I have a copper vapor system with two STP-8 actuators to change from green to yellow. I can not seem to get the actuators to respond properly. I have wired them to the green and yellow pins on the DB25 and grounded the (-) input since these have a single ended input. I train the pallette with all 0 on the pallete except the primary green and yellow for which I set 100 on the corresponding color. When I then activate say a red frame I would think that neither actuator should be active but I am getting what looks like pulses to the green channel. Also when I put a solid green image the green actuator is still pulsing instead of solid. Are the signals from the QM2000 pulsed in any way?
