The EITT tool is the KNX Interworking Test Tool for putting KNX devices through their paces.
EITT is a special analysis tool for KNX devices and installations. It is primarily used by manufacturers and test laboratories for testing, troubleshooting and monitoring the Interworking and system stack compliance of KNX products. EITT is also a powerful tool for the analysis and simulation of the KNX device network protocol.
The EITT supports test through multiple interfaces at the same time. KNX telegrams are recorded online and can be analysed via a multitude of filter criteria. Various trigger functions are available. In addition the EITT can send telegram sequences for simulation and test purposes. States like ACK, NAK, BUSY or Flags are shown in the bus monitor.
