• DALI is a control protocol for controlling digital lighting equipment in buildings (e.g.
• Each operating device that has a DALI interface can be individually controlled via DALI short addresses.
• DALI uses a serial, asynchronous data protocol with a transfer rate of 1200 bps.
• Control cable is galvanically isolated and polarity-free (reverse polarity protected).
• the cables can be laid in almost any topology, ie star, line or tree structures. However, an annular connection of components should be avoided.
• the cable length between two system users is limited to a maximum of 300 meters (depending on the cable cross-section). There are not any
