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
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.
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:
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:
