1. To adjust individual colors, press and hold briefly, and then release the
EQ/Skew knob until the desired color LED is flashing for the R/G/B
LED. The LED color corresponds to the color channel being adjusted.
2. Using the image utility, turn knob to add/subtract delay timing until a
single vertically aligned line of red, green, blue is obtained.
3. When complete, press and hold briefly, and then release the EQ/Skew
knob until the R/G/B LED is solid green.
Not all colors will have the same delay settings.
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.
Audio is summed left and right for “A” versions. If using a single
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. A high frequency
noise may be heard if the CAT 5 cable from the transmitter is
disconnected, or the transmitter is not on. This is normal and will
disappear once a complete link connection is made. Units do not
exhibit this behavior
