POWER JACK
Connect the supplied power adapter to this input if power is not supplied via the terminals. The power adapter steps down 120/220 VAC to 9 VAC.
FIBER
The fiber input/output will accept 50/125, 62.5/125 and 100/140um fiber sizes using ST terminated cables. Care should be taken when removing the protective caps to prevent dust from entering the connectors.
POWER TERMINALS
The power terminals accept either 9 VAC or 9 VDC to power the F485 converter instead of using the power adapter. The GND terminal must be connected to ground to ensure adaquate protection against transients. Pin 4 is the main transient ground for the converter.
