Additional Notes from the Image
Overview:
The module connects to the drive (NAMC/NDCO board) via fiber optic cables. Please note the color coding of the fiber optic connectors:
Blue connector should connect to the Blue receiver (RXD).
Grey (or Black) connector should connect to the Grey transmitter (TXD).
Multiple modules in a single channel are connected in a ring topology.
Handling Precautions:
Handle fiber optics with care.
Maximum long-term tensile load: 1 N.
Minimum long-term bend radius: 25 mm.
Do not touch the fiber optic tips; they are very sensitive to dust.
Use grommets where fiber optics pass through holes.
Terminals:
The terminals connected to NTAC-02, NDIO-02, and NAIO-03 modules are shown in the table above.
