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 45).
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.)
