Our company has successfully launched solutions for LED screens spot to spot and one spot to multi-spots based on RF communication technology. At present, RF technology has been widely used in many fields including business, industry, transportation, logistical management, medical insurance, finance and teaching, etc. RF is a kind of wireless telecommunication technology, which is mostly used for standard IEEE802.11B at present. 24GHz made the communication speed between server and terminal reaches to 12Mbps. Based on the wireless channel transmission medium, RF is one of the key technologies that can make moving communication become true, it provides fast, convenient and timely information with characteristics of networking quickly and communicating flexible.

Interface screenshot of LED Editor Software is shown in the image below: Configure RF modules for LED ScreensRF modules connecting with control card (factory default configuration has completed, connecting it with control card directly), as shown in the image below: Factory default, you do not need to configure anymore, if you want to change wireless RF module configuration, please refer to notes: methods of changing wireless RF module configuration. Required conceptions introduction of RFDue to the mutual communication RF modules work in the same frequency point in the way of semi duplex communication, it should ensure to avoid data collision between different RF. Example 1Under stand-alone mode condition, one PC controls one control card connecting with RF, the two RF modules communicate with each other in the way of ask and answer, at this moment, it must be ensure that there isn’t other control cards working with the same RF. Example 2Under multi-mode condition, one PC controls multiple control cards connecting with RF. With configuration ID list, PC software will communicate with one by one through ID list so as to avoid data collision. One PC controls one control card connecting with RF moduleConfiguration steps of Led Editor as follows: click “Options” on menu → Software Setup → Communication parameters then select “stand-alone mode” RF. As shown in the image 21-4 below: After this, users can connect RF with the LED screen just as simple as to connect a local serial port with a LED screen by LAN. As shown in the image below: One PC controls multiple control cards connecting with RF modulesConfiguration steps of Led Editor are as follow: click “Options” on menu → Software Setup → Communication parameters then select “multi-mode”and input password[888]. As shown in the image below: Communication: COM (485/RF) then configures relative values and ID list, as shown in the image below: Configure ID list as shown in the image below: Users can search the LED control card ID by the following steps: Menu → Options → Hardware Setup, as shown in the image below: Screenshot of sending program by RF under multi-mode condition, as shown in the image below: Notes: Configuration introduction of RF modules
