2.3.1 CARD CAGE INSTALLATION
NOTE:
It is recommended that two installers
work
together to mount the card cages in the rack.
Some rack manufacturers supply special mounting
hardware. Determine how this hardware is to be used
before attempting to install any racked equipment. One
installer should position the rack while a second installer
secures it to the front standard.
2.4 System Cabling
This section provides information on the cabling re-
quired to connect the system components. Refer to page
l-3 for Coaxial Cable Recommendations.
When installing the
or
ca-
ble assemblies, orient the connector so that the locking
lever locks into the notch on the right side on the
connector on the panel,
NOTE: When using these cable assemblies with
older connector panels, cut off the locking lever for
proper fit.
NOTE: Words in capital letters (e.g., PWR or
CONTROL OUT) indicate the names used on the
card cage panels.
2.4.1 COAXIAL CABLE CONNECTIONS
BETWEEN CAMERAS AND SWITCHER
CARD CAGES
Camera inputs are connected to the input BNC connec-
tors on the video switcher subpanels on the rear panel
of the card cage. Refer to Figure 2-2. The individual
video switcher subpanels are numbered 1-8, 9-16,
and so on. The BNC connectors are used
for video input. The ribbon cable connectors are used to
loop video out to additional card cages. The lowest
number camera is connected to the top BNC on each
subpanel. For instance, camera 1 should be connected
to the top BNC connector on panel l-8. Camera 8 should
be connected to the bottom BNC connector on
1-8, and so on.
If there are no more than eight monitor outputs in the
system, terminate all the looping video output ribbon cable
connectors with the
ribbon cable terminators.
2.4.1.1 Monitor Expansion
NOTE:
Section
(Monitor Expansion) and
Section 2.4.2.1 (Camera Expansion), the interconnec-
tions between the card cages may be made with indi-
vidual coaxial cables terminated with BNC connectors
or
with coaxial ribbon cables terminated with coaxial
ribbon cable connectors. In order to keep
as
clear
as
possible, the figures referenced in these sec-
tions show card cage interconnections made with rib-
bon cables. Model
is a
coaxial
ribbon cable assembly used for distributing video be-
tween V441 OS-HD switcher cards. Longer ribbon ca-
bles are available on special order.
NOTE: Model
is a
coaxial
ribbon cable assembly for distributing video signals
from the
switcher cards to external
devices. The
ribbon cable assembly is
terminated with eight BNC connectors. This cable as-
sembly may be used as necessary in Sections 2.4.1 and
2.4.2.
If there are 9 to 16 monitor outputs, the system requires
a second card cage for monitor expansion. The video
switcher subpanels in the second card cage may contain
two ribbon cable connectors or one ribbon cable con-
nector and eight BNC connectors to loop out to external
devices. Connect a ribbon cable from the looping out
ribbon cable connectors on card cage 1 subpanels to one
of the ribbon cable connectors on card cage 2. See
Figure 2-2. If there are no more than 16 monitors, the
other ribbon cable connector or unused BNC connectors
on the second cage must be terminated.
If the system has 17 or more monitor outputs, it is
necessary to loop to another switcher card cage. Install
looping ribbon cables or coaxial cables terminated with
BNC connectors from card cage 1 to 2, from 2 to 3, and
so on until the last card cage is connected. Terminate
the unused video ribbon cable connectors or unused
BNC connectors on the last card cage.
