2.7. Control Specifications The controller (GC-201, GC-101) is operated by: • RS-232C command input • High-speed serial communication In addition, either the internal clock or external clock (high-speed serial communication) can be selected for operation. External Clock Internal Clock (High-speed serial communication) Clock pulses generated by the High-speed serial communication Clock input controller internal circuit clock pulses RS-232C command High-speed serial communication

Parameter of controller can be changed by the following sending method to controller. Also in response to parameter send, the controller always returns a reply with data. The data contents depend on the command. (For details, see 7-2, “Command Details.”) When changed a parameter of it, to start it by the same setting in power supply on at the next time; the parameter that changed, it is necessary to write in it at ROM.

For the ROM Write of the parameter, a reply with data has been sent by all means by a controller. The content of data is different by a parameter. (For details, see 7-3, “Parameter Details.”) Note Please make the ROM write of the parameter after enough confirmation. Depending on value for change, the controller may not start normally.

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.
