Here is a discussion forum post that gives some details on the different types of triggers that can be setup: http://forums.ni.com/ni/board/message?board.id=200&message.id=1474&requireLogin=False
I hope this gives you a better idea of the settings availlable in MAX to configure the trigger. I can take a further look into this, and give you some more information soon.
