Application case A: Configure MR-900W for high-speed internet connection

MR-900W may be directly connected to one computer Ethernet port to achieve wireless online, and also it

may be connected to a switcher or a HUB to make a few computers sharing the internet. We will illustrate these 2

types of connection as following.

1 Direct connecting a computer to the internet through MR-900W

Set up procedure

1 Connecting the computers Ethernet port with MR-900W through a cross cable.

2 Choose computers IP as automatically obtain IP address

Click on control panel network connecting local connecting right click onlocal

connecting, and then click on property, and then choose automatically obtain IP address

8

If you would like to set a IP address for MR-900W, then you should set the IP address for MR-900W as

192.168.1.1and IP address as 192.168.1.20(as show in the following figure)

3 Put an 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

devices 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-900Wwe can check the devices online speed as well as data traffic.

2 Connecting multiple computers with internet through MR-900W

Set up procedure

1 Connecting MR-900W to the upstream port of a switcher or a HUB through a cross cableand connecting

all the computers which are in the network to the downstream port of the switcher or the HUB.

2 Choose computers IP as automatically obtain IP address

Click on control panel network connecting local connecting right click onlocal

connecting, and then click on property, and then choose automatically obtain IP address.

If you would like to set a IP address for MR-900W, then you should set the IP address for MR-900W as

192.168.1.1and IP address as 192.168.1.20(as explained above )

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

devices 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-900Wwe can check the devices online speed as well as data traffic.

MR-900W wireless router has Port Forwarding,DMZ Host, andDHCP Serverfunctionsso 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. Its easy for use and

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

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

192.168.1.1Please key in http://192.168.1.1 on the IE browserand 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:

http://192.168.1.1/

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 v
