4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the MultiView™ CAT5 Video System can be
resolved by checking the CAT5 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’s 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 receiver EQ adjustment is set correctly — turn knob slowly.
• Make sure the CAT5 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.
• In some cases, the video termination may be mismatched. The
transmitters and receivers ship with 75-ohm termination as the
default. To disable termination, see
Appendix B
.
• There may be a DDC compatibility problem. See Appendix H.
Problem:
Poor video quality:
Solution: •
Have all receiver adjustments been finished ?
• Ensure EQ adjustment is set correctly — turn knob slowly.
• 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 in
receiver manual
• There may be a DDC compatibility problem. See Appendix H.
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.
• If Daisy Chaining, audio termination must be removed in DP
units. Only the last receiver requires termination. This does not
apply to SA or SAP units (SA units no longer require separate
daisy chain or end of line units as of April 2009). Reference
appropriate receiver user manual.
