Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Endpoint Mode (Switcher): Example of Typical System Setup
The primary function of the Transmitters and Receivers is to work with compatible DXLink equipment as an endpoint
solution for transmission of HDMI over twisted pair cable (or DVI-D signals with the use of a DVI-to-HDMI cable
adapter, or analog video signals 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 (S/PDIF is not available on the Wallplate TX or Decor
Wallplate TX), 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 HDMI signal is then routed through any (or all) of the connectors on
one or more output boards.
When the HDMI signal is routed through a DXLink Output connector to a DXLink HDMI 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 systems where DXLink Transmitters and Receivers are used in conjunction with a switcher (e.g., the Enova DGX 16),
the cable runs from a Transmitter to a DXLink Input Board and from a Receiver to DXLink Output Board can each be up
to 328 feet (100 m).
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 78). For Enova DGX
Switchers, DGX Configuration Software can also be used to make scaling adjustments via the switcher (see
the switcher’s “Instruction Manual”).
Caution: Be careful not to create a network (Ethernet) loop. To avoid doing so, see page 43.
Custom EDID Settings
If Transmitters are part of an Enova DGX system which requires custom EDID settings,
see the switcher’s Instruction Manual for information on the EDID programming functionality in
DGX Configuration Software (available at www.amx.com
). SEND_COMMANDs can also be used
(see page 78).
If Receivers are part of an Enova DGX system which requires scaler control and settings, see the switcher’s
Instruction Manual for information on the scaling functionality in DGX Configuration Software (available
at www.amx.com
). SEND_COMMANDs can also be used (see page 78).
