Overview of network-capable devices via BUS
The gateway as well as the LuchsNT light control unit, Control NT and the converter box
have a standard BUS connection. This allows these devices to be connected to each other
with protection against polarity reversal. The gateway works as MASTER, the other
devices as SLAVE. An individual device address must be set on each SLAVE device.

During installation, terminals A are connected to each other and terminals B are connected
to each other.
For correct BUS operation, the BUS address must be set on the devices. Please note that
the BUS address is only adopted when the device is restarted. To do this, disconnect the
device from the mains and reconnect it.
