Have we got any DALI experts on this forum?

I am trying to connect a serial → DALI converter to the Vera but am having trouble understanding one section of the DALI spec and that is what commands are required to do the initial commissioning phase.

Currently I can send a broadcast command to turn lights on and off but need to set short addresses and have hit a dead end in trying to dig up the actual DALI command sequences to do this.

Any help appreciated.

Short addresses on DALI range from 0-63. You should be able to query a node for its short address and then verify it. Another way around it would be to program the short addresses manually.

Wish it was that simple.

I don’t have a problem with the addressing it is more a problem of commissioning.

e.g.
What is the result of an initialise command?
What do you do after you issue a randomise command?
How do you find the short addresses that have been assigned by the randomise command?

My understanding is that initially DALI slaves come without a short address and this needs to be added.

Any idea of which processor your slave nodes are using? Most of the semiconductor companies such as ST, Atmel, Renesas have application notes that you should be able to follow.

Yes, I think I have progressed a little further I am going to do some experimenting and see what happens.

Thanks
