Ethernet 10/100 socket
Connect to an Ethernet network with a UTP category 5 cable of length shorter than 100
meters according to the standard. Once the Ethernet cable is connected without error,
Video Server will utilize the Ethernet interface prior to the modem attached to COM2.
COM1 port
This RS232 serial port is dedicated to controlling the PTZ cameras attached to COM1
unless the administrator pre-configures COM1 as an RS485 interface that is accessed
through two pins in the general I/O terminal block.
COM2 port
This RS232 serial port can connect with a modem or the included null modem cable to
utilize dial-up network when Ethernet is not available. If Video Server operates with an
Ethernet interface, the administrator may use this port to control another PTZ cameras
attached to this serial port.

Power source
Pair of pin 11, 12 of AC or DC input is a replacement with the power adapter in case the
range cannot meet the requirement. The voltage of the power source can be AC or DC
and should fall in the range between 12V and 15V. Polarity does not matter. The DC
output through Pin 1, 2 is fed from power adapter of Video Server or pin 11 and pin 12
if an external power source is attached. The current of external devices is limited to less
than 500mA.
The power adapter of Video Server and the external power supply are prohibited to
exist together. Only one source can feed power to Video Server. Improper usage will
result in serious damage.
RS485 interface

How to Install
To easily fit into various environments, 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.
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 inter face
will automatically clear the previous network settings to start new installation.
In the following content, "user" refers to those who can access Video Server and
"administrator" means the supervisor who has the root pass word to configure Video
Server in addition to general access. Administrators should carefully read this manual,
especially during installation.

Shut down all the peripheral devices prior to connection. The video BNC, Ethernet cable
and power adapter are essential for basic viewing function. If the attached cameras
belong to the same motorized model, they can be concatenated to single COM port and
will be differed by camera ID set on the cameras. Refer to the related configuration
section for detailed description.
Power on
Make sure all cables are correctly and firmly connected. Before turning on Video Server,
remember to run Installer program on PC or notebook in the same network first. As long
as the “Reset network at next boot” option in network Web page is enabled, the
Installer program is needed to install Video Server. Turn on cameras, sensors, alarm
devices, and then attach power adaptor of Video Server to the electric power socket.
After the POST (power-on self test) is complete and the result is successful, Video Server
is ready for software configuration as described in this manual. At this stage, network
speed and video modulation type are automatically detected.

Software installation
Easy way with installer program
In order to configure Video Server’s remotely, administrators should keep the MAC
address of the new Video Server’s for identification and initial passwords. After
successfully mounting Video Server’s in the proper position, run the Installer program on
the PC in the same network to locate the newly mounted Video Server’s. Video Server’s
also support manual setup procedures to non-Windows based environments. The
manual procedure is described next.
After the POST is done, Video Server will try to configure itself by detecting the network
environment. If there is DHCP service over the network, the Installer program will catch
the given information, then display the serial number and given IP address for each
Video Server as the figure above. To install the IP address, follow the steps.
○
1
Click on the entry with the serial number you want to install. If the "Assigned" field of
the entry is labeled "Yes", that means the Video Server has already been installed.
○
2
T ype the desired IP address if it is other than the IP address given by the DHCP server.
○
3
Check the box to fix the IP address of the Video Server. Otherwise the Video Server will
lose the network address at next system boot and you have to run this installer again.
○
4
Click to progress the installation.
○
5
After successful notification, administrators may keep the address information and

click directly on to access the Video Server in the default browser.
If the IP address is taken by another network device in the network, the Installer
program will pop out another message window to warn that the assigned IP conflicts. In
this case, administrators should ask the network supervisor for a vacant IP address.
While “Use this IP whenever system
boots", is checked, a dialog window may
pop out to ask for “Server FTP Port” and
“Root Password” because they are
already changed by administrators to
other than default settings. If the original
settings are lost, restore default settings
and run software installation again.
Once the installation is complete, administrators should follow the First access to
Video Server section for necessary checks and configurations.
Building Networks for People
DVS-104 User Manual v1.00
- 17 -
Manual way with existing programs
For those environments such as MAC, Linux, Unix or other operating systems, whose
installer is not yet available, some common network tools including ARP and PING can be
used to install Video Server. Before proceeding further, make sure ARP and PING
programs exist.
First, type arp –s “assigned IP address” “Ethernet address” to add an entity in the
system’s name table. The Ethernet address is identical to the serial number of Video
Server and should be typed in the appropriate format like “uu-vv-ww-xx-yy-zz” or
“uu:vv:ww:xx:yy:zz”, which depends on the operating system.
Once the name entity is added, type ping "assigned IP address” to invite the new Video
Server. If it replies, that means Video Server has accepted the assigned IP address and
is ready for access. The first several ping requests may fail during the self-configuration
period of Video Server. Sin ce the accurate grammar of ARP and PING depends on the
operating system, refer to its related help manual.

