By DE Editors

WIZ-600Wi is a small (3.2-in. x 3.-in.) 2.4GHz IEEE802.11b/g-based wireless module from Saelig (Pittsford, NY) for embedded systems, which supports not only Ethernet but also an RS232C interface, enabling comprehensive Serial-to-Wireless functions.

A Media Independent Interface (MII) for external PHY is also featured, used to connect a 100Mbs Ethernet MAC-block to an off-board PHY IC. A maximum real data streaming rate of 33Mbps to Ethernet is possible, or 115kbaud via RS232. An RSSI signal is available for displaying RF power between the module and its access point. Additionally, the WIZ-600Wi has three general purpose I/O lines.

WIZ-600Wi supports 54Mbps wireless LAN communications and 10/100Mbps Fast Ethernet or RS232 serial connections. Now you can add wireless to your product without a redesign. WIZ600Wi operates as an access connection or a repeater. Ethernet features include dynamic IP configuration by using DHCP server/client; filtering by using MAC address (ACL); multiple SSID & VLAN support; and simple configuration using browser-based AP utility. WiFi features include support for 4/128/152Bit WEP or WPA encryption; EAP certification; and 13 available/selectable channels.

WIZ-600Wi requires 3.3V at >700mA, WIZ-600Wi’s operating range is up to 100m indoors, or up to 400m outdoors. A socket for an external antenna is also provided. An evaluation board with easy-start DB9 (serial) and RJ-45 (Ethernet) sockets is available.

A WIZ-600Wi is $62.50 from Saelig Company. The WIZ-600Wi Evaluation Board is $149.
