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

 

There may be a delay skew issue. See Section on Skew

Problem:

Poor audio quality.

Solution:

Powered speakers are required. Make sure speaker power is ON

 

Check input source levels from the source device. Make sure the

 

audio source is not overdriven or underdriven.

channel, both audio inputs must be connected at the transmitter

 

end for full audio gain. Audio is line level

 

Serial//audio units support full stereo line level.