First access to Video Server
Change initial password of administrator
Starting the Web browser to connect to the assigned IP address of Video Server, users
will be asked for user name and password by an authentication message window. A root
password, identical to the Video Server's MAC address, 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.
Manage user privilege
For complete protection from illegal usage, Video Server provides three privileges and
always needs user name and password before access. The lowest level is DEMO mode
whose services are subject to administrator's permission. The standard level is the USER
mode that consists of twenty user profiles. Each user is able to access Video Server
under the given privilege, except for system configuration. The twenty user profiles are
also maintained by the administrator. The highest level is ROOT mode that only opens to
administrators for initial setup, system configuration, user administration and software
upgrade. The user name of the administrator is internally assigned to “root”.
Complete the network settings
Although Video Server already can be accessed after software installation in local area
network, administrators should complete the network settings in the configuration page.
The complete network configurations including subnet mask as well as the IP address of
default gateway and DNS are provided by your network administrator or Internet service
provider. Once the wrong network settings make Video Server fail to work, refer to
Appendix A to restore factory default settings.
By default Video Server will need administrator's installation every time it reboots. If the
network settings are sure to work all the time, disable the install option in network
configuration W e b page or Installer program.
Details about configurations are described in the relative category of the Chapter
Definitions of Configuration

Modem Environment
Hardware installation
Though Video Server is designed to serve real-time images in Ethernet, it also supports
the dial-up network. 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, Video Server will detect if any external modem is connected to COM2. As
soon as a modem is detected, the heartbeat LED will flash periodically. If no modem
responds, Video Server will assume the included null modem cable is connected to
perform system configuration. Then both LED’s under the power LED will turn on until
the dial-up connection over null modem is established.
Installations of both null modem and modem are introduced as follows. The null modem
mode can be used for point-to-point connection in local environment; the modem mode
also applies to TA in ISDN network. Though the baud rate can be setup to 115200 bit per
second, the actual data rate depends on the network connection.
In the following content, dial-in connection denotes a passive Video Server waiting for a
phone call to establish a point-to-point connection. Dial-out connection denotes an
active 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.

Shut down the peripheral devices prior to connection and keep the power adaptor
unplugged until other cables are firmly connected. In the environment without Ethernet,
administrators can use the included null modem cable to connect to Video Server directly
and access point-to-point. After necessary information is entered and saved, turn off
Video Server and remove the null modem cable. Follow the installation of modem mode
in next paragraph to connect to Internet. Note Video Server will not really reset system
where it is used to in null modem mode.

connect to “http://200.1.1.1” in
the web browser. “200.1.1.1”
will be the default IP address of
Video Server in dial-in connection;
“200.1.1.100” will be the given
IP address for the user's PC by
Video Server. The use r name an d
password are the same as what
was entered during software
installation.
After successful authentication, administrators should see the motion pictures in the
main page. When using Microsoft Internet Explorer, administrators must allow installing
a plug-in provided by Video Server additionally prior to viewing motion pictures.
Change initial password of administrator
For best security, administrators must change the password on the security page of
configuration immediately. After changing the password, the browser will display the
authentication window again to confirm the new password.
Manage user privilege
Administrators can add up to twenty user profiles in the Security option. While Video
Server accepts dial-in connection and acts as a server , the user name and password used
in dialing are the same as what is stored in the user database managed for web access.
Any managed user can be authorized during PPP negotiation and access web pages.
However, only administrators can access the configuration page.
Complete network settings
Basically the null modem is used to setup the later attached m odem where Eth ernet i s
not available. Refer to the modem setting in the COM2
section for details about ISP
information. After everything is set and saved, turn off Video Server and replace the null
modem cable with modem for dial-up network. Since the null modem connection is used
to configure Video Server in advance for modem connection, administrators cannot
connect again without restarting the system.

First access to Video Server in modem mode
If the dial-out is not prohibited and the attached modem is recognized, Video Server will
send out the system startup log and connection log by email or FTP according to user’s
settings as soon as the system is ready. That can be used to verify if the settings work.
Then Video Server will always wait for someone to dial in. To dial in Video Server, setup
a connection in dialup network on PC where the phone number is the phone line of Video
Server. After connecting successfully, start the Web browser and connect to
“http://200.1.1.1” . In this case, Video Server runs as a dial-up server and assigns the IP
address of “200.1.1.100” to the PC at the other en d. While seeing the authenticatio n
message window, type “root” as user name and the MAC address of Video Server as the
initial password. The point-to-point connection allows users connecting Video Server for
surveillance at any time.
If the administrator has setup some conditions in the application Web page or the script
file, Video Server will automatically dial out based on the administrator's configuration.
Refer to the Application
section in the Chapter Definitions of Configuration for special
security applications.
