2.7.2 High-speed serial communication

To control the mirror to an arbitrary position by Marking or any other application, target position data

updated as required can be given to the controller by using high-speed serial communication.

By setting, the controller can be activated in the mode of tracking a target position specified by

high-speed serial communication.

(For details, see 6-1, “Setting Activation Mode.”)
