5. Troubleshooting
No power status light on receiver
• Verify that the power supply is plugged in correctly.
• Ensure that the power cable from the Black Box-supplied power supply is securely
plugged into the receiver.
No video on monitor attached to receiver
• Verify that the monitor attached to the receiver has power.
• Ensure that the video cable from the monitor is securely plugged in to the correct
connector on the receiver.
• Verify that the remote computer is powered.
• Confirm that a network connection exists between the transmitter and receiver.
• Verify that the address of the target transmitter that is configured in the receiver is
correct.
• Confirm that the IP address used by the transmitter has not been assigned to a second
device on the network.
• Confirm that the IP address used by the receiver has not been assigned to a second
device on the network.
• Verify that the DTX5000-T transmitter is drawing sufficient power from the USB
connections on the remote computer and that it has booted correctly:
• If the green LED on the transmitter is on, the transmitter is drawing sufficient
power.
• If the transmitter cannot draw sufficient power from the remote computer you
will need to obtain an external power supply unit for the transmitter from Black
Box. If connected through a USB hub, ensure that the hub can supply enough
power.
• Verify that the correct video setting has been configured in the transmitter serial
menu:
• If the remote computer provides DVI only video, verify that the transmitter
serial menu has been configured for DVI. Then restart the remote computer.
• If the remote computer provides VGA only video, verify that the DTX5000-T
transmitter serial menu has been configured for VGA. Then restart the remote
computer.
• The transmitter has an internal fan. Verify that the fan is functioning.
• Cycle power to the receiver. An informational message should appear on the monitor
for a brief moment. If the message does not appear, check the monitor by plugging
the video cable from the monitor directly into the remote computer to verify that the
monitor is working and that the remote computer is generating active video. If this is
functioning, check that the display settings for your remote computer are set no
higher than a resolution of 1280 x 1024 at
60 Hz refresh rate. If the monitor does not
function correctly, replace it.
