1 INTRODUCTION 1.1 LINECOUPLER CL Linecoupler CL is the KNX line-coupling and line-repeating solution from Zennio. This device is intended to couple two KNX twisted-pair lines together. Its flexibility makes it possible to connect a KNX line to a KNX mainline or a KNX mainline to a KNX backbone line (line coupler mode), or to simply link together two line segments (line repeater mode).

Linecoupler CL Customizable Pushbutton for triggering the manual mode, useful at runtime and for set-up and troubleshooting purposes. 6 Lighting Indicators (LEDs) for accurately showing the bus status of each line, making the detection of abnormal situations (excessive bus load, message retransmissions, etc.) easier.
Note: each line (or line segment) being coupled requires a dedicated power supply. No power pass from one line to another is performed. The programming button (10) shown in Figure 2 may be pressed to set Linecoupler CL in programming mode. After a short press, the programming LED will light in red.
2 CONFIGURATION 2.1 GENERAL CONFIGURATION Linecoupler CL can be used as a line coupler (for coupling both a line to a mainline, or a mainline to a backbone line; the latter is normally referred to as “backbone coupler”) or as a repeater (for coupling two line segments). A different application program is provided for each purpose.

Linecoupler CL Regarding telegram filtering, the line coupler implements two complementary (and optional) filters: Group address filtering: ETS automatically generates a group address table for the project loaded. This table is transferred to the line coupler during application program downloads. When a telegram containing a group address in the “destination address”...

Linecoupler CL Physical address filtering: when the line coupler receives a telegram where the destination address is a physical/individual address (for example, during downloads), it will compare such address with its own physical address (no particular filter table is required for physical address filtering, but a simple comparison).

Linecoupler CL Mainline Status LED: shows the status of the primary bus. ➢ OFF = error: mainline not connected or not powered ➢ ON (green) = OK. ➢ ON (orange) = manual function in execution. Line Bus Status LED: shows the status of the secondary bus.
(one of which with no other connection to the installation, in order to prevent forbidden situations such as in Figure 6), both containing devices, need to be linked for extending the line. Linecoupler CL offers such linking interface, with proper electrical insulation for the connections.
2.2 MANUAL FUNCTION BUTTON Linecoupler CL features an additional pushbutton on the top cover, next to the status LEDs (see (4) in Figure 2), which permits: Activating the Manual Operation Mode (see section 2.2.1).
Linecoupler CL Pass all telegrams, Pass physical telegrams Pass group telegrams. Please refer to sections 3.2 and 4.2 for the parameterisation in ETS of the manual function and for a detailed description of the different options. 2.2.2 HARD RESET TO FACTORY DEFAULTS The manual function button permits performing a hard reset of the device, which will set it back to the factory default state, including the initial individual address.
3.1 DEFAULT PARAMETERISATION When entering the parameter edition of Linecoupler CL for the first time, a window similar to Figure 8 will be shown, where three main tabs are available: General, Main line and Line. Note that this application program does not implement communication objects.
Linecoupler CL 3.2 GENERAL As shown in Figure 8, this screen contains two parameters, both related to the manual mode of the device (see section 2.2): Manual Function: sets the desired function to be executed by the device while in the manual mode. The available values are: ➢...
This screen permits parameterising the behaviour of the line coupler regarding the mainline, that is, when the telegrams are received from the mainline. Figure 9 Mainline – Linecoupler CL The available parameters are described next: Configuration: permits selecting a general preset for the mainline, or enabling the manual configuration of each parameter (option “Custom”):...

Linecoupler CL ➢ Block: all telegrams will be dropped ➢ Filter: telegrams will be filtered, dropping only the corresponding ones, according to the filter table; see section 2.1.1. Group Addresses Telegrams > 13 [Transmit all (not recommended) / Block / Filter]: sets whether telegrams destined to a group address in groups from 14 to 31 (e.g., 17/1/1) will be dropped or transmitted.
/ Disable]: offers the possibility of disabling the download from the line to a device located in the main line. Figure 10 Line – Linecoupler CL Please refer to section 3.3 for a detailed description of these parameters, taking into account that section 3.3 applies to the mainline instead of the line.
4.1 DEFAULT PARAMETERISATION When entering the parameter edition of Linecoupler CL for the first time, a window similar to Figure 12 will be shown, where three main tabs are available: General, Main line and Line. Note that this application program does not implement communication objects.
Linecoupler CL 4.2 GENERAL As shown in Figure 12, this screen contains two parameters, both related to the manual mode of the device (see section 2.2): Manual Function: sets the desired function to be executed by the device while in the manual mode. The available values are: ➢...

Linecoupler CL Figure 13 Mainline – Linerepeater CL The available parameters are described next: Configuration: as in the Linecoupler application program, this parameter makes selecting a predefined scheme possible for the mainline, or enabling the manual configuration of each parameter (option “Custom”). However, the only available preset in the Linerepeater application program is: ➢...
Linecoupler CL Group Addresses: Repetition if Errors on Main Line [No / Normal / Reduced]: sets the desired reaction upon transmission errors in the mainline (e.g.: busy receiver, acknowledgement received, negative acknowledgement, etc.) of telegrams destined to a group address.
