The abnormal conditions and the corresponding treatment methods:
Digital Addressable lighting Interface (DALI)
DALI slave unit will send data only master unit requests, that is, adopt command answering mode
There are 64 slave units at most in the same DALI network, each unit has a separate address(short address), A salve unit can also be assigned to a certain group, and a slave unit can belong to different group, salve unit can exist up to 16 groups at the same time, each unit can set 16 scenarios.
The main features of the DALI protocol
1)Asynchronous serial communication.
2)1200 baud rate, using the Manchester encoding format.
3)Two lies differential signal.
4)The high level when differential voltage is larger than 9.5V.
5)The low level when differential voltage is less than 6.5V.
6)The master unit controls communication process.
7)One DALI bus can connect with 64 slave units.
8)Each slave unit can be individually addressed.
DALI Electrical Specification
Under the idle state, from machine unit method to control the bus：
1)High Output power at ordinary time, not to interference in the hold signal.
2)Output low electricity at ordinary time, directly to the DALI bus short circuit to each other.
3)DALI bus maximum current of 250mA
4)Not a two-way communication at the same time.
5)Transmission cable up to 300 meters, or pressure drop is no more than 2v
