Each video input switch bank that has 129-256 camera
inputs (i.e., each switch bank that requires two card
cages) requires one
expander card in
the second card cage of each switch bank. Refer to
Section 2.4.2.1.2 and Figures 2-5 and 2-6 for a definition
and examples of switch banks.
Since a video input switch bank can accommodate 256
camera inputs, and each card cage can accommodate
128 camera inputs, there is never more than two card
cages in a switch bank. Therefore, there is never more
than one
in a card cage.
Two-position DIP switch U7 determines the address of
the
expander card. Refer to Figure A-5
for the location of DIP switch
Place the
card on a static-free work surface
before beginning work. Set both of the switches on U7
to OFF or “0.” All current
cards are
shipped in this configuration.
