9084 Processing Error Troubleshooting
Table 3-5 provides 9084 processing troubleshooting information. If the 9084
card exhibits any of the symptoms listed in Table 3-5, follow the
troubleshooting instructions provided.
In the majority of cases, most errors are caused by simple errors where the
9084 is not appropriately set for the type of signal being received by the card.
Note: The error indications shown below are typical for the corresponding error con-
ditions listed. Other error indications not specified here may also be displayed
on DashBoard™ and/or the 9084 card edge status indicators.
Note: Where errors are displayed on both the 9084 card and network remote con-
trols, the respective indicators and displays are individually described in this
section.
Table 3-5 Troubleshooting Processing Errors by Symptom
Symptom Error/Condition Corrective Action
• DashBoard™ shows Video
yellow icon and Input Invalid
message in 9084 Card Info
pane.
• Card edge Input Format LEDs
show continuous cycling.
No video input present Make certain intended video source is
connected to appropriate 9084 card video input.
Make certain BNC cable connections between
frame Rear I/O Module for the card and signal
source are OK.
• DashBoard™ shows Frame
Sync red icon and Reference
Invalid message in 9084 Card
Info pane.
• Card edge red ERR indicator
illuminated.
Frame sync reference not
properly selected or not being
received • If external frame sync reference is not
intended to be used, make certain the
Framesync Enable selection list is set to Off
or Input Video as desired.
• If external frame sync reference is intended to
be used, make certain selected external
frame sync reference is active on frame sync
frame bus. (External reference signals
Reference 1 and Reference 2 are distributed
to the 9084 and other cards via a frame bus.)
Refer to Framesync function submenu tab on
page 3-15 for more information.
DashBoard™ shows
Framesync Status error
message in 9084 Framesync
function submenu screen. Specified Minimum Latency
Frames setting exceeds 9084
card buffer space for the
selected output video format • Reduce the Minimum Latency Frames setting
as specified in the error message to correct
the error.
Note: Due to card memory limits, the maximum
available Minimum Latency Frames is
related to the output video format.
For example, with a 1080i59.94 output, the
maximum allowed setting is 5. For a 1080i
film (23.98) output, the maximum allowed
setting is 3. Conversely, greater maximum
settings are allowed for SD formats such as
525i59.94, where the practical maximum
limit is 13.
