Wireless 3G Solution for LED Display Screens

For LED screens, 3G systems will provide access, by means of one or more radio links, to a wide range of telecommunication services supported by the fixed telecommunication networks and to other services that are specific to mobile users. A range of mobile terminal types will be encompassed, linking to terrestrial and/or satellite-based networks, and the terminals may be designed for mobile LED screens or fixed LED screens.

Wireless 3G Traits for LED Display Screens

1. Using 3G router Modem
2. Cheaper (users can choose Unicom WCDMS or Telecom EVDO)
3. The third-party platform unnecessary
4. Easy and reliable

The wireless 3G system structure as shown in the image below:

Communication theory introduction: LED control card will auto connect to the Led Editor service center running in remote PC-console through domain name parameter so as to building up a communication link.

PC in place A controls the LED screen in place B through Wireless Solution 3G

Preparations: apply for a domain name (such as: alahover.gicp.net) from http://www.oray.com or other dynamic DSN websites.

1. Place A: LED screen; ④ a Xixun Company’s M-series control card; ③ 3G router, a 3G network card of Unicom WCDMS or Telecom EVDO. Note: connecting 3G router with LED intelligent control card directly by cables, the two must be in same segment.
2. Place B: ① one PC; ② the 3G router connecting with internet.

Steps of building up a communication link with the LED screen and Control PC through 3G

Five steps are needed to build up a communication link between the LED screen and control PC through wireless 3G, which are:

Step 1: Configure relative hardware parameters of ④ LED control card in one PC installing Led Editor Software in Place A.

Configuring PC server’s IP address for the control card then running Led Editor Software, click “Options” on menu → Hardware Setup → input password 888, as shown in the image below:

Please take note of the following points that are very important when configuring the hardware for building up the 3G communication link between the LED screen and the controlling PC:

1. Users can apply for two domain names, a main one (such as alahover.gicp.net) and a spare one (such as alahover.dyndns.org). It is recommended that these two names belong to different domain name suppliers.
2. Screen mnemonic name helps users to remember and distinguish the screen which is controlled by the control card.
3. If the PC gets static IP then please select “Server IP” option and input the IP address directly. After finishing the above steps, please confirm that control card has connected with the router by cables.

Step 2: Set up forwarding rule in Router configuration in place B②.

Enter the router’s LAN IP (such as 192.168.8.1) in ①PC Explorer then login. Sending data of port 31297 to ①PC IP(such as 192.168.8.225), as shown in the image 24-3 in below:

Note: This server port is 31297, which is a fixed value.

Step 3: Login the DN in place A (two methods, users can choose any one).

Method 1: download Client Software in the ①PC then login the domain names (including main and spare DN), as shown in the image below:

Method 2: Users can set up DN login in the ②router with DSN function. As shown in the image below:

Step 4: Communication Parameters in Multi-mode

Click “Options” on menu → Software Setup → Communication parameters → select “multi-mode” and input password 888, then tick box in the front of “Internet Single-Console”, as shown in the image below:

Step 5: Configuration work completed.

Led Editor Software for the control PC can search the control card on the client-side automatically and run the instructions, such as sending a program to the LED screen and turn on/off the LED screen, adjust time and brightness for the LED screen, etc, as shown in the image below:

One PC controls multiple LED screens through wireless 3G

Under this condition, the setup steps of each control card are the same with those of one PC that controls one LED screen. Below you can find the LED screen connection diagram through wireless 3G:
