Hey Ted, that tool will access a variety of Otis equipment, although most of the operations are similar, there are still subtle differences. I'm not sure anyone on this site will say "outloud", here is the manual, enjoy. If you are an elevator man, you must have some friends who could supply that info nonchalantly, you can never tell who is reading these posts, and what there true intentions are. That is proprietary info your asking for, the transfer of that info needs to be done discreetly. I'm sure all the companies know there info is being shared by our union brothers, it is better to not advertise such transfers .
