NAV E 501 and NAV E 101 Encoders • Troubleshooting
69
Alarm
Cause
Remedy
Stream
Conflict
Multiple NAV endpoints are configured
to use the same video, audio, AES67, or
USB multicast IP address.
Reconfigure endpoint stream settings for
a unique stream address.
Stream
error
NAV E 501 only
— The encoder has
lost reception of the USB stream for
2 seconds or more.
Check all network switches and routers
that support your NAV system for proper
multicast (IGMP) configuration.
Temperature
Interna
l
The NAV device is overheating.
Check the ambient temperature of the
NAV device installation location.
•
If greater than 140 °F, (60 ºC) use
HVAC system to lower ambient
temperature.
•
If ambient temperature is
140 °F, (60 °C) or less, check
the mounting location for nearby
equipment emitting excessive heat.
Ensure there is an air gap around
NAVigator to allow adequate airflow.
Tie
Failure
The encoder failed to establish a tie with
the specified endpoint.
Debug the network connectivity between
the encoder and decoder.
Video
loss
The input is changed and video
sync cannot be established within a
two-second window.
Debug the connectivity of the A/V source
device to the NAV encoder.
