I have been testing with a few leds but it did not seem to work. Also shining a bright led torch on the Q200 did not make any difference. So, I ordered a couple of bright white SMD leds and some SFH320 optotransistors. Following the image on the PCB I mounted the led, which did not lit up. It seems it has to go the other way. Installing the SFH320 did pass the torch-test so it reacted. The setup needed some adjustment, perhaps due to the different characteristics of the Q200 optotransistor but I did get it to work.
