Thanks
That is a good thing. Orange means short circuit protection is coming on. It is possible that you have a defective yellow LED. Check by measuring the white pin as it enters the DSC. It should normally be 5 volts. If not, you may have not powered the DSC. All three LEDs on the DSC need to be on and bright. Have you checked the black output of the sensor?
