The KNX/EIB/TP1 bus terminal 753-646 is used to connect to a KNX/EIB/TP1 network. The terminal supports two different functions:

1. Device Mode: The terminal allows the connection of programmable controllers relevant to building automation to a KNX/TP1 network. In a KNX network, the terminal appears as a standard KNX device and is integrated using the commissioning tool ETS Professional. The terminal supports a maximum of 253 communication objects with any DPTs, 254 group addresses, and 254 associations. The application programming is done via the WAGO-I/O-PRO CAA software. The assignment of data from the application program to group addresses is done through an ETS plug-in, which is included in the WAGO product database.

2. Router Mode: When combined with the KNX IP controller 750-849 or 750-889 and the first connected KNX/EIB/TP1 terminal 753-646, the device becomes a KNXnet/IP router. The switch to router mode occurs automatically. An application program is not required for operation in router mode. Additional terminals connected to the KNX IP controller are addressed by the application in device mode.

The plug of the 753 series with internally bridged contacts (3/7 and 4/8) is included in the delivery.

An external KNX power supply and ETS Professional are required for the operation of the KNX/EIB/TP1 bus terminal.
