The Watch Dog is a feature that allows the system to continue video passthrough on a
Vertigo hardware device during an application crash or a system failure. The Watch Dog
page is a sub-page of the Hardware Settings tab, which is only visible when a Vertigo
hardware device is selected in the Dashboard’s device list. Use the settings below to
configure the Vertigo device’s Watch Dog.
N OTE
The Watch Dog field on the Vertigo device console uses a colored LED along with a brief
statement to indicate the Watch Dog’s current state during operation (see
page 3-3 ).

M ODE • B YPASS WITH OPAQUE KEY : The Watch Dog is enabled and when it activates
the key signal will become opaque.
• B YPASS WITH TRANSPARENT KEY : The Watch Dog is enabled and when it
activates the key signal will become transparent.
• D ISABLED : The Watchdog is not active. If the device fails, the output will
most likely be frozen on the last frame produced.
• I GNORE : When the setting is I GNORE , the device sends no signal to the
hardware and the device does not use the Watch Dog. The hardware will
therefore be in the last state it was set to. If however, the last state of the
hardware had the Watch Dog enable, the device will NOT send a regular
signal and you might never see the frames being rendered by the device.
Therefore, we recommend that you intentional set the F
ILL to E NABLED
when you want activate the Watch Dog.
T IME O UT Specifies the number of milliseconds that must elapse during which no rendering
occurs before the hardware Watch Dog kicks in. The default value is 500.
M ONITOR GPI When enabled, the watch dog listens to the GPI server for a trigger to activate
the video bypass functionality.
