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 combinesaprocessor,
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.
Fordesignerswho wishtocustomize theuserinterfaceby 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.
The Wi232 device server has the following capabilities:
•Communication between TCP and UDP to serial.
•Wireless interface (802.11b or Ethernet interface.
•Upgradeable firmware.
•SNMP monitoring.
•Connects devices through a TCP or UDP data channel to computers or to another device server.
•Contains a web server allowing presentation of custom content and easy configuration through the
browser.
Some of the devices are:
•ATM Machines
•CNC Controllers
•Data Collection Devices
•Universal Power Supply (UPS) Management Units
•Telecommunications Equipment
•Data Display Devices
•Security Alarms and Access Control Devices
•Handheld Instruments
•Fire Control Panels
•Time/Attendance Clocks and Terminals
•Virtually any RS-232 serial device
