Most modern computers, especially laptops, do not provide a serial port, rather they have a USB (Universal Serial Bus) socket.
For existing EIB-RS232 interfaces, the Weinzierl EIB/KNX-USB adapter for RS232 allows you to connect to an EIB installation over USB, thus avoiding the need to change existing interfaces in future. The adapter can be plugged into an existing RS232 interface on a DIN rail.
The EIB/KNX-USB adapter for RS232 is compatible with ETS3 or later.
