Acorn Six encoder / Mag Scales

Acorn Six has three encoder inputs. Will they work with my current magnetic scales? Precision Matthews MagAct 200.
With three encoder inputs used, What about the spindle encoder ? Plan is to set up for mill/turn machine.

If you want to use 3 scales and spindle encoder, you need the encoder expansion board.
If your scales are compatible depends on if they have RS422 output, TTL may work with a line driver converting TTL to RS422
