IN2013HR Operation Manual - V1.0 12/05/00

Problem: The display device connected to the IN2013HR output has a bad / scrambled
image.

Solution 1: Check the dipswitch settings to make sure the unit is outputting a sync

format that is compatible with the display device. For most applications the default
dipswitch settings will work best (see page 7).

Solution 2: The RGB cable may have a bad sync line. 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.)

Solution 3: The display device connected to the IN2013HR may not be compatible with

the computer output. Adjust the output resolution of the computer video card
accordingly.

Problem: The output image is very dark.

Solution: 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 6.

Problem: The output image is missing a color.

Solution: The RGB cable may be damaged / defective. 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 output image is very bright and appears “overdriven” with poor contrast.

Solution 1: Verify the gain setting on the IN2013HR. If it is set to a very high level,

reduce the gain control setting as required.

Solution 2: Check the contrast and brightness settings on the display device. Many

display devices look best with the contrast set toward the upper end of the adjustment
range (75 - 95%) and the brightness set towards the middle of the adjustment range (40 -
60%).

Problem: The output image is green.

Solution: The dipswitches may be set for Sync on Green output. Not all data displays

operate well with an RGsB signal. Try changing the dipswitches to factory default so the
unit outputs an RGBHV signal (see page 7).

Problem: The output image is doubled, with two images displayed side-by-side.

Solution: The display device may not be compatible with the horizontal scan rate of the

computer.
