General I/O terminal block
1 Å DI+ INPUT (Max. 50mA, 12VDC)
2 Å DI- INPUT
3 Å SW_COMMON OUTPUT (short with NC at initial state)
4 Å SW_NOPEN OUTPUT (Max. 1A, 24VDC or 0.5A, 125VAC)
5 Å RS485 B (inverting)
6 Å RS485 A (non-inverting)
The Video Server provides a very flexible general I/O interface to combine with the user’s security
devices such as sensors, alarms, lighting or door locks. The general I/O terminal block has six pins for
device control. These pins can be divided into two categories based on their functions, including RS485
and digital inputs and outputs.
If the device connected to COM has an RS485 interface, wire two control lines to pin 5 and pin 6. After
switching to RS485 on the configuration page, the PTZ control commands will be directed through pin 5
and pin 6. If the distance from the controlled device is too far to allow accurate function, an external
power source may be used to pull high the RS485 signal.
The Video Server provides one digital input and one relay switch for device control. Pin 1 and pin 2 can
be connected to an external sensor and the state of voltage will be monitored according to the
programmed scripts in configuration. The relay switch can be used to turn on or off the external device.

Each time Video Server starts; it will perform a Power-On Self Test, abbreviated as POST hereafter, to
examine every hardware module. As soon as the administrator plugs in the power adapter, both LEDs
under the network LED will flash one by one until the POST is done. If any module fails, both LEDs will
indicate to the users the error according to the pattern listed in Appendix A. If the result is good, both
LEDs will turn off for a while and then follows the pattern below. Network interface depends on the
peripherals including Ethernet UTP cable, modem or null modem cable. If the Ethernet cable between the
Video Server and Ethernet hub is good, Video Server will choose the Ethernet network. If Ethernet is
unavailable but a operational modem is connected, the network interface will be PPP with modem. If
either of the above is not the case, The Video Server will try the interface of PPP with null modem.

Restore button
There is a button hidden in the box for restoring the system factory default settings. When the system fails
to install or operates abnormally, use the included assistant stick in the package and follow the following
procedures to reset the system back to its original status.
Poke the assistant stick into the hole to press down on the restore button. Restart the system by
unplugging and re-plugging the power jack. While keeping the button pressed, the system will perform
POST twice rather than the usual once, which can be observed from the flashing LEDs. After the system
flashes the LEDs for the second time, withdraw the stick to release the button. The system will have
restored factory default settings at that moment.

Installation
To easily fit into various environments, the Video Server automatically detects the attached interfaces and
configures itself to the best condition. Therefore users need not care whether the connected cameras are
either NTSC or PAL, how to select the network between Ethernet and modem, and whether the Ethernet
speed is 10Mbps or 100 Mbps. If the connected motorized camera is on the support list, users only need
to plug and play without complicated configurations.
The Video Server supports Ethernet and modem interfaces according to the user's existing network.
Ethernet can provide higher bandwidth to achieve the best performance while dial-up network with
modem is more common in current Internet applications. Refer to the related installation section for your
network environment. If both interfaces are available, Ethernet is recommended and will be chosen as the
first priority if Ethernet cable and modem are concurrently attached. Managing to install in the other
interface will automatically clear the previous network settings to start new installation.
In the following content, "user" refers to those who can access the Video Server and "Administrator"
refers to the supervisor who has the root password to configure the Video Server in addition to general
access. Administrator should carefully read this manual, especially during installation.

Ethernet Environment
Hardware installation
Before installing multiple the Video Servers at the well-chosen locations, the Administrator should
memorize the serial numbers on the packages respectively for future use.
Cable connection
Shut down all the peripheral devices prior to connection. Connect the supplied cables from the Video
Server to related devices according to the following steps.
Note: The power adaptor must be kept unplugged until other cables are firmly connected.

