INSTALLATION GUIDE 3 of 64
Connections
•Set jumpers in plug-in modules before making
system connections.
•System connections require good grade, 75-ohm,
RG-59U video cable (Belden 8241 or equivalent)
with BNC connectors. Complete all connections
before applying power.
•Terminate all video outputs at the last bay in the
run to 75 ohms. An un-terminated run results in a
brighter picture than desired. A double terminated
run results in a darker picture than desired.
•To facilitate servicing, identify all connecting
cables with source/destination numbers.
General
•Perform each installation in a planned and orderly
manner.
CAUTION: Each bay uses plug-in VIMs
(video input modules) and VOMs (video
output modules). Although VIMs and
VOMs can plug into any slot of a bay
and still work (as long as they are
properly configured), it is important to
plug all VIMs in series “starting from the
right-most slot” and all VOMs in series
“starting from the left-most slot”. If this is
not done, future expansion and
troubleshooting will be difficult.
•Confirm that each piece of equipment operates as
early as possible during the installation procedure.
It is easier to remove a few temporary
connections than it is to disconnect and re-wire a
large number of permanent connections.
Powering Up the System
Bring the system online only after:
•The CPU has been installed and connected
•Video input has been connected
•At least one monitor has been connected for
viewing the output
•All lines are properly terminated
•At least one keyboard (or external computer) has
been connected for control
•Power has been connected to the equipment, one
bay at a time, ending with the CPU.
Glossary of Terms
Terms used in this guide are as follows:
Matrix Switching Bay = A device that can switch a large
number of video inputs such as cameras to multiple video
outputs that connect to a device such as a monitor, DVR,
or VCR.
VIM = Video input module (each VIM supports up to 16
video inputs). Up to 16 VIMs can plug into a bay but its
number may be limited by the amount of VOMs in the bay.
VOM = Video output module (each VOM supports up to 4
video output devices). Up to 16 VOMs can plug into a bay
but its number may be limited by the amount of VIMs in the
bay.
Camera Group = Each matrix switching bay supports a
camera group of up to 256 video inputs: camera group 1
(1-256 inputs), camera group 2 (257-512 inputs), camera
group 3 (513-768 inputs), and so on.
Monitor Level = A monitor level is up to 16 video outputs
supported by one or more bays: monitor level 1 (1 -16
outputs), level 2 (17-32 outputs), level 3 (33-48 outputs),
and so on. Video outputs can be in one or more bays.
ADDL (AD Data Line) = One data line controls up to four
monitor levels (or 64 video outputs). Four data lines control
up to 16 monitor levels (or 256 video outputs).
Data Buffer = Amplifies video and filters data before
sending it to a video output device.
Camera Group Symbol Definitions: The symbols
on the rear panel of the switching bay identify a camera
group (Table 1).
