　　Points to note

　　The AW-LED flameproof electronic display adopts a hoisting structure.Please pay attention to the display when installing, please avoid direct sunlight, try to avoid rain,So as not to affect the application effect and service life.

　　The AW-LED type explosion-proof electronic display can realize the point-to-point data transmission between the upper computer and the display screen by using the RS232 communication interface.The RS485 communication bus can also be used to realize the data transmission of the host computer, and each display screen connected to the communication bus respectively receives the serial signal corresponding to the device number sent from the upper computer.The received signal is displayed through a dot matrix of ultra-high brightness LED graphic characters. The viewing distance is generally above 15 meters.

　　Technical parameter
