In the data interface catalog (see also catalog: Interface Media Gateway), you will find interfaces for connection to building automation systems. Data interfaces are available in different versions, depending on the data protocol e.g. USB, RS232, RS585, IP routing, IP tunneling. KNX data interfaces, except the ones for flush-mounted installation, are usually equipped with integrated bus coupler and permit the connection of a PC to the KNX system for addressing, programming and diagnosis of KNX devices. For commissioning and diagnostic functions, the ETS requires (Engineering Tool Software) a connection to the KNX bus system. This is usually achieved with a KNX USB interface or an IP interface. If the network installation has WLAN, wireless access from a laptop can be provided. By means of KNX data interfaces, any third-party systems (heating, ventilation, air conditioning etc.) can be integrated and data can be exchanged.
