GPRS Modem Specification

Outdoor LED display is widely used as new media for information deployment.  Currently, the LED display is either directly attached to a PC or remotely  controlled by SMS through the GSM mobile communication network. For the first solution, it requires cable planning & installation, which is inconvenient costly. For the second solution, the information is not guaranteed to be real time due to the delay of GSM mobile network and functionality of the system is very limited.

Now, there is another solution, GPRS Modem. GPRS Modem allows the user to build  a wireless, real time and inexpensive remote LED display information deployment system.

Function of the wireless LED system· Connect to the server automatically, and keep online all the time · Create new program, edit program, delete program · Set display parameters of every program (color, speed, stay time, display mode, and etc.) · Set display screen parameter (horizontal pixels, vertical pixels, and etc.) · Publish program point to point, point to multipoint, multipoint to multipoint · Look over the historical program and send them to LED screen · Support many scan mode, such as 1/16, 1/8, 1/4, 1/2 and 1/1

APPLICATIONSGPRS Modem - Webled is used for LED remote publishing. In Webled users can create new program and send them to LED dispaly screen.
