Hi Carolin, thanks for the advice. I think I know how to set up in the PC-software.

Another query is that I read from a number of post that if the lights are controlled using 1-10V-interfaces than the power plugs of the light can be connected to live sockets direct. However, for my light, as mentioned above, the light will be on when I plug the corresponding power plugs to live sockets (seemed should be off). Is it normal for the dimmable light fixtures you encountered? Also, am I correct that there should be a fixed physical mapping between each of the two GHL plugs with the 3 dimmable light pairs (i.e. 1 GHL plug will dim 1 pairs and the other dim other 2 pairs) which I should test out first?

Thanks!
