Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
DXLink Fiber TX – 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 the signal is being passed (works on some digital
cameras and cell phone cameras).
Note:
Power, IR, and RS-232 ports are covered in their own sections.
To attach signal, transport, and control cables to a DXLink Fiber TX, Duplex:
1.
Video In connector – Attach the HD-15 cable from the source device to the Video In connector (for pinouts for
VGA, component, S-Video, and composite, see page 117).
2.
HDMI In connector – Attach the HDMI cable from the source device to the HDMI In connector.*
3.
Clean the end face on the fiber cable following the manufacturer’s recommendations.
4.
Fiber optic transceiver – Remove the dust plug (save for further use).
5.
Attach a fiber optic cable to the fiber optic transceiver for transport to 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).
6.
Digital Audio In jack (optional) – Insert the S/PDIF (RCA) plug on the digital audio cable from the digital audio
source into the Digital Audio In jack. For audio precedence information, see page 42.
7.
Stereo Audio In jack (optional) – Plug in the analog audio cable from the stereo audio source into the Stereo Audio
In jack. For audio precedence information, see page 42.
* DVI cable can be used instead (via a DVI-to-HDMI cable).
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).
