TAPKO MECrf Operating Instructions

TECHNOLOGIES GMBH

Product description

The TP RF media coupler MECrf is a KNX RF Ready S-mode (RF1.R)
router for connecting KNX RF and KNX TP. MECrf can also be used as a
retransmitter. Operational and filtering states, malfunction and faulty
communication are indicated by LEDs.
MECrf 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. Long messages with up to 201 bytes APDU
length are supported. For commissioning and trouble-shooting 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. Further functions:
• 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 RED and RoHS are met. Standards for
residential, commercial, and industrial environments are fulfilled.
Hereby, TAPKO Technologies GmbH declares that the radio equipment
type MECrf is in compliance with Directive 2014/53/EU.
