u Modular construction
The LTC 8900 Series Allegiant Video Switcher/Control
Systems are powerful full matrix switchers, capable of
displaying video from any camera on any monitor,
either manually or via independent automatic
switching sequences. By using the LTC 8901 Series
CPU and the LTC 8943 series PC, the standard system
can be enhanced to include dual/redundant CPU/
Power supply with automatic hot-switchover
capabilities.
Functions
General Construction
The LTC 8900 Series provides versatile modular
construction accommodating up to 4096 camera
inputs, 512 monitor outputs, 120 keyboards, 1024
alarm points, and a computer interface port. The
robust design utilizes a separate CPU bay with its own
power supply.
Dual/Redundant System
For situations where complete system failure cannot
be tolerated, we offer the dual redundant LTC 8901
CPU. This CPU unit incorporates a secondary CPU/
power supply. In the event of a primary CPU or power

supply failure, the system switches over automatically
to the backup CPU or power supply. The system uses
an independent PC that continuously monitors the
CPUs for failure and performs a hot-switchover if
needed. You can also manually change CPUs using the
preloaded software or via a front panel slide switch.
Sequencing Capabilities
These systems can be programmed with up to 256
sequences, which can be run independently of each
other in either a forward or reverse direction. Any of
the sequences can utilize the SalvoSwitching
capability, where any number of system monitors may
be selected to switch as a group. Using the supplied
software, sequences can automatically activate and
deactivate based upon the day or the time of day.
Camera Control
The LTC 8900 Series support variable speed operation
and full programming access for AutoDome and
AutoDome Easy II Series cameras. In addition, on-site
receiver/drivers are available to provide operator
control of pan, tilt, zoom, pre-positions, auxiliaries,
2 | LTC 8900 Series Allegiant Matrix/Control Systems - Modular
auto-pan, and random scan functions when used with
conventional pan/tilt devices. An integral local test
function is also a standard feature.
The LTC 8900 Series include an impressive user-based
priority system and a series of programmable lockout
tables to limit operator access of remotely controlled
devices. Operators can restrict control from lower
priority operators either manually or automatically.
When enabled to operate automatically, a built-in timeout period is user programmable.
Bilinx Capability
When combined with an LTC 8016 Allegiant Bilinx Data
Interface unit, these switcher/controllers support
operations using Bilinx communication. With Bilinx,
PTZ control is accomplished using a bidirectional
communication protocol embedded in the video signal
of Bosch Dinion®, AutoDome, and AutoDome Easy II
CCTV cameras. In addition, Bilinx uses the standard
video cable to transmit alarm and status messages
from the cameras, providing superior performance
without the need for separate data transmission
cables.
Macro Capabilities
The LTC 8900 system provides powerful macro
capabilities. Macros can be activated using Allegiant
Series system keyboards, timed event functions, and
alarm activations.
Alarm Capabilities
The LTC 8540/00 alarm interface unit allows external
contact closure or logic level input to automatically
display cameras on a monitor or group of monitors.
The supplied PC software includes the ability to
combine multiple alarm operating modes within the
same system. Alarm video may be selected to reset
either manually or automatically. In addition, one can
customize a 16-character alarm titles to designate the
specific alarm condition.
System Operation
System operation and programming is accomplished
using a full-function, ergonomically designed keyboard.
Up to 120 keyboards may be used in the system. Builtin operator priority levels and the ability to restrict
certain operators from controlling designated
functions provide maximum flexibility.
Programming/Software Capabilities
The LTC 8900 Series includes a black outlined 48character on-screen display for time/date, camera
number, camera ID (16 or 40 characters), and monitor
(12 characters) or status information. A user
selectable option provides the ability to display a third
line of on-screen text. This third line can be configured
to display up to 24 additional camera title characters
(40 characters total) or a 12-character monitor title.
The on-screen display is also user selectable to
operate in "6-digit Camera ID" mode. When enabled, 2digit "site numbers" are displayed in addition to the 4digit camera number. The 2-digit site number feature
is especially useful when groups of cameras are
located in separate buildings, floors, or other common
areas.
Over 1,000 characters covering a multitude of
languages, (including several hundred Chinese
symbols) are available to help program camera ID and
monitor titles. Using the supplied PC software,
enhanced programming and switching features can be
obtained. A user friendly spreadsheet format allows
one to easily enter/change camera titles, operator
names, timed events (128), system parameters,
camera sequences, lockouts, and advanced alarm
response programming. The software also provides the
ability to enable an on-screen indicator for easy
identification of controllable cameras. Another useful
feature of the software is its ability to store or print (in
real-time) programming information, system events,
alarms, switching functions, sequence events,
keyboard actions, and video loss information.
Expansion Capabilities
The LTC 8900 Series can serve as the Master or Slave
Switcher in a SatelliteSwitch® configuration. This
innovative SatelliteSwitch feature enables a single
LTC 8900 system to communicate with remotely
located Satellite systems. Any Allegiant system can
serve as a remote Satellite Switcher. This powerful
feature permits the design of large distributed type
systems. The main control site can view and control
local cameras as well as cameras located at any of the
remotely distributed Satellite sites. The Satellite sites
can view and control only cameras associated with
their local site. When used in this type of
configuration, the main LTC 8900 system can access
up to 256 Satellite sites.
