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 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.
• The NEC 600 only supports RGBHV video modes. Component,
composite or S-video is not supported. This is due to the design on
the option card slot interface and not the NEC 600 receiver.
Problem:
Poor video quality:
Solution: •
Have all receiver adjustments been finished (see section 3.3).
• 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.
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.
Problem:
Serial communication doesn’t work correctly.
Solution:
• Are the serial devices connected properly? Are the serial
parameters correct for source/destination devices?
• SAP units have a default baud rate of 9600 bps and use 3 wire
(TX,RX,GND) signals only.
• Please refer to the SAP Communication Protocol user manual for
information on using SAP series commands.
