DXLink TX/RX in a Multiple-Stage Switching System

When switching systems with DXLink Technology support (e.g., an Enova DGX Digital Media
Switcher and an Enova DVX-3155HD) are connected via their DXLink ports, DXLink Transmitters and
Receivers can be used to extend the video and audio transport.
Important: This section does not refer to the linking of enclosures from CPU to CPU, which is not
supported in the Enova DGX Digital Media Switcher or the Enova DVX Solutions.
In an installation with DXLink equipment in a multiple-stage switching system, the following apply:

Example
This example shows how DXLink Transmitters and Receivers can be used in a system where switchers
are connected via their DXLink ports.
The signal path through three switchers could be: source device
Enova DVX-3155HD, DXLink input (out a DXLink output)
DXLink output)
display device as an HDMI signal.

Network loops must be avoided (see page 40). The DXLink line's Ethernet functionality is
disabled between the enclosures; therefore, no IR, serial, or Ethernet communication can be
passed between them.
When two switching systems with DXLink support are connected via their DXLink ports,
only video and audio will be passed through the DXLink connection.
When a DXLink input or output on one switching system determines that it is connected to a
DXLink input or output on another switching system, the DXLink port will automatically
disable all Ethernet, power, and control on that connection port so that the only things passed
down the DXLink line are the video and audio signals.
When connecting switching systems via DXLink ports, AMX recommends no more than
three switcher throughputs (see the "Example" below).
