MECtp Line Coupler connects two TP lines

Due to its flexibility MECtp can be used as a linecoupler, area coupler or backbone coupler to connect subline and main line. Here, MECtp 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 is able to link two TP lines only for data transfer. In this way, MECtp can form a single line with up to three additional segments. Each line segment requires its own KNX power supply. MECtp 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 ETS3.0d 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)
