2.3.7 Optical conversion PCB assy.
 Outline
Unit name: Optical conversion PCB assy.
 Main specifications
The main PCB and the HDC PCB are relayed by this PCB. The PCB is placed within the electrical box and on the
carriage, and the electric signal within the FFC is optical-converted then transmitted by the optical fiber.
Additionally, the PCB relays to supply the power (DC37V) to the HDC PCB.
