I was thinking the same thing, why spend 5000 at world to interface only the miprom 21, when you can get this unit from kone spares, and it will talk to a variety of none equipment i listed above.. world wants around 1300 just to get the tool that talks to that MAc marathon/ WG door operator, what a monstrosity is right. i had the pleasure of replacing one of those cables as i noted on an earlier post, it was not pleasant. especially since i was not the one who took it off. and no manuals. ps I'm not very mechanically inclined, that also hindered my performance.

how much is the tool from cetek?
