TROUBLESHOOTING
The display device connected to the IN2000 RGBS output has a bad/scrambled image.
Solution 1: Verify that the correct IN5100 Series input cable is being used.
Solution 2: The display device connected to the output of the interface may not be compatible with the
computer output. CGA and EGA signals vary from 15.75 to 24 KHz. VGA runs at
31.5 KHz, but SVGA can be as high as 48 - 58 KHz with newer modes such as 1600 x 1200
running at 79 KHz! MACII/Quadra computers sense which monitor is connected and
configure themselves accordingly, with horizontal scan rates ranging from 24.48 to 68.9
KHz.
Solution 3: Check the dip switch settings to make sure the unit is putting out a sync format that the
display device can use. For most applications the default dip switch settings (see Page 9)
will work best.
Solution 4: The RGBS cable may have a bad sync line. Try running the sync through another cable.
The output image is very dark.
Solution: The horizontal position control may be set off to an extreme position or may be interacting
poorly with the horizontal position control on the display device. Follow the horizontal
position adjustment procedure listed on Page 6.
The output image is missing a color.
Solution: Possibly the RGBS cable is bad. Try switching connections on the output to verify that the
bad color’s cable is OK (Example: If there is no red, try running the green output through
the red cable and see if green is displayed or not.)
