KNX RS-485 Gateway Platform 88X

The KNX RS-485 Gateway Platform 88X is used to connect devices with RS-485 Interface to KNX bus. Since no standard RS-485 protocol is defined, the application must be created specifically for the necessary requirements. This includes the implementation of the corresponding telegram format for RS-485 and the definition of the required group objects on the KNX side. For this, an individual database for the ETS can be created.

The KNX RS-485 Gateway Platform 88X is especially suitable to develop OEM products. For the individual connection of your system, please contact Weinzierl Engineering.
