DXLink Transmitter/Receiver Grounding
When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground
for the ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and
switcher. For complete grounding information, see the Instruction Manual – DXLink™ Twisted Pair
Transmitters/Receiver.
Important: If one DXLink Transmitter or Receiver is grounded, any remaining ungrounded units that
are connected to the same board on the Enova DGX Switcher must also be grounded.
Example of Typical Setup with DXLink Transmitter and Receiver
A typical system setup for a source and a destination is illustrated below and shows an Enova DGX 16
with DXLink Boards used in conjunction with DXLink Transmitters and Receivers for transport of
HDMI signals. This type of setup also supports DVI-D signals with the use of a cable adapter and analog
video through a Multi-Format TX, Wallplate TX, or Decor Wallplate TX.
The 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, digital audio over S/PDIF, or analog stereo audio.
Both the video and embedded audio are transmitted over twisted pair cable to the RJ-45 connector on the
DXLink Input Board. The signal is routed through the desired DXLink Output connector to the DXLink
Receiver, which in turn sends the HDMI signal with embedded audio on to a destination device. Audio
(whether embedded or not) received on the Transmitter can be output on the stereo audio port.
Tip: For systems with special requirements – Before installing in the final location, place the
equipment close together, so a PC for control and the destination monitor can be seen
simultaneously if adjustments are necessary. Adjustments can be made using DGX Configuration
Software (see page 157).
Caution: Be careful not to create a network (Ethernet) loop. To avoid doing so, see page 89.