Power on
Make sure all cables are correctly and firmly connected before turning on the Video Server. Turn on
cameras, sensors, alarm devices, and then attach the power adaptor of the Video Server to the electric
power socket*. After the POST (power-on self test) is complete and the result is successful. At this stage,
network speed and video modulation type are automatically detected. After addressing procedure is
completed, the Video Server is ready. If the detection of video modulation fails, Administrator may
change the setting on the configuration page. Refer to the configuration section for further information.
.
Connect the jack of the power adapter to Video Server prior to plugging the utility end into the
utility power socket. It will reduce accidental electric surge shock.

Initial Access to the Video Server
The Video Server can be connected either before or immediately after software installation onto the Local
Area Network. The Administrator should complete the network settings on the configuration page. For
complete protection from illegal usage, the Video Server provides two privileges and always needs user
name and password before access. The standard level is the USER mode that consists of twenty user
profiles. Each user is able to access the Video Server except for system configuration. Twenty users’
profiles are also maintained by the administrator. The highest level is ROOT mode that only opens to
Administrator for initial setup, system configuration, user administration and software upgrade. The user
name of the Administrator is internally assigned to “root”.
When connecting to the Video Server, users will be requested for user name and password by an
authentication message window. A root password, identical to the Video Server's serial number, is needed
for the initial access to a newly installed Video Server. The administrator must change the root password
immediately after the initial installation to ensure security. The new root password should be well
memorized since there is no way to retrieve or recover it. After changing the password, the browser will
display an authentication window again to ask for the new password.
The other important part is network settings. The software configuration above makes the Video Server
easily accessed through local networks. However Administrator should review the network settings on the
configuration page according to the existing service. The safe and easy way is to compare the network
settings with another PC or workstation in the same network.
By default the Video Server will acquiring IP address automatically every time it reboots. If the network
settings are sure to work all the time, disable the “Reset network at next boot” option if this IP address is
already reserved for this the Video Server. Clearing this option will fix IP address of the video server
every time it boots up. If the option stays checked, the Video Server will pick up any available IP address
automatically every time the system boots up.

Modem Environment
Hardware Installation
Before installing the Video Server, the administrator should memorize the serial numbers on the packages
respectively for the initial passwords.
To use a dial-up network, the Ethernet socket should be left disconnected since Ethernet is the first
priority among available interfaces. After powering up, the Video Server will detect if any external
modem is connected to the modem port. Once a modem is detected, the heartbeat LED will flash
periodically. If no modem responds, the Video Server will assume the included null modem cable is
connected to perform system configuration. Then both lower LEDs will turn on until null modem
connection is established.
If users have setup a remote dialup server or subscribed to an ISP service, the Video Server can be
configured to dial to the server upon special events. Otherwise it will wait permanently for the user’s call
to establish a network connection to provide services.
In the following content, dial-in connection denotes a passive the Video Server waiting for a phone call to
establish a point-to-point connection. Dial-out connection denotes an active the Video Server to dial out to
the other end of a dial-up server or any Internet service provider, abbreviated as ISP, to request a
point-to-point connection.

Cable Connection
Shut down the peripheral devices prior to connection. Connect the supplied cables from the Video Server
to the related devices according to following steps. Note that power adaptor must be kept unplugged until
other cables are firmly connected. For the first access to the Video Server without Ethernet, Administrator
may use the included null modem cable to connect to COM for direct connection. It is also convenient for
administrators to access the Video Server through the null modem cable directly without modem or
Ethernet card. After necessary information is entered, a modem can be used to dial into the Internet.
Power On
Make sure all cables are correctly and firmly connected. Turn on cameras, sensors, alarm devices, and
then finally attach power adaptor of the Video Server to the electric power outlet*. Since most automatic
detections of hardware perform when the system starts, the Video Server should be turned on after all
peripherals are turned on and ready.
Connect the power jack of the power adapter to the Video Server prior to plugging the utility en
d
into a utility power outlet. It will reduce accidental electric surge shock.

