Enhanced Disk Recorder Installation

If all four ASPB clock inputs are connected and you then install another video
board, you will have more audio clock signals than you have connections on the
ASPB (two from the Analog Composite I/O board and four from the two Serial
Digital I/O boards).

You will have to determine how you want to set up your system; that is, what you want
to use as the signal sources that synchronize the audio to the video. While this is
primarily a software configuration function, keep in mind that how you configure the
audio clocks in software must match the physical connections.

NOTE: The Configuration Manager (see the Profile Family User Manual) allows
you to assign either the system clock or a video source as the source of audio clocks.
If you select a video source, then you must ensure that the audio associated with that
video source is connected to the correct audio channel connectors.
