The usage of LED display screens is getting wider, such as advertising LED screens, traffic LED screens, etc. However, users have to do a lot of work to update the LED displays contents due to numerous numbers and widely distribution. In order to solve this problem, our company has successfully researched and developed LED display screens control systems based on GPRS. As long as users can access the internet and find the control card which connects with GPRS, they can control display contents and achieve off-site control. In this way, users can solve problems by transmitting over a long distance and with one PC it controls multiple LED display screens. GPRS Traits for LED Display Screens

Interface screenshot of M-GPRS wireless Software as shown in the image below: Configure M-GPRS for LED ScreensThe factory default configuration has completed, connecting the M-GPRS with the control card directly as shown below. Factory default, do not need configure anymore, if you want to change M-GPRS configuration, please refer to notes: methods of changing M-GPRS DTU configuration. Operating steps of PC-ConsoleThere are three steps to configure the PC console: Step 1: Run M_GPRS.exe software then input following parameters, as shown in image below: Step 2: Select GPRS DTU of on-line screen which needs to be operatedmap out port. As shown in the image below: After confirming, users can see mapping port, as shown in the image below: Step 3: Run Led Editor softwareselected serial port in step 2, as shown in the image below: Note: this is virtual serial port so its baud rate may be any values in down-drop box. Configuring LED Editor for LED Screens with One Control CardOne PC only controls one control card connecting with M-GPRS DTU. Configuration steps of Led Editor as follows: Click “Options” on menu → Software Setup → select “Communication parameters”: tick the box in the front of “stand-alone mode”, GPRS. As shown in the image below: After this, users can connect GPRS with screen just as simple as connect local serial port with screen by LAN. Configuring LED Editor for LED Screens with Multiple Control CardsOne PC can simultaneously control multiple control cards connecting with M-GPRS DTU. Configuration steps of Led Editor as follows: Click on “Options” in menu → Software Setup → select “Communication parameters”: tick the box in the front of “Multi-mode”, input password, (default password is 888). As shown in the image below: Communication type is GPRS and there is VSP port table, as shown in the image below: Screenshot of sending program by GPRS under multi-mode condition, as shown in image below: Methods of changing M-GPRS DTU configurationConfiguration preparation and connection. You can insert web-enabled GPRS data card into SIM connector then connect M-GPRS configuration serial port with PC port by serial port line, at last, connect M-GPRS antenna. Login configuration interface, three steps are needed: Step 1: running M-GPRS-DTU-CF.exe software, click on “options” button then select the serial port that PC can connect with M-GPRS in the box of “COM”, click OK. Click on “start configuration”. As shown in image 20-13 in below: Step 2: turn on M-GPRS power (power port is inner positive and exterior negative). Step 3: when version information appears in configuration box, please press “enter” into configuration interface. Note: turn on M-GPRS power within 15 seconds after clicking on “start configuration”. Configure M-GPRS parametersStep 1: configure “date center domain name/IP”, input IP address then press “enter” into the next step. Step 2: configure “DSC port”input DSC monitoring port then press “enter” into the next step. Step 3: configure baud rate which consistent with control card, have eight numbers and end number is 1. Step 4: other parameters can be omitted, press “enter” until “storage configuration” and “restart” appear then input “YES” to complete configuration. At last, turn off power and restart. Note: please inquiry suppliers about DSC domain name/IP and port. Methods of configuring serial port baud rate of the control cardSerial port or internet connects with control card under stand-alone moderunning Led Editor → Menu → Options → Hardware Setup Baud rates of COM-R232 and M-GPRS must keep consistent with each other.
