Signals flowing between the control panel and the system board are indicated in the chart below. When the panel processing CPU detects that the control panel is operated, the operational contents are transmitted to the System board through the serial data. The state of the equipment and the mes- sages from the System board are received by the LCD controller and then displayed on the LCD.

The LED and buzzers are switched to ON/OFF with the signals from the System control PC board. The control methods of the LED and buzzers differ depending on the model:

e-STUDIO350/450:

They are switched to ON/OFF with the control signals from the System

 

control PC board.

e-STUDIO352/353/452/453: They are switched to ON/OFF with the signals output from the panel pro- cessing CPU, based on serial data transmitted from the System control PC board.
