The '''Digitally Adressable Lighting Interface''' ('''DALI''') is a digital [[Communications protocol|protocol]] for the controlling of [[lighting]] in buildings (e.g. [[Ballast (electrical)]], [[Dimmer]], etc.).

''' Digitally Adressable Lighting interface ''' (''' DALI ''') is digital protocol for the controlling of lighting in buildings (e.g. [[Ballast (electrical)]], [[Dimmer]], etc.). Each operating equipment, which has an DALI interface, can be communicated with over DALI individually. By a bi-directional data exchange a DALI controller can query and set the status of each light. DALI can be operated as “stand alone system” with maximum of 64 devices or be a subsystem via DALI gateways in modern [[building automation]] system. DALI was established as a successor for the still market dominating [[1-10v]] and [[Open standard]] rival to [[Digital Signal Interface|DSI]]. DALI is standardized in accordance with [[International Electrotechnical Commission]] 60929, standard for fluorescent lamp ballasts.

== Advantages ==

Each operating equipment with a DALI interface can be communicated with over DALI individually. Using a [[bi-directional]] data exchange, a DALI controller can query and set the status of each light. As a “stand alone system”, DALI can be operated with a maximum of 64 devices. Alternatively, DALI can be used as a subsystem via DALI gateways.

* Is it a open standard not exclusive to any company

== Advantages ==

* It only requires one wire for up to sixty-four devices.

DALI is an [[open standard]] not exclusively owned by a single company. It only requires one wire for up to 64 devices.

== Disadvantages ==

* Because each device shares the same wire, eachEach device gives itself a random number to identify itself, thiswhich makes inital installation and replacing faulty devices confusing as there is no indication which device is which, until you send out test signals and look to see which device responds. Being restricted to sixty-four addresses DALI cannot be used in large installations without using another technology to circumvent the limitation.
