John,
I have two old ERR AC Commanders from the previous company. Is the layout the same. Are the screw terminals all the same as they are now, or did 3rd Rail change things. I am asking because I want to be aware of any changes when I go to use these older boards. I also have two older Railsounds boards that were purchased back with the AC Commander boards as well. I do not think I have instructions from the previous company.
Mark
