Say you make a change to one of your programs using Xchange 2, and want to overwrite the program you just changed onto your detector. What are the steps. The way I've been doing it is, I delete my programs off of my detector, make a change on the Xchange 2, and then reload the programs onto my detector. I know there should be a way to just overwrite the One program I've changed, without deleting programs from my detector. I just haven't figured out how. Help Please and thank you.
