Camera Input Connections

Camera connections to the LTC 8903 Series Input Bays require the LTC 8808/00 Video
Interconnect (Patch) Panel. Each patch panel provides 32 BNCs for video input or video
looping connections to the system. Patch panels are connected to the rear of the LTC 8903
Series Input Bay using the supplied LTC 8809/00 ribbon cables. Each cable can carry video for
up to 16 cameras. Two (2) cables can be attached to each patch panel to support up to 32
cameras per panel. Each ribbon cable should be attached to the appropriate VIDEO IN
connector on the rear of the LTC 8903 Series bays. A rear panel diagram of the LTC 8903
Series bay is shown in , page 66.
Refer to , page 66 for typical system connections.
The LTC 8809/00 ribbon cables have keyed connectors on each end. Maintain correct
polarity when attaching cables between system components.
Although attaching a ribbon cable with reversed polarity will not cause any permanent
damage, it can cause all video functions within the bay to cease until corrected. Double-
check ribbon cable connections to avoid this condition.
, page 66 illustrates the polarity key orientations on the LTC 8902 and LTC 8903 Series video
matrix bays.
The LTC 8808/00 panels are typically installed on the rear of the mounting rack behind the
applicable matrix bay. They can be mounted elsewhere as long as the 2 m (6 ft) LTC 8809/00
ribbon cables can reach the applicable matrix bay. Note, rack-mounting screws and associated
hardware are NOT included.
The Video Input connectors are labeled with multiple levels. If more than 256 cameras are
used in a system, multiple levels of input bays are used. This type of system configuration is
shown in , page 66 through , page 66.
6.12.2

System Connections over 1024 Cameras

If more than 1024 cameras are used, then a second stage of LTC 8903 Series Video Input Bays
are required. This type of system configurations is shown in , page 66, , page 66 through ,
page 66, , page 66, and , page 66. In this configuration, the VIDEO OUT connectors from
the first stage LTC 8903 Series bays are connected to the VIDEO IN connectors on the second
stage bays using LTC 8809/00 ribbon cables.
The LTC 8809/00 ribbon cables have keyed connectors on each end. Maintain correct
polarity when attaching between the bays. The VIDEO OUT connectors are labeled A
through D. These connectors must be connected to corresponding VIDEO IN connectors
labeled A through D.
6.12.3 System Connections over 1024 Cameras
The VIDEO OUT connectors from LTC 8903 Series input bays are connected to the VIDEO
BUSconnectors on the LTC 8902 Series output bays using LTC 8809/00 ribbon cables. Rear
panel diagrams of the LTC 8902 Series and LTC 8903 Series bays are shown in , page 66.
The LTC 8809/00 ribbon cables have keyed connectors on each end. Maintain correct polarity
when attaching between the bays. See , page 66, showing the polarity key of the ribbon
cable connectors located on the LTC 8902 Series and LTC 8903 Series matrix bays.
