Connection to fiber optic interfaces from third-
party suppliers (DIP 2)
•
Check the idle setting for the third-party interface:
–
Logic 1 = Light off or
–
Logic 1 = Light on
If necessary, adjust the idle setting of PSI-MOS using DIP 2.
9.4
Switches with no function (DIP 3, 4, and 5)
These switches are currently without function. They are re-
served for later additional functions.
9.5
Adjusting the transmission power (DIP 6)
If you use multimode fiberglass cables, you can adjust the
transmission power via DIP switches.
•
Set DIP 6 to "ON" (multi-mode) for operation on a multi-
mode fiberglass (50/125 µm or 62.5/125 µm).
•
Leave DIP 6 set to "OFF" (single mode) for operation on
a single mode fiberglass (9/125 µm) (factory setting).
If you are not sure which type of fiberglass is used in your
projects, contact your cable supplier.

–
If you switch DIP 2 to "ON," the FO diagnos-
tics are not available via the LED bar graph.
–
The LED bar graph can light up at high trans-
mission speeds or flash at low transmission
speeds. This display does
not
correspond to
continuous evaluation of the optical power.
–
When connecting third-party devices, ob-
serve the receiver sensitivity and overrange
limits of the fiber optic interfaces.
