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, 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 time-out 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.
