The CPU on the main controlled PCB sends data (display data) to the control panel CPU PCB as instructed by the program.

The data is sent through the control panel PCB to reach the color LCD.

- Monitoring the Key Inputs

It communicates the keypad and function key inputs to the CPU on the main controller PCB.

- Monitoring the Touch Panel Input

It communicates the key inputs made on the touch panel to the CPU on the main controller PCB.

- Controlling the Buzzer Sound

- Controlling the Control Panel LED

MEMO:

The color LCD is driven by the main controller, and the control panel CPU PCB serves to relay the drive signals.
