Product description
Connectors, buttons and LEDs description
The TP RF media coupler MECrf is a KNX RF Ready S-mode (RF1.R) router for
connecting KNX RF line and KNX TP line, or more exact, for connecting KNX RF
devices to the TP installation. MECrf can establish direct connections to RF
devices, and 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 are supported.
Configuring from subline can be deactivated. Special functions for transmission
of telegrams are available. Filtering can be temporarily deactivated on pressing
the Function button (Manual Function), i.e. to ease commissioning. It can be
activated by a single button press on the device. MECrf then automatically
switches back to normal operation after a configurable time period.
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.
