Setting up KNX building functions

5.1

Project planning KNX devices

The Gira G1 is a product in the KNX system and corresponds to the KNX guide-
lines. Detailed technical knowledge is a prerequisite for correct understanding.
The Gira G1 can be used as a multifunctional room control unit for an existing or
newly installed KNX system.
Start-up is carried out using ETS 4.2 or later.
Note
The KNX product database and technical documentation can be found on the
Internet at www.download.gira.de
KNX/IP uses multicast to represent group communication of the KNX bus over
IP. Always use a KNX/IP router from any manufacturer for connecting the
Gira G1 to a twisted pair (TP) bus.
Tip
Faster project planning with IP direct connection
In the "Communication" section of the ETS settings, select the "Use direct KNX-
IP connection if available" option to accelerate the transfer of the KNX project
from the ETS to the Gira G1.
Tip
Project planning using a WLAN connection
The multicast telegrams used by the KNX system can go astray during WLAN
operation.
If problems occur during WLAN operation with ETS programming via the routing
interface of the ETS, please try one of the following solutions:
- Establish a tunneling connection via the Gira KNX IP router (article no.
2167 00, from firmware version 3.0 onwards) and program the Gira G1.
- Establish a connection to the line/area "underneath" a Gira KNX IP router (arti-
cle no. 2167 00, from firmware version 3.0 onwards) and program the
Gira G1.
With either of these proposed solutions, activate the "Reliable communication"
function both on the KNX IP router and on the Gira G1.
