Principles of Operation
Video Controller Operation
The video controller section generates the video signals for the received data. The
video controller section is separate in the C125 MAIN board and the control panel.
The control panel is connected to the engine controller board (PWB-A), but is
controlled by the C125 MAIN board, which sends the signals for the control panel
through the engine controller board.
