No power status light on transmitter or receiver

Verify that the green LED on the separate Avocent-supplied power supply is illuminated, indicating that the power supply is plugged in correctly.

Ensure that the power cable from the Avocent-supplied power supply is securely plugged into the LongView Wireless transmitter or LongView Wireless receiver unit.

As a last check, plug the video cable from the monitor directly into the computer to verify that the monitor is working and that the computer is generating active video. If this is functioning, check that the display settings for your computer are set no higher than a resolution of 1024 x 768 at 60 Hz refresh rate. If the monitor does not function correctly, replace it.

No mouse and/or keyboard operation from peripherals attached to transmitter

Verify that the mouse and keyboard are connected to the correct PS/2 ports on the computer. Match the connector color codes (green is mouse and purple

If the LongView Wireless transmitter was powered up after the computer, turn off the computer and transmitter. Power up the LongView Wireless transmitter unit, wait for the middle LED to illuminate, then power up the computer.

Retest the mouse and keyboard by connecting them directly to the computer and rebooting the computer. If one does not function correctly, replace the non-functioning peripheral.

Cycle power to the LongView Wireless 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 computer to verify that the monitor is working and that the computer is generating active video. If this is functioning, check that the display settings for your computer are set no higher than a resolution of 1024 x 768 at 60 Hz refresh rate. If the monitor does not function correctly, replace it.
