Table 3-3 Troubleshooting Processing Errors by Symptom
Symptom Error/Condition Corrective Action
• DashBoard™ shows Video
yellow icon and Input Invalid
message in Card Info pane.
• If all inputs missing, card edge
Input Format LEDs show
continuous cycling.
No video input present Make certain intended video source is
connected to appropriate card video input.
Make certain BNC cable connections between
frame Rear I/O Module for the card and signal
source are OK.
• DashBoard™ shows invalid
in Ref Status message in Card
Info pane.
Reference not properly
selected or not being received
(card has reverted to free-run
failover) If external reference is not intended to be used,
make certain the Reference selection list is set
to appropriate alternate selection as desired.
• DashBoard™ shows Video
Input conflict in Video Path
Status message in Card Info
pane.
Incompatible combination of
SDI formats on SDI inputs A/B
or C/D Refer to Considerations Regarding
Multiple-Channel SDI (p. 3-8). If multiple inputs
SDI A/B or SDI C/D are used, inputs must
conform as described.
Audio embedded from external
MADI or AES sources show
errors or noise/pops. MADI audio not synchronous
with video MADI sources must be frame-referenced to
either the video being used or a reference. AES
audio is sample-rate converted to
accommodate minor timing variances.
Received SMPTE 337 (Dolby
® data) over an
AES input is automatically bypassed from the
sample rate converters; this data must be
synchronous to video.
DashBoard™ response slower
than normal. Too many PPM meters
activated Because the 9374-Series Input Meters and
Output Meters tabs display near real-time
dynamic data for many channels, network
traffic can be economized by disabling meters
when not being viewed (the meter transactions
occur whenever a meter tab is enabled,
regardless whether the page is being
displayed).
Use the meter Timeout or Enable/Disable
controls to turn off metering not being used.
Input Meters or Output Meters do
not display channels as
expected. Input Meters and Output
Meters not enabled or have
timed out Make certain intended Input Meters and/or
Output Meters are enabled, with Display
Status showing “Meters are currently
displaying”.
Dolby ® data outputted on card
SDI, AES, or MADI channels not
recognized or decodable as
Dolby.
Gain controls set for other than
unity If channel(s) are carrying Dolby ® data, make
certain Gain controls are set at default unity
setting. Applying any gain change to a Dolby
stream will corrupt the data.
