J25 – Power Input
Power input for the Main Encoder PCB. This header also pr3.3V return from the Main Encoder
PCB to the I/O Jack PCB. The +12V input gets passed from here to the I/O Front End PCB via J7,
which in turn provides power to the Sony FCB-ER8300 block camera.
This header mates with J28 on the I/O Jacks PCB.
