We all know how much fun it can be to figure out which output address on which universe equals which address number to assign to your mover. The ION does a nice job of dividing the outputs in groups of 512 outputs, but this still leave us with "what does mover address 77 on universe 3 equal for the output address"?
To help with this I came up with the equation A=512(U-1)+n, where "A" is the output address, "U" is the universe the mover is on and "n" is the address number assigned to the mover. So in this example:
A=512(3-1)+77 or 1101 for the output address of your board.
