Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
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:
Network loops
must
be avoided (see page 33). 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).
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
DXLink Transmitter
Enova DVX-3155HD, DXLink input (out
a DXLink output)
Enova DGX 32, DXLink input (out a DXLink output)
Enova DGX 16, DXLink input (out a DXLink output)
DXLink Receiver
display device as an HDMI signal.
