3. Troubleshooting
1. Fuzzy, blurry, or ghosting image at remote location
If you have a stable image but it looks blurry (object or character edges
are smearing), adjust the compensation on the receiver. If you still have
a fuzzy image, try reducing the refresh rate and/or the resolution setting
of the video. For Best results use either low-skew cable (such as
Belden Brilliance® VideoTwist), or Cat5 (instead of Cat6).
2. Shaking image or periodically blanking monitor
A strong electromagnetic noise field can cause instability in the signal.
Usual sources of this form of noise coupling are high current AC lines
or other high-density data and/or control cables that run adjacent to and
parallel with a substantial length of the CAT5 cable.
To eliminate this, separate the Cat 5 cable of Mini-CAT5 Extender
from the interfering source or use shielded CAT5 cables. Usually
separating the CAT5 cable from the interfering source by a few inches
is sufficient to eliminate this problem.
If the length of Cat5 run exceeds 300 feet you may need an additional
power supply at the receiver.
