MECtp-SEC Line Coupler connects two TP KNX lines 

Due to its flexibility MECtp-SEC can be used as a linecoupler, area coupler or backbone coupler to connect subline and main line in secure mode.

Here, MECtp-SEC filters the traffic according to the installation place in the hierarchy (Physical telegrams) and according to the built in filter tables for group oriented communication (Group telegrams). 

Used as a line repeater, MECtp-SEC is able to link two TP lines only for data transfer. 

In this way, MECtp-SEC can form a single line with up to three additional segments. 

Each line segment requires its own KNX power supply.

MECtp-SEC provides outstanding features, for example its support of long messages (up to 240 byte APDU length) and a configurable "Manual Function" (transmit all telegrams, transmit all Physical telegrams, transmit all Group telegrams) with single button press activation and automatic switch-off. 

This functionality is helpful during commissioning, during run time and for trouble shooting. 

The ability to temporarily disable the telegram filtering by only pressing a button allows access to other lines without additional download from the ETS and reduces the telegram traffic to make debugging and commissioning easier.

Specifications & Special Features:

• Can be used as line/backbone coupler and line repeater
• Galvanic isolated data connection between two separate KNX bus lines
• Can be used with ETS4.0 and higher
• Support of long telegrams (max. 240 bytes APDU)
• Configurable IACK sending on TP telegrams for data throughput increase
• Reduced number of retransmissions
• Ability to suppress configurations from subline to main line (during full access from main line to subline)
• Ability to temporarily disable the filtering of messages by pressing a button. This reduces the bus load to make commissioning and debugging easier.
• Temporary access to other lines is possible without an additional ETS download
• Bus status (traffic, errors, routing) of each line are shown by duo LEDs
• Many functions (filtering, tracing, blocking, ...) available
• Trace the subline traffic
• Enable/disable filtering of Group telegrams or Physical telegrams
• Suppress device oriented telegrams
• Eased network diagnosis
• Configurable one-button activation of special functions
• Installation module for 35mm top-hat rails (DIN, TH35)
