Line coupler MECrf connects a KNX-TP-main line with a KNX-RF-sub line.

Main task of the MECrf is filtering the telegram traffic according to the installation place in the hierarchy  or according to the built in filter tables for group oriented communication. Filtering of messages can be enabled or disabled.
With the MECrf it is possible to address every bus device in the bus system.
For RF devices the MECrf can be used as the programming interface via TP. Programming on the TP side from RF side can be suppressed.


Features / Benefits

  • blocking configuration attempts from RF side in to TP side and fully transparent access for configuration from TP side towards RF side
  • Number of retransmissions can be reduced. Device oriented messages can be suppressed.
