Figure 1-6: LED-328 working mechanism
LED-328 is directly attached to LED display with 08 pin or 12 pin interface.
And it connects eTung's WEBLED server (customer can build its own server
based on requirement) in the internet via GPRS wireless network. In order to
publish information, the user just need to open a web browser and access the
WEBLED server in the Internet and in this way the user can publish and control
the front-end LED information remotely and wirelessly. The information
deployment is done by IE or other web browser, and it is not required to install
typical .exe application, so it is more convenient and the information
deployment can be done anywhere at any time.
