Newbie,with (7)nec 1300a in dvd3000 duplicator

hi,i’m new and don’t know much about all this,but i have a wytron 3000 dvd duplicator with 7 nec 1300a’s and i wanted to know how i can update the firmware on them.they all have different firmware updates and i can’t seem to get it to burn dvd’s.also does anyone know if i can use a 1300a as the dvd reader on my duplicator tower or will it not read from it?

                                                       thanks all,summer
