Appendix B. DALI Networking Basics
DALI is very flexible in its network configuration, to the point that DALI control lines and mains voltage
supply lines can be wired together.
The DALI control line input to a ballast is polarity insensitive, meaning there is no + or -.
A DALI network can consist of up to 64 ballasts.
Wiring of the DALI network can be almost any fashion, be it a daisy chain, star or branch, as per the below
figure
Figure 2 DALI Network Topologies
