O stands for open centre
Open centre means that this unit is designed for open systems.
In the neutral position there is an open connection between the pump and the tank.

N stands for non-reaction
This means that external forces acting on the wheels do not cause the steering wheel to turn when the steering unit is in the neutral position.
