（3） Put a WCDMA SIM card into the MR-900W wireless router, and turn on the power. MR-900W will dial

up for online automatically, then we can browse website and send/receive email. We can also check the

device’s working status through the following interface. We Key in “http://192.168.1.1” on the address

bar, and then type in the user name as “root” and password as “1234” for login. After login the working

interface for MR-900W，we can check the device’s online speed as well as data traffic.

MR-900W wireless router has “Port Forwarding”,“DMZ Host”, and“DHCP Server”functions，so that customers

can use it as a normal router for data transfer as well.

Application case B: Configure MR-900W for web video device

MR-900W 3G WCDMA device can be used for long distance wireless video monitoring. It’s easy for use and

provides high quality image. We illustrate the procedure for connecting web video through MR-900W by DMZ

12

host method as following.

Setup Steps：

1. Reading IP address from web video camera

Each web video camera has its own IP address, and we can set the IP address. You may set the IP address as:

192.168.1.20。

2. Configuring MR-900W

a) Log into the configuring interface for MR-900W. The default gateway IP address for MR-900W is

“192.168.1.1”，Please key in “http://192.168.1.1” on the IE browser，and then put user name as “root”

and password as “1234”. You will be able to see the configuring interface for MR-900W. (As show in

the following figure:

13

b) Configuring DDNS。

i. Why should we use DDNS？

The IP address we get from WCDMA is the dynamic IP (IP address changes for each dialing

online). If we configure the DDNS for MR-900W, then we can access the device, no matter what IP

address we get from each dialing.

ii. Is it necessary that we use DDNS？

It is not necessary that we use DDNS. The reason for choosing DDNS is because the IP address we

get from each WCDMA dialing is different and that will affect device accessing. However if the

WCDMA card provides the fixed IP address, then we do not need DDNS in that situation.

iii. How to configure DDNS？

Log-into MR-900W configuration interface, and click on left side “DDNS” button, then click on

DDNS service and configure domain name and password, then click on “save”.

14

c) Configuring DMZ Host: Log-into MR-900W configuration interface, and configure the IP address of

web camera as the IP address of DMZ host from MR-900W. After all these steps, click on “restart”, and

restart the device.

3. Video Access

First, set up the MR-900W and then connect the MR-900W to webcam network port with a crossover cable,

and then turn on the power for both devices. You may open an IE browser on a computer connecting to the

internet, and enter the domain name to get video access. (Such as http://etungtest. gnway.net)

15

4. Notes：

1. Must use crossover cable for connecting MR-900W to computer and webcam;

2. MR-900W and the network camera must be in the same network segment. The factory default gateway IP for

MR-900W is: 192.168.1.1, therefore you should set up the webcam’s IP between 192.168.1.2 and

192.168.1.254. Of cause, you may change the gateway IP for MR-900W to other network segment, as long as

you keep MR-900W and webcam in the same network segment. MR-900W is required after each change the

settings to take effect after restart.

Application case C: Configuring MR-900W for serial port DTU function

MR-900W not only has the function for wireless router, but also has the function for DTU. Here’s how

MR-900W can be featured as DTU.

1、Set up mServer

See “mServer installation manual”

2、Configuring MR-900W

You may go to the configuring interface and setup the following parameter (As show in the following figure):

1. IP address (or domain name) for primary data center

2. primary data center port

3. user serial port configuration

16

After finishing the configuration, click on “save” and restart the device.

3、Get MR-900W online

After MR-900W is configured correctly, and the antenna and power supply connected correctly, you should

make sure to put a WCDMA card into MR-900W to access the internet. MR-900W will dial-up to connect to

mServer automatically. When the MR-900W connected to the mServer, it will appear online on the mServer.

At this point, the MR-900W can be mapped to a virtual serial port or a TCP port over mServer. It can also

remotely send and receive data through DCC interface and PC software.

Application case D: Configuring MR-900 for using Ethernet port and serial port simultaneously

MR-900W has both Ethernet port and serial port, and these ports can be used simultaneously. Let’s assume that

we would like to connect a PLC to report the collecting data (such as concentration, and pressure etc.), and at the

same time we need to connect a webcam for real time video surveillance. In this case we use point to center mode

for serial port transmission and DMZ host mode for Ethernet port transmission simultaneously.

1、Setup mServer

See “mServer installation manual”

17

2、 Configuring MR-900W

You may go to the configuring interface and setup the following parameter (As show in the following figure):

a) IP address (or domain name) for primary data center

b) primary data center port

c) user serial port configuration (match to PLC serial port parameter)

Then, configure the parameter for network camera (configuring DMZ host and DDNS). See the steps in

application case B

18

3、Get MR-900W online

After MR-900W is configured correctly, and the antenna and power supply connected correctly, you

should make sure to put a WCDMA card into MR-900W to access the internet. MR-900W will dial-up to

connect to mServer automatically. When the MR-900W connected to the mServer, it will appear online

on the mServer. At this point, the MR-900W can be mapped to a virtual serial port or a TCP port over

mServer. It can also remotely send and receive data through DCC interface and PC software. At the same

time, you may type in configured domain name into the IE browser, and visit the device that connecting

to MR-900W.

