Overview - GridConnect Wi232 User Manual

1. Overview

Wi232 is a wireless embedded device server that provides serial-to-wireless network connectivity. Wi232
allows virtually any RS232 serial device or equipment to be remotely accessed, controlled, monitored or
shared on an 802.11b wireless network.
The Wi232 functions independently of a PC, providing a fully integrated solution that combines a processor,
memory, 802.11b transceiver, Ethernet port, and a high-speed serial port into a single compact module. It
includes an operating system, an embedded Web server, full TCP/IP protocol stack and WEP/WPA security.
In addition, the Wi232 supports numerous other network communication protocols, including ARP, UDP,
TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.
For designers who wish to customize the user interface by employing common and familiar tools, the Wi232
serves applets to a Web browser, resulting in interactive Web pages. This customization of HTML Web
pages and configuration screens tailors the Wi232 to fit unique requirements.
