FIBER OPTIC SC DUPLEX A/B/C/D/OFFLINE APPLICATION: The SC Duplex 100BASE-FX Auto Fallback block diagram illustrates an external OFF-LINE position, as well as, the A, B, C, and D positions. A fiber optic device connected to the COMMON port has access to four fiber optic networks connected to the the A, B, C and D ports, or be completely disconnected from all output ports in the OFFLINE  position. A workstation connected to the DB9 Remote port allows the user access to select positions A, B, C, D or OFFLINE remotely. Applying the appropriate voltage to the desginated pins of the DB9 REMOTE connector will cause the switch to change position.
