LED displays are widely seen on the streets , bus stations, communities, etc. People use them to display advertising, information publishing including texts, images, and videos. In the short distance LED display control system, FourFaith F8914 ZigBee terminal is the part of data transmission.
F8914 ZigBee terminal is connected to the LED board via RS232/RS485. It supports three node types, coordinator, routing and end device. There s one coordinator in the ZigBee network. The central node is installed to the PC via RS232 at the control center. Information is sent from the central node to the general node via ZigBee network, and then output from the RS232/RS485 port and display on the board.
F8914 ZigBee terminal is used for small data and short distance transmission. It supports joining the network automatically. The routing type unit in the network acts as the repeater. Sleep mode in end device decreases the power consumption.
Model : Fourfaith F8914
Quantity : 7 units for testing
All LED boards are with RS485 port, and the distance between two LED boards is about 100meters. All LED boards are connect to F8914 terminals (general node) via RS485. Then another F8914 should work as central node connected to the PC. The general nodes send data to the center node, then the center forwards the information data to the server directly. The software analyzes the data in the server and sends the control data to the terminal , in this way the server can control the LED display.
