1.1 System Introduction
The hardware system use the control processor ARM7, Sumsang main stream, 32 bit. Embedded the real time multitask operating system, that is researched and development by self, and it have high stability, high processing speed, quality reliability, high hardware scanning speed. Those are the features of the system. The control system have both synchronous advantage and asynchronous advantage. It could achieved not only the powerful function. It can play multiplex special effects, that is the advantage of the synchronism, but also able to work in line-off, and unnecessary to maintain, Which is the advantage of the synchronism. It’s a technological revolution of the LED screen control sphere, that used in single or double color, indoor or outdoor.
1、 Supporting the animated format of GIF.
2、 High speed of scanning, the scanning frequency could achieved more than 120 Hz, The picture that display in it is steadiness and non-swinkle. 3、 It Could control 2048x1024 point in single color, or 1024x512 point in double color when used single card. It could link more than two card and display synchronism.
4、Supporting RS485 and TCP/IP, strongly processing capability of date. Could display on the frontstage and communicate on the backstage.
5、16M flash inbuilt in the board, and 16/24 dot character inbuilt in it. It could save date when power-off. And it could add the CF card.
6、Supporting play the picture format of BMP, JPG JPEG ect. Text format of TXT, RTF,DOC ect, and the Excel.
7、Supporting the display of multiple windows and multiple task, could set more than 64 logical area, and display independently.
8、Supporting digital clock count time and countdown, safe day, the Chinese calendar, universal time ect. Have the special function of simulate clock. 9、Have much special effect, more than 30 kinds of display format, and could made special effect alone. It have a great variety of patterns. 10、Supporting 10 level of brightness adjust, it could be set by software or by adding the brightness sensor.
11、Supporting temperature, humidity, remote-control and many industry sensors interface. It have rich outside extending function.
12、Supporting RS232/RS485, TCP/IP. It could added optical fiber transceiver, wireless GPRS transmission mold ect.
13、Supporting more than 100 kinds of hardware scanning interface, Nearly compatible all of the screen scanning interface, which is domestic. 14、Have secondary development feature. It could provide solve program according to user’s requirements, and provide the free interface provisions.
15、Setting software and display software could be used alone, Interface
friendly. The system software could update through long-distant.

2.2 Hardware connection explanation
1、TCP/IP ethernet connection: The standard 10M ethernet connection, 8needles RJ45, uses the GB code mesh wire with the HUB association, uses the cross-wire with the computer net cardassociation; 2、RS232/485 connection: Compatible RS232 and the RS485 connection 3、DC 5V connection: Direct current 5V entrance, standard direct-current powersupply plug, inside positive outside negative;
4、A/D transformation entrance: 8 pin A/D transformation entrance, the pin definition for details sees the wiring method;
5、Driving plates switches: 8 driving plates switches, mainly uses when the RS485 network communication screen number address establishment; 6、50 pin demonstrations output port: Demonstrated the data 50 needles output port, used to connect the display monitor HUB board;
7、Time set port: Uses to output the successor time cut-out signal 2 needles outlet,controls the display monitor power on or off;
8、Temperature control port: Uses to gather the temperature the signal input connection;
9、Remote control port: The input connection that Uses to connect the infrared remote control singnal;
System test button: The button that Uses to test red, green and yellow full 10、
