Analog Composite I/O Installation

In Figure 5, the Analog Composite I/O board installed in slot J11 makes it the first
video board, going 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 will be connected.

c. If you then want to 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 video sources of the audio clocks for the Audio 1-Audio 4
banks of audio channels. You will have to remove any unused audio clock
cables and you may have to move boards around to accommodate your
desired system setup.
