![]() The DALI data is transmitted using manchester encoding and has a high signal to noise ratio which enables reliable communications in the presence of a large amount of electrical noise. The DALI System is not classified as SELV (Separated Extra Low Voltage) and therefore may be run next to the mains cables or within a multi-core cable that includes mains power. The network can be arranged in a bus or star topology, or a combination of these. Data is transferred between controller and devices by means of an asynchronous, half-duplex, serial protocol over a two-wire differential bus, with a fixed data transfer rate of 1200 bit/s.ĭALI requires a single pair of wires to form the bus for communication to all devices on a single DALI network. ![]() Alternatively, DALI can be used as a subsystem via DALI gateways to address more than 64 devices. The DALI protocol permits devices to be individually addressed and it also incorporates Group and Scene broadcast messages to simultaneously address multiple devices (e.g., “Group 1 goto 100%” or “Recall Scene 1”).Įach lighting device is assigned a unique static address in the numeric range 0 to 63, making possible up to 64 devices in a standalone system. The controller can monitor and control each light by means of a bi-directional data exchange. Non AG DALI members can apply for a fee bearing licence.Ī DALI network consists of a controller and one or more lighting devices (e.g., electrical ballasts and dimmers) that have DALI interfaces. Members of the AG DALI are allowed to use the Digital Addressable Lighting Interface (DALI) trademark on devices that are compliant with the current standard. IEC 60929 is the first version of the standard and will be withdrawn by 23rd of June 2014. They were established as a successor for 0-10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is based. IEC 60929 and IEC 62386 are technical standards for network-based systems that control lighting in buildings.
