Hello @Giamba , i was trying to use your dimmer program to to get a 0-10v output on my M203. I'm pretty sure i excactly copied your programm but not the results as you descripe. First of all, it will anly switch between 0 an 10V. no dimming function. Second problem is that i cannot connect the eq_0 / in1 to the BD30 counter to the br. Wont accept. maybe i made a misgtake but i cannot get it. Is it also possible to send me the parameters you use for the components in your programm? Many regards John-paul