Application case E: MR-900W used for remote connecting to LAN by VPN

MR-900W can be used for expanding corporate virtual network and remote accessing virtual network through

VPN function. For example, users can access corporate LAN through MR-900W dialing up. However this

approach requires the local area network router support VPN function, and PPTP tunnel access, since the current

MR-900W only support PPTP network protocol. Here are some ways to implement this VPN connection.

1. System Structure

19

MR-900W Remote Access LAN by using VPN Mode

2. Hardware and network preparation

a) One network router supporting VPN function (Supporting PPTP connecting mode as well),

b) This router connects to a LAN and is able to access internet,

c) One set MR-900W（Include accessory）,

d) One WCDMA card

e) One computer

3. Setup Steps

a) Configuring router for PPTP login

We use RV042 router (from Linksys) as example to explain the steps for configuring PPTP login. First of

all, this router has VPN function and supports PPTP accessing. Second, we login to the router and click

on “VPN” “PPTP” for enable the PPTP server, and then, set up an IP segment for VPN connection.

After then we may set up a user name and the password for VPN accessing (As show in the following

figure).

20

Of cause, the configuration interface and the selection items could be different for various routers.

b) Configuring MR-900W

Login the configuration interface for MR-900W, and click on “VPN function” for the following

configuration:

Type ——PPTP

IP or domain name for VPN server —— The corporate LAN side IP (If the corporate LAN side IP is not

fix, then you may acquire a domain name and type in the domain name here)

User name —— The user name that we setup on the router (RV042)

Password —— The password that we setup on the router (RV042)

VPN function ——ON，(open VPN connection)

Click on “save”, and then “restart” to restart the device and finish the configuration. (As show in the

following figure)

21

c) Check for dialing up status

After login MR-900W, we may check the dialing up status as show in the following figure:

22

At this time, MR-900W get connection to the user’s local area network, if you visit “http://192.168.0.207”

within the corporate LAN, you may access to the login interface for MR-900 and, other data information

within the LAN as well. As this point, if the MR-900W was connected to a video server, and made a port

mapping or DMZ host, you may access to video surveillance by visiting “http://192.168.0.207” within the

corporate LAN.

4. Notes：

1. The IP address of the computer or video server connecting to MR-900W with the network should

not be in the same network segment with corporate LAN side IP address. For example, if the

corporate LAN side IP is “192.168.0.*” network segment, then the MR-900W need to be in other

network segments, such as “192.168.1.*” network segment.

2. MR-900W and all the device connecting to the MR-900W need to be in the same network

segment. Since the default gateway IP for MR-900W is “192.168.1.1”, if you would like to set

the IP address for the device connecting to MR-900W in “192.168.0.*” network segment, you

should change the gateway IP for MR-900W in this segment as well, such as “192.168.0.1”. 23

Example 1 Configuring MR-900W to be connected with AIXS 205 (webcam) for wireless video surveillance

1. System structure

2. Hardware preparation

1、 One set MR-900W (include accessory)

2、 One WCDMA card

3、 One AXIS 205 network camera

4、 One computer with internet connection

3. Setup steps

a) Reading IP address from web video camera (AXIS205)

Each web video camera has its own IP address, and we can set the IP address. The IP address for AXIS205 is:

192.168.1.20。

b) Configuring MR-900W

i. Log into the configuring interface for MR-900W. The default gateway IP address for MR-900W

is “192.168.1.1”，Please key in “http://192.168.1.1” on the IE browser，and then put user name

as “root” and password as “1234”. You will be able to see the configuring interface for

MR-900W.

24

ii. Configuring DDNS。

♦ Why should we use DDNS？

The IP address we get from WCDMA is the dynamic IP (IP address changes for each dialing

online). If we configure the DDNS for MR-900W, then we can access the device, no matter what IP

address we get from each dialing.

♦ Is it necessary that we use DDNS？

It is not necessary that we use DDNS. The reason for choosing DDNS is because the IP address we

get from each WCDMA dialing is different and that will affect device accessing. However if the

WCDMA card provides the fixed IP address, then we do not need DDNS in that situation.

♦ How to configure DDNS？

Log-into MR-900W configuration interface, and click on left side “DDNS” button, then click on

“DDNS service” and configure domain name and password, then click on “save”.

