ATV1200 fiber optic board

The function of the fiber optic board is to convert the control signal (trigger pulse, bypass control signal, pulse blocking signal, etc.) of the main control board to the power unit, and convert it into a serial optical signal and output it to the power unit through optical fiber. Convert the optical signal transmitted by the power unit into an electrical signal (mainly the fault information of the power unit), and convert it from serial to parallel, and pass it to the main control board for processing. The fiber optic board also detects the communication and reports the communication failure when the communication cannot be established.
