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.

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.

2
2. Preset, Salvo, System Tour and Event Timer
Preset enables the system to pre-define and save camera
scenes, which can be called up for display either
automatically by the system upon alarms or by operators via
keyboards. Descriptions for the relevant scenes can also be
displayed on monitors at the same time. The Infinova series
receivers and Super Dome cameras are capable of defining
up to 255 such camera scenes.
Salvo permits users to switch a group of cameras to a group
of monitors, hereby providing convenient surveillance over
different scenes simultaneously.
System Tour enables operators to display different camera
scenes, presets and salvos continuously on the same monitor.
One camera scene or one preset can be included in the same
Tour multiple times.
Event Timer permits the system to automatically call up
system tours at a pre-programmed time.
3. Monitor Tour
A monitor Tour is a temporary sequence of cameras for a
called monitor. The sequence can only be displayed on the
called monitor.
4. Control Interface
V2923ACN system provides its controllers and auxiliaries
with following interfaces:
Multiple V2923ACN sites establish inter-communication via
UDP in a network video system;
Controller stations (such as keyboards, PCs) establish
communication with V2923ACN via RS-232 interfaces;
The V2431 Alarm Interface Units communicate with
V2923ACN via RS-232 interfaces to Control alarms;
The Monitor specifically for menu programming (PROG
MON) Communicates with V2923ACN via PROG MON port;
The V2411 Code Generator/Distributors, looping through
DATA LINE with V2923ACN, are used to provide Manchester
Control code for site cameras;
Infinova series Followers (including V2421A, V2422A, and
V2423A) switch external circuits when designated cameras are
called up to designated monitors (V2421A), when designated
monitors are in alarm conditions (V2422A), or when
designated auxiliaries are called up (V2423A). They all
communicate with V2923ACN via high-speed DATA LINE.
5. System Priority

management. A Pseudo Number is the logical number the
system assigns to a specific camera. The camera's Real
Number, the actual physical camera number, can also be used
in the system. Reflection Number indicates camera address in
the system. It is another Real Number which is added behind
the Pseudo Number, so the operations to the current camera
(Real Number) will be mapped to the other camera (Reflection
Number).
9. Network Node
Each V2923ACN in the network is referred to as a node. Each
node in the network maintains all of its full features. To
identify V2923ACNs in a network, each unit is allocated a

V2110 provides the basic operation functions only, with no
programming capability.
3.2 Keyboard Password Entry
V2923ACN user password function serves as a security feature to
allow only authorized users to perform system operation. When a
password for a user is assigned (see Chapter V Menu Programming
– System > Set Priority and User), V2110 operator keyboard cannot
access the system, while V2117/V2116 system keyboards and 2210
GUI software requires a user to enter a user number and a password
for system access.
Note: The password 999999 is defaulted to user number 1.
Therefore, it is recommended to change the default password for
system security. Please refer to Chapter V Menu Programming –
System > Set Priority and User Menu for details on password
programming.
When a password for a user is assigned successfully, the user must
log on to the system before starting operations.
To log on to the system:
1. Enter the user number via keypad.
2. Press the ACK key to confirm. The system will prompt for the
password by displaying the message "PSC" in the keyboard
display.
3. Enter the user's password via keypad. To clear an incorrect entry,
press the CLEAR key, and enter the correct code.
4. Press the ACK key to confirm.
5. If the password verifies, the "PSC" message is cleared, indicating
that the keyboard is ready for system control; if the password
does not verify, the "UC-" message is displayed again (and a
beep is sounded if keyboard sound is enabled), indicating that the
user must re-enter the user number and password.
Note:
1. When the user log on as “Keyboard”, no user name and
password is needed to operate the system;
2. When the user log on as “User”, input any user number except
for 0. User number 1 is defaulted.
To log off from the system:
1. Enter "99" via keypad, and then Press the F1 key
2. Press the USER key.
3.3 Video Selection
Keyboard control of switching system functions is, generally,
"monitor oriented". To achieve video control function via keyboard,
a monitor is first "called" to a keyboard (i.e., placed under the
control of the keyboard), and then, the desired cameras are called to
that monitor.
Selecting a Monitor
To call a monitor via keyboard:
1. Press the CLEAR key to clear earlier keyboard inputs.
2. Enter the number of the desired monitor on the keypad.
3. Press the MON key to call the monitor.
The number of the called monitor (i.e., the monitor under control)
will be displayed on MONITOR LED (or LCD, depending on the
keyboard used).
Selecting a Camera
To call a camera via keyboard:
1. Enter the number of the desired camera on the keypad.
2. Press the CAM key to call the camera.
The number of the called camera (i.e., the camera under control)
will be displayed on CAMERA LED (or LCD, depending on the
keyboard model).

