System Setup with DXLink Twisted Pair 4K Transmitters and Receivers

DXLink Twisted Pair 4K Input and Output Boards must be used in conjunction with AMX DXLink Twisted Pair 4K Transmitters
and Receivers or other AMX DXLink 4K signal management solutions. This combination creates an end-to-end extender
solution for transmission of HDMI (or DVI via adapter cable) over twisted pair cable.
Compatible DXLink Transmitters and Receivers are listed on page 124.

System setup options are listed in the table below.

For TX and RX installation details, see the Transmitter and Receiver's Quick Start Guide or Hardware Reference

Manual.
When compatible Transmitters and Receivers are installed in conjunction with DXLink Twisted Pair 4K Boards, image
adjustment and EDID scaling is automatically applied. For almost every installation, the automatic features on Transmitters
and Receivers result in a quality image on the monitor.
If the installation has special requirements and needs additional adjustment, see page 127. If you need additional
information on the Transmitters and Receivers or their specifications, refer to the Hardware Reference Manual – DXLink
Twisted Pair 4K Transmitters and Receivers at www.amx.com.
The distance from a Transmitter to a Input Board can be up to 262 feet (80 m) and another 262 feet (80 m) from the
Output Board to the Receiver.
IMPORTANT: Twisted pair cable runs for Input and Output Boards shall only be run within a common building. "Common
building" is defined as: Where the walls of the structure(s) are physically connected and the structure(s) share a single
ground reference.
NOTE: Along with the video signal, the DXLink Twisted Pair 4K Boards support embedded digital audio from the
Transmitters.

Options for DXLink System Setup

The following table contains several options in an Enova DGX Switcher for using DXLink Twisted Pair 4K Input and/or Output
Boards in conjunction with DXLink Twisted pair 4K Transmitters and Receivers.
NOTE: Transmitters and Receivers can be also be used together as a standalone solution without a switcher (Wallplate
Transmitters connected directly to Receivers must use DXLink power injectors); see the Hardware Reference Manual –
DXLink Twisted Pair 4K Transmitters and Receivers.

* If the board is a DXLink Fiber Board or DXLink Twisted Pair Board, it will need the appropriate Transmitter or Receiver;
see the table on page 45.
NOTE: Solecis 4K Digital Switchers (SDX-414-DX and SDX-514M-DX) have a DXLink Twisted Pair 4K output port that optionally
provides source point switching and distance transmission to an Enova DGX DXLink Twisted Pair 4K Input Board for hub-
style or campus-wide distribution.

Example of Typical Setup with DXLink Twisted Pair 4K Transmitter and Receiver

A typical system setup for a source and a destination is illustrated below and shows an Enova DGX 1600 with DXLink
Twisted Pair 4K Input and Output Boards used in conjunction with compatible Transmitters and Receivers for transport of
HDMI signals.
NOTE: This type of setup also supports DVI-D signals with the use of a cable adapter.
The Transmitter receives an HDMI signal and an embedded digital audio signal from a source device. Both the video and
embedded audio are transmitted over twisted pair cable to the RJ-45 connector on the DXLink Twisted Pair 4K Input
Board.
The signal is routed through the desired DXLink Twisted Pair 4K Output connector to the Receiver, which in turn sends the
HDMI signal with embedded audio on to a destination device. Audio received on the Transmitter can be output on the
Receiver's stereo audio port (FIG. 48):
