DALI-2 versus DALI version-1

DALI-2 and interoperability

► DALI-2 certification brings the promise of significantly improved multi-vendor interoperability compared with the current DALI (version-1) systems in the market.

► Testing procedures for DALI-2 are much more detailed and comprehensive than for DALI version-1, and will be further improved if new issues are identified.

► DiiA organizes regular Plugfests, which are events to allow member companies to test interoperability of their products with those from other manufacturers.

► Plugfests also enable validation and further improvement of test sequences.
