IN3264 / IN3268 OPERATION MANUAL - REV. 1.3 01/04/01 ©1999 INLINE, INC.
Troubleshooting
The display device connected to the IN3264 / IN3268 output has a bad / scrambled image.
Solution 1: The display device connected to the output of the distribution amplifier may not be compatible
with the computer output. Many older LCD and Data Display units will not present signals
at resolutions higher than 640 x 480 or 800 x 600, or horizontal scan rates above 36 KHz or
48KHz. Make sure you know what resolution mode the computer video card is set to output.
While basic 640 x 480 VGA at 60 Hz refresh rate runs at 31.5 KHz, SVGA modes can be as
high as 48 - 58 KHz with the highest resolution settings such as 1600 x 1200 running at 80
KHz or higher depending on the refresh rate setting. Sun and SGI computers usually operate at
61KHz, 64KHz, or 71KHz at resolutions as high as 1280 x 1024.
Solution 2: The output cable may have a bad sync line. Try another cable.
The output image is missing a color.
Solution: The output cable may be bad. Check both ends of the cord to see if any of the pins are bent or
missing. Also inspect the cable to see if the coax may have been pinched or severed internally.
Try another cable.
The output image of the IN3264 / IN3268 is visible but has poor quality / low definition.
Solution: The output cables may be too long or of poor quality. INLINE offers several high-resolution
mini-coax cables for analog signals and a series of shielded twisted pair cables designed
specifically for digital video signal transmission. See page 7 for specific recommendations.
The unit doesn’t output any signal and the power light is not turning on.
Solution: The power adapter may have failed. It should feel warm to the touch after it has been plugged
in for a few minutes. If the adapter feels cool, replace it.
