Status LED’s
Each time Video Server starts up, it will perform power-on-self-test, abbreviated as POST,
to examine every hardware module. As soon as the administrator plugs in the power
connector both LED’s under the power LED will flash one by one until the diagnosis is
done. If the result is good, both status LED’s will turn off for a while and then follows the
pattern below. If any module fails, refer to the Appendix A for the error pattern and
follow the trouble-shooting procedures. If the system still cannot operate normally,
please contact your reseller for technical service.

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.

-9-
COM port
This RS232 serial port can connect with a modem or included null modem cable to utilize
dial-up network when Ethernet is not available. If Video Server operates with Ethernet
interface, administrators may use this port to control PTZ camera attached to VIDEO.
General I/O terminal block
1 ÅDI+ INPUT (Max. 50mA,12VDC)
2 ÅDI- INPUT
3 ÅSW_COMMON OUTPUT (short with NC at initial state)
4 ÅSW_NOPEN OUTPUT (Max. 1A, 24VDC or 0.5A, 125VAC)
5 ÅRS485 B (inverting)
6 ÅRS485 A (non-inverting)
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.
Video Server provides one digital input and one relay switch. Pin 1 and pin 2 can be
connected to 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
external devices.

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.
Power adapter
Connect the power jack of the included power adapter. Connecting the power adapter
should be the last operation while physically installing Video Server.
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.

-11-
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.

-12-
Ethernet Environment
Hardware installation
Before installing multiple Video Server’s 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. 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.
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.

-13-
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.

-14-
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 the modem
port . 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.
Cable connection
Null modem mode

-15-
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.
Modem mode
If users have setup a remote dialup server or subscribed to an ISP service, Video Server
can be configured to dial to the server upon user-defined events. Otherwise it will wait
permanently for the user’s call to establish a network connection to provide services.
Before installation, make sure the necessary dialing information is correctly setup via
Ethernet or null modem connection.
Power on
Make sure all cables are correctly and firmly connected. Turn on cameras, sensors, alarm
devices, and then finally attach the power adaptor of Video Server to the electric power
outlet. Since most automatic detections of hardware perform when the system starts,
Video Server should be turned on after all peripherals are turned on and ready.