When a camera is called to a monitor, the monitor will display the
live video images captured by the camera, as well as relevant
system information.
3. Press NEXT or LAST key to switch cameras in sequential order.
For example, when the number of the current camera is X, press
NEXT to switch to X+1 camera, and press LAST to switch to X-1
camera.
3.4 Camera Control
If a camera is equipped with motorized lens and pan/tilt, operators
can perform camera site controls (i.e., pan, tilt, focus, zoom, and
iris) after calling the camera to a monitor.
In the case two keyboards with the same priority level control the
same camera, and when the camera is under the control of one
keyboard and the other keyboard tries to control the camera, the
message "IN USE" will be displayed on the monitor. Control will
be denied. The camera can be controlled by the other keyboard only
after the keyboard that controls the camera stop controlling at least
2 seconds.
Pan/Tilt Control
Users can perform pan/tilt control over a desired site camera. The
camera should be called to a monitor before the operation.
To control pan/tilt:
1. Call the desired camera to a monitor.
2. Operate on the site camera with the joystick on the keyboard.
(Holding the joystick in the desired direction will keep the
camera moving until the joystick released or centered.)
3. Release or center the joystick when the camera is at the desired
scene or view, as shown on the monitor.
For control of variable-speed pan/tilts, pan/tilt movement is in
direct proportion to the position of the joystick: the further from the
center the joystick moves, the faster the camera moves.
Camera Control
To control camera lens (Iris, Focus and Zoom):
1. Call the desired camera to a monitor.
2. Press a key in the IRIS (CLOSE/OPEN), FOCUS (NEAR/FAR)
or ZOOM (WIDE/TELE) section for the designated
performance.
3. Release the control button when the camera is at the desired
scene or view, as shown on the monitor.
3.5 Running a Tour
Tour function enables an operator to continuously display a
sequence of different camera views/presets, or to perform salvo
switching. The same camera view or preset can be included in the
same tour multiple times; each dwell time can be defined separately.
V2923ACN supports two tour kinds of tours: System Tour and
Monitor Tour. System Tours are defined by Menu Programming
(see Chapter V). Monitor Tours are defined by System Setup (see
Chapter IV) for a single monitor.
To start a tour:
1. Call the desired monitor to run the tour.
2. Enter the tour number (1-128) on the keypad.
3. Press the RUN key.
4. Press the ACK key.
Note: If the ACK key is not pressed within the 3-second period,
please repeat the procedure from step 2.
Please also note that only one tour can be started on and associated
with a monitor at one time. If a Monitor Tour is programmed to a
monitor and then a System Tour is called to that monitor, the
Monitor Tour is erased.
Press the NEXT or LAST key to change the running direction of the
tour. When a tour is running, the on-screen Status Line shows the
dwell time for each camera in the tour. When running a tour in the
forward direction, an "F" is displayed beside the dwell time; when
running a tour in the reverse direction, an "R" is displayed.
To stop a tour:
Press the HOLD key to stop a tour on the currently displayed
monitor.
When the tour is stopped, the monitor displays the camera that the
tour is stopped on, and the message "HOLD" is displayed in the
on-screen Status Line. While a tour is on HOLD, any camera
control function (e.g., pan, tilt, focus, zoom, iris) can be performed
on that camera.
3.6 Calling a Preset
For cameras equipped with motorized pan/tilt and/or lens with
servo control capability, presets (pre-positioned scenes) may be
defined and stored at the Receiver for automatic call up. Up to 255
presets may be programmed for each camera receiver.
To call a preset:
1. Call the pertinent camera to the monitor.
2. Enter the number of the preset scene (1-255) on the keypad.
3. Press the SHOT key.
Note: Please refer to System Setup - Setting Preset for details on
how to program a preset.
3.7 Calling a System Salvo
The system salvo function permits the simultaneous display of
multiple camera scenes on a group monitors, hereby enabling
operators to survey multiple sites at the same time.
To call a system salvo:
1. Call the first monitor for the desired system salvo.
2. Enter the system salvo number (1-128) on the keypad.
3. Press the SALVO key.
System salvos can also be called automatically from system tours,

