Chapter I General Description
1.1 Description
The software-embedded Central Processing Unit (CPU) Module is
the "heart" of the switching system. It controls the switching bays
of V2040A series matrix switching systems, provides PTZ controls
for site cameras, and offers the programming menu for system
setup.
The V2923ACN External CPU utilizes ARM9 microprocessor
technology, based on LINUX operation system, providing powerful
performance. The ARM9 microprocessor is a 32-bit embedded
system processor, featuring low power consumption and high
performance.
Network Video Capability
Multiple V2923ACNs can be networked to provide both local and
remote control of the site cameras via the UDP protocol. Each
V2923ACN unit in the network is referred to as a node, and each
node in the network maintains all of its full features. To identify
V2923ACN in a network, each unit is allocated a unique site
number, which is assigned through the programming menu.
Easy Operation & Powerful Programming
Utilizing ARM9 microprocessor and LINUX operation system core,
V2923ACN can provide automated electronic surveillance,
allowing even a single user to control an entire CCTV system. A
maximum of 1024 video inputs and 128 video outputs can be
controlled from any one of up to 40 local keyboards and 254
network keyboards, PCs and other devices.
V2923ACN provides powerful menu-driven programming,
featuring 128 user-defined system tours, 128 salvos, 35 event timers,
5 alarm display methods and 3 alarm clearance methods. Optional
character information (e.g., date, time, video input number, video
output title and monitor status) can also be programmed to aid site
surveillance and system operation.
Available Windows-based system setup software greatly simplifies
the initial setup procedure as well as ongoing maintenance of
system parameters. The CPU communicates with controllers or PCs
via either RS-232 data or UDP protocols. Optional GUI software
V2210 further simplifies system operation and programming by
integrating all functions in an easy-to-use Windows application.
Third-party applications written in ASCII codes can also be adopted
for the system.
System Security
System security involves two approaches: System Partitioning and
User Priority. System Partitioning provides keyboard partition and
camera partition to implement detailed control between monitor,
camera and keyboard.
With User Priority, system administrators can define a maximum of
64 system users, and assign each user a password and a priority
level. Each of the 99 priority levels can also be configured as
desired, permitting different access controls for different
users/keyboards.
Network Retransmission
V2923ACN is capable with powerful network retransmission,
which can retransmit various information (such as video lost,
keyboard control, network checking status, the temperature, voltage
and power current information of network checking CPU and
arming/disarming information) to PC directly.
Continuous Performance
V2923ACN is designed for continuous duty operation. Therefore,
there will be no need for any inner maintenance once the
installation is finished. System programming, both via keyboard or
GUI software, is noninvasive and does not require rebooting or
power cycling for storage and/or execution of programmed settings.
All the communication ports adopt standard low-voltage interfaces
such as RS-232, High Speed Data Line and N.C/N.O switching
signal, and all connections/disconnections do not require rebooting
or power cycling. It is also the same with video connections.

network video system.
1.3 Important Terminology
1.
System Keyboard
System Keyboards are the Infinova keyboards for system
control and programming, including V2117, V2116, V2115
full system keyboard, and V2110 operator control keyboard.
V2923ACN can be controlled by up to 40 local keyboards and
254 network keyboards. Different keyboards can be used for
operation simultaneously. Please refer to relevant keyboard
manuals for further instructions.
