Cardinal S2WIFI Serial to Wi-Fi Module


Cardinal Scale’s S2WIFI connects to IEEE 802.11b/g wireless local area networks (wireless LAN) and allows you to wirelessly send data from weight indicators to existing networks, remote displays, printers, laptops, PCs, tablets, and smart phones. The robust S2WIFI allows you to utilize Cardinal’s extensive library of mobile apps for smart phones and tablets. The S2WIFI converts serial to a Wi-Fi signal and supplies wireless Ethernet for any Cardinal Scale indicator. It may be added to an existing network or you can create a stand-alone network. Four communication status LEDs allow you to quickly identify power, link connection, transmit/receive, and reset to the factory default. The S2WIFI features a watertight, weatherproof enclosure in a compact polycarbonate box with clear smoke cover. No external power is needed, since all power is supplied by the indicator.
