I recently acquired an est-2 and hooked up a DB-9 cable I made from the panel to a computer running XP. What is the easiest way to set up the programming software without a software key?

fyi ver 3.31 is the latest

Does that version work with all EST2 panels, or just ones that work with that version? If the later, how would I figure that out?
