Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
DXLink Fiber Transmitters, Duplex – LED Troubleshooting
If indicator LEDs for units do not respond with a normal display as stated in table on the previous page:
Check all power connections.
Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 52.
Try the suggestions in the “Troubleshooting” chapter (page 86).
For information on restoring the unit’s default settings on power up, see page 59.
DXLink Fiber RX – Attaching Signal, Transport, and Control Cables
Important:
Before attaching cables, be sure to set the DIP switch’s toggles if necessary (see page 40).
Tips for Fiber Optic Connections:
Keep dust plugs in transceivers until you are ready to make a connection.
Clean fiber optic cable ends before attaching to unit (be sure to follow the cable manufacturer’s instructions
for inspecting and cleaning the cable ends).
Use gentle pressure when connecting fiber optic cables to transceivers (normally an audible click is heard
when the connector engages).
If unsure the connection is properly seated, gently tug on the connector.
If fiber optic cables are removed from the transceivers, reinsert dust plugs.
Multimode transceivers only – If you are unsure that a multimode transceiver is passing a signal, hold the
unattached end of the fiber optic cable
away from you
and take a picture of it with a digital camera (or cell
phone camera). The image will show a bright light if signal is being passed (works on some digital cameras.)
Note:
Power, IR, and RS-232 ports are covered in their own sections.
To attach signal, transport, and control cables to the DXLink Fiber RX, Duplex:
1.
Clean the end faces on the fiber cable following the manufacturer’s recommendations.
2.
Fiber optic transceiver – Remove the dust plug (save for further use).
3.
Attach a fiber optic cable* to the fiber optic transceiver for transport from the switcher. Always grasp the fiber
connector housing to plug (or unplug) a fiber optic cable (depending on the housing, a click may be heard; if not,
lightly tug to be sure the connection is tight).
4.
HDMI Out connector – Attach the HDMI cable that goes to the destination device.
5.
ICS LAN 10/100 connector (optional) – Attach twisted pair cable from this connector to LAN. Note the #1 Toggle
on the DIP switch
must
be set to
ON
to enable this port. (For NetLinx programming information, see page 66.)
Important:
The illustration above shows duplex LC fiber cable; when using single LC fiber cables, be sure to
verify that the individual wires from the transceiver’s TX label on one end of the run are connected to the
transceiver’s RX label on the other end and vice versa.
Warning:
DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive on page 13).

Caution:
When you make the connection in Step 5, be careful not to create a network loop (see page 38).
