Ok Rick, I am up against a wall. I have identified the system in question as a Type I. I even read a Maxtrac programmed on the system and got the size code (Motorola B) for the block I am interested in. After talking to some other people locally involved with the system I believe that all the blocks are probably the same size code. Now,,,,, I got as far as Insert and Fleet. How do I need to set this up? I reviewed your documentation and several threads on the subject but I keep coming up empty handed. I would certainly appreciate your help in setting this up.
