General
The Digital Addressable Lighting Interface (DALI) makes it possible,
by using a bidirectional, serial, asynchronous data protocol, to control
lighting control gear (electronic ballasts, power dimmers, LEDs, etc.) The
control line can be installed using almost any network topology and has
a maximum cable length of 300 m. This makes it possible to implement
even complex lighting topologies without undue effort, especially since
the two-core control line can be laid together with the supply line in a
single cable (e.g. NYM 5 x 1.5 mm²).
Our DALI gateways make it possible to operate up to 64 DALI electronic
ballasts on a single bus and these can be grouped together into up to
16 groups. Up to 16 storable lighting scenes make adjustments possible
that cater for various lighting requirements in the planned application
area�
Individual lighting groups can be dimmed between adjustable minimum
and maximum values with configurable dimming speeds that can be
separately set for each individual lighting group. Holding the dimming
key down brightens and dims lighting cyclically with a one-second pause
each time the brightening/dimming direction changes. Briefly pressing
the key for a lighting group switches the lighting off or, if pressed again,
the lighting is switched on to the previous dimming level (value stored in
the memory). The value in the memory is lost if the power supply fails.
This brightness change takes place at a separately configurable fading
speed. This speed is also used to set central commands and the saved
brightness levels of lighting scenes.

Usage and safety
The DCI 4 DALI was developed for open-loop control of control gear on
a DALI lighting control bus. The unit switches the bus devices at brief
intervals during configuration. You must therefore check in advance that
