5 ZEROWIRE® G2 Troubleshooting
Problem Possible causes Remedial action
Indicator LED is not on
Loose power connector
Verify that the power source connector is fully inser-
ted into the unit’s power connector.
Y cable
If you are using the Y cable to supply power to the
unit, confirm that it is connected to an NDS 24VDC
power supply and that the power supply is energized.
Stand-alone power sup-
ply
If the stand-alone power supply is being used confirm
that it is fully inserted into the wall socket.
Wall socket
Some wall sockets have ON/OFF switches built in.
If the socket you are using has a built in switch, check
that it is in the ON position.
See section Power Options [
}
17] for additional information.
No transmitter found
The Transmitter is OFF, or
the cable from the video
source is not connected,
or the video source is
OFF.
Verify the Transmitter unit is ON or source signal is
connected.
No image on display after
changing input resolution
The Transmitter or the
Receiver cannot lock to
the video signal.
Cycle the ZEROWIRE® G2 Transmitter’s and Receiver’s
power, not the display.

attempting to pair
The Transmitter and the
Receiver units cannot ne-
gotiate the RF Channel to
connect on.
Cycle both ZEROWIRE® G2 Transmitter’s and Re-
ceiver’s power.
