I don't really know but it should be easy for you to find the answer, it's already been discussed a lot here.... I know you have to run full bitcoin node on pc, and then basically point your mining hardware to your pc instead of the pool or something, don't quote me on that though.
Sure, why don't you just ask your friend if he is already set up?
my friend is not using S1's we has home built boxes but thanks for the insight - much appreciated - I will continue to scour the forum looking for an answer.
