Collisions between several DALI masters on the DALI bus are solved on the basis of timing

priorities. When a collision is detected (the DALI master should check the sent data),

communication is muted for a period of time according to the assigned master priority. There

are five defined priority levels: 12 ms, 13 ms, 14 ms, 15 ms, and 16 ms. The longest waiting

time has less priority.
