AR 9020 Pin Out Diagram
 

Some folks, like me, pull out an AR 9020 out of the drawer and can not get it to bind. I thought I was doing it right. But I only got one blink on a bind. Not wanting to fry it, I sent mine back for service only to get a call indicating that it was O.K. Rick at HH sent me the attached pin out diagram. Once I saw it, I remembered that the AR 9020's labeling is a bit miss-leading.

Yea, it's goofy the way they labeled that receiver.
