1-4. Outline of Communication
A controller (PC) communicates with a display according to the communication data format. Communication is started by
issuing a command from the controller. Communication is terminated when the display sends return data (an answer mes-
sage) to the controller after it receives the issued command.
It is inhibited that a controller sends multiple commands at a time.
Therefore, a controller cannot send other commands until return data is sent back from a display after it sends one com-
mand. The display sends return data after command processing is completed.
