Hardware Reference 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 DX-TX and DX-RX pair can also support an analog video source.
In 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 DX-RX.
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).
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 37).
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.