4.3 Monitor Tour Programming
A monitor tour is a temporary sequence of cameras programmed
exclusively for the called monitor. A monitor tour may contain up to
64 cameras, and each video input is displayed on the monitor for a
pre-defined period of time (Dwell Time).
Press the HOLD key to hold a currently running monitor tour.
While the monitor tour is in hold status, press the NEXT key to
display the next video input in the pre-programmed sequence, and
press the RUN key to start the monitor tour again. The on-screen
Status Line displays the Dwell Time for each video input.
To program a monitor tour:
1. Call the desired monitor.
2. Place the key switch in PROGRAM position.
3. Enter "62", and then press the PROG key. This puts the system in
Tour Programming mode.
4. Call the camera to be first displayed in the tour.
5. Enter "1" to "60" for the desired dwell time in seconds for the
on-screen camera. To stop and hold the tour on that camera, enter
"61".
6. Press the PROG key to set the dwell time for the on-screen
camera to the value entered. The on-screen display changes to
show the dwell time (or HOLD if "61" was entered in Step 5). If
no more cameras are to be included in the tour, skip to step 9;
otherwise, continue with Step 7.
7. Call the next camera to be included in the sequence. Cameras
need not to be inserted in the tour in numerical order.
Note: Do not enter "62, PROG" during the following steps or
while modifying a monitor tour. It removes all previously
programmed cameras from the tour and necessitates tour
reprogramming.
8. Repeat Step 4, 5, 6 and 7 until all the cameras to be included in
the tour have been programmed.
9. Press the HOLD or RUN key to exit the Monitor Tour
Programming mode. The HOLD key leaves on the monitor the
input from the last camera programmed for the tour. The RUN
key switches the picture to the next camera in the tour and
initiate the tour sequence.
To re-program a single camera in a monitor tour:
1. Press the NEXT key until the desired camera is displayed on the
monitor, and then press the "HOLD" key.

12
2. Enter "0" and press the PROG key,
3. Enter the desired dwell time (1-60).
4. Press the PROG key.
5. Press the HOLD or RUN key to exit the Programming mode.
CAUTION: A system tour has a priority over a monitor
tour. Therefore, calling a system tour to a monitor clears
the current tour programmed for that monitor.
EXAMPLE: Programming a 3-camera monitor tour:
Place the key switch in PROGRAM position, and then proceed the
following steps:
1. Enter "62" and then press the PROG key to clear the previously
programmed monitor tour and access the Monitor Tour
Programming mode.
2. Enter the following key combinations to program the monitor
tour:
"1, CAM" (Includes Camera 1 to be the first camera in the tour.)
"1, PROG" (Sets the Dwell Time for Camera 1 to be 1 second.)
"2, CAM" (Includes Camera 2 to be the second camera in the
tour.)
"2, PROG" (Sets the Dwell Time for Camera 2 to be 2 seconds.)
"3, CAM" (Includes Camera 3 to be the third camera in the tour.)
"3, PROG" (Sets the Dwell Time for Camera 3 to be 3 seconds.)
3. Press the RUN key to exit the Monitor Tour Programming mode
and run the monitor tour.
While a tour is running, press the NEXT or RUN key will change
the running direction of the tour. The on-screen Status Line will
display the dwell time of the current camera. If a tour runs in the
forward direction, an "F" will be displayed beside the dwell time; if
a tour runs in the reverse direction, an "R" will be displayed instead.
Press the HOLD key to stop a running tour when necessary.

