30 Analog Composite Monitor Installation
In Figure 5, the Analog Composite I/O board installed in slot J11 makes it the first
video board, counting from J5 to J15, and the Serial Digital I/O board becomes the
second video board. You would have to move the Serial Digital I/O audio clock
cables from the ASPB Audio 1 and Audio 2 connectors to, respectively, the Audio
3 and Audio 4 connectors. Audio clock cable connections are then:
• Analog Composite I/O Channel A to ASPB Audio 1
• Analog Composite I/O Channel B to ASPB Audio 2
• Serial Digital I/O Channel 1 to ASPB Audio 3
• Serial Digital I/O Channel 2 to ASPB Audio 4
Bear in mind that the ASPB only provides for input of four audio clock signals
and note the following:
a. Figure 5 is an example of a 2-channel PDR200 with one Serial Digital
I/O board.
b. If you have a 4-channel PDR200 with two Serial Digital I/O boards, all
four ASPB audio clock inputs may be connected.
c. If all four ASPB clock inputs are connected and you then install an Analog
Composite I/O 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 your system up, that is, what you
want as the sources of the signals sychronizing the audio to the video. This is
primarily a software configuration function. However, how you configure the
audio clocks in software must match the physical connections but If you choose to
have the system clock as the synchronizing signalaudio clocks for the ASPB
Audio 1-Audio 4 banks. You will have to remove any unused clock cables and you
may have to move boards around to accommodate your setup.
Note that through Configuration Manager (see the Profile Family User Manual),
you may assign the source of audio clocks as either from the system clock or a
video source. If a video source is selected, you must then ensure that the audio
associated with that video source is connected to the correct audio channel
connectors.
