Yes, there is in our catalogue the GIOVE SERVERKNX interface, to be connected via serial port to the CA20_CA21 controllers on one side , and on the other side directly to the KNX bus by in/out screw connector for easy insertion in any position. The interface is configured by means of simple web pages, connecting via lan from each PC. It is possible to decide how many and which functions of the Giove system to manage via KNX, freely assigning addresses of the preselected groups (in the format XX/YY/ZZ).
