[Main and Sub system controllers (M-NET)]
Each group can be controlled by a Main system controller or a Sub system controller. EW-50 (AE-200/AE-50) is exclusively for use as a Main system controller and cannot be used as a Sub system controller.

Main system controller Main system controller refers to a system controller that controls all other system controllers including the units they control. If a given system has only one system controller, that controller becomes a Main system controller. Group settings and interlock settings can be made only from a Main system controller.

Sub system controller Sub system controller refers to a system controller that is controlled by a Main system controller.
