system setup should be done
by a certied KNX professional.

KNX 100G Setup

1. Add KNX 100G Interface Within ETS

Within ETS, the KNX 100G interfaces can be selected and setup via “Bus Interfaces”.

NOTE: ETS can access congured KNX 100G interfaces without a database entry if the default settings are compatible with

the KNX installation. If the KNX 100G setup does not comply with installation conditions, it must be configured within an
ETS project. See Configure Interface Properties on page 4.

After connecting the KNX 100G to the LAN and the KNX bus, the device should automatically appear in ETS within the “Bus”
menu under “Discovered Interfaces”. By double clicking on the discovered interface, it will be selected as the current interface. On
the right side of the ETS window, all specic information and options of the connection appear (see gure 5).

2. Setup Individual Address for Tunneling

The device’s name and “Individual Address” can be changed within your ETS project. The KNX 100G has an individual address
which can be used to access the device.

The device supports up to ve connections for control. Each connection is associated with one of the ve individual addresses
in the device. The addresses can be assigned via ETS. Telegrams sent to the bus contain a sender address from one of the ve

additional addresses, and response telegrams can be transmitted to respective clients.

Additional individual addresses must be selected from the address range of the bus line in which the interface is installed and may
not be used by another device. The individual KNX 100G address and the addresses for additional tunneling connections can be
changed within the ETS project after the device has been added to the project.

Figure 5. Changing Device Address in ETS

3. Configure Interface Properties

After adding the KNX 100G to a project, you can change the Individual Address and IP setting in Properties (see gure 7
below). In ETS 4, additional individual addresses will appear in the Topology view.

Within the ‘Settings’ overview, each individual KNX address and the device’s name can be changed. ‘Properties’ will appear on
the right side of the ETS window after clicking on the KNX 100G device entry within the project’s topology view. Click on the list
entry and type in the desired address into the Individual Address texteld to change an individual address (see 1 in Figure

6). If the texteld frame switches to color red after entering the address, the address is already taken within your ETS project.

NOTE: Make sure none of the individual KNX addresses are in use within the KNX installation.

If the physical KNX addresses of the tunneling connections have been assigned via ETS, a manual address setting on

the device is not allowed.

The IP network specic options of the KNX 100G can be changed. In the ‘Properties’ window, click on the ‘IP’ tab. Change

Obtain an IP address automatically to Use a static IP address to set the IP address, subnet mask, and
default gateway freely 2.

4. Program the KNX System

Via the KNX Bus

The device only needs to be connected to the KNX bus. ETS requires an additional interface to have access to the bus.
Both the individual address and the entire application can be programmed via the KNX bus. Programming via the bus is
recommended if no IP connection can be established.

Via KNXnet/IP Tunneling

No additional interface is required. Programming via KNXnet/IP Tunneling is possible if the device already has a valid IP
conguration. The device is displayed in the interface conguration of ETS and must be selected. The download is executed
via ETS.
