Asynchronous control technology for LED display
Asynchronous control technology for LED display
1:Adapter PC by serial port RS232 protocol through RS232 and RS485 adapter.
Adapter is light type.
2:Control panel to receive PC through serial communication transmission shows
the information needed
a. Longitudinal points within 128 dots, Lateral points up to 2000 points. If the longitudinal is
16 dots, Lateral of up to 4000 points.
b. Large capacity storage support secondary character, Chinese characters and a large number
of proprietary type, storage capacity for 16dots.
c. It can be controlled by computer, also can be displayed offline.
d. Information can be saved when the power outage 1 year.
e. With functions of real-time clock calendar.
3:Single cable core (four-core) using the four wire system,A pair of difference received twisted-pair cable,
another pair difference twisted-pair cable are responsible for sending. Communication distance of 1200 meters.
Adopt total linear network structure. the maximum load is 32 bit machine.
4:LED graphic display control protocol:This agreement support matrix monochrome, double colors
by networking LED display. Connection form is main line, PC is Upper machine. Under machine for
LED display is the single chip microcomputer. Using four-wire carrier system. Online agreement
is RS485. PC with a serial port RS232 and Support TCP/IP protocol transmission.