25

iii. Configuring DMZ Host:

internet, and enter the domain name to get video access. (Such as http://etungtest. gnway.net)

26

5. Notes:

a) Must use crossover cable for connecting MR-900W to computer and webcam;

b) MR-900W and the network camera must be in the same network segment. The factory default gateway

IP for MR-900W is: 192.168.1.1, therefore you should set up the webcam’s IP between 192.168.1.2 and

192.168.1.254. Of cause, you may change the gateway IP for MR-900W to other network segment, as

long as you keep MR-900W and webcam in the same network segment.

c) MR-900W is required after each change the settings to take effect after restart.

Example case 2 Configuring MR-900W for remotely controlling color LED screen

With the popularity of 3G communications, wireless transmission speed is greatly improved, and makes it

possible to remotely control LED color screen. As following, we illustrate how to connect MR-900W with

C-power5000 (DS06T) LED control card to achieve remote control

1. Preparation for Configuration

♦ On set MR-900W (include antenna)

♦ One piece C-Power5000(DS06T) LED control card

♦ One cross cable

♦ One serial cable to connect C-Power5000(DS06T) to a computer

♦ 5V DC power supply

27

♦ Install mServer(download from this website: http://www.etungtech.com.cn/xzzx/index.asp)

♦ Install LED control card software LedCenterM, (software can be downloaded from this website:

http://www.2008led.com/zh-CN/newproducts.html?fileTypeID=705)

♦ One computer with internet connection

2. System Setup

2.1 Setup mServer on your server

See mServer setup manual, or call us at +86-10-64880675. First-time customer can also use Etung’s testing

server, and the IP address for mServer is 123.196.114.95, port 7000.

2.2 Read-Back control card information

You may connect the C-Power5000(DS06T) control card to the computer through the serial port, run

LedCenterM (3.51version) software, and define a LED screen corresponding to a C-Power5000(DS06T)

control card (default password is 16888).

28

After defining the serial communication with the LED screen, you may read-back the current control card

information. (As show in the figure)

29

After finishing read-back control card information, you may need to note down the IP, port, and gateway. Here

you may use the default setup for C-Power5000 (DS06T) control card, which is “192.168.1.222” for control card

IP, 5200 for port, and “192.168.1.1” for gateway.

2.3 Configuring MR-900W

1） Turn on the power for MR-900W, and connect to the computer with a crossover cable (note: set the computer

as obtain IP address automatically). You may type in http://192.168.1.1 to log into web configuring interface

for MR-900W. After enter the user name as “root” and the Password as “1234”, click on “login”.

30

2） Setup the IP and port for mServer

3） Set up User Agent Client

The IP and port for this User Agent Client is the IP and port that just read-back from the LED control card.

After setup click on “restart”, at this point, the MR-900W is connecting with LED control card with the crossover

serial cable.

31

2.4 Configuring LED control card to connecting with MR-900W

1） When the MR-900W is connected to the mServer, you may find it appear as on line on mServe. At this time,

you may map the MR-900W to TCP port 5200 by selecting the MR-900W and then click “Mapping

Management” over the mServer.

2） After mapping is completed, you may do the following setup for LED control card once more; open“Setup”

“Advanced” “Define Screen”, and do the following configuration：

32

As show in the figure, you may change the communication mode as networking communication mode. If you

would like to use Etung’s server, the IP address would be showing in the figure. If you install mServer and

LedCenterM3.51 on the same computer then the IP address could be 127.0.0.1. If you install mServer and

LedCenterM3.51 on different computers but in the same LAN, then you may set the IP as a LAN IP such as

192.168.1.20.

After finishing this setup, you build a good wireless communication system between MR-900W and C-Power5000

(DS06T) for remotely controlling information display.

3. Setup connection for multiple color LED control systems

Above, we illustrate how to build one set color LED screen remote control system. If we would like to build

multiple sets of color LED remote control system, please pay attention for the following settings.

33

As show in the above figure, suppose ① color LED control card is connecting to ① MR-900W, and ②

color LED card is connecting to ② MR-900W. In this case, the TCP port for ① color LED control card is

5200, then you need to set the ① MR-900W’s port for User Agent Client as 5200 as well. At this time the

① MR-900 connects to mServer and displayed as online, and maps to TCP port 5200 over mServer. For the

① color LED control card, you also set the communication port as 5200. At the same time ② MR-900W

displayed as online over mServer as well. Since the TCP port 5200 has been occupied by ① MR-900W, you

need to map the ② MR-900W to a port other than TCP 5200 port over the mServer, such as TCP 5300 port.

Therefore, you should set the ② color LED control card’s communication port as 5300, which means ②

LED control card will update data through port 5300. In short, you need to set the communication port for

LED control card as same as the User Agent Client port for MR-900. Meanwhile, the mapping TCP port over

the mServer needs to match the communication port that is defined in the LED control card software.

However it is not necessary that both end of the ports are the same.
