HDMI TX or Multi-Format TX – Applying Power
Caution: If you are providing the power supply, use one that is UL (or equivalent) listed. To avoid
damage to the module, the electrical ratings (voltage level) for the power supply must not
exceed
those for the power jack as indicated in the “Specifications” table on page 22; doing so can result in
damage and voids the warranty.
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 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); see page 34.
Do not use local DC power jack on Module (even if local power adapter is turned off).
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 HDMI TX or Multi-Format 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.
HDMI TX and Multi-Format TX – Indicator LEDs
The LED indicators are listed in the table as they appear on the front of the module from left to right.
