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.
