The „EIBWeiche“ device in combination with the MS-Windows software „EIBDoktor“ is an easy-to-use but powerful installation tool you should not miss while doing your EIB/KNX installations. The software shows each bus telegram, even disturbances on the bus are geng displayed. Function keys F1-F12 can be programmed with any EIB/KNX telegrams to simulate missing EIB/KNX sensors, so you can easily test your EIB/KNX-installation. Powerful statistics are helpful to fi nd bottlenecks in big installations, and device failures can be found by a simple mouse click. The serial RS-232 version of the EIBWeiche works with all Windows versions. The USB version requires Windows XP or newer. The power for the EIBWeiche is supplied directly from the PC, so the EIBWeiche needs no main plug. The EIBWeiche devices can also be used for programming with ETS. ETS2 - ETS5 databases are supported to import data type informations and to display the ETS address comments.
