The System Riser Diagram and/or schematics found in either Appendix B of this manual or in
the System Overview manual, if present, will illustrate which column directors within the display
receive signal from which data distributor outputs. Remember, each output card has two outputs.
Figure 34 labels the A outputs of a 10 output card data distributor. Ten is the maximum number of
output cards the data distributor can accommodate. This display may have two, four, six, eight or
ten output cards.
Column directors within the display receive signal from the output cards in the data distributor. The
signal is then routed from the column directors to the line controllers.
Figure 35 shows the input and output jacks on a column director.
Line controllers receive signal from the column directors and send it to the modules in a given row
and to the line controller in the next row below it. Figure 36 shows the input and output jacks on a
line controller.
