Hardware Reference Manual – DXLink™ Twisted Pair 4K Transmitters/Receivers
DXLink 4K TX/RX in a Multiple-Stage Switching System
When switching systems with DXLink Technology support (e.g., Enova DGX 100 Series Digital Media Switchers) 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 Enova DGX 100
Series Digital Media Switchers.
In an installation with DXLink equipment in a multiple-stage switching system, the following apply:
Network loops
must
be avoided (see page 24). 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 4K 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
