Lots of controversy on wiring a console as far as how many power tn's to use. Some use 2, some use 3, some dont use any. Some dont even use a 25 pr. cable. But if you do it by the NTP you are sure to be successful. One other thing to keep in mind is if you use night mode all consoles have to be in night mode. If they arent all in night mode the will show "position busy". I believe you can do "shift" plus night mode from one console and that will put them all in nights.
