Installation, cont’d
Before installing an HSA 200 with an Extender line driver into furniture, test the system to make sure that the connections and settings are correct.
1.Apply power to the line driver. The power/signal LED on the line driver will light to indicate that the line driver is receiving power.
If the LED does not light, check the wiring at both the line driver and the power supply, and ensure that the power supply is connected to a power source.
If the image does not appear or there is no sound
1.Make sure that all the devices are powered on.
2.Ensure that the connectors are wired correctly at both ends of the cables. Audio cables must be wired for an unbalanced stereo input signal and for the appropriate (unbalanced or balanced) output signal.
3.If the input is from a laptop computer and no picture appears, use a laptop breakout cable for the input connection. Check the computer’s user’s guide or contact Extron to determine if special commands are required to output video to the external video port. Also, many laptops’ screens shut off after the external video port is activated.
4.Call the Extron S3 Sales and Technical Support Hotline if the image still does not appear or there is no sound.
If the image is not displayed correctly
1.If the picture is too bright or too dark, or if the edges of the image seem to exceed their boundaries, or if thin lines and sharp edges look thick and fuzzy, change the gain setting.
2.If the picture appears and is stable, but it has ghosting or blooming, verify that the video input is properly terminated. If the problem is not resolved by changing the termination, try using a different input cable. Poor quality or damaged cable can cause ghosting and blooming.
3.If the picture still is not displayed correctly, call the Extron S3 Sales and Technical Support Hotline.
