SW2 - Monitor Emulation Switches Factory Default Settings: 0000000000
These dip switches are normally exposed. Setting a switch to ON (1) affects a specific pin (or
pins) on the input connector for purposes of monitor emulation. Setting a switch to OFF (0)
passes the pin through the IN2022. If you don’t know what to do, set all dip switches to 0. See
pages 7 & 8 for detailed instructions.

The display device connected to the RGB output has a bad/scrambled image.
Solution 1: The display device connected to the output of the IN2022 may not be compatible with the computer
output. While VGA runs at 31.5 KHz, SVGA modes may run as high as 60 - 90 KHz! MACII type
computers have horizontal scan rates ranging from 24.48 to 68.9 KHz.
Solution 2: The output cable may have a bad sync line. Try running the sync through another cable.
Solution 3: The IN2022 output sync format may not be compatible with the display device.
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.
I have a PC and MAC connected to the IN2022 simultaneously and the image is scrambled.
Solution:
You may not connect both a PC and a MAC simultaneously! Connect one or the other.
The output image is missing a color.
Solution:
Possibly the output RGB 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.)
I’m using a 16” RGB monitor but my MAC is not booting up in the right video resolution
mode.
Solution:
The monitor emulation dip switches on the bottom of the IN2022 are probably forcing the computer into
the wrong mode. When using a local monitor, set all monitor emulation dip switches to 0 (see
page 7).
I’m using a laptop computer with the IN2022 and not getting any signal from the interface.
Solution:
You must set the IN2022 monitor emulation switches (page 7) and connect it to the laptop before
powering up the laptop. This tells the laptop to make the video port active.
