3) System diagram
Signals flowing between the control panel and the SYS 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 SYS board through the serial data. The state of the equipment and the mes-
sages from the SYS 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 output from the panel processing CPU,
based on serial data transmitted from the SYS board.
