Troubleshooting
The display device connected to the IN3564HR / IN3566HR output has a bad / scrambled
image.
Solution 1: Verify that the correct input cable is being used.
Solution 2: The display device connected to the output of the interface may not be compatible
with the computer output. Standard 640 x 480 VGA runs at 31.5 KHz, but SVGA
can be as high as 48 - 58 KHz depending on the vertical refresh rate. Many
workstations have new 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.
The unit does not pass any signals.
Solution: The IN3564HR / IN3566HR contains two internal fuses. If power is applied to the
unit and none of the front panel LEDs activate, these fuses may be blown. Open the
case as described below and replace the blown fuses with new 200mA fuses.
1. Disconnect power to the switcher
2. Unscrew the two screws on each side of the unit
3. Gently slide off the top cover
4. Replace the bad fuse(s)
5. Replace the top cover and tighten the screws