Initial Access to the Video Server
Through direct connection by null modem cable the Administrator can open the default web browser and
type in 200.1.1.1 as the address and press enter. Note that 200.1.1.1 will be the default IP address in a
dial-in connection and 200.1.1.100 will be the given IP address for the user's PC by the Video Server. The
user name and password are the same as what was entered during installation.
After successful authentication, Administrator should see the motion pictures in the main page. When
using Microsoft Internet Explorer, Administrator should allow a plug-in provided by the Video Server to
install additionally. For best security, Administrator must change the password on the system page of
configuration immediately. After changing the password, the browser will display the authentication
window again to ask for new password. Note that the new password will also be used in the next dialup.
To make the Video Server successfully work in dial-in and dial-out modes, follow the procedures below
for basic configurations. If people other than the Administrator will be granted to use the Video Server,
the Administrator should add these user profiles in the Security option. When the Video Server accepts
dial-in connection and acts as a server, the user name and password used in dialing are the same as what
was stored in the user database managed for web access. Any managed user can be authorized during PPP

negotiation and access web pages. However, only Administrator can access the configuration page.
There is more information needed for correct modem operation. Refer to the modem setting section in
configuration for further settings. The Video Server will wait for someone to dial in. If the Administrator
has setup some conditions in the application, the Video Server will automatically dial out based on the
Administrator's configuration. Refer to the application section in configuration for special security
applications. After everything is set and saved, turn off the Video Server and replace the null modem
cable with modem for dial-up network. Since the null modem connection is used to configure the Video
Server in advance for modem connection, Administrator cannot connect again without restarting the
system.
If dial-out configuration is activated, the Video Server will dial out to send a system startup log to test and
drop the call after the pre-configured period.

How to Use
The Video Server is a well-designed stand-alone video server. With the built-in web server, authorized
users may use web browser Internet Explorer to watch the video and hear the audio streamed from the
Video Server. The powerful video compression processes up to 30 frames per second and makes the scene
in your browser as real-time display. The powerful audio compression processes the real-time audio and
makes the synchronization of video and audio correctly. Also benefit from web interface, each function
and each configuration has its specific URL that allows advanced users easily integrate them into existing
software program.
The preparation of the primary users to utilize the Video Server is quite simple since Administrator has
done the majority of the installation. Most Administrators find the installation is easy in general
environments because most settings are automatically configured. Open your web browser and connect to
the Video Server just like a general web site and the audio and video will present on demand. Make sure
the web address of the target the Video Server is accurate.

Authentication
After opening the Web browser and typing in the URL of the Video Server, a dialogue window pops up to
request a username and password. For Administrator’s initial usage of the Video Server, enter the
username as “root” and the password as the serial number in capital letters. The serial number can be
found on the labels under the body of the Video Server and the top side of the carton. The primary users
will be allowed to enter as soon as the Administrator finishes adding user profiles. Upon successful
authentication, the following figure is displayed.
The foreground is the login window and the background shows the message if authentication fails. The
user may check the option box to save the password for future convenience.

Client Setting
There are two settings for the client side. One is “Media Option” for users to determine if audio should
be muted. The other is “Protocol Option” which allows choices on connection protocol between client
and server. There are three protocols choices to optimize your usage - UDP, TCP and HTTP.
The UDP protocol allows for more real-time audio and video streams. However, some packets may be
lost due to network burst traffic and images may be obscured.
The TCP protocol allows for less packet loss and produces a more accurate video display. The downside
with this protocol is that the real-time effect is worse than that with the UDP protocol.
The HTTP protocol must be selected if the network is protected by a firewall and it only allows HTTP
Port (80) to be opened. In this mode, audio will not be sent and only video is operational. If no special
need is required, UDP protocol is recommended. Generally speaking, the client’s choice will be in the
order of UDP → TCP → HTTP. After the Video Server is connected successfully, “Protocol Option”
will indicate the selected protocol. The selected protocol will be recorded in the user's PC and will be
used for the next connection. If the network environment is changed, or the user wants to let the web
browser to detect again, manually select the UDP protocol, save, and return HOME to re-connect.

