[QUOTE="Cee DeLights, post: 104986, member: 28793"] Hi Grant, First off, note the Rpi GPIO pins you are using for the relays. For Example Relay1 = GPIO13, Relay2 = GPIO6, Relay3 = GPIO5 etc. Then in FPP, map the first GPIO Output type to StartCh=1 and set this GPIO13. Proceed with the other relays. [ATTACH type="full" width="636px" alt="RpiRelay4PNG.png"]13951[/ATTACH] You may note that I selected Invert since my relays are toggle on when High (or vice versa, I can't remember :rolleyes:) In Vixen, create Elements for the number of relays, then patch these to Generic Serial ports The Generic Serial Ports references Channel 1,2 and 3 in FPP. Likewise, the Elements, allows you to create your Vixen sequence and know which Relay to activate in your sequence design. [ATTACH type="full" width="569px" alt="Vixen1.PNG"]13952[/ATTACH] In the Vixen sequence editor, set the Color gradient to High or Low. For example, Ive used the Alternating effect and set the color White to be HIGH and Black to LOW. You change the gradients by moving the gradient bar High or Low as shown in red and yellow. This will signal the appropriate On / Off triggers within FPP. Hope that helps. [ATTACH type="full" width="470px" alt="Vixen3.PNG"]13953[/ATTACH] [/QUOTE]

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