6. Initial settings

• When connecting multiple system controllers, designate the system controller with many
functions as the "master", and set the system controllers with few functions as the "slaves".
(Refer to section 8. Setting the functions, "8-1 Using with master system controller" for details
on the "master/slave" settings.)
• If this controller is controlled by the master system controller, carry out the initial settings with
the master system controller. In this case, this controller will use the slave settings, and does
not require initial settings.
