The KNX-Interface LKNX-300 allows the LINX Automation Servers, the LROC-102 Room Controller, and the LGATE-95x Universal Gateways to interface to KNX devices connected to a KNX TP1 Bus. The LKNX-300 Interface needs to be connected to the EXT-Port on the L-INX/L-ROC/L-GATE devices.

For the KNX integration, L-INX / L-ROC / L-GATE devices use an ETS4 project. The project data is exported from the ETS4 software and then imported in the LINX-Configurator. Thus, up to 1 000 data points from the KNX network can be used by the L-INX /‌ L-ROC /‌ L-GATE devices on each port supporting KNXnet /‌ IP or KNX TP1.
