จอแสดงผล LED ไร้สายแบบกึ่งกลางแจ้ง

Semi-outdoor Wireless LED Display (with built-in GSM)
1. Build in GSM Module to realize wireless communication and operation independently.
2. Can store 256 messages, each message can have 256 English characters or ASCII characters.
3. Adjust 16 grade brightness in the daytime and nighttime automatically separating with 4 time segments.
4. High brightness and high contrast, can display clearly in direct sunlight, well suitable for outdoor.
5. Wireless remotely sending information, and also have playing programme as priority
Function. The priority order is: Alarm messages as grade one, real time messages as grade two, advertising messages as grade three and the grade four is default messages, such as advertising telephone and etc.
6. Support on-line software upgrade, easily update the functions of the unit.
7. Remotely control power on / off
8. Information life cycle setup function (can setup playing time of each information)
9. Use super-thin aluminum frame with whole molding, beautiful, firmly, easy to exhaust heating and facilitated to repair.
10. Use moveable fixing bracket, facilitated to install or repair.
11. Use code system, small control data flow
12. Passed Reverse Polarity Performance, Overcurrent Performance, Arc Test, ISO7637 Instant electromagnetism Anti-jamming Performance, Antivibration Performance, Impact Property etc many strict tests of electronic products function targets by China National Computer Products Quality Supervising Test Center and School of Automotive and Transportation Engineering of SHENZHEN Polytechnic.
13. Use big module design, solved the rough screen, inconsistent angle, mosaic and repairing troubles etc problems caused by small module, to ensure the LED display quality and easy to repair.
14. Use multiple safety protection, including over-current protection of power input, auto-protection of inter-circuit, to ensure the safety of the circuit and reliability.
15. Set up play time segments. Timing play messages with 24 time segments. The time segments can be accurated to a second.
16. Can adjust play speed and display dwell time.
17. Power on delay function, Out-of-control protection function and heart-information return function.
