Hello group, first I have had the old controller from Deepgroove1 for many years now (maybe 10?) and have really good service from that old controller but I have recently upgraded to the gecko controller from Deepgroove1 and ordered every option that Deepgroove1 offered like the relay and home switch jack because once I order may not be able to add them later.
So here are my questions...
1. What does the relay do and where is it located in or outside the box? (see attached photos).
2. What does the home switch jack do and where is it located in or outside the box? (see attached photos).
3. Also there is two plugs on the right in the back and I know the bottom one is for the power cord but what would you plug into the top one?
I don't know a lot about electronics and don't what to do something wrong on a new controller.
Thanks,
Eric
