Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
The following instructions do not apply if you are using power from the switcher via the DXLink line in an Enova DGX system.
To apply power to the DX-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.
DX-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.
DX-TX and HDMI TX – LED Troubleshooting
If indicator LEDs for modules do not respond with a normal display as stated in table above:
Check all power connections.
Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 50.
Try the suggestions in the “Troubleshooting” chapter (see page 83).
For information on restoring the module’s default settings on power up, see page 57.