There are three ways to adjust system date and time. The easiest is to make the Video Server "sync with
computer time". The second is to set the date and time manually. Notice the format in the related field
while typing. The third “Automatic” is to make the Video Server periodically synchronize with
timeservers over the Internet. It may fail if the assigned NTP server cannot be reached or it is within a
local network. Leaving the NTP server blank will let the Video Server connect to default timeservers. If
some specific timeserver is assigned, type it in the text box. Domain name or IP address format is
acceptable as long as DNS server is available. Do not forget to set the "Time Zone" offset for local
settings. It only affects the hour in NTP method. Once the check box of “Automatic “is checked, video
server will synch with NTP server periodically. Update interval can be set as hourly, daily, weekly or
monthly in the “Update Interval” item

This can be tedious having to perform software installation whenever the Video Server starts. Therefore,
once the network settings, especially the IP address, have been entered correctly, uncheck this option. If
this option is disabled, the Video Server will boot up by the current IP address. The Video Server can
automatically restart and operate normally after a power outage. Users can run IP installer to check the
IP address assigned to the Video Server if the IP address is forgotten or using the UPnP function provided
by the Video Server (MS Windows XP provides UPnP function in the “my network place”)

In both methods, a "2nd" server can be provided for backup connection for “1st”. However the primary
server information should be entered first. If the primary server is not set, the related FTP or email will be
deactivated. Note that it may take time to connect to the secondary server after the first one fails and it
may affect some applications when conditions happen too often. For SMTP, video server will
automatically try to connect to 2nd SMTP server while failing to send out to 1st SMTP caused by any
wrong SMTP information.
For security or network integration, Administrator also can hide the server from the general HTTP port by
changing "HTTP port" to other than default 80. “Local FTP server port” can also be changed to other
than default 21. These ports of “Control Channel Port”, “Audio Channel Port” and “Video Channel
Port” which are used in media transmission can also be changed. Administrator should have enough
acknowledge before changing the default port.
NOTICE: if video server is behind NAT, port mapping is necessary for connection outside NAT.
HTTP port, control channel port, video channel and audio channel port totally 4 ports mapping
needs to set in the NAT router to enable fully video and audio streaming by video server.
If the Video Server works in variation or low bandwidth (comparing with video bandwidth) environment,
the client side will receive the poor quality of media. For improving this situation, you can check the
“Improve audio quality in low bandwidth environment” item. It can make the audio quality better, but
the media delay is longer and real-time issue is bad. If the network performance is worst, please select
the”UDP protocol“as the communication protocol in “client setting”
The Video server can disable audio streaming by check “Mute” check box. Any client connect to the
Video Server will receive video only. Once “Mute” is checked, the LED2 for heart beating status will
blink about every 2 seconds. It would be obviously slower than the normal condition with both video and
audio streaming. This way user can tell video server’s streaming behavior just from LED2
After everything is set, click on . A warning message will pop up. Click on to confirm. The
Video Server will automatically restart. If "Reset network at next boot" is kept checked, run the installer
procedure again. Otherwise the Video Server will restart automatically.

UPnP and DDNS Settings
“Enable DDNS” This option turns on the DDNS function.
“Provider” The provider list contains four hosts that provide DDNS services. Please connect to the
service provider’s website to make sure the service charges.
“Host name” If users wants to use DDNS service, this field must be filled. Please input the hostname that
is registered in the DDNS server.
“Username/E-mail” The Username or E-mail field is necessary for logging in the DDNS server or notify
users of the new IP address. Note: when this field is input as “Username” the following field must be
input as “Password”.
“Password/Key” Please input the password or key to get the DDNS service.
“Enable UPnP” This turns on or off the UPnP function. When UPnP is turned off, the camera cannot be
found through “my network place” in MS Windows XP. If the UPnP network component is installed in
Windows XP, the hostname of the Video Server will be shown with bracketed IP address in “my network
place”. Ex: the Video Server (at 192.168.0.96). That is: The hostname of the Video Server is “Video

