Installation Instructions
This product consists of a DVI-7317-TX Transmitter Unit and a DVI-7317-RX Receiver Unit. These units
are interconnected by means of 1x LC-terminated optical cable, utilizing either 50/125μ Multi-Mode
fiber or 9/125μ Single-Mode fiber. For maximum cable lengths, please see the chart on page 4.
1.)
Apply the included heat insulation pads on the sides of the TX and RX units in the spaces
shown.
See the warning above.
(2)
2.)
Connect the TX unit to the output port of the signal source (e.g. PC or Blu-ray player).
3.)
Connect the RX unit to the input port of a destination device (e.g. display or projector).
4.)
Each unit has one (1) Optical port. Connect an LC-terminated fiber optic cable between
the TX unit and the RX unit.
5.)
Connect the included External AC Power Adapters to the USB Micro-B port on the TX as
well as the RX. Then connect the power adapters to working outlets. Alternatively, it is
also possible to power the TX from a USB port that can supply adequate power. To do
this, connect the USB Micro-B port on the unit to the USB port on the source device using
an appropriate adapter cable (see below for details).
6.)
Apply power to the display device, then apply power to the source device. A picture should
appear on the display within a few seconds.
Power Sources
The TX unit can be powered using either the supplied External AC Power Adapter or a functioning USB
port. In installations in which a USB port will be used to provide power to the TX, it is important to be
certain that adequate power is available on the USB port being used. Additionally, in this case, a USB
Type A Male to USB Micro-B Male Adapter Cable such as DVIGear’s DVI-7316-USB1 should be used.
