Video

The image is not sharp, or is badly smeared.

Have you adjusted the video equalization? Refer to the manual supplied

with your Remote Unit.

Check the Interconnect cable between the Remote and Local Units. Is it

of the recommended type (see page 12)? Is it intact along its entire

length and securely connected at both ends? Is it wired correctly (see

page 12)?

Ensure that all video connections throughout the system are attached

securely.

Are you using an LCD panel? You need to adjust its clock and/or phase.

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

icons.

Have you adjusted the skew compensation? Refer to the manual

supplied with your Remote Unit for details of skew adjustment and

reduction techniques.

Check the Interconnect cable between the Remote and Local Units. Is it

of the recommended type (see page 12)? Is it intact along its entire

length and securely connected at both ends? Is it wired correctly (see

page 12)?

Are you using low skew cable?

I only need video extension – not keyboard or mouse - but I can’t get a

picture

Have you powered the Local Hub? Each Local Hub port gets its power

from the CPU through the keyboard connection and it will not operate

without it. Use the external 5V PSU as described on page 17.

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 ensuring that the shield connection is maintained between

the Extender Units.

Check system grounding. If your remote monitor has an external PSU

you may need to consider grounding the Remote Unit chassis (to power

ground).

If this is a persistent problem, contact Technical Support.
