Page 3: Introduction
1 Introduction This manual describes the functions of the KNX field/line coupler (GW 90708A) device and how they are set and configured with the aid of the ETS configuration software. The GW90708A device has two separate ETS application programmes based on the function to be performed: KNX Line coupler S 1.0 - Coupler... -
Page 4: Application
2 Application The KNX field line coupler (from DIN rail) is used to connect a main KNX-TP line with a secondary KNX-TP line, providing galvanic insulation between the two. The device filters the traffic between the two lines (coupler) or forwards packs from the main line to the secondary one (repeater). -

7. Manual function key Press the button key for at least 3 seconds to activate the manual function (defined by the ETS parameter in the menu). The green and red main line status LEDs (1) turn on to indicate activation of the function. -

2.2 Repeater Line repeater (RP) Physical address X.Y.Z. Transmission and repetition of telegrams on a line without a filter. Division of a line into max. 4 independent line segments with max. 3 repeaters connected in parallel for each line. Each line segment requires its own KNX power supply (PS). -

3 "General" Menu (Coupler) The General menu contains the parameters used to define the manual function of the local button key. The basic structure of the menu is as follows: Fig. 3.1 3.1 Parameters 3.1.1 Fallback time for manual operation The manual function activated by the device's local button key can be deactivated by pressing the button key or automatically after the preset time defined via the parameter “Fallback time for manual operation”... -

4 "Main line" menu (Coupler) The Main line menu contains the parameters used to define the rules for forwarding telegrams from the main line to the sub line. The basic structure of the menu is as follows: Fig. 4.1 4.1 Parameters ... - Page 9 4.1.3 Main group telegrams 14/15 This parameter is used to define the rule for forwarding telegrams whose recipient has a group and main group address 14 or 15 (e.g. 14/x/x, 15/x/x); The values that can be set are: transmit all (default value) all telegrams are forwarded block...
- Page 10 4.1.7 Telegram confirmations on main line This parameter defines the rule for confirming telegrams (ACK) transmitted on the main line. The values that can be set are: if routed (default value) the device sends the confirmation telegram for only the telegrams transmitted on the main line that are forwarded on the sub line always the device sends the confirmation telegram for all telegrams on the main line, regardless if they are...

5 "Sub line" Menu (Coupler) The Sub line menu contains the parameters used to define the rules for forwarding telegrams from the sub line to the main line. The basic structure of the menu is as follows: Fig. 5.1 5.1 Parameters ... - Page 12 5.1.2 Group telegrams This parameter is used to define the rule for forwarding telegrams whose recipient has a group and main group address between 0 and 13 (e.g. 0/x/x, 1/x/x … 13/x/x); The values that can be set are: transmit all (for testing only) all telegrams are forwarded block...
- Page 13 5.1.6 Group: Repetition if errors on sub line This parameter is used to enable the repetition of telegrams generated by the coupler if there is a transmission error on the sub line (e.g. due to a receiver failure); in particular, this parameter refers to telegrams whose recipient has a group address.

7 "Main line" menu (Repeater) The Main line menu contains the parameters used to define the rules for forwarding telegrams from the main line to the sub line. The basic structure of the menu is as follows: Fig. 7.1 7.1 Parameters ... - Page 16 7.1.3 Physical: Repetition if errors on main line This parameter is used to enable the repetition of telegrams generated by the repeater if there is a transmission error on the main line (e.g. due to a receiver failure); in particular, this parameter refers to telegrams whose recipient has a physical address.

8 "Sub line" menu (Repeater) The Sub line menu contains the parameters used to define the rules for forwarding telegrams from the sub line to the main line. The basic structure of the menu is as follows: Fig. 8.1 8.1 Parameters ... - Page 18 8.1.3 Physical: Repetition if errors on sub line This parameter is used to enable the repetition of telegrams generated by the repeater if there is a transmission error on the sub line (e.g. due to a receiver failure); in particular, this parameter refers to telegrams whose recipient has a physical address.
