Troubleshooting

Problem: There is no image on the monitor / display device.

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

and the A/C source.

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

Solution 3: Verify that the power switch is turned on for the video source, the

IN2200RS and the monitor.

Solution 4: Verify the connection to the output display device.

Problem: The display device connected to the IN2200RS 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. PC, MAC, SUN and other high-resolution work-
stations 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.

Solution 2: Check the dipswitch settings to make sure the unit is outputting a sync

format that the display device can use. For most applications the default dipswitch
settings will work best (see page 10).

Solution 3: The output cable may have a bad sync line. Try running the sync through

another cable.

Problem: The local monitor looks fine but the image on the Data Projector / Data Display

is wavy or has vertical bars in the picture.

Solution 1: LCD / DMD displays work best when the sync signal has minimum sync

processing. Set the interface dipswitches as indicated in the Optimal Settings for LCD /
DMD / D-ILA / Plasma Displays Section on page 11. Setting the interface to RGBHV
output and disabling the horizontal position control may alleviate this problem.

Solution 2: LCD / DMD displays often have an adjustment called Phase Adjust or Fine

Phase Control. This control should be adjusted to provide the best image.

Problem: The output image is too green.

Solution: The dipswitches may be set for Sync on Green output. Try changing the

dipswitches to factory default so the unit outputs an RGBHV signal (see page 10).
