Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
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 328 feet (100 m). The standalone setup supports DVI-D signals with the use of a
DVI-to-HDMI cable adapter. A Multi-Format TX and HDMI RX pair can also support an analog video source.
In Extender systems with a Wallplate TX or Decor Wallplate TX, 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 HDMI RX.
Important Power Considerations for Enova DGX Endpoint 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).
Note:
When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground
for ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher (see
page 47).
Power Budget Planning for System Setup with an Enova DGX
Note:
This section does not apply to the Enova DVX Solutions due to their minimal number of DXLink
connections.
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 Transmitter and Receiver Modules 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.
