5 Solutions to Common Problems
In most cases, nearly every issue with the Cobra series can be resolved by
checking the CAT 5 termination and making sure that it’s pinned to the
TIA/EIA 568B wiring specification. However, there may be other problems
that cause the system to not perform as it is designed. Below are solutions to
the most common installation errors.
Problem:
No video signal at the transmitter local port or at the receiver.
Solution:
Check that both units are powered.
Ensure EQ adjustment is set correctly — turn knob slowly. • Make
sure the CAT 5 cable is terminated correctly per the TIA/EIA
568B wiring specification.
Is the display device powered on and functioning?
Check to ensure display settings (resolution, refresh rate, etc) are
compatible with input signal.
Problem:
Poor video quality.
Solution:
Have all receiver adjustments been finished?
Ensure EQ adjustment switches are set correctly
Check all cable connections
The video signal’s refresh rate may be set too high. Reset to a
lower refresh rate in your monitor-configuration menu
