Control Panel Processor Board
The Control Panel Processor board, mounted in the Main panel tub
between the two power supplies (
), provides the
control center for Main panel communication and operation. The board is
protected by a metal cover that can be easily removed for troubleshooting
or replacing fuses.
An on-board computer has the tasks of collecting panel switch, knob, lever
arm, and joystick movements and reporting these to the frame. It also
receives tally and state change information from the frame and updates
tally lights and displays based on the information. Power from the two
power supplies is distributed from this board to the other boards in the
Main panel as well as the Menu panel.
