Configuration
Test Output
An internally generated colorbars test signal may be enabled on the output
of the module by checking the
Enabled
checkbox. Be sure to disable this
output before going on-air.
Output Timing
Select the Primary and Secondary output timing source for the module as
either
Local
(external reference from the 8900GEN-SM submodule mounted
on this module),
Ref Bus 1
(8900GEN-SM submodule is mounted on module
in slot 1 and jumpered for outputting a Ref 1 frame bus),
Ref Bus 2
(8900GEN-SM submodule is mounted on module in slot 3 and jumpered
for outputting a Ref 2 frame bus), or
Input
, the reference is taken from the
input video. The signal and genlock status of each reference source will be
reported in the Status and Genlock columns.
When a Secondary reference source is selected that is different than the Pri-
mary, the module can be configured to switch automatically to the Sec-
ondary selected if the Primary is lost or becomes unlocked or invalid. If you
do not want this action of switching to a secondary, set the Primary and Sec-
ondary sources to the same source or set the Switch to Primary control
below to
Manual
.
Refer to 8000GEN-SM Reference Timing
for an overview of using
the 8900GEN-SM submodule for reference timing. Also refer to the
8900GEN-SM Installation Manual available online for complete details for
using this submodule for timing applications.
Reference Restore
If the Primary source has failed and a Secondary source is selected and
valid, the following controls allow you to set the module to switch back to
the Primary automatically or manually and determine the amount of time
before the Primary is restored.
•
Switch to Primary
– set this control to
Manual
if you wish to manually
return to the Primary reference when it becomes valid or locked again
or
Auto
to allow the module to switch back to the Primary reference.
•
Reference Switchback Delay
– when the control above is set for
Auto
, set the
amount of time to allow between switching from the Secondary refer-
ence back to the restored Primary. The switchback time has a minimum
recovery time of 30 seconds to assure that the Primary is locked and
valid before the module switches back to this source.
