5.7.2. Reference Monitor
Reference Status: The Reference Status reports the current source of reference for the video path. If the
video path is currently locked to a reference signal, it will report the source of the reference signal as Card
ref, Frame ref 1, or Frame ref 2. If the card is actively locked to input video, it will report Video. If the video
path is currently free-running, it will report None.
Reference Type: The Reference Type reports the type of reference for the video path. If the video path is
currently locked to a reference signal, it will report the type of the reference signal as either Bi-phase or
Tri-level. If the card is actively locked to input video, it will report Video. If the video path is currently
free-running, it will report None.
Genlock Standard: External Genlock Standard reports the video standard of the detected reference
signal. If a signal has been detected, but the module determines the video standard, it will report
Unknown. If no reference signal is present on the selected reference input, it will report Not present.
5.7.3. Auto Reference Fail-over
Auto Reference Fail-over: The Auto Reference Fail Over Enable is used to set a Priority Genlock
sequence. When enabled the module will automatically fail-over to the next priority reference input
selected in the reference priority controls.
Priority Reference Select: This section allows the user to set the desired first, second and third priority
reference point.

Auto Reference Valid Timeout: This control sets a user specified time that the reference input return to
the Priority 1 reference when a valid genlock signal is re-asserted.
Auto Reference Invalid Timeout: This control allows the user to set a timeout length when a reference
signal is lost on the Priority 1 Reference input. Once the module confirms that, the genlock input is no
longer valid.
Auto Reference Status: The Auto reference Status Monitor is used to see what the current Priority the
module is under. It will report either Priority 1 or Priority 2 and the source of the current genlock input.
Auto Reference Reset Button: The Reference Reset Button allows the user to reset the Prioritized
Reference Fail Over back to original settings.
