Product description Connectors, buttons and LEDs description
The KNX TP line coupler MECtp connects two TP lines as main line and
subline. MECtp can be used as KNX line coupler and KNX area coupler
or KNX repeater (without filtering). The lines have a galvanic separation
between each other. Operational and filtering states, malfunction and
faulty communication are indicated by LEDs.
MECtp is able to filter the traffic according to the installation place in
the bus system hierarchy and according to the built-in filter tables for
group oriented communication. Extended frames and long messages
with up to 240 bytes APDU length are supported. For commissioning
and troubleshooting a configurable Manual Function to temporarily
deactivate filtering is available. It can be activated by a single button
press and its switch-off after a pre-set time period is automatic
 Suppress device configuration from the subline

Enable/disable filtering of Group telegrams or Physical telegrams
 Number of repetitions is reducible
 Confirmations can be added to sent out telegrams
Requirements of Directives EMC, RoHS and LVD are met. Standards for
residential, commercial, and industrial environments are fulfilled. The
