Flickering light program

Hello,

I'm excited, I'm setting up my first Prop-1 to FC-4 connection and I was wondering if someone has a code for the effect of lights flickering and fading like they might die.  I also have a question about the setup.  I have 6, 25W lightbulbs in different rooms that I would like to have this effect on.  I know each channel can power up to 300W so should I run them all off one channel or do 2,2,1, and 1?  Or does it just depend on how the code is set up?  Thanks.

No, I don't have one. But, if you look under documents of this site you will find FC-4 PDF that will provide you with a demo program.

To answer your question about the wattage of each channels, I think it is around 150 watts per channel. The FC-4 document will answer this question as well.

Here's a program to try; do review the FC-4 docs for connections, setup jumpers, etc.

Sorry... my FC-4 demo is on loan so I can only write and compile this program; that said, it's pretty easy and I think it will work for you.  Please study it so you can make adjustments once you have everything up and running.
