I am sending toggling Direct arc power commands to a LED driver. ( OFF / ON ) at an equal interval of 500mS. I am monitoring the dali bus commands with a Lunatone USB interface and I can see that the Led driver sometimes missed the ON - interestingly it never missed the off command. The interval between commands was then extended to 1500mS. This then showed that there it was not missing the command but in fact a notable delay happening occasionaly with the ON command.
There is only the one Dali device on the bus. I'm wondering what the specification is for this.
Edit: Looking at the Dali Specification ( Standards titles ONLY ) What is the difference between : 1) BS EN 62386-102:2014 CONTROL GEAR 2) BS EN 62386-103:2014 CONTROL DEVICES
(one wonders why they would not be in the same standard as probably much is duplicated)
