Chapter 3 Video Server Setup
There are three kinds of methods to configure the parameters of video server.
1. Through Hyper Terminal (connect DVS with the PC through RE-232 serial ports)
2. Through TELNET (connect DVS with PC through network)
3. Through client-end application software (connect DVS with PC through network)
3.1 Parameter Setup through RS-232 serial port
Mainly set up IP parameters of the video server through serial port. The defaulted IP address
is 192.0.0.62.
Under the case that the IP address is unknown; the Hyper Terminal (need to connect the serial
ports) can only be adopted to configure IP address and other parameters. Under the case that IP
address is known, TELNET can be adopted to configure IP address and other parameters, and can
also modify the IP address by using client-end software.
3.1.1 Hyper Terminal Setup
Please direct connect the RS-232 serial port of PC with the RS-232 serial port of video server
before configuration (there are RJ45 head and DB9 line in the packing carton)
How to establish the connection with the super terminal connection?
Step one: Enter into Hyper Terminal. Click “Start” Æ “Programs” Æ “Accessories” Æ
“Communications” Æ “Hyper Terminal” in Windows system, and the dialogue box below will
appear (Fig. 3.1.1):

3.2 PTZ control
Step1: Connect DVR-471 RS-485 interface with PTZ. Please refer to RS-485 pin definition.
DVS just uses Pin1 (TX+) and Pin2 (TX-) to send PTZ control command.
Step2: You can use remote client software to setup PTZ protocol.
In client software remote setup dialog box, select “Serial Para” tab button. You can select
DVS PTZ parameters in the corresponding dialog box.
Please refer to client software user manual for detail information.

3.3 Configure parameters through client-end software
Before the configuration, please make sure that the PC and the video server has been
established the network connection, you can confirm using PING command. Please refer to the
user manual of DVRDVS client software for detail information.

Chapter 4 Upgrade Firmware
There are two methods to upgrade the DVS firmware. One is using shell commands to ask
DVS to download firmware from FTP server. The other is using PC client software.
4.1 Use Shell Command and FTP Server
1. Using DTE cable to connect the RS232 of DVR to the RS232 of PC.
2. Setup the Hyper Terminal correctly and run it.
3. Make sure the FTP Server (wftpd32.exe) is setup correctly (the corresponding user
manual is in CD) and run it.
4. Make sure the network between DVRDVS and PC is ok.
5. Press "ctrl" and "u" keys of the PC keyboard, do not release them.
6. Switch off and on the power supply of DVRDVS.
7. In the HyperTerminal, the following sentence is appeared:
Please input [u/U] or [ESC] key
8. Release "ctrl" and "u" keys, press "u" key
9. After that, please refer to following pictures.
In the example, I set the DVRDVS as "192.0.0.95" and ftp server as "192.0.0.144". Of course
the ftp server software (wftpd32.exe) is run in the PC whose IP address is "192.0.0.144" and the
network is OK. In this case, DVRDVS (192.0.0.95) will search the PC (192.0.0.144) and
download the firmware from ftp server.

4.2 Use Client Software to upgrade firmware
In the system setup dialog of DVRDVS client software (refer to client software user manual),
there is a button named “Upgrade”:
Select the DVRDVS, Click “Upgrade” button, the following dialo g b ox wi ll be ap p eared :
Fig.4.21 remote upgrading
Click “Browse” button and select the firmware file. Then click “Upgrade” button, to
complete the upgrading process of the video server firmware.

Chapter 5 PPPoE dialup operation
DVR-471 video server supports remote access through network, through browser, through
PPPoE or PPP dialup. Before using this function, please make sure that the software you used in
your device support such functions or not.
5.1 Using PPPoE to establish connection
In the local LAN, use the client software remote setup the DVS parameters. The setup dialog
is looked as following:
In the server parameters sub dialog, enable PPPoE function, input the correct PPPoE user
name and PPPoE password. Click “OK” button and “Save Para.” button. The new server
parameters will be save into video server through network. Reboot the video server, the DVS will
start to dialup the internet.After success, the video server will get a dynamic WAN IP address.
- 21 -
[Explanation] please make sure that ADSL Modem is installed. If it is the first time to set
PPPoE parameters, it needs to reboot video server to establish the connection.
5.2 Client access DVS when using PPPoE
There are two methods:
One is to access using the current WAN IP address of the video server.
When the video server is successful establish the network connection by using PPPoE mode,
it will get the WAN IP address. You can use Hyper Terminal to get the WAN IP address, and
access this IP address through client software.
The other is to access through domain analysis server. By using this mode, you need a PC
with a fixed WAN IP address in the Internet, and there is the domain analysis server software
running in this PC (actually th is PC is the analysis server). We provide such demo DNS software
and SDK.
In the server parameters of video server, there is an item named DNS. Please input the PC
fixed WAN IP address here. When the video server is successfully connection with the internet by
using PPPoE, it will get a dynamic WAN IP address, and send the name and current IP address to
the analysis server. If the client-end software wants to access the video server, it’d first to
connect with the PC used as the analysis server, telling the analysis server which one video server
he wants to access. The analysis server will search all the video servers have been registered, find
- 22 -
out the server with the same name or same serial number, and tell the client-end the WAN IP
address of the video server. After the client-end software get the current IP address, it can establish
the network connection with the video server to get the video images directly.
Here the fixed WAN IP address of PC is 220.184.114.48. We call it as DNS IP. In that the PC,
a demo analysis server software named IPServer is run. It can get the video server information,
including the dynamic WAN IP address of the video server.

Chapter 6 Frequent ask questions
1, Failure to control PTZ
It is possible that the camera and equipment are not connected through RS485
port, or the wrong configuration of the decoder.
2，certain individual channel picture is un-normal
Please check whether the video cable is well connected with the camera and the
Embedded DVS
3，Possible reasons which can cause the failure of upgrading
Failure of the network, IP address error in the FTP host computer, FTP service is
not been booted by PC, the path to upgrade is incorrect, no permission (usually
happened when to upgrade through client-end.)
If the above information cannot meet your demand, please not hesitate to contact
the provider.
