2.5.2 DALI topology
The DALI ECGs are wired in parallel to each other and groups are not
taken into consideration. Star configurations are also possible. Ring
wiring is not permitted (indicated by X in the diagram). There is also no
need for terminating resistors on the communication cable.

2.5.3 DALI parameters in the ECG
The following data can be stored in the DALI ECGs when a DALI
system is started up:
• Group assignment of the DALI ECG (max. 16 groups, multiple
assignment is possible)
• Individual address for accessing each ECG directly (max. 64)
• Lighting values for the individual scenes (max. 16)
• ECG parameters that determine the behavior of the ECG:
• • Dimming rate
• • Behavior if the voltage fails on the interface (System Failure Level)
• • Behavior when the mains voltage is restored (Power On Level)
In addition to the above-mentioned options, it is always possible to
address all the devices together, even without programming the de-
vices beforehand (construction site function).
