Derived References
(Nucleus2 only)
This screen displays the status of the external references, offsets and derived references.
See the on screen Key for details.
Derived video references enable the router to use a reference signal standard that is not
available from outside of the router frame as if it is a standard physical video reference input.
Video reference signals are derived (created) from the BNC video reference inputs on the
rear of the router. These derived video references can be at a higher or lower resolution than
the signal on the BNC reference input but they must share the same frame rate as the original
reference signal they are created from. For further details on derived video references see
section 3.11.
The pictorial status screen displays the video standard of each of the external BNC reference
inputs. The screen also shows whether the external references are passed straight to one of
the four internal references or are used to create one or more derived references. Any of the
references can have an offset applied if required. The audio reference input status is also
displayed.
Touch the Configure References button to make configuration changes to the video
references (see Figure 33).
Alternatively references can be configured from Workbench and pushed to the controllers,
see the Workbench manual for information. For details on configuring the audio reference see
section 3.12.
Note:
If the Configure References button is not displayed on the door screen it is not possible to
configure the references from the door screen. This will be the case when the screen has
been edited by the system administrator to stop references being modified from the router
door screen.
