The EZL-80c is a wireless networking module that allows embedded wireless connectivity to be added to products easily and economically. The compact EZL-80c module adds network connectivity to devices with a serial interface on its host microcontroller. It reduces cost and risk and shortens development time for adding networking capability as a standard feature. It adds network connectivity to devices by processing TCP/IP protocol which is required to send and receive data over the Internet. It is possible to extend the distance of serial communications without any change of your legacy systems or replace direct serial connection. Therefore devices can be wirelessly controlled, managed and monitored over the Internet.
