KNX module installation and activation

File:CM5-drawing-3D-angle-KNX.jpg Physical connection of CoolMasterNet to KNX bus (TP physical layer) is made with "CoolAutomation KNX extension module", further referenced as KNX module. KNX module can be pre-installed inside CoolMasterNet body by CoolAutomation or can be purchased later and installed by customer itself. Once KNX module is installed it should be activated on line L3. Run line command to check if KNX module is already activated.

The trace above corresponds to the activated KNX module. Otherwise special activation string should be provided. To get activation string contact CoolAutomation and specify a serial number of the CoolMasterNet device where KNX module has to be activated. Once activation string is provided by CoolAutomation it should be entered as a regular command.

Now KNX module is ready for operation and can be connected to KNX bus. Mind the polarity - it is essential for KNX bus.

Group Addresses concept

The communication between KNX devices is made with telegrams sent to Group addresses. A Group address is a logical name for a given topic linking the output of a sensor with the input of an actuator.
