I've seen this question posted a time or 2, but it never results in a definitive explanation, so I'm going to give it another ask.

I've got a C3 card and a G540. My C3 is supposedly the revision that will play well with the G540. I don't have any additional BOB's of any type, only the G540

So how do I connect the C3 output to the G540?? Please, keep it dumb so myself and others can benefit from the explanation. Thank you!
