Configuring the Genlock Submodule
Genlock Web Page
The Genlock web page ( Figure 3 on page 15 ) provides reporting status for
the following genlock status items:
• Genlock – reports status of Genlock function as Enabled or Freerun .
• Status – reports whether the reference input is Locked or Invalid .
• Firmware Version – reports the firmware version of the 8900GEN-SM
submodule installed on this host module.
• Hardware Version – reports the hardware version of the 8900GEN-SM
submodule installed on this host module. (See
Figure 4 on page 16 if a
hardware message appears on the Genlock web page.
• Ref Input Standard – reports the reference input standard detected by
the 8900GEN-SM submodule that is connected to the Genlock Loop on
the host rear module.
• Ref Input Frame Rate – reports the frame rate of the reference input as
detected by the submodule.
• Output Bus Frame Rate – reports the frame rate being output on the
frame bus.
• Output Bus – reports the reference bus (Ref Bus 1 or Ref Bus 2) being
output from the submodule.
Genlock Control
The following controls are available for configuring the Genlock sub-
module:
• Enable or Freerun – select one of the radio buttons to enable the Genlock
submodule or allow the reference to freerun.
• Input Standard Selection – use this control to set the input standard needed
for the reference input. Refer to Table 1 on page 9 for compatible rates.
• Loop Bandwidth – set this control for either fast locking ( Fast Lock ) to the
reference or for the lowest jitter performance ( Low Jitter ) depending on
the stability of the reference signal being used. For example, if Low
Jitter is selected and the Status is still
Invalid after one minute has passed,
the input reference has excessive wander that cannot be tracked in Low
Jitter mode. Switch to
Fast Lock and verify Status is Locked after about 10
seconds
