4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the MultiView Series 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.
Reference the appropriate user manual for the transmitter and receiver in use for issues
specific to these units.
Problem: No video signal or poor video quality at the transmitter local port or
Solution: at the receiver.
• Check that all units are powered.
• Ensure EQ adjustment on receiver is set correctly.
• 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.
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.
• SA serial//audio units support full stereo line level. A high
frequency noise may be heard if the Cat5 cable from the
transmitter is disconnected, or the transmitter is not powered up.
This is normal and will disappear once a complete link
connection is made.
Problem: Serial communication doesn’t work correctly.
Solution: • Are the serial devices connected properly? Are the serial
parameters correct for source/destination devices?
• When using RS-232 transmitters or receivers in daisy chains,
Cat5 switches, 9D Cat5 distribution amps, or Multi-output
transmitters, the serial signal is a unidirectionally broadcast
mode only. In this mode, all other MultiView™ CAT5 Video
System devices must be the simplex serial type.
