TROUBLESHOOTING
The display device connected to the RGBS output has a bad/scrambled image.
Solution 1: 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! MACII/Quadra computers sense what
monitor is connected and configure themselves accordingly, with horizontal scan rates
ranging from 24.48 to 68.9 KHz.
Solution 2: 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 2.
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.)
Output image is ghosting.
Solution:
The IN2080/81/90 are designed to plug directly into the computer’s graphic card and a short
(6 to 12 ft) monitor cable attached to the loop through output. An extension cable for the
input or a very long monitor cable may cause this problem.
The output image from an IN2080 is violet with a very low green signal.
Solution:
The local monitor may be monochrome. If it is a monochrome monitor, the IN9030 mono
adapter must be used - the output of the IN2080 will be black and white.
The output image from the IN2081 is too green.
Solution:
Some MACII and Quadra computers output an RGsBS signal. The Sync on Green Stripper
Level Control may need adjustment. Follow the adjustment procedure listed on page 4.
The output image from the IN2090 has horizontal black bars throughout the image.
Solution:
The Horizontal Blanking Control may need adjustment. First check the Horizontal Position
Control to ensure it is not causing the problem. If the problem persists, adjust the Horizontal
Blanking Control according to the procedure on page 5.
