Figure 5.7: Typical Video Input Module Insertion
All LTC 8921/00 Video Input Modules are identical and can be swapped anywhere within the
bay without making any changes to the module except to maintain proper termination
settings.
System Video Connections
Camera Input Connections
Camera connections to the LTC 8903 Series Input Bays require 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 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 68. Refer to , page 68 to , page 68 to review typical system
connections.
The LTC 8809/00 ribbon cables have keyed connectors on each end. Maintain correct
polarity when connecting system components.
Although attaching a ribbon cable with reversed polarity will not cause 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 68 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 that rackmounting 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. These system configurations are
shown in , page 68 through , page 68.
System Connections over 1024 Cameras
If more than 1024 cameras are used, a second stage of LTC 8903 Series Video Input Bays are
required. These system configurations are shown in , page 68, , page 68 to , page 68, ,
page 68 and , page 68. 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.
