Hardware Reference Manual – DXLink™ Twisted Pair 4K Transmitters/Receivers
Extender Mode (Standalone): Example of Typical System Setup
A Transmitter and Receiver standalone pair can also work together as an extender solution for transmission of HDMI over twisted
pair cable up to 262 feet (80 m). The standalone setup supports DVI-D signals with the use of a DVI-to-HDMI cable adapter.
In systems with a Wallplate Transmitter, power can be provided to the units via the DXLink line by connecting a DXLink power
injector to the Wallplate and using either the desktop power supply or another DXLink power injector with the Receiver.
Important Power Considerations for Enova DGX Systems
Local power
– Local power (the desktop power supply) always takes precedence over power via the DXLink line from the
switcher. However, if a locally powered unit is connected to a switcher and the local power is lost (i.e., unplugged or turned
off), the unit will power down and then automatically power back up using power from the switcher via the DXLink
connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the
power over the DXLink line.
DXLink power
– When modules are being powered by an Enova DGX DXLink board, PDXL-2, or PS-POE-AT-TC (using power
via the DXLink line), to maintain the switcher’s power redundancy, we recommend that you:
Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (modules);
see below.
Do
not
use the local DC power jack on the module (even if the local power adapter is turned off).
Power Budget Planning for System Setup with an Enova DGX
Before installing an Enova DGX Digital Media Switcher and connecting any required DXLink Transmitters and Receivers, the total
power draw for the system should be calculated in order to maintain the redundancy of the power supplies in the enclosure. (Each
Enova DGX enclosure ships with two mutually-redundant power supplies.)
IMPORTANT:
If you do not plan to draw power from the Enova DGX enclosure’s power supplies, you must power the DXLink
Transmitters and Receivers with local power (desktop power supply) or remote power (DXLink power injector), which always overrides
power from the switcher. If that power source is turned off, the DXLink Transmitters and Receivers will reboot and then start drawing
power from the switcher.
Power Budget Calculation
Calculating the power budget helps determine how many DXLink Transmitters and
Receivers can be powered through the Enova DGX Digital Media Switcher while
maintaining power redundancy if one of the power supplies should fail. The
Enova
DGX Configuration Tool
is used to determine the switcher’s power budget. Simply
enter the types of boards and the number of DXLink Transmitters and Receivers to
be powered through the switcher, and the calculator shows the resulting power
draw. The
Enova
DGX Configuration Tool
is at www.amx.com/enova.
If more DXLink units are required than the switcher can support while maintaining
redundancy, any DXLink Modules can be powered using the provided desktop
power supplies or DXLink Power Injectors: PDXL-2 (FG1090-170) or
PS-POE-AT-TC (FG423-84).
Wallplate Transmitters
must
be included in the power calculations unless they are
being powered by a DXLink power injector (
must
be AMX approved).
IMPORTANT:
AMX does not support the use of any power supplies other than the
provided ones or power injectors other than the ones approved as they may
potentially damage the DXLink equipment.
DXLink-compatible Power Injectors
The only approved power injectors for DXLink hardware are: the PDXL-2 (FG1090-170) which can provide power for up to two
devices (e.g., DXLink Transmitter and Receiver in Standalone setup) or the PS-POE-AT-TC (FG423-84) which can provide power for
one device.
