I Switch Setting
There are four switches on the rear of the controller for specifying the terminal definition and data communication conditions.
A signal form selection switch (SW1) and a character display mode switch (SW100) are mounted inside the controller. These
inner switches do not need to be adjusted when the controller is used with the factory default settings.
