Instruction Manual – DXLink Fiber Transmitters and Receivers
Endpoint Mode (Switcher): Example of Typical System Setup
The primary function of the DXLink Fiber Transmitters and Receivers is to work with compatible DXLink Fiber
equipment as an endpoint solution for transmission of HDMI or analog video signals over fiber optic cable (or DVI-D
signals via a DVI-to-HDMI cable).
The DXLink Fiber Transmitter receives an HDMI signal and an audio signal from a source device. The audio can be
either digital audio embedded with the HDMI signal or analog stereo audio. Both the video and embedded audio are
transmitted over fiber optic cable to a fiber optic transceiver on the DXLink Fiber Input Board. The HDMI signal is then
routed through any (or all) of the fiber optic transceivers on one or more output boards. The HDMI signal can also be
routed through any other types of boards in the system.
When the HDMI signal is routed through a fiber optic transceiver on a DXLink Fiber Output Board to a DXLink Fiber
Receiver, the Receiver sends the HDMI signal with embedded audio on to the destination device. The audio can also be
output on the Receiver’s stereo audio port.
In a system where DXLink Fiber Transmitters and Receivers are used in conjunction with an Enova DGX 8/16/32/64,
the cable runs from a Transmitter to a DXLink Fiber Input Board and from a DXLink Fiber Output Board to a Receiver
depend on whether the transceivers are single mode or multimode and on the quality of the cable (see cable
specifications on page 32).
Tip:
For systems with special requirements – Before installing in the final location, place the equipment close
together, so that the destination monitor and a PC for control can be seen simultaneously if adjustments are
necessary. Scaling adjustments can be made using SEND_COMMANDs (see page 77). For Enova DGX
Digital Media Switcher systems, DGX Configuration Software can also be used to make scaling adjustments
via the switcher (see the switcher’s “Instruction Manual”).
Custom EDID Settings
If your system has special EDID requirements, see page 141 for information on managing and programming custom
EDIDs.
Important:
Compatibility between hardware requires matching model types: multimode to multimode and
single mode to single mode.
