[QUOTE="TommyOrlando, post: 123023, member: 36329"] The card is a Sainsmart 16 channel relay SKU: 101-70-103. The pins on the relay have 5V printed on them. I have tried both the 3.3V and 5V outputs from the Pi. The 3.3V on the Pi to the 5V pin on the relay got them to work when I have the Regular Pi SD card in and run simple scripts to snap the relays on and off. I can do that with Python coding. Everything on the relay looks like 5V should be fine. I'm getting convinced the FPP settings are wrong. I have one too many or one missing check box somewhere. I'm understand all of this new stuff I am reading, but I'm not electrically minded.... Something simple somewhere is missing. [ATTACH]19064[/ATTACH] (Photo w. magnifying glass...) [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
