1.) PRODUCT DESCRIPTION
The ITR901-001 Interra KNX IP Router works as a KNX line/area coupler to provide a bi-directional data connection between
KNXnet/IP line (main line) and KNX TP line (subline). KNX IP and KNX TP are coupled having a galvanic isolation in
between. The flexible ITR901-001 can be used as a KNX TP line coupler to connect several KNX TP lines but also as a KNX
TP area coupler to connect several TP areas or different KNX TP installation systems via an IP Backbone/Ethernet/Internet.
Telegram filtering is accomplished according to the installation place in the hierarchy (Physical Telegrams) and according
to the built in filter tables for group communication (Group Telegrams). For detailed diagnosis all operational modes/states
are shown by a duo-LED display.
With the ETS (or compatible commissioning tool) ITR901-001 also works as the KNX programming interface having no
KNX communication objects for itself. Connecting a personal computer to the KNX TP bus can ideally be done via
Ethernet/Internet. For Tunnelling and Routing up to four tunnelling addresses can be used. To ease commissioning and
troubleshooting the Manual Function for short-time telegram filter switch-off and special routing/repetition/confirmation
settings are available. A comfortable Web front-end to watch the busload history, to identify ITR901-001device in a
network and to update the firmware via IP is provided.
