Troubleshooting


Problem: The display device connected to the RGB output has a bad/scrambled image.

ΠSolution 1: The display device connected to the output of the IN2022HR may not be

compatible with the computer output. Many PCs and MACs have new and ultra high-
resolution modes such as 1600 x 1200 and 1800 x 1440, and can output a video signal with a
horizontal scan rate of over 100 KHz! Many data monitors and data projectors are not
compatible with these resolutions and frequencies.

ΠSolution 2: The output cable may have a bad sync line. Try running the sync through

another cable.

ΠSolution 3: The IN2022HR output sync format may not be compatible with the display

device. Check the documentation for both the computer graphics card and the data display
device to ensure compatibility.

ΠSolution 4: You may not connect both a PC and a MAC to the IN2022HR

simultaneously! Connect one or the other.


Problem: The power switch is turned on, but the front panel POWER LED is dark.

ΠSolution 1: Make sure that the IN9230 IEC power cable is securely plugged into the unit and

the A/C source.

ΠSolution 2: Make sure the A/C source is live.

ΠSolution 3: The IN2022HR contains a time delay fuse. To change the fuse, disconnect the

IN9230 IEC power cable and slide out the fuse holder (located on the rear panel to the left of
the IEC cable receptacle) using the IN9339 INLINE adjustment tool.

Problem: The output image is very dark.

ΠSolution: The horizontal position control may be set to an extreme position or may be

interacting poorly with the horizontal position control on the display device. Follow the
horizontal position adjustment procedure on page 5.


Problem: The output image is missing a color.

ΠSolution: The output RGB cable may be 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.)


Problem: The MAC connected to the IN2022HR is not booting up in the right resolution mode.

ΠSolution: The monitor emulation dipswitches on the bottom of the IN2022HR are

probably forcing the computer into the wrong mode. When using a local monitor, set all
monitor emulation dipswitches to 0.
