Power Handling
7. Connect one end of the supplied fiber optic cable to the Fiber Optic Connector
on the Fiberlink NNI Transmitter.
8. Connect the other end of the supplied fiber optic cable to the Fiber Optic
Connector on the Fiberlink NNI Receiver.
9. Connect the supplied NNI cable from the Fiberlink NNI Receiver to the input
connector of your NNI LED wall.
For a diagram showing the cabling between these units, see “Fiberlink NNI
system block diagram” on page 206.
10. Connect power to the Fiberlink NNI Receiver.
11. On MatrixPRO, use the Set up Wizard or Director Toolset 2.0 to set up your
outputs and detect the tiles.
12. From the Home Menu, press {Display Management} to display the Output
Selection Menu.
13. Immediately above the graphic, press the button for the Bank that contains the
output whose LED display you wish to force on.
14. On the selected bank, press the output that you wish to manage. The Display
Management Menu appears.
15. Press {Force Display On} to turn on the selected wall’s power.
16. Check the status of the LEDs on the Fiberlink NNI Transmitter and Receiver
modules. All LEDs should be green, to indicate signal continuity throughout the
entire data path. LEDs should not be blinking on the Fiberlink NNI Receiver.

The Fiberlink NNI has the ability to "start up" the LED tiles. When the DX-700 is connected
to the tiles directly, this is accomplished by switching on the DC supply output on the NNI
interface. Likewise, the tiles are shut down by turning off the DC supply.
This capability is maintained when the Fiberlink NNI system is connected between the
MatrixPRO and the NNI LED tiles. By using the {Force Display On} and {Force Display
Off} feature in the Display Management Menu, you have the ability to control the wall
“remotely.”
Please note:
•The Fiberlink NNI Transmitter acts similarly to a directly connected tile: It is
turned on by the DC supply from the MatrixPRO, and it turns off when the supply
is turned off.
•The Fiberlink NNI Receiver is powered by the AC mains, and will always be on if
the mains are connected.
•The Fiberlink NNI Receiver supplies the power that starts up the tiles. The unit
monitors the fiber cable input. If a carrier is detected, the receiver supplies power
to the tiles. If no carrier is detected, the power remains off.
