HDMI RX – Applying Power
Caution: If you are not using the provided power supply, use one that is UL (or equivalent) listed. To
avoid damage to the HDMI RX, the electrical ratings (voltage level) for the power supply must not
exceed those for the power jack (see “Specifications” table on page 22); doing so can result in
damage and voids the warranty.
Important: The “Important Power Considerations for Enova DGX 16/32 Endpoint Systems” also
apply to the HDMI RX (see page 48).
To apply power to the HDMI RX:
1.
Plug the cord from the desktop power supply (provided) into the power jack on rear of the
HDMI RX (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 HDMI RX illuminates a constant green, which indicates a ready
state. Some of the additional LEDs will also turn a turn a constant green. For normal LED display,
see the table below.
Important: If any HDMI Receivers are being powered through an Enova DGX, we recommend
determining the power budget to maintain power redundancy for the system (see page 34).
HDMI RX – Indicator LEDs
The LED indicators are listed in the table as they appear on the front of the RX from left to right.
* If the output cable is disconnected from the HDMI RX or if no EDID can be found on the destination device, the
Bypass LED will be constant green and the Auto LED will blink. This indicates that the HDMI RX has switched to
the Bypass scaling option and is waiting for EDID information. As soon as a valid EDID is found, the HDMI RX
will revert to the Auto scaling option.
Receiver – LED Troubleshooting
If the indicator LEDs for the modules do not respond with a normal display as stated in the table above:
 Check all power connections.
 Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 55.
 Try the suggestions in the “Troubleshooting” chapter (see page 91).
For information on restoring the module’s default settings on power up, see page 61.
