Typical System Diagram
5.1 DVI Interconnections
1. Connect each strand of the fiber optic cable to the corresponding
optical ports on the Transmitter and Receiver units which are marked
with the numbers 1, 2, and 3.
2. Connect the Transmitter unit (red label) to the source (e.g., PC, Blu-
Ray, receiver/switcher output).
3. Connect the Receiver unit (blue label) to the display (or receiver input,
switcher input).
4. Connect the supplied AC Power Adapters to the power input jacks on
the Transmitter and Receiver units and then to an AC power source.
5. Turn ON the Display, and then turn ON switchers and other distribution
equipment (if it exists). Finally, turn ON the source. Test the system to
ensure proper performance.
5.2 USB Interconnections
This unit is equipped with a USB 1.1 port that supports remote extension of
certain USB devices over the optical link. USB 1.1 operation is supported at
different distances based on the required data rates:
• USB1.1LowSpeed:(Keyboard,Mouse):300meters+/-10%
• USB1.1FullSpeed:(ExternalHardDrive,memorystick,USBHub):

1. Connect a USB adapter cable with a Mini-B connector to the
port provided on the Transmitter unit. Connect the other end
of the cable with a USB standard-A connector to the host
USB device (such as a PC).
2. Connect a USB adapter cable with a Mini-B connector to
the port provided on the Receiver unit. Connect the other
end of the cable with a USB standard-A connector to the
downstream USB device such as a monitor, keyboard, or
mouse.
Note: To use both a keyboard and a mouse, use a USB to PS/2
cable.
6. TROUBLESHOOTING
If the system fails to display a signal, power OFF all devices and check that the
following connections are properly installed:
• TheTransmitterunitmustbeconnectedtotheSource.TheReceiver
unit must be connected to the Display.
• BoththeTransmitterandReceiverunitsmustbepoweredusingthe
supplied AC Power Adapters and must be connected to a known
working AC power source. Confirm there is power to both devices.
• Allthree(3)strandsoftheberopticcablemustberoutedtotheLC
optical port with the corresponding number on both the Transmitter and
Receiver units. For example, Fiber Strand #1 must be connected to
Optical Port 1 on both the Transmitter and Receiver units. This applies
to strands 2 and 3 as well.
Once all connections have been verified, power ON the monitor first, then any
intermediate equipment such as switchers, and finally the DVI signal source.
If the system still fails to display an image, check to ensure that the DVI signal
source is compatible with the display by making a direct connection between the
two so as to bypass the DVI-7335 DVI + HDCP Fiber Optic Extender. If there
is still no image, then there is a compatibility issue between the source and the
display that must be resolved.
After trying the above suggestions, should the problem still persist, contact your
dealer for additional suggestions. Should the dealer’s technical personnel be
unable to assist you, please contact DVIGear via telephone at 1.888.463.9927