Video codec parameters
Options on this page will affect the image on the main page seen by users.
"Text on Video" The text will be displayed in the black bar above the video window with a timestamp.
The timestamp is captured from the date and time of the Video Server that is maintained by a built-in
real-time clock.
"Color" Setting is independent of the connected camera and B/W option might speed up the encoder a
little.
"Size" Option allows users to adjust the image size taking into consideration bandwidth and visual effect.
Five options are available including half, half×2, normal, normalx2 and double. Half×2 consumes the
same bandwidth as half but is the same size as normal. Of course the image is not as good as normal.
Half×2 is especially suited to low bandwidth environments like a dial-up network. Normalx2 consumes
the same bandwidth as normal but the same size as double.

The image quality of double is better than normalx2 but double will consume the most bandwidth. Once
double is chosen for video size, the “Maximum frame rate” will be limited up to 10 only.
"Modulation" The type is auto-detected during initialization, but the Administrator can still set it
manually.
VS3102 uses MPEG4 codec compression for best streaming solution. The compressed video data is far
less than JPEG in normal cases but it still depends on the level of difference between every two sequential
images. There are three dependent parameters provided for adjustment.
"Maximum Frame Rate" This limits the maximal refresh frame rate, which can be combined with the
"Video Quality Control" to optimize bandwidth utilization and video quality. If the user wants to fix the
bandwidth utilization regardless of the video quality, choose "Fix Bit Rate" and select the desired
bandwidth. The video quality may be poor due to the sending of maximal frame rate within the limited
bandwidth when images are moving rapidly. Consequently, to ensure detailed video quantization rate
regardless of the network, it will utilize more bandwidth to send the maximal frames when images change
drastically.
The option "Enable Motion Detection" will control the event of motion detection on the application page.
If this option is enabled, the preset windows framed by red lines will appear in the video window even if
no option is checked on the application page. If this option is disabled, then any settings related to motion
detection will have no effect. Motion detection will increase system load. Enter the motion detection
option page for advanced configuration.
To adjust video from external cameras, use "Flip" to map the video vertically and "Mirror" to map the
video horizontally.

PTZ camera configuration
Since the Video Server can be used in either Ethernet network or PPP network, the single serial port can
be used to control either external COM port devices like a PTZ camera or modem. While in PPP interface,
go to Modem page for modem configuration. Options on this page will be ignored.
The Video Server supports RS232 and RS485 interfaces to control external serial port devices. Refer to
the hardware description to connect an RS485 device. The included camera control cable can be used for
Sony or Canon cameras.
Administrator can pull down the list to select UART "Interface Mode" according to the connected device
and select the camera model directly to save time in detection.
The "Baud Rate (bps)" of the serial port is up to 115200 bps.
The Video Server can support any other custom camera by selecting "Custom Camera" type. If the
attached device is not a PTZ camera, a specific URL can be utilized as an alternative method. See the
advanced section for details.

If the attached motorized camera is not on the support driver list, choose the proper UART interface and
pull down the driver list to select Custom Camera type and click on for further
configuration.
Setup the serial "Port Settings" according to the instruction manual of the custom camera. Then enter the
specific command related to PTZ in the respective field. The custom command for "Control Setting"
should be edited in ASCII format. The Video Server will interpret the ASCII format command to binary
string. For instance, “012000ABCD” will be sent out of the COM port as five hexadecimal bytes of 01,
20, 00, AB and CD. If the command string is composed of two or more commands, a comma ‘,’ should be
inserted to separate each command. Each comma represents 200 milliseconds. For instance, a command
to pan left may be “01000305” and a command to stop panning may be “01000300”. The user may edit
the applicable command as “01000305, 01000300” in the Move Left field. This means the camera will
pan left for 200 milliseconds. When everything is set, click on to save the commands and click on
to close the command setting window.

