I'd never noticed it before with other controllers, but when connected to one of RJ's MR16 (16 channel DC) controllers, there is a very short timeout before it starts flashing. Is that the Keep Alive setting? and can I increase it? and do I want to increase it? I'm just using test software, not a sequencer, to drive the lights. When I move the slider, it is perfect. Nice smooth fades. But when I stop, 0.5 seconds later it starts flashing. Move the slider and keep moving it, and it is fine. Using a ENTTEC Pro or Lynx dongle does not do this. I don't see anything obvious in the configuration webpage for the DR4.
