Short addresses, from 1 to 63, are assigned uniquely at random to every DALI device
when programming is first begun. These addresses are not assigned by the programmer.
Once all the devices have been discovered the the programmer will assign devices into
groups, from 1 to 16, according to the needs of the area with DIGIDIM Toolbox software.
For example, the power circuits on the relay unit have short addresses
5,6,7 and 8 but they have all been included in Group 3. Similary all
the lighting circuits, which have addresses 1,2,3 and 4, have been
placed in Group 1. Finally, the two circuits of wall lighting at
addresses 1 and 4 have been placed in Group 2.
