The Gira KNX RF/TP Media Coupler or Repeater (5110 00) is associated with connecting or extending communication between KNX radio-frequency (RF) and twisted-pair (TP) parts of a building automation system, depending on the exact product variant and application. Such devices can help integrate RF components with a wired KNX installation or support RF network coverage where the specified mode permits. The article number and variant must be confirmed carefully before design because media-coupler and repeater functions are not interchangeable in every configuration. Check the current Gira datasheet and ETS application for supported modes, topology rules, RF compatibility, power requirements and commissioning steps before including it in a project.
