Product Description

This miniature 'Wifi' Wireless LAN to RS232 module provides a cost effective, high performance Radio data link, between devices over a WLAN network. The S103 is compliant with the WLAN 802.11b protocol standard and can operate in Ad-Hoc or infrastructure mode, supporting 64/128-bits WEP security.

The wifi modules are very simple to operate and offer low current consumption, allowing for extended battery life when used in mobile applications. Serial Data can be supplied directly to or from a microcontroller, thus keeping the component count down and ensuring a low hardware cost.

The modules can be easily set up via console or web configuration. The software includes a Virtual Com driver and device-search utility, this software is available from the support section of the Tellus website. To assist in setup two status-pins are also provided to indicate connection status (connecting, connected, disconnected, command).
