4.1Video

The image is not sharp, or is badly smeared.

Check that the cable length DIP switch is correct for the length of your Interconnect cable (see page 18).

Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 17)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly?

Ensure that all video connections throughout the system are attached securely.

Are you using an LCD panel? You must adjust its clock and/or phase either manually or using auto-adjust.

Colors appear to be separated and there are colored borders on text and icons.

Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 17)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly?

Are you using low skew cable? You can test for skew by viewing the online test card at: http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html

I only need video extension – not USB - but I can’t get a picture.

Have you powered the Local unit? The Local unit gets its power from the CPU through the USB connection and it will not operate without it. Use an external 5V PSU as described on page 21.

The monitor sometimes goes blank for a second or two.

Check that the interconnect cable is not routed near power lines or other sources of electrical interference. Use shielded STP/FTP cable instead of UTP cable and ensure the shield connection is maintained between the Extender units.

Check system grounding.

If this is a persistent problem, contact Technical Support.

Jitter is evident on video.

Adjust the clock and/or phase on your flat-panel. Contact Technical Support if this fails to improve the situation.

Are you testing a system using a coiled drum of CATx cable? Try uncoiling the cable. If this solves the video jitter, you should not have a problem after full installation.
