GVS K-BUS KNX/EIB IP/KNX Convertor ○ 1. Summary The IP/ KNX convertor is designed for an intelligent building control system, which is used to connect the KNX bus and the LAN. It serves as an interface between KNX installations and IP networks. TCP telegrams from the client devices on the LAN can be converted to KNX telegrams via the convertor, and be sent to the KNX bus to control KNX devices.
GVS K-BUS KNX/EIB IP/KNX Convertor ○ The IP/KNX convertor is able to use the Engineering Tool Software ETS (ETS3 or later) which can import a VD4 files to allocate the physical address and set the parameters. 2. Technical Properties, Dimension and Circuit Diagram 2.1 Technical data...

GVS K-BUS KNX/EIB IP/KNX Convertor ○ 3. Project design and application 3.1 Overview of the functions Open communication protocols The communication protocols for IP Interface is open, anyone can follow the text of the protocols to achieve communication between the IP network devices and KNX devices via IP/KNX Converter. So you can easy to connect the KNX/EIB bus system with the IP network into a whole, and ensure the reliability, commonality and scalability of the system internal real-time communication, and really realize the openness of the system.
GVS K-BUS KNX/EIB IP/KNX Convertor ○ Reading and writing data type The data telegram that the length is less than or equal to14bytes can be sent to or read from the EIB bus via the IP/KNX convertor. The data which is read from the EIB bus is only forwarded to the client of the read request initiated.
GVS K-BUS KNX/EIB IP/KNX Convertor ○ Fig.3.2 parameter window “IP settings” Parameter “Device name (Max. 30 Char.)” This parameter defines the name of the IP convertor to identify the device on the LAN. Here can entry a maximum of 30 characters in length. It is a spare parameter in current version.
