APPENDIX B
B. MATRIX 44 CARD CAGE REMOTE VIDEO SWITCHER
COMPONENTS
The
Control and Remote Video Switching
System includes at least one Matrix 44 high-density
card cage located at each remote site. The inputs from
each of the remote sites are combined onto eight
monitor outputs and routed via coaxial cable to a
Matrix 44 card cage located at the terminal site.
One Matrix 44 card cage (containing one
and 16
video
switcher cards) at each remote site will support up to
128 camera inputs and eight monitor outputs.
In a system with more than one card cage at any remote
site, one card cage, the master, houses the model
CPU. Each slave card cage is sup-
plied with a
address decoder card in
place of the V
The following components can may be used in the
Matrix 44 card cages:
Card cage. Each system has
at least one card cage located
at each remote video switch-
ing site and at the terminal
site. It includes its own
power supply, a mother
board, and a video amplifier
board.

Switcher card. Accommo-
dates up to eight video inputs
per card. The card cage
accommodates up to 16
cards, for a
capacity of 128 video inputs
by 8 monitor outputs.
Address decoder card is
used
p l a c e o f
in all
slave card cages. It is used
to define the video output
(monitor) addresses.
Expander card is used when
the number of camera inputs
at a remote site exceeds 128,
requiring an additional card
cage or cages.
he card arrangement for a 128
remote video switching site. A
remote site with fewer camera inputs
have fewer
switcher cards, depending on the number
of video inputs. For instance, a
remote
site will require only 13
cards
(104 cameras/8 cameras per card), leaving three empty
card slots.
Addressing Matrix 44 Switcher Components

Switching Systems with the matrix switching
addresses correctly set. However, when expanding a
system or replacing an existing card, the addresses
must be set properly.
The addresses of the Matrix 44 cards
switcher card,
card, and
expander card) define video signal
inputs and outputs for the system. Additional cards
must have their addresses set before installation in a
card cage.
Video input (camera) addresses are set on the
switcher cards. The video input address
permits the system to select a specific video input.
Video output (monitor) addresses are set on the
address decoder cards. The video
output address permits the system to specify to which
monitor (or other output device) a selected camera
input will be routed. In a single-card-cage remote site,
the video outputs
automatically identified as l-8.
and no addressing is required.
