KNX TP lines/areas. KNX TP main line and KNX TP subline are coupled having a galvanic isolation in between. Using the TP Coupler application, ITR901-0002 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 a TP Backbone.
KNX Line Coupler Product Manual 1.2. LED Indication If ITR901-0002 is used as Line Couper without physical address x.y.0, LED 6 (PA) that is showed at table 1, works not like described here. NUMBER COLOUR DESCRIPTION Green Main Line OK.
ACK sending on sent out messages is ETS configurable. ➢ When there is no IACK response on the subline the Interra KNX IP Router is able to repeat messages up to three ➢ times. Repetitions can be configured for both Physical Telegrams and Group Telegrams via ETS (to ease troubleshooting).
ITR901-0002’s ETS database entries are available for ETS4 and later. ➢ 2. Operational Description In network installations ITR901-0002 can be used as KNX TP area/line coupler or KNX TP line repeater. With its default settings, device operates as is supposed to. 2.1. TP Coupler Application...
Under the Information tab the configuration setting can be changed by the drop-down menu “Change Application Program”. After changing the configuration setting the filter table entries can be added manually. Updating the application program can also be done here.

ITR901-0002 has to use the correct Physical Address of an area coupler (X.0.0, 1≤X≤15). In ETS up to 15 areas can be defined. If ITR901-0002 is used in a KNX system for both purposes, it is only necessary to ensure that the ITR901- 0002 used as a line coupler has a line coupler address assigned from a free addressing area.
Note: Using repeaters on the backbone or on the main line is not allowed. Fig 6 : Network Topology The free tree structure of the KNX topology prevents problems caused by circling telegrams and heavy bus load. So, interconnection between lines is strictly forbidden. @2022 INTERRA PM220621013CEN...
15.15.0. The KNX product database entry (available for ETS4 and higher) can be downloaded from the Interra website and from the KNX Online Catalog. With the ETS the physical address can be assigned to the device by setting the desired address in the properties window of the ETS. After starting the ETS download and then pressing the Program Button the device restarts itself.
During normal operation a rather short press (≈ 3 sec) activates the Manual Function. When the Manual Function is active, either all Physical Telegrams or all Group Telegrams or both pass the ITR901-0002 without filtering. After the Switch-off time period has elapsed ITR901-0002 automatically switches back to normal operation. To configure the Manual Function and set the Switch-off time use the General parameter tab like shown in chapters 3.1 and 4.1.
Physical address telegrams pass all Groups address telegrams Switch-off time for After expiry of this period the Manual Function is 10 mins, 1 hour, 4 hours, 8 hours Manual Function switched off automatically. @2022 INTERRA PM220621013CEN...
For Group Telegrams and Physical Telegrams, the setting “transmit all” is intended only for testing purposes. Please do not use for normal operation. Note: If the parameter “Send confirmation on own telegrams” is set to “yes”, the ITR901-0002 systematically sends an ACK on any own routed telegram.

For Group Telegrams and Physical Telegrams, the setting “transmit all” is intended only for testing purposes. Please do not use for normal operation. In addition, if the parameter “Send confirmation on own telegrams” is set to “yes”, the ITR901-0002 systematically sends an ACK on any own routed telegram. Since the repeater does not use a filter table, it is useful to have an ACK sent along with routed telegrams.