4.7.1 Alarm Display Modes
V2923ACN provides five alarm display modes for customizing the
alarm handling options, namely, Single/Sequence, Single/Hold,
Block/Sequence, Block/Hold, and Dual/Hold & Sequence.
1. Single/Sequence
A single alarm monitor can display multiple alarmed videos that are
queued and sequenced to it, each with a programmable Dwell Time
(pre-set to a default of 2 seconds). See the following example of
four alarmed videos received.

2. Hold/Sequence
A single alarm monitor will display multiple alarmed videos. The
first alarmed video in the queued sequence will be displayed and
held on the monitor until cleared. See the following example of four
alarmed videos received.

3. Block/Sequence
Alarmed videos will be displayed across a block of alarm monitors
in a sequential order. Each alarm monitor can display multiple
alarmed videos that are sequenced to it with a Dwell Time of 2
seconds until cleared. See the following example of seven alarmed
videos sequenced to three alarm monitors.

4. Block/Hold
Alarmed videos will be displayed and held on a block of alarm
monitors in a sequential order. When all the monitors are occupied
with alarmed videos, the subsequent alarmed videos will be held in
queue until a displayed video is cleared on a monitor. See the
following example of six alarmed videos queued to three alarm
monitors.

from the 3rd monitor, the 4th
alarm, which is the next alarm
in the que, is then displayed on
the 3rd monitor and the 5th
alarm becomes the next alarm
in the que.

5. Dual/Hold and Sequence
Two alarm monitors are used here: the 1st alarmed video is
displayed on the Hold monitor, and all subsequent alarmed videos
are queued and sequenced to the Cycle monitor with a Dwell Time
of 2 seconds. Once the Hold monitor has been cleared of the
displayed alarm, the next alarmed video in queue will be sequenced
to it, and meanwhile, removed from the Cycle monitor. See the
following example of 4 alarmed videos received.

Dual-Monitor Modes
Three Dual-Monitor modes can be used, these include: DHI, DHA
and DHM. Any of these modes features two monitors operating in
pair: if Monitor 1 is armed, Monitor 2 will be automatically armed
to cooperate with Monitor 1. Please refer to Monitor Arming Types
(Section 4.7.3) for details.
Display Indicator
When the system receives an alarm input, the on-screen Status Line
displays an "ALARM" message until the alarm is removed or the
alarm contact is switched open.
4.7.2 Alarm Clearance Methods
V2923ACN provides three optional Alarm Clearance methods, i.e.,
Instant Clear, Auto Clear and Manual Clear. All the three methods
can remove alarm contacts from the system, and restore the
monitors back to normal operation.
1. Instant Clear (contact-following alarm clearance)
An alarm is cleared when the alarm contact is switched open.
In this method, open the alarm contact first, and then close it to
re-arm the contact.
2. Auto Clear (automatically acknowledged by the system 20
seconds after the contact being switched open)

14
In this method, the system will automatically clear the alarm 20
seconds after the alarm contact is switched open.
3. Manual Clear (manual keyboard acknowledging)
In this method, operator clears an alarm only by manual
keyboard operation.
Note: In Dual/Sequence mode, a monitor must be pre-selected for
alarm clearance.
4.7.3 Monitor Arming Types
Altogether, 18 Monitor Arming Types (detailed in the following
table) are provided for system arming. The last three are auxiliary
arming types.
