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.

With the default settings at shipping, power-on activates the controller with the internal clock. 

The parameter can be set so that the controller starts with the external clock after power-on. 

For activation with the external clock, however, signal input by high-speed serial communication is 

necessary at power-on.