Modem and dialup settings
In PPP interface, a modem option will work instead of camera control. Configurations include modem
initialization and outside dial-up server. If the users will setup with external sensors and alarms for
property security, dial-out is needed to send some snapshot-attached e-mails when the preset conditions
are triggered. In such applications, also remember to choose Network option to enter mail server address
and recipient's e-mail address. If "Dial out allowed" is not checked, Video Server will not send out any
snapshots when events occur and the settings except for "Initial modem command" in this page will
have no effect. The system will preset the attached modem to eliminate echo and mute line sound. The
modem commands further initially, type into the box. Edit The prefix "AT" should be included.
Administrator should choose an appropriate "Dial Method" according to the local POTS environment. An
incorrect dialing prefix may cause the Video Server to fail when dialing out. "Redial attempts" means
how many times the Video Server should try to connect to each ISP. Setting the value in "Disconnect
after minutes" will force the Video Server to drop the connection when there is no activity on the

connection for the specific period. The range of this period is from 1 to 240 minutes, with 0 indicating a
continuous connection. Administrator may let the Video Server keep the connection for a while to allow
connections from outside. The IP address given by the ISP can be taken from the connection log that is
mailed or uploaded when dial-up connection is successful. Setting the value to zero will make the Video
Server always keep the connection.
Based on the settings of DI/DO in the application, the system will send mail or upload via FTP with
image attachment upon the event occurring. In that case the Video Server will need a network connection
and automatically dial out to the pre-configured server outside. When a connection is successfully
established, the Video Server will send out a connection log to notify given network settings. For those
installations that may switch the network interface between Ethernet and PPP, Administrator should
notice that the settings of FTP or SMTP servers might be different from what is in an Ethernet
environment. If the network interface is changed, Administrator may need to configure them in advance.
The Video Server will try the second ISP as a backup when the first ISP fails and exceeds the redial
attempts. "ISP phone number" should be the complete phone number including country code and area
code if necessary. "Login username" and "Login password" are used to pass the PPP negotiation
requested by the ISP server. Note that the pair of login name and password is dependent on the ISP and is
different from what is used in the authentication process in web access.
When using modem as the network connection, the Video Server will mute the audio
automatically, and send video only because the low bandwidth environment doesn’t meet the
requirement for both. In the Client setting page, protocol option will be set as Http protocol.

continuously over a configured period. This mode can be used to integrate with another web server to
serve overloaded requests. If the date and time suffix option is disabled, the Video Server can use FTP to
upload and overwrite snapshot files periodically. The remote folder of snapshot files for FTP can be
configured on the network page. The snapshot period is between "Snapshot begin" and "Snapshot end"
and it will repeat everyday. The snapshot interval is set in "Snapshot every second".
"Event operation" can be used to combine motion detection with devices attached to digital input, to
drive devices attached to digital output, or send out snapshots for evidence. It helps users establish an
easy security system. Administrator may choose any combination of conditions to form special
applications according to their personal needs. The Video Server will continuously monitor the channel
and digital input every half second. Once the user-defined conditions are matched, the Video Servers will
capture three stages of events and react based on the "Trigger action" settings. The post-event snapshot
can be configured to be delayed after events happen according to the setting in "Take snapshot at
seconds after event". The three stages of snapshots will be VPRE.JPG, VTRG.JPG and VPOS.JPG. Since
the same event may exist for a while, Administrator can set delay time in "Delay seconds before
detecting next event" to reduce multiple triggers by the same event.
There are two kinds of "Trigger condition". For digital input there are four options provided to combine
with the user's device. Rising and falling will make events happen once. For motion detection, there are
window names shown below as choices. Refer to the previous section for configuring motion detection.
Note that larger object size and lower sensitivity will make it more difficult for the Video Server to detect
varied images. Once the "Trigger condition" is matched, the Video Server will drive the digital output
device and/or upload snapshots based on the "Trigger action" settings. The application settings should be
carefully examined to operate accurately. If Administrator are not sure of the digital output status before
configuring applications, "Reset output" can be used to return the digital output to the default “Normal
Close” state.

