4. Troubleshooting
4.1 Problem Solving FAQ
1. Fuzzy, blurry, or ghosting image at remote location
If you have a stable image but it looks somewhat blurry, make sure that
you have set the Receiver unit’s compensation pot correctly. Also
check table 3.1 to see that you have not exceeded the maximum cable
length recommendation. If you still have a fuzzy image, try reducing
the refresh rate and/or resolution of the PC.
2. Image exhibits steady or rolling horizontal color “hum” bars
This is usually an indication of improper grounding either at the
sending end, the receiving end, or both. Verify that the AC line is
properly wired and that a protective ground (green) wire is established
with NO potential difference between both the sender and Receiver
locations. The UTP Splitter can tolerate up to 5 v peak-to-peak ground
noise between the two locations, but no more.
3. Shaking image or periodically blanking monitor
Although CAT5 cable uses twisted pairs to transmit the signals from
the Splitter to the Receivers to reduce the amount of EMI coupled noise
from other external sources, 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,
either place a distance between the CAT5 cables from the Splitter and
the interfering source, or use STP shielded CAT5 cables.
4. The PC does not recognize a Plug-and-Play monitor
If the PC’s Operating System is setup to detect a plug-and-play monitor
(usually in Display Properties Advanced Settings), it may have trouble
finding a monitor if no local monitor is hooked up to the Splitter (at the
sending end). Only the ID information of the local monitor is passed to
