Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Multi-Format TX or HDMI TX – Applying Power
Important:
If desktop power is used to power the Transmitter, only the provided desktop power supply should
be used and it must not be altered in any way. Remote power can only be provided via a switcher or a DXLink
power injector. AMX does not support the use of any other power supplies or power injectors as these may
potentially damage the DXLink equipment.
Important Power Considerations for Enova DGX Endpoint Systems
Local power – Local power (desktop power supply) 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 are being powered by an Enova DGX DXLink board or DXLink power
injector (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 page 41.
Do
not
use local DC power jack on module (even if local power adapter is turned off).
Note:
When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground
for the ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher
(see page 47).
The following instructions do not apply if you are using power from the switcher via the DXLink line in an endpoint
system.
To apply power to the Multi-Format TX or HDMI TX:
1.
Plug the cord from the desktop power supply (provided) into the power jack on rear of the module (2.1 mm DC jack
for 12 V local power).
2.
Plug the desktop power supply into an AC external power source.
The Power LED on the front of the module turns a constant green, which
indicates a ready state.
Some of the additional LEDs also turn a constant green. For normal LED display, see table below.
Multi-Format TX and HDMI TX– Indicator LEDs
The LED indicators are listed in the table as they appear on the front of the module from left to right.
