The WI232+ is a single-port WiFi to serial device server that lets you connect serial devices to 802.11b/g/n wireless networks quickly and easily. The WI232+ simplifies connectivity to devices where cabling is prohibited or mobility is required. This next generation of the legacy WI232 adapter provides enhanced software features, a factory reset button, new status LED and a smaller form factor.

Based on the Lantronix xPico™ WiFi® module, advanced security, robust data handling capabilities and high serial speeds are all built in. Using a method called serial tunneling, the WI232+ encapsulates serial data into packets and transports it over 802.11b/g/n wireless networks. By connecting two WI232+ units via a network, virtual serial connections can be extended across your facility or around the world.
