Problem Possible Causes
Indicator LED is not on. Loose Power Connector: Verify that the power source connector is fully inserted
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 a power supply and that the power supply is energized.
Stand Alone Power Supply: 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.
Additional Information: See Power Options on page 6.
No video, intermittent
video or poor quality
video displayed. This problem has a number of causes. The most likely of which are shown in the
table below.
Cause Remedial Action
Tx and Rx are not aligned properly See Tx / Rx alignment recommendations on page 12.
DVI or SDI (Tx only) connections Confirm that the cables are properly connected.
Unsupported video mode
Verify that the applied video mode is supported. See the Supported
Video Modes table on page 20.
DVI or SDI (Tx only) cables
Replace the cables one at a time and check the video display. If the
video signal displays properly after a cable is replaced, discard the
cable you just replaced.
Tx and RX are spaced more than 30
feet (10 m) apart. Reduce the spacing between the Tx and Rx to 30 feet (10 m) or less.
See Tx to Rx Range specification on page 19.
Crosstalk See Avoiding Co-Channel Interference on page 14
Low signal strength See Signal Strength on page 16.
