Hi Greg, I am going to order this ( http://www.hasseb.fi/shop2/index.php?route=product/product&product_id=50 ) USB Dali-2 Master unit to start playing and getting familiar with DALI commands. With this unit I will be able to test our own slave hardware - software as well. I will share my experiments of course. Unfortunately this is not my main occupation, I am doing in my spare time, therefore may go slow.
