Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Power Issues
Upon power up, the Power indicator LED on the front of the DXLink units illuminates a solid green.
If the Power LEDs on any of the system’s equipment are not illuminated:
 Check the power cords or DXLink (RJ-45) connection if using power over the DXLink line.
 Check the power connections on the switcher if using power over the DXLink line.
 Check the power connections on the source and destination devices.
Important Power Considerations for Enova DGX 16/32 Endpoint Systems
Local power – Local power always takes precedence over power via the DXLink line from
the switcher. However, if a locally powered Module is connected to a switcher and the local
power is lost (i.e., unplugged or turned off), the Module 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/Wallplates are being powered by an Enova DGX16/32
DXLink board (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/Wallplates); see page 48.
Do not use the local DC power jack on the Module (even if the local power adapter
is turned off).
Power Issues with Enova DGX 16/32 Endpoint Systems
In an Enova DGX 16/32 Endpoint System when multiple endpoints (Transmitters/Receivers) cycle their
power and the DXLink connection fails, check the following:
 Check to be sure that Transmitters/Receivers being powered by the local DC jack have power.
(Local power always takes precedence.)
 Check to be sure that Transmitters/Receivers intended to be powered via the DXLink line
do not have a DC jack plugged in even if the local power adapter is turned off. This can cause
inadvertent ground loops that can negatively affect DXLink power sensing circuits.