can be changed by the Administrator, or any image on the Internet that can be located via URL.
"Background graph", the background image from system memory are quick to get but limited by
memory size. Images from external resources can be larger and more beautiful but will need more time to
load. If the background is skipped, the background color will fill the browser window. Administrators also
can give the system logo a "logo link" to refer to another web site. The "font color" and "background
color" can be chosen from sixteen colors to achieve the best visual effect.

FTP
The Video Server not only has web service for easy access but also has a built-in FTP service to make
system integrators easy to use. According to settings on the application page, the Video Server can
sequentially send updated snapshots over a specific period to an external server with choices of
overwriting and time suffix. For security staff, the Video Server can directly send snapshots to an external
server as evidence according to event settings. Through the Video Server’s FTP daemon, Administrator
can quickly update configurations and maintenance.
Those files with GIF extensions which are used for a homepage layout and can be read and overwritten.
They also can be downloaded by managed users. Other files will be explained below.
Uploading snapshots periodically to an external FTP server
In sequential mode, the Video Server will send out snapshots according to interval and period settings. If
snapshot files are intended for quick updates, it is better to skip date and time suffix. The file name will
then be video. jpg. If the snapshots are used to suffix occasional monitoring, with date and time that can
help Administrator classify easily them.
Customizing homepage images
There is a small icon before each link that can be changed by Administrator. Administrator may change
the look of the logo, background and image buttons by him or her self. There are three types of logos and
backgrounds, blank, default and other URL. The default method will use the image stored in the Flash
memory. Administrator may change the default logo, background image and button images by uploading
customized ones. The followings are the referenced file names and size limitations.

Viewing system log
Download SYSTEM.LOG and open it with any text viewer. The content of the file reveals useful
information about configuration and connections after the system boots up. It helps Administrator to
easily find out whom and how the Video Server was accessed since all network access to the Video Server
is recorded with timestamp. The system log will scroll to keep the newest messages as eliminate old ones.
Uploading the configuration file
To update each the Video Server’s configuration at once, upload the accurately formatted batch file to
CONFIG.INI. It is recommended to keep the original format, but changing values. Refer to the section in
configuration for details and optional values as well. After successfully receiving and verifying the file,
the Video Server will self-update the configuration and restart automatically. Refer to the previous section
for further information.
Software revision upgrade
Customers can frequently check the appropriate product folder on our web site to download the latest
firmware. Only Administrator can upgrade the system firmware of the Video Server.
Easy way via Upgrade Wizard
Run the Upgrade Wizard included in the product CDROM and proceeds by the prompts. Refer to the
user's guide of Upgrade Wizard for details.
Alternative via FTP
1. Decompress the compressed file in a local folder. A file named FLASH.BIN should appear.
2. Use the FTP program and change the working directory to the local folder where FLASH.BIN exists.
3. Connect to the Video Server with user name as “root” and password.
4. Use the PUT command to upload FLASH.BIN to the Video Server. The file size is near 1.5 mega bytes.
It will take approximately 2 seconds in a local network, 2 minutes by null modem connection or 6
minutes by modem, but still subject to user's network.
5. After upload is complete, close the connection.
6. If the received FLASH.BIN is checked without error, the Video Server will update the software in
Flash memory and restart automatically. When the Video Server starts writing firmware, both status LED
indicators will stay on until system restarts. It takes about 30 to 40 seconds. User must keep the power
stable during the update process. After the system restarts, the Video Server may need installation
depending on whether the “Reset network at next boot” option is enabled or not. After the Video Server
