Gira S1 Windows client
10.3.1. Accessing a KNX installation via KNX/IP
Figure 20: KNX/IP remote access configuration
The configuration for secure KNX/IP remote access comprises three options:
KNX/IP remote access
KNX/IP access can generally be deactivated, if you only need to quickly access a computer via Remote
Desktop and do not need KNX/IP, for example.
Always use Gira S1 only for KNX access
If desired, you can also make only the tunnelling server of the Gira S1 accessible via remote access,
e.g. because many devices are available on the remote network and you are in a hurry.
Prefix for exposed KNX/IP devices
If KNX/IP access is permitted, all KNX/IP tunnelling servers and KNX/IP devices found on the remote
network which support fast IP download (see ETS options) are reported on the computer with the ETS
by default so that they appear in the Connection Manager of the ETS. (Observe the note below on the
user of ETS4 versions older than ETS4.2). To see at a glance which devices are connected via remote
access, you can enter a prefix of your choice up to eight characters in length.
Important note:
When using ETS4 versions older than ETS4.2, problems may occur during automatic detection of the
KNX/IP interfaces in the ETS4, which mean that they do not appear. In this case, you must configure
the interfaces manually in the ETS4.
To do so, manually create a new connection in the ETS4, assign a name of your choice and copy the
corresponding IP address and port from the Gira S1 Windows client to the input fields in the ETS4.
The Gira S1 Windows client provides assistance here if a connection is open by offering buttons for
copying the corresponding values to the clipboard.
Refer to the figure below for this.
