Troubleshooting
When the interface, computer and output devices have been properly installed, and the power is turned on, the image should appear on screen, and sound should be audible.
If the image does not appear or there is no sound
1.Ensure that all devices are plugged in.
2.Make sure that each device is receiving power. The power indicator LED should light if the interface is powered on.
3.Check the cabling and the audio connector wiring, and make adjustments as needed.
4.Verify that the video input termination DIP switch on the RGB 138xi and the ID bit termination DIP switches on the RGB 158xi have been set correctly.
5.For digital display devices, try switching between ADSP and DDSP using the rear panel DDSP DIP switch.
6.Call Extron’s customer support hotline if needed.
If the image does not display correctly
1.If the output image looks too green, make sure that the sync on green feature (SOG DIP switch) is turned off.
2.If the picture bends or flags at the top of the screen, set the SERR (serration pulse) DIP switch to Off.
3.For a display device that experiences intermittent glitches, try switching between ADSP and DDSP using the rear panel DDSP DIP switch.
4.If the picture “hangs off” the edges of the screen, adjust the centering controls.
5.If the edges of the image seem to exceed their boundaries or if thin lines and sharp edges look thick and fuzzy, try changing the GAIN/PEAK setting.
6.If the image still does not display correctly, call Extron’s customer support hotline.
