1996R CPU DESCRIPTION
The 1996R CPU is the Central Processing Unit for the 2050
MegaPower II Matrix Switching and Control System. The
2050 MegaPower II is a CCTV surveillance system having
multiple video inputs, multiple video outputs, and multiple
control stations. The 1996R CPU is capable of controlling a
maximum of 1024 video input sources such as cameras and
video multiplexers and a maximum of 128 video outputs such
as monitors and video tape recorders.
The 1996R Central Processing Unit controls all video
switching and alarm response in the 2050 MegaPower II
System and provides programming menus for 2050 system
setup. This manual describes the installation, setup
programming, and operating procedures of the 1996R CPU.
SYSTEM FEATURES
Video Switching Control: The 1996R CPU controls video
switching of all cameras to all monitors in the 2050 system.
Switching is performed in response to operator keyboard
request or by automatic action via Tours, System Salvos,
Alarm Response, or Timed Events.
Tours: A Tour is an automatic sequence of camera inputs
displayed on one monitor. Each camera is displayed for a set
period of time (the “Dwell Time”). A Tour can include the
same camera multiple times, and is reversible. Tours are
identified in the 1996R as Monitor or System Tours.
Monitor Tours (“Scratch Pad Tour”): A Monitor Tour is
a temporary sequence of cameras which is programmed for
an individual monitor via keyboard only. A Monitor tour
may contain 64 cameras, with a dwell time for each camera.
System Tours: A System Tour is a pre-programmed tour
that is defined via 1996R setup menus. Sixty-four separate
System Tours can be programmed for callup, by operator or
automatic timed Event, to any monitor at any time. Each
tour may contain 64 cameras, with a dwell time, preset
camera scene, and auxiliary action for each camera.
System Salvos: A System Salvo is a group of cameras that
can be switched simultaneously to a contiguous group of
monitors. Sixty-four System Salvos can be programmed for
operator or automatic callup to any set of monitors. A
maximum of sixteen cameras may be included in each System
Salvo, with an optional preset scene and auxiliary action for
each camera.
Alarm Response: Cameras can be automatically switched to
specified monitors based on external alarm signals called
Alarm Contacts. A maximum of 1024 alarm contacts can be
programmed for automatic response. Camera inputs and
monitor outputs are individually armed for alarm response.
Camera Alarm Programming: Individual alarm contacts
can be programmed for callup of a specific camera or
camera salvo on receipt of alarm, including a dwell time,
preset camera scene, and auxiliary action for each camera.
Monitor Alarm Programming: Individual alarm contacts
can be armed for display (of the associated cameras) on
specified monitors on receipt of alarm. Different alarm
display and clearance modes may be programmed for each
monitor. Alarm contact association can be changed
dynamically by programmable timed Events.
(Refer to the Appendix, pages A-3 to A-7, for an overview of
Alarm Programming and the various menus and functions
provided in the 1996R CPU for setting alarm response.)
Timed Events: A maximum of 35 user-programmable time
slots, called Events, can be programmed. Each Event can be
programmed for automatic callup of System Tours and Alarm
Contact Tables on different days of the week, week after week.
System Tour callup: Each Event provides automatic
callup of any System Tour to any monitor at a specific time
of day and day of the week.
Alarm Contact Table callup: Each Event can call any of
five Alarm Contact Tables at a specified time of day, to
define a different association of alarm contacts to monitors.
