The bus is a wired-AND configuration where signals are sent by briefly shorting the bus to a low voltage level. This has the disadvantage that the network cable is required to be mains-rated, with V isolation, but has the advantage that it may be run next to mains cables or within a multi-core cable which includes mains power.

Also, mains-powered devices e. The network cable is required to provide a maximum drop of 2 volts along the cable. This also allows plenty of headroom for a bridge rectifier in each slave. Each bit is sent Manchester coded a "1" bit is low for the first half of the bit time, and high for the second, while "0" is the reverse , so that power is present for half of each bit time. When the bus is idle, it is high voltage all the time which is not the same as a data bit.

Frames begin with a "1" start bit , then 8 to 24 data bits in msbit-first order standard RS is lsbit-first , followed by a minimum two bit times of idle.

In addition to this method of control, DALI devices can be arranged into groups in which all devices of the same Group can interact with each other.

For example, a room with 4 ballasts can be changed from off to on in three common ways: Using the Short Address, e. The fade rate of the transition can be chosen on the fly.

This method can have an undesirable side effect called " Mexican Wave " when a single large room such as an auditorium contains many ballasts, due to network latency of the comparatively slow baud rate of DALI. For example, a transition from all on to all off may result in a visible delay between the first and last ballasts switching off.

This issue is normally not a problem in rooms with smaller numbers of ballasts. This method has the disadvantage of requiring each ballast to be programmed with the required group numbers and scene information, and has a fixed fade rate which is preset at the time of commissioning.

A value of is reserved for freezing the current lighting level without changing it. In a response, it indicates a lamp failure.

This is designed to match human eye sensitivity so that perceived brightness steps will have uniform brightness change, and to achieve a uniform brightness between units from different manufacturers.

For example, a room with 4 ballasts can be changed from off to on in three common ways:. This method has the advantage of not relying on the limited number of scenes available in each ballast, or having programmed each ballast with the required group numbers and scene information.

Digital Addressable Lighting Interface

This method has the disadvantage of requiring each ballast to be programmed with the required group numbers and scene information, and has a fixed fade rate which is preset at the time of commissioning.

DALI lighting levels are specified by an 8-bit value, where 0 means off, 1 means 0. A value of is reserved for freezing the current lighting level without changing it. In a response, it indicates a lamp failure. This is designed to match human eye sensitivity so that perceived brightness steps will have uniform brightness change, and to achieve a uniform brightness between units from different manufacturers.

Devices store 16 programmable output levels as "scenes". A single broadcast command causes each device to change to the configured level, e. A programmed output level of causes a device not to respond to a given scene. A 17th "system failure" scene is triggered by a loss of power sustained low level on the DALI bus, to provide a safe fallback if control is lost. DALI commands are 16 bits long, an address byte followed by a data byte.

The address byte specifies a target device or a special command addressed to all devices. When addressing a device, the least significant bit of the address byte specifies the interpretation of the data byte, with "0" meaning a lighting level byte follows, and "1" meaning a command follows. When sending a special command, the data byte is a parameter.

An important special command saves the data byte to a "data transfer register" which is then used as a parameter by subsequent addressed commands. Common commands specified by the DALI standard: A "DALI 2" extension adds support for "controls": On the Mesh Professional Lighting Subgroup was created as a forum to discuss and develop Bluetooth mesh technology as a foundation for the wireless lighting standard.
